How HP left me Paranoid after taking My 3400$

Imagine your office . Cyber attackers are trying to get into it. They know that your company has lucrative proprietary data. They know that your company will be tempted to pay expensive cryptocurrency ransoms if they can cripple your computers with ransomware. Even if you keep good backups, . 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. . Start with their web form here DreamWorks Animation relies on HP Secure MPS You’ve probably heard of DreamWorks Animation. They’re known for hit films such as Shrek, How To Train Your Dragon, and Kung Fu Panda. Chances are you’ve watched at least one of their movies with your family. 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? HP MPS is a major factor.

Learn Machine Learning by building home price prediction in 15 lines of code. This blog post was originally published on HP Developers Portal ( hp.io ). is here to stay. Whether it will lead to singularity is still speculative, however, will it change the way software engineers solve problems should not be questioned. It is already being implemented by many companies to create richer UX like with Apple (cool examples at ) and answer complex questions like with Amazon Echo. Here at HP, we use it to answer complex challenges we face around to part performance optimization and to even print customized . Machine Learning is a very powerful technique that problem solvers must understand now — not next year. Machine Learning ARKit madewitharkit.com 3D printing footware Applied Machine Learning Machine Learning has a lot of moving parts. In this post, I will demystify ML by helping you write working code. And I will discuss what you can do to take the next step. First consider how software was written before the advent of Machine Learning. Software engineers gave computers step-by-step instructions to solve a specific problem. Let’s use an example from the banking industry. Say we wanted to write a program that would predict whether a loan applicant was likely to pay back their loan. We could write a program that analyzes that individual’s profile, setting parameters for key variables: Credit score Loan amount Type of loan Length of membership The programming logic would look like this: Fig 1. Simple bank loan approval programmatic logic Based on the complexity of a problem, these manual steps of tweaking parameters and writing instructions may become complex or even impossible. Imagine the complexity of coding for object recognition. Now a machine can learn to solve problems just by looking at examples. With Machine Learning, the engineer can train an ML model that learns from loan data from thousands of borrowers. The ML model can keep improving over time, responding to more data and new trends. For example, after the Equifax security breach in 2017, credit scores from Equifax may not be as valuable as scores from the other two credit reporting agencies. If this is reflected with real loan outcomes, the ML model would tweak its parameters to give less weight to Equifax credit scores. With enough data, the ML model will train itself to find optimum parameters. This technique is called . We will use it in our tutorial below. (The other popular techniques are and .) supervised learning unsupervised learning reinforcement learning Fig 2. Simple bank loan approval ML logic Home Price Prediction Tutorial The fastest way to learn about Machine Learning is to build a learning machine, so let’s build our own Home Price Predictor. Let’s say each house has a base value of $240k and each bedroom adds $15k to the price. (We use “k” to abbreviate 1,000 to keep the numbers small.) Bedrooms Home Price 0 $240k 1 $255k 2 $270k 3 $285k 4 $300k Predicting a house price requires a simple linear model (y = mx + b). We can use this formula: Price of house = ($15k * # of bedrooms) + $240k Now let’s build a Machine Learning program to do this. Using the training data, we want our model to figure out the values of and , which we know will be 15 and 240, respectively. **m** **b** We will be using python for our code. Create a new python file with the code below and name it In the code, we start by importing the library, setting up some initial variables, linear model and loss function. Consider installing and using the following Docker Command if you don’t have your environment setup. **home_price.py** . Docker docker run -it gcr.io/tensorflow/tensorflow:latest /bin/bash Yes, without the print statements and comments it is just 15 lines of code. 🙌 In the code, we are setting up some basic placeholders and variables to be used during training. Then we are writing a function, which is calculated by subtracting (the given value or ground truth) from the value. We then pass that value to our . With each iteration, our will try to get the values of and as close as possible by updating the value of the variables and . loss y prediction loss optimizer optimizer y prediction m b Next, we are training the model 1000 times with our training data. At the end you should get outputs which look like this Value of m is [ 15.00007153] and value of b is [ 239.99978638]. 💁 What do you think of the values for m and b? Very close to our expected values, right? Below is the visualization of how the model is being optimized at each iteration. In the beginning values of and are starting at (as we specified in our code), but over time they get to the right values. And we are also seeing our (prediction — y) decrease to 0 over time. m b 1.0 loss Fig 3. Values of _m_ , _b_ and _loss_ over 100 iterations. Q. How would you account for a neighborhood in your Home Price Predictor? Q. How would you take home images into consideration? Hopefully, the above tutorial helped you understand the basics of ML. Soon every full stack engineer will be using ML in their applications.

Why? For me, self-hosting is like having my own personal playground where I can experiment, tinker, and learn. It’s a great way to explore new technologies, try out different setups, and have fun with my projects. As part of my job, I need to have a deep understanding of developer experience. The best way to build this understanding is to be the developer, both initial experience with any development tool, as well as day-to-day work with these systems. Self-hosting is in a way, building empathy with the developer community. Understanding differences, and good/bad versions. My main reason is “learning.” There are a bunch of other reasons one may choose to do this: Privacy: your data
Full control: You own it (well, both good and bad)
Cost-effective: (may not be always true, but mostly true) You Shouldn’t Do This… But if You Really Want to… I don’t suggest this route for the majority of the people. It’s hard, you’ll hit walls way more frequently than you want. You have to be a warrior. If your reason is similar to mine, go for it. There is a strong determining factor though, your connectivity. Let’s get started. I’ll start the connectivity, then the hardware and software. Sounds Common but Not So Common: It’s a Privilege to Be on Fios While high-speed internet has become more commonplace, it’s still a privilege, especially in the United States. We’re (I’m) definitely taking it for granted. I use Verizon Fios is a fiber internet service. If it wasn’t for this, I wouldn’t self-host my stuff. The big practical separation for Fios is how stable it is, regardless of the “mpbs/gbps” package you have. I used Fios in residential and office setups in New York City for years. I got off as I moved to different neighborhoods, and I really really missed it when I didn’t have it, even though I got 1gbps service packages from other providers. Back in the day when we used dial-ups and tried to play Half-Life (or Counter-Strike) online, your connection speed mattered but “lag” mattered even more. I lived in Turkey back then, and we had a cable internet provider vs ADSL services the difference was that you were getting super low lag/ping in cable network even though you were 1/4, 1/3th of the connection speed you had compared to other services that bragged how fast they were. Didn’t matter when playing online. I have 300/300mbps which is what’s called a “symmetrical” connection. 300mbps is already way higher than the average internet connectivity worldwide (although certain countries/cities regions have way faster networks, overall world citizen gets access to the internet at lower speeds). But it would be ok even if it was slower because it’s a Fiber network, and it’s symmetrical which means download and upload speeds are the same. Often, you see traditional ISPs advertise something ridiculous with high speeds like 500mbps, but it’s often only referred to as download speeds. And in the majority of consumer scenarios, this is fine. But you need the upload speed to be high and consistent/stable when you want to serve upstream. Hardware Since it’s hobby purposes, I initially searched some “old” servers (like servers sitting on racks) on eBay. Then I realized it had a million combinations of hardware components, like CPU architectures, and network interfaces. I quickly went down the rabbit hole of Reddit threads both fun and scary stories. These “serious” server hardware were electric eating, heating sources that are also giant, require space kinda machines turned me off, and I backed out quickly. Then I explored mini PCs, which are more common computers that could handle my applications really easily. Think like you’re looking for a computer that you could use, but instead, you just host stuff and it sits somewhere in your home in a closet, without being a fire risk or a thing that you need to worry about how to keep it cool. I bought an “HP Elite Desk Mini” which is a decent computer if I were to use it as my desktop. It has 16GB memory, an i7 quad-core CPU, and 510 GB SSD. I think I bought it under $150 on Amazon. You can go fancier with a much beefier machine with a few hundred dollars if you’re being much more serious about this. I’m thinking of buying another (same machine) and stacking them. The footprint of this machine is super small. It snuck under my Verizon router in a closet, has almost zero noise, and barely heats. I’m sure if I find an ARM version of this thing (or a Raspberry Pi) I can go smaller and have almost no heat but I’ve never seen overheating on these. Whether this machine is a good or bad hardware decision, it’s debatable, but I’m really happy a few years in. Software: Ubuntu & Docker The first thing I did was to clean it up and install Ubuntu (LTS). Almost bare-bones Ubuntu then right away docker installed. I have Nginx and PHP on it for some early play of a WordPress blog (not this one) but then abandoned it. I run almost everything exclusively in Docker (more on this below). I try to update & upgrade Ubuntu once a year. Nothing else. Access: Cloudflare Zero Trust The machine itself is completely closed to direct internet access. Its IP Tables don’t allow connections even from the local network (except SSH port accepts local network IP range). Traditionally, the machine needs to open ports outside, then have a router port forwarding and set up all public IP sort things. More than 2 decades ago, I did that with static IP from my ISP. Man, all the hustle… None of that is necessary anymore. I use Cloudflare Access and Tunnels which has an agent always running in the server, and from remote configuration, I can listen to any internal port (without opening it up) and forward the port directly to a subdomain of my domains. This shortcut the DNS works for me too. On top of that, most of my private apps run on subdomains that are protected by Cloudflare Zero Trust access (only me). I love Cloudflare’s feature that solves 2 to 3 problems at once. One might wonder, what happens if Cloudflare has an outage, and their Zero Trust tools stop working, does it open my apps to the public all of a sudden? No, because my apps are not open to the public in the first place. Zero Trust tunnel has to work in order to open it up to the public, and if Zero Trust authentication is down, the subdomain will also not be accessible (because it’s proxied through Zero Trust “application” record. Worst case scenario, I lose access to my private apps from outside. Even with that, I can SSH to my server and create a tunnel, port forwarding to the specific port the app is running. On a normal day, I simply join to Zero Trust network using Cloudflare’s desktop app WARP, which replaces VPN for me. All things considered, I’m sure there are still holes and paranoia in this plan. You can go through a more traditional route that is not any different than hosting this instance in Digital Ocean or AWS and replicate what you think is “more secure”, but I’m pretty happy with the baseline Cloudflare brings, and solves a few unnecessary things I have to take care (like no need to do reverse proxy for all apps I’m running). Deploy Apps: Portainer + Gitops I use Portainer to both set up deployments and manage my containers. Portainer is essentially a nice UI version of your docker command line tools. But where it shines is the gitops integration that integrates with GitHub via webhooks, so when I push any change to any of my app repos (which all have docker-compose.yml that includes their infra and application configurations), my apps get re-deployed by portainer. This makes spinning up a new app, or an open-source tool in my server, a breeze. I covered Portainer and its gitops integration in this article: Portainer + gitops ❤️: A simple way to deploy and manage your self-hosted applications Why? For me, self-hosting is like having my own personal playground where I can experiment, tinker, and learn. It’s a great way to explore new technologies, try out different setups, and have fun with my projects. As part of my job, I need to have a deep understanding of developer experience. The best way to build this understanding is to be the developer, both initial experience with any development tool, as well as day-to-day work with these systems. Self-hosting is in a way, building empathy with the developer community. Understanding differences, and good/bad versions. My main reason is “learning.” There are a bunch of other reasons one may choose to do this: Privacy: your data Full control: You own it (well, both good and bad) Cost-effective: (may not be always true, but mostly true) Privacy : your data Privacy Full control : You own it (well, both good and bad) Full control Cost-effective : (may not be always true, but mostly true) Cost-effective You Shouldn’t Do This… But if You Really Want to… I don’t suggest this route for the majority of the people. It’s hard, you’ll hit walls way more frequently than you want. You have to be a warrior. If your reason is similar to mine, go for it. There is a strong determining factor though, your connectivity. Let’s get started. I’ll start the connectivity, then the hardware and software. Sounds Common but Not So Common: It’s a Privilege to Be on Fios While high-speed internet has become more commonplace, it’s still a privilege, especially in the United States. We’re (I’m) definitely taking it for granted. I use Verizon Fios is a fiber internet service. If it wasn’t for this, I wouldn’t self-host my stuff. The big practical separation for Fios is how stable it is, regardless of the “mpbs/gbps” package you have. I used Fios in residential and office setups in New York City for years. I got off as I moved to different neighborhoods, and I really really missed it when I didn’t have it, even though I got 1gbps service packages from other providers. Back in the day when we used dial-ups and tried to play Half-Life (or Counter-Strike) online, your connection speed mattered but “lag” mattered even more. I lived in Turkey back then, and we had a cable internet provider vs ADSL services the difference was that you were getting super low lag/ping in cable network even though you were 1/4, 1/3th of the connection speed you had compared to other services that bragged how fast they were. Didn’t matter when playing online. I have 300/300mbps which is what’s called a “symmetrical” connection. 300mbps is already way higher than the average internet connectivity worldwide (although certain countries/cities regions have way faster networks, overall world citizen gets access to the internet at lower speeds). But it would be ok even if it was slower because it’s a Fiber network, and it’s symmetrical which means download and upload speeds are the same. Often, you see traditional ISPs advertise something ridiculous with high speeds like 500mbps, but it’s often only referred to as download speeds. And in the majority of consumer scenarios, this is fine. But you need the upload speed to be high and consistent/stable when you want to serve upstream. Hardware Since it’s hobby purposes, I initially searched some “old” servers (like servers sitting on racks) on eBay. Then I realized it had a million combinations of hardware components, like CPU architectures, and network interfaces. I quickly went down the rabbit hole of Reddit threads both fun and scary stories. These “serious” server hardware were electric eating, heating sources that are also giant, require space kinda machines turned me off, and I backed out quickly. Then I explored mini PCs, which are more common computers that could handle my applications really easily. Think like you’re looking for a computer that you could use, but instead, you just host stuff and it sits somewhere in your home in a closet, without being a fire risk or a thing that you need to worry about how to keep it cool. I bought an “HP Elite Desk Mini” which is a decent computer if I were to use it as my desktop. It has 16GB memory, an i7 quad-core CPU, and 510 GB SSD. I think I bought it under $150 on Amazon. You can go fancier with a much beefier machine with a few hundred dollars if you’re being much more serious about this. I’m thinking of buying another (same machine) and stacking them. The footprint of this machine is super small. It snuck under my Verizon router in a closet, has almost zero noise, and barely heats. I’m sure if I find an ARM version of this thing (or a Raspberry Pi) I can go smaller and have almost no heat but I’ve never seen overheating on these. Whether this machine is a good or bad hardware decision, it’s debatable, but I’m really happy a few years in. Software: Ubuntu & Docker The first thing I did was to clean it up and install Ubuntu (LTS). Almost bare-bones Ubuntu then right away docker installed. I have Nginx and PHP on it for some early play of a WordPress blog (not this one) but then abandoned it. I run almost everything exclusively in Docker (more on this below). I try to update & upgrade Ubuntu once a year. Nothing else. Access: Cloudflare Zero Trust The machine itself is completely closed to direct internet access. Its IP Tables don’t allow connections even from the local network (except SSH port accepts local network IP range). Traditionally, the machine needs to open ports outside, then have a router port forwarding and set up all public IP sort things. More than 2 decades ago, I did that with static IP from my ISP. Man, all the hustle… None of that is necessary anymore. I use Cloudflare Access and Tunnels which has an agent always running in the server, and from remote configuration, I can listen to any internal port (without opening it up) and forward the port directly to a subdomain of my domains. This shortcut the DNS works for me too. On top of that, most of my private apps run on subdomains that are protected by Cloudflare Zero Trust access (only me). I love Cloudflare’s feature that solves 2 to 3 problems at once. One might wonder, what happens if Cloudflare has an outage, and their Zero Trust tools stop working, does it open my apps to the public all of a sudden? No, because my apps are not open to the public in the first place. Zero Trust tunnel has to work in order to open it up to the public, and if Zero Trust authentication is down, the subdomain will also not be accessible (because it’s proxied through Zero Trust “application” record. Worst case scenario, I lose access to my private apps from outside. Even with that, I can SSH to my server and create a tunnel, port forwarding to the specific port the app is running. On a normal day, I simply join to Zero Trust network using Cloudflare’s desktop app WARP, which replaces VPN for me. All things considered, I’m sure there are still holes and paranoia in this plan. You can go through a more traditional route that is not any different than hosting this instance in Digital Ocean or AWS and replicate what you think is “more secure”, but I’m pretty happy with the baseline Cloudflare brings, and solves a few unnecessary things I have to take care (like no need to do reverse proxy for all apps I’m running). Deploy Apps: Portainer + Gitops I use Portainer to both set up deployments and manage my containers. Portainer is essentially a nice UI version of your docker command line tools. But where it shines is the gitops integration that integrates with GitHub via webhooks, so when I push any change to any of my app repos (which all have docker-compose.yml that includes their infra and application configurations), my apps get re-deployed by portainer. This makes spinning up a new app, or an open-source tool in my server, a breeze.

What is HPC? High-Performance Computing (HPC) refers to the practice of aggregating computing power in a way that delivers much greater power than traditional computers and servers. HPC, or supercomputing, is like everyday computing, only more powerful. It is a way of processing large volumes of data at very high speeds using multiple computers and storage devices as a cohesive structure. HPC makes it possible to explore and find answers to some of the world's biggest problems in science, engineering, and business. An interesting example: Imagine that Volkswagen wants to test the resistance of a new car model before launching it on the market. Instead of spending enormous resources building and physically testing multiple prototypes of the car, they can use high-performance computing to perform detailed simulations. Volkswagen has a large data center with high-performance computers to run detailed simulations of the car's behavior in a variety of scenarios. Each simulation is like a virtual test, where different aspects of the vehicle are digitally evaluated. For example, engineers can simulate how the car behaves in different road conditions, such as sharp curves, wet roads, or even extreme collision situations without needing to test this in a physical car. HPC and the Future of the Technology Market With the advent of the massive use of artificial intelligence at a business and personal level, HPC has become indispensable, and I believe that the trend will be to have these technologies increasingly integrated into our daily lives. HPC plays a fundamental role in the construction of large models used in the area of ​​artificial intelligence. AI algorithms, such as deep neural networks and machine learning algorithms, often require enormous amounts of computing power to train and run complex models on large data sets. In this sense, HPC provides the processing power necessary to handle these computationally intensive tasks efficiently. In the HPC area, we can see an interesting view of where the personal hardware market is heading: In HPC, accelerators such as GPUs and FPGAs are widely used to increase computational performance. These accelerators are becoming more common in personal devices, especially in smartphones and laptops to handle demanding graphics tasks, games, and AI applications. In the future, we can expect wider integration of specialized accelerators into hardware for personal use. Where to Start? Well, despite being a completely new area for some, it's not that complicated. In fact, there are few materials available in our language on the subject, but there are two with subtitles that provide a fairly good introduction to this world, and I will leave them in the reference links below! The important thing is to understand that despite being something we are not used to in our daily lives, it is still a computer. Some technologies are more present in this area such as C, C++, Python, and R. And some libraries and APIs such as CUDA, OPenMP, and others. The way of writing code is a little different, but it is still code. A great way to start is by looking at languages ​​that offer options for parallelism.

A Gentle Introduction to HPC - High Performance Computing

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! As we approach the listing date on the 24th of August, we will reveal more details about our partnerships with top-tier centralized exchanges. as we harness the best of tech to shape a future brimming with possibilities.

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
