One Netbook is best known for its high-quality OneXPlayer branded handheld gaming PCs and mini laptops that pack a solid punch in a small form factor. Among the company’s One Netbook lineup are the One-GX 1, Netbook 4, Netbook A1, and the brand new One Netbook T1. Before the crowdfunding campaign launched on June 9th, I got my hands on the T1 and used it as my daily driver for productivity and some gaming. While the T1 is certainly a great tablet at a reasonable price, it struggles quite a lot in the gaming department and isn’t quite the most powerful device out there. The One Netbook T1 makes a lot of promises as the first tablet powered by Intel’s 12th Generation Alder Lake CPU. The company claims it can take on the latest games by utilizing the power of Intel’s new Iris Xe Graphics architecture while also being an excellent choice for artists using Lightroom and engineers using . Diving into the full specs, it is easy to see why One Netbook makes such claims. AutoCAD One Netbook T1 Technical Specs CPU: 12th Gen Intel Core i5-1240P featuring 12 cores and 16 threads, up to 4.7 GHz Graphics: Intel Iris Xe, 96 execution units, up to 1.4 GHz RAM: 16 GB DDR5 at 5000 MHz Battery: 12,000 mAh battery, lasting nine hours. Screen: 13-inch, 2160 x 1440 IPS screen at a peak brightness of 500 nits. Weight: 2.2 pounds The T1 User Experience Right out of the box, the One Netbook T1 makes a great first impression with its sleek, minimalist design that fits well in your hands. The tablet also is quite responsive, adjusting its orientation between landscape and portrait modes on the fly. Included with the T1 is an integrated kickstand, solidly built and stable enough to put the tablet anywhere you desire. At no point did I fear the tablet would topple over as the stand is large and durable. Battery life is also quite good, lasting close to its targeted nine hours for an all-day battery. Slow to Boot Up As an entry-level tablet, it gets the job done but has a few hiccups. Notably, booting up the device was sluggish. Every time I pressed the power button, the screen would stay off, and only after one or two more presses would it actually power on and launch into . Consumers in the market for a tablet want a snappy experience on the go, and the T1 struggles here. Windows 11 A Pleasantly Quiet Fan While under workloads, the T1 remains mostly quiet thanks to its nice fan, which does a great job at keeping temperatures under control. Unlike many portable devices, the T1’s fan has a pleasant whoosh sound instead of a high-pitched squeal when it has to kick into high gear. The fan is also mostly inaudible when wearing headphones which is a big plus. Solid CPU Performance Additionally, the tablet never got hot to the touch, even under the most intensive workloads. After an extended period of stress testing, the CPU’s core temperature hit a max of 66 degrees celsius in a temperature-controlled environment of 20 degrees celsius. Noise and heat are no problem for the T1 and should be a pleasant computing experience overall. Productivity and Workflow The One Netbook T1 is no slouch regarding power and performance. Benchmark Testing Plugging the T1 into the CPU-intensive Cinebench test suite gave a score of 4505, placing the i5-1240P below an Intel i7-4850HQ. For only pulling 28 watts under maximum load, the result is impressive but far from being the “most powerful tablet on the market,” per One Netbook’s marketing materials. A score of 4505 still puts the device in range of the Microsoft Surface Pro 8, which keeps the T1 competitive with Microsoft’s flagship tablet. For the artists interested in a tablet to aid their workflow, the T1 does an excellent job of responding with precision with its included pen. Writing and drawing flow naturally on the T1 screen but fail to feel as smooth and paper-like as the Microsoft Surface Pro tablet. Nitpick aside, the tablet does its primary job of creating a seamless writing experience and is serviceable enough for anyone looking to replace their existing tablet for Lightroom photo editing or general digital art. The One Netbook T1 for Gaming One Netbook makes some big claims about the T1’s gaming performance and its i5-1240P does look promising. Ultimately, the tablet fails to deliver decent performance across AAA games but doesn’t entirely lack gaming chops. Testing the i5-1240P and its integrated Iris XE 96EU integrated graphics on 3D Mark Time Spy resulted in a score of 1147 for the GPU and 3425 for the CPU. These are fine scores for a tablet but are definitely not at the same level as a able to take on the newest games. The T1 excels in gaming for smaller-scale, less intensive indie games, not AAA games like the company claims. gaming PC Elden Ring Starting the tests with FromSoftware’s latest game, , the T1 struggled to achieve 30 fps at 720p resolution at the lowest settings. Elden Ring can certainly launch, but it is an inadequate showing for a game like this where every frame counts. Elden Ring Death Stranding The better-optimized Death Stranding: Director’s Cut achieved 30 fps but only at the lowest settings and 720p resolution. This game is undoubtedly considered playable but not an overall great experience for anyone looking to have an on-the-go AAA gaming machine. Eiyuden Chronicle: Rising NatsumeAtari’s recently released JRPG indie game, Eiyuden Chronicle: Rising, had a stronger showing, achieving 60 fps at significantly cut-down graphical settings. This is where the T1 proved that it could game but only if players manage their expectations and understand that this tablet is better suited for lighter gaming workloads. While most of these games had to be cut down to 720p, the One Netbook T1’s high pixel density screen at 13 inches did manage to still look crisp enough to be playable. That said, its native 1440p resolution is far too much for the i5-1240P to handle. There does exist an i7 model that could be more suitable for gaming but as far as the i5 model is concerned, it is firmly a tablet for light productivity workloads and general day-to-day use. One Netbook T1: Is it Worth it? As a tablet, the One Netbook T1 is a good entry-level tablet and will get the job done, being more or less a copy of the Microsoft Surface Pro 8. For productivity and as an addition to your workflow, the T1 is a pleasant device, especially on the go. As an overall gaming device, don’t expect too much. However, the T1 becomes an enticing option when you consider that its price point is much lower than its competitors. One Netbook just launched its crowdfunding campaign for the T1 on IndieGoGo, and early bird pricing starts at $599 for the lowest tiered model, featuring a Pentium 8505. That’s a good step down from the $899 asking price of a Microsoft Surface Pro 8 while containing all of the functionality of its competitors. Overall, if the price is right and a well-functioning tablet is just what you’re looking for, then the One Netbook T1 is a good option.

Collaborating and partnering with over 10 Linux distributors to make a seamless virtual desktop experience, Alex is CEO of , a new virtual desktop cloud computing solution that is simplifying the virtual desktop experience. shells.com The platform lets anyone access their cloud computer from any device with a browser so you can have a Linux desktop on your Apple iPad or your Windows computer on your XBox! The team are also the previous founders and operators of Private Internet Access, one of the world’s best and most trusted VPNs. This Slogging thread by Alex Lee, Justin Roberti, Golda Velez, Zlatan Todoric and Akasha Rose occurred in 's official #amas channel, and has been edited for readability. slogging Alex Lee May 25, 2021, 2:07 PM 💚 1 👍 1 ❤ 1 Hello everyone!  Thanks, Akasha for the introduction and looking forward to talking with the Slogging community!  I also have our VP of Tech Zlatan Todoric on here too! Justin Roberti May 25, 2021, 2:17 PM Alex Lee so early virtual desktop apps for mobile were pretty unstable and seemed to bog down the device -- are you mitigating those issues by virtually hosting the OS? How do you handle lag since all requests I assume are hitting a virtually hosted OS? Are all client computers mirrored on the cloud? How do you ensure data security? Is this meant as specifically a way to open up Linux usage to a wider user base? Is it also a cloud storage solution? Lastly, are you considering doing the same for mobile devices, or are they already available? Alex Lee May 25, 2021, 2:25 PM Justin Roberti Great questions to kick off the discussion.  The operating systems are hosted in the cloud.  With the continued enhancement of internet speeds and especially mobile connections (4G, LTE, 5G), a much better experience can be expected in addition to some adjustments we have made to reduce the amount of resources required. Alex Lee May 25, 2021, 2:27 PM The virtual computers are all in the cloud so the data is all stored securely on our servers and access is secured using state of the art encryption.  Users are also encouraged to enable 2-factor authentication (which you should do on all accounts!). Alex Lee May 25, 2021, 2:28 PM When we first started, we definitely saw this as a great option for folks who were on the fence about Linux to definitely give it a try through our product since we do offer over 14 Linux distros now, but its also to just open up the desktop experience to a wider user base as you can access from any device with the proper browser (or app) and an internet connection. Alex Lee May 25, 2021, 2:30 PM Yeah, by default we are a cloud storage solution, but we are working to make the product more seamless and offer something similar to what you would see with a Dropbox.  I like to refer to us as a Dropbox on steroids as you can store but also create, edit, modify your files. Alex Lee May 25, 2021, 2:31 PM You can already access our service through mobile devices.  Here is a nice little snapshot I took the other day of my Shells machine on my Galaxy Flip 🙂 Alex Lee May 25, 2021, 2:32 PM Justin Roberti May 25, 2021, 3:06 PM Alex Lee thank you. what kind of specs do you need for the device as a user? If the industry moves toward remotely hosted OS', will everyone be moving to basic netbooks or do those devices not have the RAM to handle running the OS? Or would this lead to home/work computers with high RAM and less internal storage (a direction they are already going)? Justin Roberti May 25, 2021, 3:07 PM Alex Lee just to clarify, are users able to use your service to run Android-only apps on a PC for example? Alex Lee May 25, 2021, 3:15 PM Justin Roberti Love the interest!  Our product can be accessed from the browser so most modern browsers can handle our product. For example, I went and purchased a $200 Chromebook with 2GB RAM and I have been using this device to access my Shells machines. Our product definitely creates the option to converge devices and utilize a low-level device for all of your computing needs. Alex Lee May 25, 2021, 3:16 PM Yes, Android only apps can now be accessed from a PC or even if you want to access Android-only apps from an iPad, this is now a viable option. Justin Roberti May 25, 2021, 4:01 PM Alex Lee so, as part of the gig economy who destroyed two laptops by catastrophic spills this year, it sounds like this could be of great benefit to those of us who are our own IT department-- replacing these machines for 200 instead of $1200 or more. Correct? Is this one of the intended use cases? Justin Roberti May 25, 2021, 4:03 PM Alex Lee, how do you handle licensing for non-Linux OS? Does the user need to provide the license? Alex Lee May 25, 2021, 4:06 PM Justin Roberti Definitely that is an appealing solution to be able to use either cheaper hardware alternatives or increase the longevity of older devices.  For Windows, we offer the ability to activate your OS by providing licensing which can be paid by the month or by the year. Justin Roberti May 25, 2021, 4:10 PM Alex Lee, can you post a link to the WP or backgrounder? Alex Lee May 25, 2021, 4:12 PM We don't have an updated backgrounder to provide right now, but this is something that I can get to you later for sure! Justin Roberti May 25, 2021, 4:13 PM Alex Lee, it seems like this would be a good fit for education... but schools and even most businesses have switched over to Google docs .. which does most but not all of what MS Suite does. Is that your biggest competition? What advantages can you provide over the free Google solution? Justin Roberti May 25, 2021, 4:14 PM I still miss what I could do with local versions of PPT but I think I'm in the minority. Alex Lee May 25, 2021, 4:19 PM I don't really look at Google docs as our biggest competition.  Google docs has its benefits for sure, but we are really focused on providing the "full desktop experience" whether that is having access to the more powerful MS Suite or being able to create what you want to create or change what you want to change. Justin Roberti May 25, 2021, 4:25 PM Alex Lee, how many clients are you currently running? Are you focusing on enterprise or retail users? What are you projecting as your user growth by end of 2021? Alex Lee May 25, 2021, 4:41 PM We have servers (which is our own hardware) in 6 locations (Los Angeles, Dallas, Chicago, New York, Amsterdam, and Tokyo).  We hope to get to 80% capacity of these locations while adding more hardware and locations in the process by the end of the year!  But of course, I would love to go beyond that too. 🙂 Justin Roberti May 25, 2021, 4:51 PM Alex Lee how many current users? Alex Lee May 25, 2021, 4:54 PM Somewhere around 600 right now.  We just started up in February. Golda Velez May 25, 2021, 5:15 PM This is lovely, one would think a graphical browser could handle a shell!  Is the browser involved in rendering line by line? Can you just tunnel ssh to anywhere or only to your cloud? Or maybe I misunderstood - this is a whole ubuntu-desktop experience in the browser? Zlatan Todoric May 25, 2021, 5:29 PM Hi all. We bring them up via QEMU and then use Spice for remote desktop experience. We currently offer Windows 2019 Desktop Experience, Windows 7, Ubuntu 20.04 and Ubuntu 21.04, Debian Buster, 3 Manjaro editions, 4 openSUSE editions, Linux Mint, KDE neon user and testing, Kubuntu and Xubuntu. We also have Ubuntu and Debian servers and soon Android. More Linux distros are coming too. Zlatan Todoric May 25, 2021, 5:30 PM You can do it all in the browser, from any device that can handle modern browser or you can use our client apps too (for Windows, Mac, Linux, iOS and Android). Justin Roberti May 25, 2021, 5:33 PM Welcome Zlatan Todoric VP of Technology for Shell (I just thought I'd state that since I think it hasn't be stated yet). Justin Roberti May 25, 2021, 5:35 PM Zlatan Todoric is there a lite client download on the user end in order to be able to communicate with your remote OS on Shell? Zlatan Todoric May 25, 2021, 5:36 PM You don't need the client at all, you can just do it all in the browser. That said, the client itself is very light in nature (desktop one is written in Go and the mobile ones in Flutter but we plan to move them to Swift and Kotlin). Zlatan Todoric May 25, 2021, 5:41 PM 🔥 1 BTW, coming to your first question Justin Roberti - the virtual desktop apps for mobile (or vice versa), were unstable or heavy because virtualization (or emulation and in some instances full core) were done on the device itself. In our case, everything is offloaded to the cloud so you need just a decent internet connection and enough power to have one medium memory-hungry tab opened (average devices nowadays can handle 100 open tabs). Zlatan Todoric May 25, 2021, 5:47 PM For ssh - you can tunnel it. We also have a system in place for ssh key (which is a requirement for servers) and by default, we disable the password for ssh (as an increased step in security). Golda Velez May 25, 2021, 6:47 PM Nice - I would want it just for ssh from my phone. Zlatan Todoric May 25, 2021, 6:48 PM You can already do that :) Akasha Rose May 25, 2021, 10:49 PM Alex Lee and Zlatan Todoric - what do you define as the digital divide, and how is your service closing it? Alex Lee May 25, 2021, 10:54 PM I define the digital divide as basically the gap between those who have access to technology that enables them to go and achieve their dreams or be successful and those that do not have access. Alex Lee May 25, 2021, 10:56 PM Our service can close that gap in a variety of ways from being able to provide a desktop computing experience to someone who may only be able to afford a cheap smartphone or tablet to enhance an old or dated device which has its limitations whether it be access to Windows or just does not have the requirements to run the user's desired configuration. Alex Lee May 25, 2021, 11:00 PM We are working closely with some schools right now and providing a single environment to classrooms.  We visited a high school recently and a classroom of 20 had 5 different models of Chromebooks and HP laptops of all different ages and types.  Our product can help to provide that consistent environment to settings like this. Akasha Rose May 26, 2021, 6:24 AM What do you think the future for Linux holds? It's come a long way in the last couple of decades. Zlatan Todoric May 26, 2021, 6:58 AM Linux in one way or another dominated different fields over  time - be it supercomputers or phones or servers. Cloud desktop is the next step in the evolution of desktop experience, in the same way that the talk about cloud servers was a decade ago. There is a famous joke "The year of Linux Desktops" but with the cloud, we are seeing the move towards there as now it is easier and secure more than ever to test the most advanced systems out there. Microsoft is even having Linux in their offering and with WSL they are showing the pattern in that way. Alex Lee May 27, 2021, 3:25 AM 🔥 1 All - Thanks for the questions in the AMA.  Here is a special link for a discounted rate for those that want to try our product!  Thanks again and don't hesitate to ask us any other questions! https://www.shells.com/l/en-US/pricing?special=slogging

AMA About The Future of Virtual Desktops 

PC equipment alludes to the physical segments that make up a PC framework. There are a wide range of sorts of equipment that can be introduced inside, and associated with the outside, of a PC. Rundown of Computer Hardware Here are some basic individual PC equipment parts that you’ll regularly discover inside a cutting edge PC. These parts are quite often found inside the PC’s case, so you won’t see them except if you open the PC: Motherboard Focal Processing Unit (CPU) Arbitrary Access Memory (RAM) Power Supply Video Card Hard Drive (HDD) Solid-State Drive (SSD) Optical Drive (e.g., BD/DVD/CD drive) Card Reader (SD/SDHC, CF, and so on.) Here is some basic equipment that you may discover associated with the outside of a PC, albeit numerous tablets, workstations, and netbooks coordinate a portion of these things into their lodgings: Screen KeyBoard Mouse Battery Backup (UPS) Flash Drive Printer Speakers External Hard Drive Pen Tablet Here are some less regular individual PC equipment gadgets, either on the grounds that these pieces are presently typically incorporated into different gadgets or in light of the fact that they’ve been supplanted with fresher innovation: Sound Card Network Interface Card (NIC) Development Card (Firewire, USB, and so forth.) Hard Drive Controller Card Simple Modem Scanner Projector Floppy Disk Drive Joystick Webcam Mouthpiece Tape Drive Compressed memory drive The accompanying equipment is alluded to as network equipment, and different pieces are frequently part of a home or business organize: Computerized Modem (e.g., Cable Modem, DSL Modem, and so on.) Switch System Switch Passage Repeater Scaffold Print Server Firewall System equipment isn’t as unmistakably characterized as some different sorts of PC equipment. For instance, many home switches will frequently go about as a mix switch, switch, and firewall. Notwithstanding all the things recorded over, there’s more PC equipment called helper equipment, of which a PC may have none, or a few, of certain sorts: Fan (CPU, GPU, Case, and so on.) Warmth Sink Information Cable Force Cable CMOS Battery Daughterboard A portion of the gadgets recorded above are called fringe gadgets. A fringe gadget is a bit of equipment (regardless of whether interior or outside) that isn’t really associated with the PC’s fundamental capacity. Models incorporate a screen, video card, plate drive, and mouse. Investigating Faulty Computer Hardware PC equipment segments separately heat up and chill off as they’re utilized and afterward not utilized, implying that in the long run, each and every one will fall flat. Some may even flop simultaneously. Luckily, in any event with PCs and some PC and tablet PCs, you can supplant the non-working bit of equipment without supplanting or revamp the PC without any preparation. Here are a few assets you should look at before you go out and buy another hard drive, substitution RAM sticks, or whatever else you think might be turning sour: # MEMORY (RAM) Free Memory Test Programs How Do I Replace the Memory (RAM) in my Computer? # HARD DRIVE Free Hard Drive Testing Programs Business Hard Drive Testing Tools How Do I Replace a Hard Drive? What to Do When Your Hard Drive Is Making Noise # PC FAN The most effective method to Troubleshoot a Noisy Computer Fan CPU Fan Error: What It Is and How to Fix It In Microsoft Windows, equipment assets are overseen by Device Manager. It’s conceivable that a “flawed” bit of PC equipment is extremely just needing a gadget driver establishment or update, or for the gadget to be empowered in Device Manager. Equipment gadgets won’t work at all if the gadget is incapacitated, or may not be running appropriately if an inappropriate driver is introduced. How Do I View a Device’s Status in Device Manager in Windows? How Do I Enable a Device in Device Manager in Windows? How Do I Update Drivers in Windows? Where Can I Get Free Driver Downloads? Free Driver Updater Tools On the off chance that you conclude that some equipment needs supplanting or overhauling, discover the maker’s help site for guarantee data (in the event that it concerns you) or search for indistinguishable or updated parts that you can purchase legitimately from them. See these equipment establishment recordings for walkthroughs on introducing distinctive PC equipment, similar to a hard drive, power gracefully, motherboard, PCI card, and CPU. Hardware versus Software A PC framework isn’t finished except if there’s likewise programming, which is not the same as equipment. The product is information that is put away electronically, similar to a working framework or a video altering device, which runs on the equipment. Hardware gets its name because of the way that it’s severe with regards to adjustments, though programming is increasingly adaptable (i.e., you can without much of a stretch update or change programming).

All You Need To Know About Computer Hardware

In today’s world, the number of mobile device users is continuously growing. This entails the rapid increase in the mobile application development market. Companies around the globe launch hundreds of apps daily. They upgrade their functionality and design with the latest trends. Industry leaders regularly modernize platforms for their creation, filling them with new construction principles. Android is one of the most popular operating systems for modern devices. Smartphones, tablets, e-books, game consoles, netbooks, televisions are working on its basis. There are also wearable devices — gadgets such as Android Wear-based watches, step trackers, fitness bracelets, and glasses. However, Android mobile app development is a complicated and time-consuming task. That is why companies choose first to construct patterns to ease their work. are adapted to solve the most common problems, the main purpose of which is to describe the interaction of objects in an application. A pattern is not a complete design and cannot be directly converted to code. This is just an auxiliary framework for the task, which can significantly simplify the creation of an app. Design patterns Most developers today use an object-oriented approach to programming when working on large projects, or at least are familiar with its basic concept. It is difficult, and sometimes even impossible, to begin serious work from scratch, without using patterns in the code, or at least in the design. In this regard, programmers need to highlight key points for themselves from each project. Abstracting from any specific tasks, they build a mobile app framework for future developments. Let’s consider the three most widely used patterns for android application creation: MVC, MVP, and MVVM. Model-View-Controller Design Pattern The Model-View-Controller design pattern formed the basis for the architectural solution of the first programming environment with a graphical user interface — Smalltalk-80. MVC was first described back in 1978 by Trygve Reenskaug, who worked for some time in the Xerox PARC laboratory. The architecture of the Model-View-Controller allows you to separate the data model, user interface, and control logic into three separate components. Moreover, a change in one component does not affect the work of the rest. Using this architecture is especially convenient for teamwork on large projects. For example, when developing an application, you can separate the development of the part of the site that is responsible for data processing, absolutely not worrying about how this data will be presented. Why? Because layouts and designs for the application interface can be absolutely independently created mobile app development As for programmers, they can also share their work. For example, some developers can focus on developing the program logic, and another on designing the database structure. When using MVC, it becomes possible to distribute the work of the team, thereby increasing overall performance. MVC consists of the following entities: is generally understood as a component of data administration. In most cases, this refers to communication with databases: a selection of specific data, adding new ones, and changing existing ones. The model does not know in what form it is necessary to present the data requested from it to the user; it only performs operations with “raw” data. It should have a standardized universal interface so that one model can use any number of other subsystems any number of times. Model describes the format of data output to the user, that is, a visual representation of the data taken from the Model. It receives at the input a set of raw data that must be transmitted to the user and formats it following the requirements of the user. View manages/handles all application processes. It handles external requests and fulfills the requirements contained in these requests. After that, it gives out relevant instructions to the Model. Then, it transfers the info received from the Model to the appropriate situation for the View. This is done to represent the necessary information correctly. Controller Model-View-Presenter MVP is a design template derived from MVC that is used mainly to build a user interface. The template first appeared in IBM and then used in Taligent in the 1990s. The MVP, unlike the MVC, has a slightly different approach. MVP scheme is similarly made up of three components. The Presenter is not required to adhere to the model changes. Now the Presenter (bearer), gives the idea of ​​changes. This approach allows you to create a presentation abstraction. You can implement this template by rendering view interfaces. Each presentation will have interfaces with specific sets of methods and properties required bearer. Bearer, in turn, initialized with this interface, subscribes to the event of the performance and, if necessary, data is suppressed. Model-View-View Model MVVM is a template that has emerged to circumvent the limitations of MVC and MVP patterns and brings together some of their strengths. It is used when designing an application architecture. It was originally introduced to the community by John Gossman in 2005 as a modification of the MVP template. MVVM is focused on modern development platforms and has three main components: : just like in the classic MVC, the Model represents the basic data needed to run the application (classes, structures). Model : a graphical interface, that is, a window, buttons, etc. View is on one side an abstraction of the View and, on the other, provides a wrapper of the Model data to be linked. That is, it comprises a Model that is converted to a View, and it also contains commands that the View can use to influence the Model. ViewModel Final Word The Model-View-Controller is a classic pattern that has been successfully implemented in web development. MVP/MVVM is said to be better than MVC architecture. But first, there is a small number of sources explaining the MVP and MVVM architecture on the mobile app development. Second, there is no empirical evidence and careful analysis to support this view. Thus, developers still doubt whether it is worth moving from MVC to new architectures. Because such decisions require the refactoring of the whole scheme, which demands a lot of effort from creation to testing. Also, for those who have used MVP, reducing MVVM encoding may be appealing. However, this will also cause new problems. So, the choice of a specific pattern is up to the developer, who determines a more suitable template for each particular case.

MVC vs. MVP vs. MVVM: Which Pattern to Choose for Android App Development?

Looking for a new desktop , I want to take a look at different desktop environments. The selection is wide and choices are almost unlimited. I like to start with Xubuntu today. Xubuntu is a derivative of Ubuntu which uses Xfce instead of GNOME as its desktop. This is how Xubuntu describes itself on the : for our school computers project website Xubuntu is an elegant and easy to use operating system. It comes with Xfce, which is a stable, light and configurable desktop environment. Xubuntu is perfect for those who want the most out of their desktops, laptops and netbooks with a modern look and enough features for efficient, daily usage. It works well on older hardware too. Does Xubuntu offer what it promises? Is it the best compromise of a modern desktop with low hardware requirements? I’d like to take a closer look at that using our criteria. Stability The installation went without any problems. This is no longer a problem in most cases today 🙂 . In my tests I could not see any stability problems so far. Support In contrast to Ubuntu LTS, Xubuntu LTS offers 3 instead of 5 years of support. 5 years is certainly better, but usually we will update our image after 3 years at the latest. On the server the longer support periods are more important than on the desktop. Low Hardware Requirements The hardware requirements for Xubuntu are quite low. They recommend 1GB RAM and 20GB free hard disk space. After the start Xubuntu consumes about 500MB of RAM. But as soon as you start Firefox with a few tabs, the consumption quickly rises to over 1GB. Therefore you should have at least 2GB installed. Otherwise Xubuntu is much more frugal than Ubuntu with GNOME or Unity. Easy to use This point is rather subjective, because everyone has become accustomed to a desktop environment over the years. No matter if Windows, macOS, Unity, Gnome, Xfce, KDE — I could continue the list. For example, I’ve got very used to and get along well with it. I find it difficult to switch to GNOME or any other desktop environment. In a school there is much more “bandwidth”. I don’t think you can do so much wrong here if you use Linux in school. For most of your students and teachers, the desktop environment will be new. It is much more important to offer introductions, training and workshops to get colleagues used to a new environment. In general, you can decide whether you prefer Windows 10 or macOS “style”. Unity Xfce has a start menu and can be extended with a dock (e.g. ). This should help most people to find their way around after a while. Plank Modern & Beautiful By default, Xubuntu’s appearance is rather old-fashioned, neither pretty nor particularly modern. You can use the package manager to install additional themes that make the Xfce desktop more beautiful. One is the Arc or Numix theme. I also found the theme interesting. Qogir Conclusion Xubuntu will definitely be a candidate for our Linux desktop in school. This is mainly due to the low hardware requirements. As soon as v7 is released as beta, we will test Xubuntu in our school environment. As you know, most difficulties and stumbling blocks only appear when you actually use it. The look&feel is a little damper, even if you can make it prettier. Although the new Ubuntu theme in Ubuntu 18.10 still looks better. linuxmuster.net Originally published at openschoolsolutions.org .

Xubuntu — Best Desktop for Linux in School?

So after ten years, are ? In 2008 saw the zenith of this with regards to personal computing. The as terribly fashionable, as platform holders did their best to squeeze as much computing as they could into as small a space as possible.Their ubiquity has all but vanished, given how powerful our smartphones have become. The phone that you’re reading this on, or is possibly in your pocket, or in your bag is a portable computing powerhouse — but imagine if something were not too much bigger than that, that you could do actual computer work on. A ultra portable computer running the last version of Kali . netbooks finally cool again Netbook linux Early this year a mini-PC the size of a portable video game console that sports a quad-core Intel Z8750 CPU, 8Gb DDR3 RAM, 128Gb Samsung eMMC for storage, 7000 mAh battery that manufacturer says should be good for up to 12 hous of run time, WiFi, bluetooth, HDMI port and all the things what would you want in a laptop of this size. The little computer measures just 7.1″ x 4.2″ x 0.7″ which makes it just a little larger than a big smartphone when the lid is closed. This thing looks adorable. It has the stylized Apple-style metal case rather than the more common plastic but whether you can actually fit the GPD Pocket in your pocket depends on how big your pockets are. GamePad Digital (GPD) a technology company based in Shenzen, China. Among other products, they have created several handheld video game consoles which run Android on ARM architecture and x86 Windows. And while Pocket it is not exactly cheap it is possible to find it at the same price of the original GPD crowdfunding. bought a GPD Pocket 7 $499 As is often the case with notebooks and Linux, the support shortly after hardware launch leaves much to be desired, even when the manufacturer offers its own linux and community driven support is already included in the recent versions of the Linux Kernel. Unfortunately the latest Kali need some kernel patches and workarounds to run on GPD. What people are doing meanwhile is installing ad-hoc Ubuntu or Xubuntu images ( ) from a pendrive and then installing all the Kali tools they need via scripts like Katoolin ( ) which will effectively convert almost any debian-based distro into a (more-or-less) fully-fledged Kali platform. I previously wrote about https://github.com/LionSec/katoolin And so it was until , a well respected hacker know for Raspberry Pi pentest oriented Linux builds, took things into his hands. Re4son has released a custom Kali Linux images for the GPD Pocket, including the lastest Kali 2018.2. Re4son Pocket-Kali Now installing Kali in the GPD is just as easy as in a vanilla PC. These are the steps you should follow: Download the latest ISO image from here: https://whitedome.com.au/re4son/download/kali-pocket/ Write the image to a USB drive (DD, Rufus, Win32DiskImager, ..) Insert the stick into your GPD pocket, turn on and press F7 until boot menu pops up Select boot from USB stick In the Kali menu, select “Kali Live” and boot into desktop There are two ways to install:1. The comfortable way with proper screen orientation but no encryption support– select “Live (forensic mode)” and boot into desktop– in Kali, run the debian-installer (if you booted into normal live mode, run GParted and unmount disks first)2. The 90 degree way – use this if you want to install kali in an encrypted volume– select “Install”– tilt your head 90 degrees Now you have to choose if you prefer to delete everything and install only Kali Linux or resize Windows and have both. Reboot Enjoy The Pocket-Kali image comes with only “top10” & “wireless” set of Kali tools to keep the size down. Just run “kali-linux-full” to get the whole shebang. If you choose to install Kali alongside with Windows 10 keep in mind that it is possible that after the installation Windows option do not appear in the boot grub menu. The solution is as easy as running “grub-update” from a root console and restarting the system. After some testing of Kali-Pi current Version: 4.18-rc5-re4son+_1 i have managed to get Kali up and running on the GPD pocket and everything works fine the fan, Wake/Sleep, WiFi/Bluetooth, proper screen rotation, graphics and audio. Remember that the mini GPD does not have an Ethernet port, but that something easily solved with one . USB-C gigabit ethernet adapters Thanks to its size and Kali Linux the GPD becomes an all around device for the Pen-testing on the go. Couple it with some external devices such as high power wifi/bluetooth or SDR radio receiver to turn it into the ultimate portable wardriving machine.

Why Windows on ARM?

On the web it is common to see this kind of layout when you’re browsing a plethora of content with no discernible structure: Your eye is naturally drawn to shapes you recognize. Our visual cortex can only process so much information at one time and our pea-sized attention spans can’t keep up. Whatever is not recognized is filtered out, and while it appears in your visual field it does not imprint. It’s called a and I’m here to tell you it sucks. masonry layout But the newspaper… In the days of the early mechanical printing columns were used because type blocks had to be manually arranged and later were formed on demand. This was no easy task. As we transitioned to modern printers, columns persisted because it allows more various articles above the fold and works well with advertising. So why do we still use these layouts on the web in the year 2017? For the very same reasons: advertising and loosely related content. If you are deciding whether or not you should use a masonry layout, the answer is almost always no. There is one exception: when you can’t sort your content by order of appeal. The Devil Goes by Many Names: , , , — these are all wonderful implementations of what a masonry layout looks like. And they power many websites because of their ease of use and the features they offer. The problem however, is they aren’t built for speed and deceive the developers using them. Isotope Packery Masonry.JS Bricks.JS In 2016 I was tasked with developing an entirely new React web application for . This is how the website looked before: The Hunt There is no doubt that this grid display is dated, but it’s also really easy to navigate because it’s linear. It flows like a book, line by line. If I could go back and make a better case for that layout, I would. Because masonry layouts are slow… We started with Isotope JS. I’ve used it before in previous projects and it does alright for lighter websites and static blogs. In development I never noticed any performance issues because I running an i7 Intel 3.4GHz processor and 16GB of RAM. When we launched our users were reporting crashes and laggy scrolling. I dug into the library and found the APIs it was hitting were much slower and out of date, causing unnecessary browser repaints. The other problem was Infinite Scroll, another bad user interface pattern we can’t seem to get rid. But that’s a whole other subject. In this case, the infinite scroll and masonry layout were loading hundreds of DOM elements per page and repainting far more than necessary. What good is a masonry layout if your users can’t get past page three on their netbooks and tablets? I combed through many of the masonry layout libraries out there. Against the recommendations of just about everyone I talked to, I knew I had to do the one thing I didn’t want to do. I wrote my own layout engine… Sometimes you have to start from scratch. What we need from a masonry layout is not the same others need. Many masonry layouts have wonderful features like variable element sizing and drag-and-drop. I set out to figure out why some of these libraries were slow. What I found is that many of the features that make them flexible also hurt. For example variable sizing is a huge performance drain: measuring a hundred element size models is expensive. And in some instances a library would use methods that would cause an unnecessary repaint to get the width and height. Another issue is that all of these elements add up and as the page grows, the calculations incur exponentially. Then I looked at Pinterest — the pinnacle of masonry. I wondered how the engineers managed to keep it fast and usable. So here is where I drew the line: Predetermined element height — this made it easier to layout items at the same place every time. Without this the entire layout would need to re-calculate to accommodate a new item. Fixed column widths — percentages are expensive and along with #1 this would save us from unnecessary paints and repaints to slow DOM APIs Render only what’s visible — by reducing the number of DOM elements the browser has less objects to paint on scroll and reflow. The process involved a lot of math and patience — calculating where to place items and how to place them efficiently. For example when an item spans multiple columns it will create a gap if the items above do not align. This was the most challenging aspect because we didn’t want a fast masonry layout with empty whitespace everywhere. All of this had to fit inside a React Component and go with the grain of lifecycle events. So when infinite scroll loads a new page only new items should layout. And what a beautiful React Component it turned out to be. I decided to write this post to document both the frustration and immense pride I felt for this effort. When I reflect on the process and the result — I see some of my best work. Trying and trying, iteration after iteration; the “are we there yet” moments. The voice at the back of my head saying “don’t write a layout engine.” The Result: a fast Masonry layout built in React It turned out to be incredibly performant. On a Chromebook there were no hiccups and rendering was faster than it took for the server to return the next page. I immediately made the component available via (check it out if you want to see what’s under the hood). It’s not available as a package because it’s not “one size fits all” and the last thing the web needs is another masonry library. Github You can see this engine running live @ thehunt.com proceed with caution. There are a plethora of resources available for Flexbox, CSS4 Grids, and performant interfaces on the web. Seek out better user experiences that flow naturally. If you are looking to do it yourself then I would suggest doing your research and eliminating over-engineered features. If you are thinking of rolling your own layout engine: I hope you enjoyed reading this: if you feel the pain of masonry layouts or you’ve been there before feel free to share your experience.
