Solidus AI Tech is on a mission. A mission to simplify access to cutting-edge technologies like Artificial Intelligence-as-a-Service (AIaaS), Blockchain-as-a-Service (BaaS), and High-Performance Computing Power (HPC). Every service and technological feature on our platform harnesses the potential of our native token, AITECH. Our commitment to the environment led us to design an 8,000 sq.ft. high-performance computing data center, positioned in a secure European location. But that's not all. The AITECH token, the world’s first deflationary AI infrastructure token, stands as the cornerstone of our services. This token serves as a payment gateway for licensing AIaaS, BaaS, and renting HPC through our Infrastructure-as-a-Service (IaaS) platform. Soon, Solidus will introduce a marketplace where software developers can launch and monetize their AI applications. Thanks to our profit-sharing model, developers stand to gain significantly. AITECH, the driving force behind the Solidus ecosystem, can be used to acquire any item on our platform. We've simplified transactions by enabling seamless conversion from fiat to AITECH. Worried about conventional payment methods? Solidus has you covered. As a testimony to our commitment to transparency and innovation, 5%-10% of AITECH tokens used on the platform are automatically burned. This deflationary measure is updated in real-time on our dashboard. Addressing Europe's HPC Deficit Europe's High-Performance Computing scene is, unfortunately, lagging. With none in the global top 10, European enterprises often look overseas to satisfy their HPC needs. This brings a slew of issues ranging from security concerns to latency. When EU consumes a whopping third of the global HPC resources but produces a mere 5% of the computing power, the disparity is palpable. Dependence on costlier U.S. facilities exacerbates this problem. Solidus AI Tech aims to change this narrative. Located in Bucharest, our center is set to bridge this divide, allowing European businesses to tap into supercomputing power without crossing borders. Blessed with inexpensive electricity, blazing-fast internet, and rigorous IP protection, Bucharest offers us a competitive edge. Our efficiency levels are expected to surpass industry standards, consuming around 40% less power. As we expand, we aspire to redefine the European HPC scene and to earn a spot among the global top 10. Exciting Launchpads & Listings on the Horizon Mark your calendars! AITECH's upcoming launchpads are scheduled for: 18th August with TRUSTSWAP 21st August with CHAIN GPT PAD and ENJINSTARTER 22nd August with SEEDIFY and DECUBATE. Stay tuned!

We at have been using HP Common Slot power supplies from 460W to 1400W for years. They are efficient, reliable and easy to integrate with servers from different manufacturers. If you have a bunch of old server cases piled up, use them to save about €500 to €600 on new systems. HOSTKEY Standard Common Slot power supplies first appeared around 2010 in the Proliant G6 and most other HP servers at the time. These mass-produced devices are extremely inexpensive on eBay/AliExpress (€20 to €50 each). As a rule, the power supply units are operational: cases of failure when switching them on are extremely rare. There are no problems with bulk shipments either: we buy more than 100 at a time. Common Slot power supplies are quiet: at low and medium load their noise is lost behind the noise of a normal computer. At full load, the small fan makes a characteristic loud squealing noise of 65 dB (however, it is not audible in a data center). The HP site contains little information on the specifications: there is no diagram or pinout available, but there is a suspiciously similar Murata Power Solution device from another vendor. On their website, we found the we needed, including detailed manuals for and power supplies. There are also some available on the web, so HP Common Slot seems to be more than just our cup of tea. documentation 460W 1600W research results from enthusiasts What do the hackers say? The efficiency of the HP Common Slot at medium load is 92 - 94%. To turn it on, connect pins 36 (Power Supply Present Signal - short pin) and 37 (12V Standby Output) on the bus through a resistor of about 22 kohms to make the PSU think it is inserted in the slot, and connect pin 33 (Power Supply on/off control signal - far right) to the ground wire. Up to eight HP Common Slots can operate in parallel. No extra steps are required to run the PSU in parallel with the load: just run the main load and the Vsb lines separately (see table in Murata Power Solution documentation). The PSU has an I2C interface and an analog power indication output (60.15 mV/A). How to use it The easiest option is to buy a ready-made distribution board like this on AliExpress or another online store: Or a slightly different one: Note that the first board has a power button - it would be inconvenient to remove it from the server enclosure. The second board has a switch that you can turn on and leave alone. The price of the item is . about €9 If you don't like ready-made boards, you can make your own. You will need a Wingtat model . The company responds quickly to inquiries and ships orders for 50+ connectors for about $2 apiece. They are available at retail on AliExpress. If you intend to use a full 1200W power supply, it is best to order the board with thicker copper. The connector on it should be soldered with a hair dryer and a thin solder with flux: this is the fastest way to do it; a regular soldering iron does not work well on such boards. 2.54 EDGE SLOT DIP 180° SINGLE LEAF TYPE WITHOUT EAR High Power S-64M-2.54-5 slots We use boards of this design: The schematic is available in our on GitHub. At connector J1 you can measure the voltage and understand the current load on the power supply - 60.15 mV for every amp of power on the 12V bus. repository A finished example: What does it look like in a server? We often use universal Supermicro enclosures and many of them no longer have the original power supplies, which have been discontinued or upgraded for new motherboards. Looking for native PSUs is impractical because they are expensive and just as worn out. In this case, the native PSU had fallen into disrepair and was replaced with a universal 750W HP Common Slot. We cut off the excess and attached the unit to the case with double-sided adhesive tape. To convert 12V to the required ATX24 voltage we used native or their . The server in the photo is a Supermicro H11DSi with two AMD Epyc processors and about 400W power consumption. It absolutely refused to work with Chinese analogs, and the native PicoPSU didn't fit to the height and was plugged in via an adapter. The power is connected directly to the processors; it doesn't interfere with anything. PicoPSUs Chinese analogs Back view. The power supply doesn't fit very well, but it doesn't affect speed and usability. Why is this necessary? We save about €500 to €600 on new systems. This allows us to keep the cost of renting dedicated servers at market level, plus we don't throw away old cases with all the fans and backplanes, so as not to unnecessarily pollute the environment. Regarding reliability: The power supply usually fails the first time you turn it on. We have a special test rig with a category A 5A circuit breaker for this purpose. If the power supply turns on, it will continue to work for years. PSUs of this type in our data center with several thousand machines break down about once every six months, usually when upgrading the equipment. PicoPSUs in regular servers hardly ever fail. Let's try using power supplies in pairs and build a test rig for this on our server. Here the two power supplies with our adapter boards are connected in parallel. The boards are connected to each other with straight GPU extension cables. A pair of cables of 3 wires each provide a jumper for just 400 watts (at the limit). It is important that the connecting cables are of good quality: of the right cross-section and well crimped (we have just such cables). For greater reliability, 400W requires three cables with 3 wires each. The processors are each plugged into their own power supply. Does this really work? to be sure. We run Linpack on the server with both power supplies connected and take turns disconnecting them under load, then reconnecting them after a while. We ensure the voltage remains normal and the server does not reboot under stress test. The load according to the server is about 400W under stress test on the processors, so about 500W is flowing through the circuit. Check this video As you can see, the setup works: The cables and connectors do not heat up, and everything works as it should and without the server's native power supplies. Since the HP Common Slots are designed to work in pairs, they have all the necessary safeguards. Why use two PSUs? Many people think that redundancy is needed for fault tolerance: if one power supply breaks down while operating a server in a data center, the second one will keep it running. This opinion is partly correct, but there are other nuances. Often, when a power supply fails, a circuit breaker in the PDU or in the breaker box blows out (by short circuit or overload). If both units are plugged into the same PDU, redundancy will not help. Data centers are usually set up so that there are two non-overlapping power lines coming into the rack. They have different distribution cabinets, they go to different UPSs, and those UPSs are connected to different transformers and generators. This all gets switched with some delay, and the data center ensures that the power is always on one of the lines, but not both at the same time. It is essential that the server have two power supplies, or you must use a rack ATS, a fairly expensive device with a solid-state relay that can quickly and seamlessly switch between asynchronous phase inputs. Bottom line If you have empty server cases lying around, don't rush to throw them away: old hardware is not difficult to restore. The solution described in this article will allow you to organize a setup with a guaranteed or redundant power supply quickly and without significant costs. The HP Common Slot at HOSTKEY powers , modular , and . This approach allows us to combine reliability of operation, ease of assembly and maintenance, and of course, our main goal: low prices for our customers. dedicated GPU servers systems with ITX boards general purpose servers

Reanimating Old Server Cases with HP Common Slot Power Supplies

The WPS pin of the printer is required for establishing a link between your HP printer and a computer. So, if you're having trouble finding the WPS pin on your HP printer, we'll show you how to do it. But before we get into locating the WPS pin, let's find out what a WPS pin is. What is a WPS Pin? A WPS pin, or , is an 8 digit combination of numbers and/or letters used by your wireless router (Wi-Fi) to encrypt and protect your home network. It's like a password that can be found in the back or bottom of all routers. Wi-Fi Protected Setup Pin Types of WPS Connection for HP Printer There are several WPS connection types that can be used to connect your computer or laptop to your printer. The 2 most common WPS connections are: WPS Pin WPS Push Button Where is the WPS Pin on my Printer? The WPS pin for your wireless connection with your device is generally generated on the top of every modern version of HP printers, such as HP LaserJet, HP Envy 4520, and HP Officejet 4650. The printer generates a new WPS pin each time you wish to connect your printer to a device. Some HP printers, such as the HP DeskJet 2652 and HP DeskJet 2600, do not have a screen, which may cause problems for some users in obtaining the WPS pin code. However, you'll learn how to easily get your WPS code after reading this post. Where is the WPS button on my router? The WPS button is usually located on the back of your wireless router. Make sure to press it for at least 10 seconds, or until you hear a beep. You should also try pressing it multiple times in case the first time doesn't work. Connect HP printer with WPS Pin If your HP printer has a display, connecting it to your computer or another gadget is simple. Locate the WPS pin code for your HP printer by performing the following procedures. Turn on your printer From the "Control Panel" press the "Wireless button" You will see a blue light start blinking Next navigate to the "Wi-Fi protected setup" option Select "WPS Pin" option On printer screen you will see a 8 digits generated code that is a WPS pin Enter your generated WPS pin code to your computer screen to pair both of your device Connect HP printer with WPS Push button Use this approach to link your HP printer to your computer if you don't have a screen or control panel on it. Turn on your printer Make sure your printer and router are close enough to make a connection Press the "Wireless button" on your printer After the above step you will see a light start flashing Now press and hold the "WPS button" on your router for 2-3 seconds You will see WPS light start blinking on your router After sometime both the light on your printer and router stop blinking It indicates that the connection is successful FAQs How to Disable WPS? It is important to note that some router models have an option to disable the WPS. For example, the Asus RT-N66U wireless router has a "Disable Wi-Fi Protected Setup" option for this purpose. Here's how you can navigate to it: Click on "Wireless," and then choose "WPS Settings" There are three options in this tab. You have the option to press the WPS push button on your router, enter the PIN directly into your wireless device, or disable WPS entirely. Select "Disable Wi-Fi Protected Setup." This will ensure that your network is not vulnerable to security threats. How does WPS work? The following is the technical explanation of the process: How WPS works - WPS uses a special type of algorithm which makes it easy for devices to establish secure connections. After pressing the "WPS push button" on your wireless router, you have approximately two minutes to press "WPS button" on your printer. The wireless device will send a random number to the router. The router will use this random number to encrypt subsequent data communications between devices. How many digits are in the WPS Pin code? The WPS PIN code always has 8 digits. The first two digits represent the manufacturer of your device, followed by six numbers which are assigned randomly. Why is my WPS Button flashing orange? Your WPS button is not correctly linked to your router. When the WPS button lights up orange, this means that no network connection is established between your devices. In order to establish a successful connection between your WPS buttons, follow the above-mentioned steps again. Do all wifi routers have WPS? No, not all routers have WPS buttons. Some wireless devices like the Linksys E series don't come with WPS switches, but their software can be configured to do the same thing as WPS buttons. Is WPS safe? WPS is not safe. A WPS-connected device has zero security. Anyone with WPS capability can communicate to your WPS unprotected wireless networks. Though WPS claims that it makes the network secure, WPS actually does the exact opposite of what it claims by sacrificing network security in order to make connecting devices easier. Where is the WPS button on my Phone? Most WPS enabled smartphones have the WPS button either on the front or back, depending upon how it's designed. Some WPS buttons are at the top of the phone while others are placed at the bottom. You need to look for a WPS sign on your smartphone to find out where exactly is its WPS button. Conclusion Now you're able to connect your HP printer to your PC with the help of WPS pin and WPS push button. If this tutorial has helped you, share it with your friends on social media.

The Internet of Things (IoT) is forecasted to experience exponential growth. It is predicted that the global number of internet connected devices could pass 50 billion by the year 2020, and McKinsey Global Institute predicts that : ¹ ² If policy makers and businesses get it right, linking the physical and digital worlds could generate up to $11.1 trillion a year in economic value by 2025. Whilst progress is being made and IoT devices are now a regular feature in our lives, there are some stumbling blocks around cost, data and security that are preventing the rapid adoption of IoT. the current centralised nature of IoT infrastructure creates huge barriers for interoperability and interconnection of devices, massively driving up the cost of devices and IT infrastructure required. Cost: traditional IoT infrastructure is typically built with specific application scenarios in mind and this results in isolated pools of data, making it hard to fully utilise the value of IoT data. Data: cyber attacks and the theft are very real daily threats with regular instances of breaches to IoT systems. This highlights that privacy and security are critical issues that need addressing. Security: Due to it’s distributed / decentralised framework, blockchain technology has the potential to significantly reduce the cost of equipment interconnection, create new business models to maximise the value of data whilst also ensuring privacy and security. Introducing CPChain, the killer tech that the IoT industry has been waiting for Utilising blockchain as the backbone for IoT is a clear use case. Speed, scale, reduced transaction costs and security are some of the hallmarks of the blockchain promise. However, to deliver on their promise the technology needs to overcome scalability challenges around the high cost of data storage and computations and the low efficiency of current consensus mechanisms. An exciting new player has entered the market claiming they can do just that. CPChain is a China based blockchain business that attacks the aforementioned challenges, with a unique blockchain that can reduce connectivity costs, protect data and maximise the value of IoT data.

About a month ago, we released our FREE . If you’ve never used Stack before, you should totally check out that course! This article will give you a sneak peak at some of the content in the course. Stack mini-course But if you’re already familiar with the basics of Stack and don’t think you need the course, don’t worry! In this article we’ll be going through another cool tool to streamline your workflow! Most any Haskell project you create will use Cabal under the hood. Cabal performs several important tasks for you. It downloads dependencies for you and locates the code you wrote within the file system. It also links all your code so GHC can compile it. In order for Cabal to do this, you need to create a file describing all these things. It needs to know for instance what libraries each section of your code depends on. You'll also have to specify where the source directories are on your file system. .cabal The organization of a file is a little confusing at times. The syntax can be quite verbose. We can make our lives simpler though if we use the "Hpack" tool. Hpack allows you to specify your project organization in a more concise format. Once you’ve specified everything in Hpack’s format, you can generate the file with a single command. .cabal .cabal Using Hpack The first step to using hpack if of course to download it. This is simple, as you long as you have installed Stack on your system. Use the command: stack install hpack This will install Hpack system wide so you can use it in all your projects. The next step is to specify your code’s organization in a file called . Here’s a simple example: package.yaml name: HpackExampleProject

version: 0.1.0.0

ghc-options: -Wall

dependencies:  - base

library:  source-dirs: src/

executables:  HpackExampleProject-exe:    main: Main.hs    source-dirs: app/    dependencies:      HpackExampleProject

tests:  HpackExampleProject-test:    main: Spec.hs    source-dirs: test/     dependencies:      HpackExampleProject This example will generate a very simple cabal file. It’ll look a lot like the default template of running . There are a few basic fields, like the name, version and compiler options for our project. We can specify details about our code library, executables, and any test suites we have, just as we can in a file. Each of these components can have their own dependencies. We can also specify global dependencies. stack new HpackExampleProject .cabal Once we have created this file, all we need to do is run the command from the directory containing this file. This will generate our file: hpack .cabal >> hpackgenerated HpackExampleProject.cabal What problems does Hpack solve? One big problem hpack solves is module inference. Your file should specify all Haskell modules which are part of your library. You'll always have two groups: “exposed” modules and “other” modules. It can be quite annoying to list every one of these modules, and the list can get quite long as your library gets bigger! Worse, you'll sometimes get confusing errors when you create a new module but forget to add it to the .cabal file. With Hpack, you don't need to remember to add most new files! It looks at your file system and determines what modules are present for you. Suppose you have organized your files like so in your source directory: .cabal src/Lib.hssrc/API.hssrc/Internal/Helper.hssrc/Internal/Types.hs Using the normal . approach, you would need to list these modules by hand. But without listing anything in the package.yaml file, you’ll get all your modules listed in the .cabal file: cabal exposed-modules:  API  Internal.Helper  Internal.Types  Lib Now, you might not want all your modules exposed. You can make a simple modification to the package file: library:  source-dirs: src/  exposed-modules:    - API    - Lib And hpack will correct the file. .cabal exposed-modules:  API  Libother-modules:  Internal.Helper  Internal.Types From this point, Hpack will infer all new Haskell modules as “other” modules. You’ll only need to list “exposed” modules in package.yaml. There’s only one thing to remember! You need to run each time you add new modules, or else Cabal will not know where your code is. This is still much easier than modifying the file each time. The file itself will still contain a long list of module names. But most of them won’t be present in the file, which is your main point of interaction. hpack .cabal .cabal package.yaml Another big benefit of using hpack is global dependencies. Notice in the example how we have a “dependencies” field above all the other sections. This means our library, executables, and test-suites will all get base as a dependency for free. Without hpack, we would need to specify base as a dependency in each individual section. There is also plenty of other syntactic sugar available with hpack. One simple example is the github specification. You can put the following single line in your package file: github: username/reponame And you’ll get the following lines for free in your file. .cabal homepage:          https://github.com/username/reponame#readmebug-reports:       https://github.com/username/reponame/issues Summary Once you move beyond toy projects, maintenance of your package will be non-trivial. If you use hpack, you’ll have an easier time organizing your first big project. The syntax is cleaner. The organization is more intuitive. Finally, you will save yourself the stress of performing many repetitive tasks. Constant edits to the file will interrupt your flow and build process. So avoiding them should make you a lot more productive. .cabal Now if you haven’t used Stack or Cabal at all before, there was a lot to grasp here.

Maybe the cyber attackers want money? Maybe they just want to vandalize your web servers “for the lulz?” Maybe an individual attacker won’t target your company, but profitable cyber attack botnets and services can be hired so easily from the Dark Web these days. Bots will travel all over the internet looking for vulnerable targets to hit. Your office network may be tagged “it.” network it might not be practical to restore from them Can you imagine what your attack vector will be? It could quite possibly be a client PC. An employee could open a malicious email attachment that isn’t detected by your antivirus software. Maybe a cyber attack will slip through a firewall. Unfortunately, that happens sometimes. Maybe your web application will get SQL injected. Maybe an LDAP vulnerability will be exploited, and there’ll be a privilege escalation attack to your Active Directory. Did you think about that big network printer that’s sitting in the corner of the room? Print jobs are sent to it from your client PCs constantly. It’s also connected to your corporate WLAN. It to be connected to your corporate WLAN. Well your WLAN connects to the internet, doesn’t it? It’s probably connected to your private internal network too. So it’s a cyber attack vector from the public internet to your private network. Hmmmm… needs Hacking unsecured printers is easy. Unfortunately, ! 43% of surveyed companies ignore printers in their endpoint security approach. Well, what adminstrators don’t know hurt them. Corporations invest in securing their computing devices. Why not printers? according to a Spiceworks survey only 16% of IT industry respondents think printers are at high risk of a security breach will Print security has three major facets. It requires securely designed and deployed hardware, software, and networking. That means choosing to secure your office’s network requires starting with print devices which are designed with in mind from the ground up. One print device vendor knows you must secure the device, secure the data, secure the document. I got to see firsthand, that vendor is HP. cybersecurity HP has the world’s most secure print devices Image is courtesy of HP. I got an exclusive look at HP’s print security initiatives in early February. HP indeed has the world’s most secure print devices! But don’t take my word for it. Check out what it says in : IDC MarketScape: Worldwide Security Solutions and Services Hardcopy 2017 Vendor Assessment “HP Inc. is leading the charge among all hardcopy vendors around raising awareness and visibility for print and document security concerns and promotes itself as having the most secure printers in the world. HP Inc.’s approach to security takes the entire print and document infrastructure into account, beginning with locking down the device and extending into all aspects of device usage and content protection. HP Inc.’s expansive suite of print and document security solutions is based on a mix of owned technology and partner-delivered capabilities that deliver security in four primary areas: HP JetAdvantage Security Manager, HP Inc.’s pull printing solutions, HP Inc.’s data protection, and HP Inc.’s security services. HP JetAdvantage Security Manager enables customers to develop a comprehensive print security policy, assess and remediate devices against that policy, and provide audit and reporting measures based on predefined guidelines. HP Inc. offers a broad range of pull printing solutions designed to meet the needs of specific customer environments as well as data protection solutions to help organizations detect and prevent data loss through print devices. Leveraging its broad solutions portfolio, HP Inc. offers an extensive set of security-based services including Security Audit Advisory Services, Implementation Service, and Advisory Retainer Service. HP Inc. offers its security services as standalone programs, but its entire portfolio of security solutions and services are also available through HP Inc.’s Managed Print Services (MPS) offerings. HP Inc. has established a formidable managed print services practice that includes security as a backbone and is foundationally built on investments it has made in its ‘as a service’ global infrastructure. In fact, HP Inc. markets its MPS programs as ‘Secure MPS,’ part of which is simply marketing, but it also points to core capabilities that have become standard security components in HP Inc.’s MPS arsenal.” . According to IDC MarketScape’s 2017 Vendor Assessment, HP leads the industry in print security You should also consider : Quocirca’s research findings in their 2016 Managed Print Services Landscape “HP’s security offerings are a key differentiator in the MPS market which led itto launch a security-led MPS programme in 2016: HP Secure MPS. The major components of HP Secure MPS include HP’s enterprise printer portfolio, security software solutions and security services. The unique features of HP enterprise printers include run time intrusion detection, which makes HP the only printer manufacturer to offer integration of printer event data with major security monitoring and incident detection tools such as HPE ArcSight or Splunk. Solutions are a major strength for HP through its expanding JetAdvantage portfolio. It estimates that over 75% of its enterprise-direct engagements are software enabled, including solutions such as document capture, security, mobility, job accounting, forms automation and production printing. HP continues to deepen its industry focus, through market development, industry segment marketing and sales enablement capabilities. It has a range of solutions targeted at industries such as financial services, healthcare, manufacturing, communications/media/entertainment and public sector and a broad set of vertical solutions through the HP Enterprise Content Management platform.” Only HP offers a combination of security features that can monitor to detect and automatically stop an attack, then self-validate software integrity in a reboot. Inside HP’s proprietary print security features Image is courtesy of HP. Here’s a list of printer security features that are exclusive or nearly exclusive to HP enterprise print devices: Run-time intrusion detection with self-healing “Instant On” security Secure boot with self-healing Only HP and Lexmark have device level SIEM integration Only HP, Lexmark, and Kyocera have Turn On/Off Remote Firmware Upgrade Only HP and Xerox have full print device security administrator notification capabilities Only HP and Kyocera have US NIST Checklist Inclusion HP Sure Start is built into the BIOS. The BIOS runs its own firmware which checks the health and operation of your print device when you boot it up, the same way BIOS in PCs and servers works before the operating system is launched. BIOS firmware is a key target for cyber attackers, especially through malware! HP Sure Start is designed to protect your printer BIOS from being hacked. With HP Sure Start, if tampered BIOS firmware is detected, the device restarts using a safe “golden copy” of its BIOS. Your network probably runs intrusion detection devices. If it doesn’t, it really ought to! It helps to have a dedicated IDS device in your network. It’s even better to also have intrusion detection built right into your enterprise print devices. HP’s run-time intrusion detection operates constantly. It detects anomalies during complex firmware and memory operations, automatically stops intrusions, and reboots. A lot of the most destructive malware out there “calls home” to cyber attacking command and control servers. Malicious data doesn’t only enter private networks, it exits private networks too! That’s where HP Connection Inspector comes in. HP Connection Inspector evalutes connections coming into and exiting your print devices. If anything looks suspicious, HP Connection Inspector stops it in its tracks. That makes it extra challenging for cyber attackers to acquite access to your network’s sensitive data! HP Security Advisory Services Image is courtesy of HP. HP’s unique enterprise print device security strategy doesn’t stop at designing more secure hardware and software. If your network has HP devices, you can request an HP Security Manager Quick Assess. HP Security Manager Quick Assess will evaluate up to twenty of your HP network printers and will send you a full, detailed report with information about how you can improve your security. .

They’re working on new feature film animation projects right now that’ll show in your local movie theatre in the years to come. HP print devices are integral to their work. Aspects of their intellectual property work go through HP print devices and they don’t want the general public to see them until they’re ready to promote their upcoming movies. But paparazzi and entertainment magazines and websites will pay top dollar for Hollywood leaks. Pop stars and famous rappers hate it when the public gets to hear their music before they’re ready to release it. Why haven’t you seen any unauthorized leaks from DreamWorks?
