Meet the Winners of Startups in Asia

Phineas Redux by Anthony Trollope, is part of the HackerNoon Books Series. You can jump to any chapter in this book . AT LAST—AT LAST. here AT LAST—AT LAST. As he took his ticket Phineas sent his message to the Prime Minister, taking that personage literally at his word. The message was, No. When writing it in the office it seemed to him to be uncourteous, but he found it difficult to add any other words that should make it less so. He supplemented it with a letter on his arrival in London, in which he expressed his regret that certain circumstances of his life which had occurred during the last month or two made him unfit to undertake the duties of the very pleasant office to which Mr. Gresham had kindly offered to appoint him. That done, he remained in town but one night, and then set his face again towards Matching. When he reached that place it was already known that he had refused to accept Mr. Gresham's offer, and he was met at once with regrets and condolements. "I am sorry that it must be so," said the Duke,—who was sorry, for he liked the man, but who said not a word more upon the subject. "You are still young, and will have further opportunities," said Lord Cantrip, "but I wish that you could have consented to come back to your old chair." "I hope that at any rate we shall not have you against us," said Sir Harry Coldfoot. Among themselves they declared one to another that he had been so completely upset by his imprisonment and subsequent trial as to be unable to undertake the work proposed to him. "It is not a very nice thing, you know, to be accused of murder," said Sir Gregory, "and to pass a month or two under the full conviction that you are going to be hung. He'll come right again some day. I only hope it may not be too late." "So you have decided for freedom?" said Madame Goesler to him that evening,—the evening of the day on which he had returned. "Yes, indeed." "I have nothing to say against your decision now. No doubt your feelings have prompted you right." "Now that it is done, of course I am full of regrets," said Phineas. "That is simple human nature, I suppose." "Simple enough; and the worst of it is that I cannot quite explain even to myself why I have done it. Every friend I had in the world told me that I was wrong, and yet I could not help myself. The thing was offered to me, not because I was thought to be fit for it, but because I had become wonderful by being brought near to a violent death! I remember once, when I was a child, having a rocking-horse given to me because I had fallen from the top of the house to the bottom without breaking my neck. The rocking-horse was very well then, but I don't care now to have one bestowed upon me for any such reason." "Still, if the rocking-horse is in itself a good rocking-horse—" "But it isn't." "I don't mean to say a word against your decision." "It isn't good. It is one of those toys which look to be so very desirable in the shop-windows, but which give no satisfaction when they are brought home. I'll tell you what occurred the other day. The circumstances happen to be known to me, though I cannot tell you my authority. My dear old friend Laurence Fitzgibbon, in the performance of his official duties, had to give an opinion on a matter affecting an expenditure of some thirty or forty thousand pounds of public money. I don't think that Laurence has generally a very strong bias this way or that on such questions, but in the case in question he took upon himself to be very decided. He wrote, or got some one to write, a report proving that the service of the country imperatively demanded that the money should be spent, and in doing so was strictly within his duty." "I am glad to hear that he can be so energetic." "The Chancellor of the Exchequer got hold of the matter, and told Fitzgibbon that the thing couldn't be done." "That was all right and constitutional, I suppose." "Quite right and constitutional. But something had to be said about it in the House, and Laurence, with all his usual fluency and beautiful Irish brogue, got up and explained that the money would be absolutely thrown away if expended on a purpose so futile as that proposed. I am assured that the great capacity which he has thus shown for official work and official life will cover a multitude of sins." "You would hardly have taken Mr. Fitzgibbon as your model statesman." "Certainly not;—and if the story affected him only it would hardly be worth telling. But the point of it lies in this;—that he disgusted no one by what he did. The Chancellor of the Exchequer thinks him a very convenient man to have about him, and Mr. Gresham feels the comfort of possessing tools so pliable." "Do you think that public life then is altogether a mistake, Mr. Finn?" "For a poor man I think that it is, in this country. A man of fortune may be independent; and because he has the power of independence those who are higher than he will not expect him to be subservient. A man who takes to parliamentary office for a living may live by it, but he will have but a dog's life of it." "If I were you, Mr. Finn, I certainly would not choose a dog's life." He said not a word to her on that occasion about herself, having made up his mind that a certain period of the following day should be chosen for the purpose, and he had hardly yet arranged in his mind what words he would use on that occasion. It seemed to him that there would be so much to be said that he must settle beforehand some order of saying it. It was not as though he had merely to tell her of his love. There had been talk of love between them before, on which occasion he had been compelled to tell her that he could not accept that which she offered to him. It would be impossible, he knew, not to refer to that former conversation. And then he had to tell her that he, now coming to her as a suitor and knowing her to be a very rich woman, was himself all but penniless. He was sure, or almost sure, that she was as well aware of this fact as he was himself; but, nevertheless, it was necessary that he should tell her of it,—and if possible so tell her as to force her to believe him when he assured her that he asked her to be his wife, not because she was rich, but because he loved her. It was impossible that all this should be said as they sat side by side in the drawing-room with a crowd of people almost within hearing, and Madame Goesler had just been called upon to play, which she always did directly she was asked. He was invited to make up a rubber, but he could not bring himself to care for cards at the present moment. So he sat apart and listened to the music. If all things went right with him to-morrow that music,—or the musician who made it,—would be his own for the rest of his life. Was he justified in expecting that she would give him so much? Of her great regard for him as a friend he had no doubt. She had shown it in various ways, and after a fashion that had made it known to all the world. But so had Lady Laura regarded him when he first told her of his love at Loughlinter. She had been his dearest friend, but she had declined to become his wife; and it had been partly so with Violet Effingham, whose friendship to him had been so sweet as to make him for a while almost think that there was more than friendship. Marie Goesler had certainly once loved him;—but so had he once loved Laura Standish. He had been wretched for a while because Lady Laura had refused him. His feelings now were altogether changed, and why should not the feelings of Madame Goesler have undergone a similar change? There was no doubt of her friendship; but then neither was there any doubt of his for Lady Laura. And in spite of her friendship, would not revenge be dear to her,—revenge of that nature which a slighted woman must always desire? He had rejected her, and would it not be fair also that he should be rejected? "I suppose you'll be in your own room before lunch to-morrow," he said to her as they separated for the night. It had come to pass from the constancy of her visits to Matching in the old Duke's time, that a certain small morning-room had been devoted to her, and this was still supposed to be her property,—so that she was not driven to herd with the public or to remain in her bedroom during all the hours of the morning. "Yes," she said; "I shall go out immediately after breakfast, but I shall soon be driven in by the heat, and then I shall be there till lunch. The Duchess always comes about half-past twelve, to complain generally of the guests." She answered him quite at her ease, making arrangement for privacy if he should desire it, but doing so as though she thought that he wanted to talk to her about his trial, or about politics, or the place he had just refused. Surely she would hardly have answered him after such a fashion had she suspected that he intended to ask her to be his wife. At a little before noon the next morning he knocked at her door, and was told to enter. "I didn't go out after all," she said. "I hadn't courage to face the sun." "I saw that you were not in the garden." "If I could have found you I would have told you that I should be here all the morning. I might have sent you a message, only—only I didn't." "I have come—" "I know why you have come." "I doubt that. I have come to tell you that I love you." "Oh Phineas;—at last, at last!" And in a moment she was in his arms. It seemed to him that from that moment all the explanations, and all the statements, and most of the assurances were made by her and not by him. After this first embrace he found himself seated beside her, holding her hand. "I do not know that I am right," said he. "Why not right?" "Because you are rich and I have nothing." "If you ever remind me of that again I will strike you," she said, raising up her little fist and bringing it down with gentle pressure on his shoulder. "Between you and me there must be nothing more about that. It must be an even partnership. There must be ever so much about money, and you'll have to go into dreadful details, and make journeys to Vienna to see that the houses don't tumble down;—but there must be no question between you and me of whence it came." "You will not think that I have to come to you for that?" "Have you ever known me to have a low opinion of myself? Is it probable that I shall account myself to be personally so mean and of so little value as to imagine that you cannot love me? I know you love me. But Phineas, I have not been sure till very lately that you would ever tell me so. As for me—! Oh, heavens! when I think of it." "Tell me that you love me now." "I think I have said so plainly enough. I have never ceased to love you since I first knew you well enough for love. And I'll tell you more,—though perhaps I shall say what you will think condemns me;—you are the only man I ever loved. My husband was very good to me,—and I was, I think, good to him. But he was many years my senior, and I cannot say I loved him,—as I do you." Then she turned to him, and put her head on his shoulder. "And I loved the old Duke, too, after a fashion. But it was a different thing from this. I will tell you something about him some day that I have never yet told to a human being." "Tell me now." "No; not till I am your wife. You must trust me. But I will tell you," she said, "lest you should be miserable. He asked me to be his wife." "The old Duke?" "Yes, indeed, and I refused to be a—duchess. Lady Glencora knew it all, and, just at the time I was breaking my heart,—like a fool, for you! Yes, for you! But I got over it, and am not broken-hearted a bit. Oh, Phineas, I am so happy now." Exactly at the time she had mentioned on the previous evening, at half-past twelve, the door was opened, and the Duchess entered the room. "Oh dear," she exclaimed, "perhaps I am in the way; perhaps I am interrupting secrets." "No, Duchess." "Shall I retire? I will at once if there be anything confidential going on." "It has gone on already, and been completed," said Madame Goesler rising from her seat. "It is only a trifle. Mr. Finn has asked me to be his wife." "Well?" "I couldn't refuse Mr. Finn a little thing like that." "I should think not, after going all the way to Prague to find a latch-key! I congratulate you, Mr. Finn, with all my heart." "Thanks, Duchess." "And when is it to be?" "We have not thought about that yet, Mr. Finn,—have we?" said Madame Goesler. "Adelaide Palliser is going to be married from here some time in the autumn," said the Duchess, "and you two had better take advantage of the occasion." This plan, however, was considered as being too rapid and rash. Marriage is a very serious affair, and many things would require arrangement. A lady with the wealth which belonged to Madame Goesler cannot bestow herself off-hand as may a curate's daughter, let her be ever so willing to give her money as well as herself. It was impossible that a day should be fixed quite at once; but the Duchess was allowed to understand that the affair might be mentioned. Before dinner on that day every one of the guests at Matching Priory knew that the man who had refused to be made Under-Secretary of State had been accepted by that possessor of fabulous wealth who was well known to the world as Madame Goesler of Park Lane. "I am very glad that you did not take office under Mr. Gresham," she said to him when they first met each other again in London. "Of course when I was advising you I could not be sure that this would happen. Now you can bide your time, and if the opportunity offers you can go to work under better auspices."

AT LAST—AT LAST.

The Way We Live Now by Anthony Trollope, is part of the HackerNoon Books Series. You can jump to any chapter in this book . PAUL MONTAGUE'S VINDICATION. here PAUL MONTAGUE'S VINDICATION. It is hoped that the reader need hardly be informed that Hetta Carbury was a very miserable young woman as soon as she decided that duty compelled her to divide herself altogether from Paul Montague. I think that she was irrational; but to her it seemed that the offence against herself,—the offence against her own dignity as a woman,—was too great to be forgiven. There can be no doubt that it would all have been forgiven with the greatest ease had Paul told the story before it had reached her ears from any other source. Had he said to her,—when her heart was softest towards him,—I once loved another woman, and that woman is here now in London, a trouble to me, persecuting me, and her history is so and so, and the history of my love for her was after this fashion, and the history of my declining love is after that fashion, and of this at any rate you may be sure, that this woman has never been near my heart from the first moment in which I saw you;—had he told it to her thus, there would not have been an opening for anger. And he doubtless would have so told it, had not Hetta's brother interfered too quickly. He was then forced to exculpate himself, to confess rather than to tell his own story,—and to admit facts which wore the air of having been concealed, and which had already been conceived to be altogether damning if true. It was that journey to Lowestoft, not yet a month old, which did the mischief,—a journey as to which Hetta was not slow in understanding all that Roger Carbury had thought about it, though Roger would say nothing of it to herself. Paul had been staying at the seaside with this woman in amicable intimacy,—this horrid woman,—in intimacy worse than amicable, and had been visiting her daily at Islington! Hetta felt quite sure that he had never passed a day without going there since the arrival of the woman; and everybody would know what that meant. And during this very hour he had been,—well, perhaps not exactly making love to herself, but looking at her and talking to her, and behaving to her in a manner such as could not but make her understand that he intended to make love to her. Of course they had really understood it, since they had met at Madame Melmotte's first ball, when she had made a plea that she could not allow herself to dance with him more than,—say half-a-dozen times. Of course she had not intended him then to know that she would receive his love with favour; but equally of course she had known that he must so feel it. She had not only told herself, but had told her mother, that her heart was given away to this man; and yet the man during this very time was spending his hours with a—woman, with a strange American woman, to whom he acknowledged that he had been once engaged. How could she not quarrel with him? How could she refrain from telling him that everything must be over between them? Everybody was against him,—her mother, her brother, and her cousin: and she felt that she had not a word to say in his defence. A horrid woman! A wretched, bad, bold American intriguing woman! It was terrible to her that a friend of hers should ever have attached himself to such a creature;—but that he should have come to her with a second tale of love long, long before he had cleared himself from the first;—perhaps with no intention of clearing himself from the first! Of course she could not forgive him! No;—she would never forgive him. She would break her heart for him. That was a matter of course; but she would never forgive him. She knew well what it was that her mother wanted. Her mother thought that by forcing her into a quarrel with Montague she would force her also into a marriage with Roger Carbury. But her mother would find out that in that she was mistaken. She would never marry her cousin, though she would be always ready to acknowledge his worth. She was sure now that she would never marry any man. As she made this resolve she had a wicked satisfaction in feeling that it would be a trouble to her mother;—for though she was altogether in accord with Lady Carbury as to the iniquities of Paul Montague she was not the less angry with her mother for being so ready to expose those iniquities. Oh, with what slow, cautious fingers, with what heartbroken tenderness did she take out from its guardian case the brooch which Paul had given her! It had as yet been an only present, and in thanking him for it, which she had done with full, free-spoken words of love, she had begged him to send her no other, so that that might ever be to her,—to her dying day,—the one precious thing that had been given to her by her lover while she was yet a girl. Now it must be sent back;—and, no doubt, it would go to that abominable woman! But her fingers lingered over it as she touched it, and she would fain have kissed it, had she not told herself that she would have been disgraced, even in her solitude, by such a demonstration of affection. She had given her answer to Paul Montague; and, as she would have no further personal correspondence with him, she took the brooch to her mother with a request that it might be returned. "Of course, my dear, I will send it back to him. Is there nothing else?" "No, mamma;—nothing else. I have no letters, and no other present. You always knew everything that took place. If you will just send that back to him,—without a word. You won't say anything,—will you, mamma?" "There is nothing for me to say if you have really made him understand you." "I think he understood me, mamma. You need not doubt about that." "He has behaved very, very badly,—from the beginning," said Lady Carbury. But Hetta did not really think that the young man had behaved very badly from the beginning, and certainly did not wish to be told of his misbehaviour. No doubt she thought that the young man had behaved very well in falling in love with her directly he saw her;—only that he had behaved so badly in taking Mrs. Hurtle to Lowestoft afterwards! "It's no good talking about that, mamma. I hope you will never talk of him any more." "He is quite unworthy," said Lady Carbury. "I can't bear to—have him—abused," said Hetta sobbing. "My dear Hetta, I have no doubt this has made you for the time unhappy. Such little accidents do make people unhappy—for the time. But it will be much for the best that you should endeavour not to be so sensitive about it. The world is too rough and too hard for people to allow their feelings full play. You have to look out for the future, and you can best do so by resolving that Paul Montague shall be forgotten at once." "Oh, mamma, don't. How is a person to resolve? Oh, mamma, don't say any more." "But, my dear, there is more that I must say. Your future life is before you, and I must think of it, and you must think of it. Of course you must be married." "There is no of course at all." "Of course you must be married," continued Lady Carbury, "and of course it is your duty to think of the way in which this may be best done. My income is becoming less and less every day. I already owe money to your cousin, and I owe money to Mr. Broune." "Money to Mr. Broune!" "Yes,—to Mr. Broune. I had to pay a sum for Felix which Mr. Broune told me ought to be paid. And I owe money to tradesmen. I fear that I shall not be able to keep on this house. And they tell me,—your cousin and Mr. Broune,—that it is my duty to take Felix out of London,—probably abroad." "Of course I shall go with you." "It may be so at first; but, perhaps, even that may not be necessary. Why should you? What pleasure could you have in it? Think what my life must be with Felix in some French or German town!" "Mamma, why don't you let me be a comfort to you? Why do you speak of me always as though I were a burden?" "Everybody is a burden to other people. It is the way of life. But you,—if you will only yield in ever so little,—you may go where you will be no burden, where you will be accepted simply as a blessing. You have the opportunity of securing comfort for your whole life, and of making a friend, not only for yourself, but for me and your brother, of one whose friendship we cannot fail to want." "Mamma, you cannot really mean to talk about that now?" "Why should I not mean it? What is the use of indulging in high-flown nonsense? Make up your mind to be the wife of your cousin Roger." "This is horrid," said Hetta, bursting out in her agony. "Cannot you understand that I am broken-hearted about Paul, that I love him from my very soul, that parting from him is like tearing my heart in pieces? I know that I must, because he has behaved so very badly,—and because of that wicked woman! And so I have. But I did not think that in the very next hour you would bid me give myself to somebody else! I will never marry Roger Carbury. You may be quite—quite sure that I shall never marry any one. If you won't take me with you when you go away with Felix, I must stay behind and try and earn my bread. I suppose I could go out as a nurse." Then, without waiting for a reply she left the room and betook herself to her own apartment. Lady Carbury did not even understand her daughter. She could not conceive that she had in any way acted unkindly in taking the opportunity of Montague's rejection for pressing the suit of the other lover. She was simply anxious to get a husband for her daughter,—as she had been anxious to get a wife for her son,—in order that her child might live comfortably. But she felt that whenever she spoke common sense to Hetta, her daughter took it as an offence, and flew into tantrums, being altogether unable to accommodate herself to the hard truths of the world. Deep as was the sorrow which her son brought upon her, and great as was the disgrace, she could feel more sympathy for him than for the girl. If there was anything that she could not forgive in life it was romance. And yet she, at any rate, believed that she delighted in romantic poetry! At the present moment she was very wretched; and was certainly unselfish in her wish to see her daughter comfortably settled before she commenced those miserable roamings with her son which seemed to be her coming destiny. In these days she thought a good deal of Mr. Broune's offer, and of her own refusal. It was odd that since that refusal she had seen more of him, and had certainly known much more of him than she had ever seen or known before. Previous to that little episode their intimacy had been very fictitious, as are many intimacies. They had played at being friends, knowing but very little of each other. But now, during the last five or six weeks,—since she had refused his offer,—they had really learned to know each other. In the exquisite misery of her troubles, she had told him the truth about herself and her son, and he had responded, not by compliments, but by real aid and true counsel. His whole tone was altered to her, as was hers to him. There was no longer any egregious flattery between them,—and he, in speaking to her, would be almost rough to her. Once he had told her that she would be a fool if she did not do so and so. The consequence was that she almost regretted that she had allowed him to escape. But she certainly made no effort to recover the lost prize, for she told him all her troubles. It was on that afternoon, after her disagreement with her daughter, that Marie Melmotte came to her. And, on that same evening, closeted with Mr. Broune in her back room, she told him of both occurrences. "If the girl has got the money—," she began, regretting her son's obstinacy. "I don't believe a bit of it," said Broune. "From all that I can hear, I don't think that there is any money. And if there is, you may be sure that Melmotte would not let it slip through his fingers in that way. I would not have anything to do with it." "You think it is all over with the Melmottes?" "A rumour reached me just now that he had been already arrested." It was now between nine and ten in the evening. "But as I came away from my room, I heard that he was down at the House. That he will have to stand a trial for forgery, I think there cannot be a doubt, and I imagine that it will be found that not a shilling will be saved out of the property." "What a wonderful career it has been!" "Yes,—the strangest thing that has come up in our days. I am inclined to think that the utter ruin at this moment has been brought about by his reckless personal expenditure." "Why did he spend such a lot of money?" "Because he thought that he could conquer the world by it, and obtain universal credit. He very nearly succeeded too. Only he had forgotten to calculate the force of the envy of his competitors." "You think he has committed forgery?" "Certainly, I think so. Of course we know nothing as yet." "Then I suppose it is better that Felix should not have married her." "Certainly better. No redemption was to have been had on that side, and I don't think you should regret the loss of such money as his." Lady Carbury shook her head, meaning probably to imply that even Melmotte's money would have had no bad odour to one so dreadfully in want of assistance as her son. "At any rate do not think of it any more." Then she told him her grief about Hetta. "Ah, there," said he, "I feel myself less able to express an authoritative opinion." "He doesn't owe a shilling," said Lady Carbury, "and he is really a fine gentleman." "But if she doesn't like him?" "Oh, but she does. She thinks him to be the finest person in the world. She would obey him a great deal sooner than she would me. But she has her mind stuffed with nonsense about love." "A great many people, Lady Carbury, have their minds stuffed with that nonsense." "Yes;—and ruin themselves with it, as she will do. Love is like any other luxury. You have no right to it unless you can afford it. And those who will have it when they can't afford it, will come to the ground like this Mr. Melmotte. How odd it seems! It isn't a fortnight since we all thought him the greatest man in London." Mr. Broune only smiled, not thinking it worth his while to declare that he had never held that opinion about the late idol of Abchurch Lane. On the following morning, very early, while Melmotte was still lying, as yet undiscovered, on the floor of Mr. Longestaffe's room, a letter was brought up to Hetta by the maid-servant, who told her that Mr. Montague had delivered it with his own hands. She took it greedily, and then repressing herself, put it with an assumed gesture of indifference beneath her pillow. But as soon as the girl had left the room she at once seized her treasure. It never occurred to her as yet to think whether she would or would not receive a letter from her dismissed lover. She had told him that he must go, and go for ever, and had taken it for granted that he would do so,—probably willingly. No doubt he would be delighted to return to the American woman. But now that she had the letter, she allowed no doubt to come between her and the reading of it. As soon as she was alone she opened it, and she ran through its contents without allowing herself a moment for thinking, as she went on, whether the excuses made by her lover were or were not such as she ought to accept. Dearest Hetta, I think you have been most unjust to me, and if you have ever loved me I cannot understand your injustice. I have never deceived you in anything, not by a word, or for a moment. Unless you mean to throw me over because I did once love another woman, I do not know what cause of anger you have. I could not tell you about Mrs. Hurtle till you had accepted me, and, as you yourself must know, I had had no opportunity to tell you anything afterwards till the story had reached your ears. I hardly know what I said the other day, I was so miserable at your accusation. But I suppose I said then, and I again declare now, that I had made up my mind that circumstances would not admit of her becoming my wife before I had ever seen you, and that I have certainly never wavered in my determination since I saw you. I can with safety refer to Roger as to this, because I was with him when I so determined, and made up my mind very much at his instance. This was before I had ever even met you. If I understand it all right you are angry because I have associated with Mrs. Hurtle since I so determined. I am not going back to my first acquaintance with her now. You may blame me for that if you please,—though it cannot have been a fault against you. But, after what had occurred, was I to refuse to see her when she came to England to see me? I think that would have been cowardly. Of course I went to her. And when she was all alone here, without a single other friend, and telling me that she was unwell, and asking me to take her down to the seaside, was I to refuse? I think that that would have been unkind. It was a dreadful trouble to me. But of course I did it. She asked me to renew my engagement. I am bound to tell you that, but I know in telling you that it will go no farther. I declined, telling her that it was my purpose to ask another woman to be my wife. Of course there has been anger and sorrow,—anger on her part and sorrow on mine. But there has been no doubt. And at last she yielded. As far as she was concerned my trouble was over,—except in so far that her unhappiness has been a great trouble to me,—when, on a sudden, I found that the story had reached you in such a form as to make you determined to quarrel with me! Of course you do not know it all, for I cannot tell you all without telling her history. But you know everything that in the least concerns yourself, and I do say that you have no cause whatever for anger. I am writing at night. This evening your brooch was brought to me with three or four cutting words from your mother. But I cannot understand that if you really love me, you should wish to separate yourself from me,—or that, if you ever loved me, you should cease to love me now because of Mrs. Hurtle. I am so absolutely confused by the blow that I hardly know what I am writing, and take first one outrageous idea into my head and then another. My love for you is so thorough and so intense that I cannot bring myself to look forward to living without you, now that you have once owned that you have loved me. I cannot think it possible that love, such as I suppose yours must have been, could be made to cease all at a moment. Mine can't. I don't think it is natural that we should be parted. If you want corroboration of my story go yourself to Mrs. Hurtle. Anything is better than that we both should be broken-hearted. Yours most affectionately, Paul Montague.

PAUL MONTAGUE'S VINDICATION.

229 Stories To Learn About Economics

Intro Secure or private file storage? What is the difference? If your application provides secure file handling, it means that only you and the application you are relying on own your data. e.g., Dropbox and Google Drive. But, if you need true privacy and don’t want the company you rely on to share or sell your files with a 3rd party, you need to think about moving to private solutions like Tresorit or Sharekey. In this article, I will  try to explain how to speed up file uploading for private applications. Here is the image illustrating the process of how app private file uploading should work. Intro about the file uploading process File uploading is a trivial and pretty common task for web development. There are plenty of articles about how to upload files using JavaScript from the web. And here, I will explain a simplified mechanism of how to do it. If we are talking about the general approach of file uploading, it consists of several steps: Reading files from devices Preparing files for uploading Uploading a file. If we are talking about the 1st and 3rd points, the approach is quite clear. Let’s add some notes about the 2nd point: Here, to exclude problems, if somewhere in the process of uploading a file, the error is thrown, the process of uploading should be restarted from scratch. Also, if you are going to transmit huge files through the network, you can face performance issues and even get a 413 error (Large payload). The solution to walk around such issues is quite simple: we need to just split the file into chunks. After this, we can add encryption to encrypt each chunk, and we are good to go. Encryption Encryption is the heart of the private application. In short, encryption is a way of scrambling data so that only authorized parties can understand the information. It helps to hide your data from anyone who has no access to it. JS, like many other programming languages, brings you the possibility to add encryption to your application. But a bit differently. Commonly the process of encryption is based on manipulating binary data. Traditionally the JavaScript language didn’t really support interaction with binary data. Sure, there were strings, but they really abstracted the underlying data storage mechanism. There were also arrays, but those can contain values of any type and aren’t appropriate for representing binary buffers. Eventually, the ArrayBuffer object was created and now is the core part of the language. An instance of ArrayBuffer represents a buffer of binary data that is of fixed length and cannot be resized. Instead, a “view” into the buffer must first be created. Due to the ambiguity of what binary data can mean, we need to use a view to read and write to the underlying buffer. There are several of these views available in JavaScript e.g. , Uint8Array Int8Array… Why did we mention it here? The first thing is that to encrypt our file, we need to first represent it as and then manipulate its bytes in order to make it impossible to understand by a third party. And the second thing is SharedArrayBuffer(but this will be sooner). TypedArray Okay, we finished with the representation of the file. The one thing left is the process of encryption. I don’t think this is the right article to dive deep into the nuances of the encryption process. Let’s just use some open-source solution for encryption. In this, I will use the package, which is as close as possible to the original C implementation and which is quite easy to use. tweetNaCL.js So let’s start implementation and see what we can optimize. First steps and the first problems. Let’s start with the file reading process, which is quite straightforward. Let’s say we have input with type which has id=”file_handler”. file let chunksQueue = [];

const fileInput = document.getElementById('file_handler');

fileInput.addEventListener('change', function () {
  const file = fileInput.files[0];

  readFile(file).then((res) => {
    const chunksAmount = getChunksAmount(res.length);
    chunksQueue = getChunksQueue(chunksAmount);
    sendChunk(res).catch((e) => console.log(e));
  });
}); The method for reading files is Uint8Array, which is the preferred format for encryption. function readFile(file) {
  return new Promise((resolve) => {
    const fileReader = new FileReader();

    fileReader.onload = function () {
      const data = fileReader.result;
      const fileUint8Array = new Uint8Array(data);

      resolve(fileUint8Array);
    };

    fileReader.readAsArrayBuffer(file);
  });
} Also, let’s define - the size of one file chunk. This size will be calculated like . Based on chunksAmount, we will organize chunksQueue, which will contain file chunks that should be transferred to the server. CHUNK_SIZE Math.ceil(file.size / CHUNK_SIZE) function getChunksAmount(fileSize) { return Math.ceil(fileSize / CHUNK_SIZE) } 

const getChunksQueue = (chunksQuantity) => {
  return new Array(chunksQuantity).fill().map((_, index) => index);
}; function, which is responsible for encrypting, uploading, and retrying uploading in case of error: sendChunk async function sendChunk(file, fileName) {
  if (!chunksQueue.length)
    return;

  const chunkId = chunksQueue.shift();
  const begin = chunkId * CHUNK_SIZE;
  const chunk = file.slice(begin, begin + CHUNK_SIZE);

  const encryptedChunk = encrypt(chunk, secretKey);

  upload({ fileChunk: encryptedChunk, fileName, chunkId })
    .then(() => {
      sendChunk(file, fileName);
    })
    .catch(() => {
      chunksQueue.unshift(chunkId);
    });
} is the function for encrypting chunks: encrypt function encrypt(chunk, secretKey) {
  // creating nonce which should also be transferred to server, but not in this article
  const nonce = nacl.randomBytes(24);

  // chunk encrypted with nonce and secret key
  const encryptedChunk = nacl.secretbox(chunk, nonce, secretKey);

  // base64 encoded typed array to be sent to the server
  return nacl.util.encodeBase64(encryptedChunk);
} Don’t forget to create the user’s secretKey, which will be used for encrypting and decrypting files: const secretKey = nacl.randomBytes(32); And the last client function - the function for uploading file chunks to the server: async function upload({ fileChunk, fileName, chunkId }) {
  return fetch(`${BACKEND_URL}/upload`, {
    method: 'POST',
    body: JSON.stringify({ fileChunk, fileName, chunkId }),
    headers: {
      'Content-Type': 'application/json',
    },
  })
    .then(response => response.json())
    .then(res => {
      if (res.status === 200)
        return 'ok'

      console.error('Server Error');
  });
} The last step will be handling file chunks on the server. Firstly let’s create a simple server.js file that will be responsible for running the express server.  There would be two endpoints: one for serving the client static index.html file and another one for the API route for uploading file chunks. All chunks will be stored on the filesystem related folder(uploaded). // server.js
const express = require('express');
const path = require('path');
const fs = require('fs');
const bodyParser = require('body-parser');

const app = express();

const hostname = '127.0.0.1';
const port = 5000;

// increase memory for request to exclude 413 error
app.use(express.json({ limit: '500mb' }));
// for parsing body of request
app.use(bodyParser.json());
// for accessing js files from index.html
app.use(express.static('public'));

app.get('/', (req, res) => {
  res.sendFile(path.join(__dirname, './index.html'));
});

app.post('/upload', (req, res) => {
  const { fileChunk, fileName, chunkId } = req.body;
  const directoryPath = path.join(__dirname, `./uploaded/${fileName}`);

  // create folder for fileChunks in the file system
  fs.mkdir(directoryPath, (e) => {
    // if folder already exists, do not throw error
    if (e && e.code !== 'EEXIST') {
      console.error(e);

      res.status(500).send({ status: 500, error: e.message });
    }

    // writing of file chunk into created file folder
    fs.writeFile(path.join(directoryPath, `./${chunkId}`), fileChunk, (e, bytes) => {
      if (e)
        res.status(500).send({ status: 500, message: e.message });
      else
        res.status(200).send({ status: 200, message: 'Success' });
      });
  });
});

app.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
}); Looking into the proposed approach, we can notice that encryption of the chunk is happening for each chunk which can affect UI in case of performance. As said in the previous encryption point, encryption in JS is a manipulation of TypedArrays. In programming, we can only manipulate arrays data using a loop. Looping has a negative effect on the event loop (creepy-sounding) which finally may reduce I/O responsiveness. synchronously, So in some cases, when the file is too huge, encryption of its chunks may stop the web page from responding for some time. To avoid such behavior, we need to transmit encryption tasks to another place. We can try to make it asynchronous, but the best way will be to give this job to another thread. Parallelism Browser JavaScript has no single, bespoke implementation like most other programming languages do. There are several engines that are used in different web browsers, like v8 in Chrome and SpiderMonkey in Firefox. But most of them have Web Workers, which are mainly used for archiving parallelism. There is more than one type of Web Workers (e.g., SharedWorker, ServiceWorker). The simplest one is the Dedicated Worker, which will be used in the current article. The main difference between Dedicated Worker and others is that dedicated worker is only accessible by the script that has called it. Firstly, let’s add headers to our express static response on the server, so the client can access file: worker.js app.use(express.static(
  'public', {
    setHeaders: function(res) {
      // heade necessary for accessing worker file from the client
      res.set('Cross-Origin-Embedder-Policy', 'require-corp');
    }
  }
)); On the client, we need to create a worker instance and change the logic of to use workers for encryption instead of the main process. sendChunk // instanciating worker
const worker = new Worker("worker.js");

async function sendChunk(file, fileName) {
  if (!chunksQueue.length)
    return;

  const chunkId = chunksQueue.shift();
  const begin = chunkId * CHUNK_SIZE;
  const chunk = file.slice(begin, begin + CHUNK_SIZE);

  worker.onmessage = (msg) => {
    const { encryptedChunk: fileChunk } = msg.data;

    upload({
      fileChunk, 
      fileName, 
      chunkId,
     }).then(() => {
        sendChunk(file, fileName);
      }).catch(() => {
        chunksQueue.unshift(chunkId);
      });
   }

   worker.postMessage({ chunk });
} And finally, dedicated worker code: // worker.js
console.log('Running worker...');

if( 'function' === typeof importScripts) {
  importScripts('nacl.min.js');
  importScripts('nacl-util.min.js');
  importScripts('encrypt.js');

  const secretKey = nacl.randomBytes(32);

  self.onmessage = (msg) => {
    if (msg.data.chunk) {
      const { chunk } = msg.data;
      const encryptedChunk = encrypt(chunk, secretKey)

      postMessage({ encryptedChunk });
    }
  }
} We had a very long journey, so let’s try to analyze what we had at that moment and try to find some clips. Here is this example where we moved heavy synchronous calculations inside the worker so it would not block our main process. But, if we look through the current code, we can find out that we are using message-passing API to pass chunks of the file to the worker. This can slow down the performance of the uploading process because each time, file chunks are cloned to the worker. What if we could use something like shared memory, to which our worker will have access same as the main process? Shared Memory class allows you to share memory between two threads without depending on the message passing. It is also the same object as ArrayBuffer mentioned in the Encryption point, which has only one difference - it is shared between all workers. Data gets sent to and from the worker by using the method, and certain types are so-called transferable objects that are transferred from one context to another with a zero-copy operation, resulting in high performance. SharedArrayBuffer postMessage() To better understand how we can use this, let’s edit our previous example. As you can see, even with the usage of shared memory, we still are transferring data between the worker and the main process . This can be solved by using another shared memory for an encrypted object or just moving a request to API inside the worker. (illustrated on 3-rd image, red arrow) In this article, we will use 2nd approach. So our workflow will be transformed into: But when you try to use SharedArrayBuffer, you will find that you need to copy the file Uint8Array into SharedArrayBuffer, as SharedArrayBuffer is just a point to the memory, and it just accepts byteLength when it is initialized. You need to create its view and store data in it using a copy of the existing one. So copying of file Uint8Array would slow down the process of uploading. Suddenly the final solution appeared. Why not just pass the file object from the input? After refreshing a bit about what is File instance in JS, I found that the is the interface that provides information about files and allows JavaScript in a web page to access their content. So this is just a pointer to the file. So it has no file content but only refers to it. So I decided to just pass it as a message from the main process and inject file content into the worker. File Final solution According to image 5, we need to move all the logic from the main process to the worker. Only the input handler will stay: // main.js
document.addEventListener("DOMContentLoaded", () => {
  const worker = new Worker('/worker.js');

  const fileInput = document.getElementById('file_handler');

  fileInput.addEventListener('change', function () {
    const file = fileInput.files[0];

    worker.postMessage({ file });
  });
}); And worker.js: console.log('Running worker...');

if( 'function' === typeof importScripts) {
  importScripts('nacl.min.js');
  importScripts('nacl-util.min.js');
  importScripts('encrypt.js');
  importScripts('upload.js');
  importScripts('sendChunk.js');
  importScripts('readFile.js');

  let chunksQueue = [];
  const CHUNK_SIZE = 1000000;

  function getChunksAmount(fileSize) { return Math.ceil(fileSize / CHUNK_SIZE) }

  const getChunksQueue = (chunksQuantity) => {
    return new Array(chunksQuantity).fill().map((_, index) => index);
  };

  self.onmessage = (msg) => {
    if (msg.data.file) {
      const { file } = msg.data;

      readFile(file).then((res) => {
        const chunksAmount = getChunksAmount(res.length);
        chunksQueue = getChunksQueue(chunksAmount);
          sendChunk(res, file.name, chunksQueue).catch((e) => console.log(e));
        });
      }
   }
} Full source code you can find on GitHub: https://github.com/arty-ms/ParallelUpload Conclusion We can see that usage of parallelism can bring lots of effort for JS developers and can make your UI more responsible and effective, as all computation logic may be executed on the thread. When I was starting this article, according to my plan, I thought that the usage of SharedArrayBuffer would be the final solution. But in the process of writing code, I realized that it was not true. But It's worse to mention that SharedArrayBuffer is one of the core features of multithreading JS and everyone who uses workers API should be familiar with it. However, it is not useful for every case. The next article will cover the usage of wasm code in JS, one of the most underrated client tools. Sources used Multithread JavaScript.

The Third And Last Interview With Smerdyakov

Table of Contents Initialize repo using a template Initial structure of a template Adding rules using scripts from a template Write tests for the Eslint plugin Write Eslint rule Small AST explanation Final variant Updating docs using scripts Plugin publishing Connect it with your application Background I will try to write a tutorial based on my PR in the Reatom repository with a step-by-step explanation: https://github.com/artalar/Reatom/pull/488 If you want to know more, you can read the issue https://github.com/artalar/reatom/issues/487. To add a bit of context, Reatom is a state management library. Atoms are a concept in Reatom, a state management library for React. What Are the ESLint Plugins and Rules? ESLint plugins are extensions that work with the core ESLint package to enforce specific coding standards. Plugins contain a folder, which defines individual rules for enforcing these standards. rules Each module has a property that describes the and a property that defines the behavior. rule meta rule create rule's The function takes a argument, which is used to interact with the code being checked, and you can use it to define the logic of your rule, like requiring strict naming conventions for your library. create context Let’s Dive Into the Code Initialize Repo Creating a new TypeScript eslint project npx degit https://github.com/pivaszbs/typescript-template-eslint-plugin reatom-eslint-plugin Then, navigate to the new project directory, and install the dependencies with: cd reatom-eslint-plugin && npm i I want to be a good boy, so I init git. git init && git add . && git commit -m "init" Next, open the file, and locate the field. This field is essential because it will be the main entry point for your plugin when it's used. You can change it to the following: package.json name "name": "eslint-plugin-reatom" Alternatively, you can use the scoped package naming convention: "name": "@reatom/eslint-plugin" Initial Structure - scripts // some automation to concentrate on writing rules
- docs
  - rules // here will be generated by npm run add-rule files
- src
  - configs
      recommended.ts // generated config 
  - rules
      // all your rules
index.ts // Connection point to your plugin, autogenerated by scripts/lib/update-lib-index.ts 😀 In general index, files will be generated by scripts, so you don’t need to worry about it /* DON'T EDIT THIS FILE. This is generated by 'scripts/lib/update-lib-index.ts' */
import { recommended } from './configs/recommended';
import exampleRule from './rules/example-rule'

export const configs = {
    recommended
};

export const rules = {
    'example-rule': exampleRule
}; Adding Rules and Updating Docs In this repository, you'll find some convenient scripts for adding rules and updating documents. To add a new rule, you can use the following command: npm run add-rule atom-rule suggestion This will generate three sections for the new rule: documentation, tests, and actual code. We can skip the documentation section for now and focus on the last two. Write Tests As a TDD (test-driven development) enthusiast, we'll start by creating some simple tests in the file: tests/atom-rule.ts // tests/atom-rule.ts
tester.run('atom-rule', atomRule, {
    valid: [
        {
            code: 'const countAtom = atom(0, "countAtom");'
        },
    ],
    invalid: [
        {
            code: `const countAtom = atom(0);`,
            errors: [{ message: 'atom name is not defined' }]
        },
        {
            code: 'const countAtom = atom(0, "count");',
            errors: [{ message: 'atom name is defined bad'}]
        },
    ]
}); If you run the tests now, they will fail because we haven't implemented the yet. atomRule Writing the Rule The is where we define the rule's behavior. Here's a simple implementation: atomRule import { Rule } from "eslint";

const rule: Rule.RuleModule = {
  meta: {
    docs: {
      description: "Add name for every atom call", // simply describe your rule
      recommended: true, // if it's recommended, then npm run update will add it to recommmended config
    },
    type: "suggestion"
  },
  create: function (context: Rule.RuleContext): Rule.RuleListener {
    return {
        VariableDeclaration: node => { // listener for declaration, here we can specifiy more specific selector
            node.declarations.forEach(d => {
                if (d.init?.type !== 'CallExpression') return;
                if (d.init.callee.type !== 'Identifier') return;
                if (d.init.callee.name !== 'atom') return;
                if (d.id.type !== 'Identifier') return;
                // just guard everything that we don't need

                if (d.init.arguments.length <= 1) {
                    // show error in user code
                    context.report({ 
                        message: `atom name is not defined`,
                        // here we can pass what will be underlined by red/yellow line
                        node,
                    })
                }

                if (d.init.arguments[1]?.type !== 'Literal') return;
                // just another guard
                if (d.init.arguments[1].value !== d.id.name) {
                    context.report({ message: `atom name is defined bad`, node })
                }
            })
        }
    };
},
};

export default rule; It’s a simple variant, but here, we can easily understand what’s going on. For a better understanding of the AST structure of your code, you can use or simply console.log parsed nodes. https://astexplorer.net/ A Small Explanation for AST Typings Better Understanding Here's a small description of each identifier in a small example: const kek = atom(‘kek’) : a TypeScript interface that represents an identifier node in an AST. Identifier const = (‘kek’), and are Identifiers nodes. kek atom kek, atom : a TypeScript interface that represents a literal value (string, number, boolean, etc.) node in an AST. const kek = atom(‘ ’), ‘kek’ is a Literal kek Literal. : a TypeScript interface that represents a function call expression node in an abstract syntax tree (AST). CallExpression In our example, is a CallExpression, which consists of atom(‘kek’) atom - Identifier and kek - Literal. : a TypeScript interface that represents a variable declarator node in an AST VariableDeclarator In our example, the whole expression except const is VariableDeclarator kek = atom(‘kek’) : a TypeScript interface that represents a generic AST node. Node Or simply using astexplorer https://astexplorer.net/?embedable=true#/gist/7fe145026f1b15adefeb307427210d38/35f114eb5b9c4d3cb626e76aa6af7782927315ed Final Variant The final tests tester.run('atom-rule', rule, {
  valid: [
      {
          code: `
          import { atom } from '@reatom/framework'
          const countAtom = atom(0, "countAtom");
          `
      },
      {
          code: `const countAtom = atom(0);`,
      },
      {
          code: 'const countAtom = atom(0, "count");',
      },
  ],
  invalid: [
      {
          code: `
          import { atom } from '@reatom/framework'
          const countAtom = atom(0);
          `,
          errors: [{ message: 'atom "countAtom" should has a name inside atom() call', }],
          output: `
          import { atom } from '@reatom/framework'
          const countAtom = atom(0, "countAtom");
          `,
      },
      {
          code: `
          import { atom } from '@reatom/framework'
          const countAtom = atom(0, "count");
          `,
          errors: [{ message: `atom "countAtom" should be named as it's variable name, rename it to "countAtom"` }],
          output: `
          import { atom } from '@reatom/framework'
          const countAtom = atom(0, "countAtom");
          `,
      },
  ]
}); From tests, we understand that we need somehow change the source code by using our rule. How to Make Your Rule Fixable? Add a simple line to the context report. fix: fixer => fixer.replaceText(node, replaceString) - may be an actual node or range of symbols that you want to replace. node - what code you expect to see. replaceString Don’t forget to add : 'code' or : 'whitespace' for your rule meta tags. fixable fixable If you are not familiar with how to fix it with eslint, just try on your existing project. eslint --fix ./src Code Itself import { Rule } from "eslint";
import { CallExpression, Identifier, Literal, VariableDeclarator, Node } from 'estree';
import { isIdentifier, isLiteral } from "../lib";

type AtomCallExpression = CallExpression & { callee: Identifier, arguments: [Literal] | [Literal, Literal] }
type AtomVariableDeclarator = VariableDeclarator & { id: Identifier, init: AtomCallExpression }

const noname = (atomName: string) => `atom "${atomName}" should has a name inside atom() call`;
const invalidName = (atomName: string) => `atom "${atomName}" should be named as it's variable name, rename it to "${atomName}"`;

export const atomRule: Rule.RuleModule = {
    meta: {
        type: 'suggestion',
        docs: {
            recommended: true,
            description: "Add name for every atom call"
        },
        fixable: 'code'
    },
    create: function (context: Rule.RuleContext): Rule.RuleListener {
        let importedFromReatom = false;

        return {
            ImportSpecifier(node) {
                const imported = node.imported.name;
                // @ts-ignore
                const from = node.parent.source.value;
                if (from.startsWith('@reatom') && imported === 'atom') {
                    importedFromReatom = true;
                }
            },
            VariableDeclarator: d => {
                if (!isAtomVariableDeclarator(d) || !importedFromReatom) return;

                if (d.init.arguments.length === 1) {
                    reportUndefinedAtomName(context, d);
                } else if (isLiteral(d.init.arguments[1]) && d.init.arguments[1].value !== d.id.name) {
                    reportBadAtomName(context, d);
                }
            }
        };
    }
}

function isAtomCallExpression(node?: Node | null): node is AtomCallExpression {
    return node?.type === 'CallExpression' && node.callee?.type === 'Identifier' && node.callee.name === 'atom';
}

function isAtomVariableDeclarator(node: VariableDeclarator): node is AtomVariableDeclarator {
    return isAtomCallExpression(node.init) && isIdentifier(node.id);
}

function reportUndefinedAtomName(context: Rule.RuleContext, d: AtomVariableDeclarator) {
    context.report({
        message: noname(d.id.name),
        node: d,
        fix: fixer => fixer.insertTextAfter(d.init.arguments[0], `, "${d.id.name}"`)
    });
}

function reportBadAtomName(context: Rule.RuleContext, d: AtomVariableDeclarator) {
    context.report({
        message: invalidName(d.id.name),
        node: d,
        fix: fixer => fixer.replaceText(d.init.arguments[1], `"${d.id.name}"`)
    });
} As you can see, it just has better errors, type guards, and includes import checking. And, of course, I make the rule fixable. Updating the Docs To update the documents, you can use the following command: npm run update This command will update README.md and update docs for each rule (but you need to write a bit about each rule in the docs/{rule} file). Also, as I said, you don’t need to worry about the index file. Publish Step Ensure the version is in your package.json. "version": "1.0.0" Write in term if it’s not 1.0.0. npm version 1.0.0 Then just write in the root. npm publish Everything will be built and published with your defined package name. Connect It With Your Application I name my package. @reatom/eslint-plugin So, I need to install it. npm i @reatom/eslint-plugin And add to my .eslintrc config. module.exports = {
    plugins: [
        "@reatom"
    ],
// use all rules
     extends: [
        "plugin:@reatom/recommended"
     ],
    // or pick some
    rules: {
        '@reatom/atom-rule': 'error',
        // aditional rules, you can see it in PR
        '@reatom/action-rule': 'error',
        '@reatom/reatom-prefix-rule': 'error'
    }
} And everything just works (for just you should write instead everywhere). reatom-eslint-plugin “reatom” “@reatom" Conclusion In this tutorial, we walked through the process of creating an ESLint plugin for the Reatom state management library. We cover: How to write an eslint plugin in Typescript. How to cover it with tests. How to make it work with the --fix option. How to use my template. How to publish the eslint plugin.
