Budget (including currency): $2.300 USD (~2.000.000 CLP) Country: Chile Workloads that it will be used for: Storage Server, not too much load overall. PC, science computing with main focus on memory (need 128GB). Other details: READ DETAILS PLEASE I'm in a kind of tough spot. I have been asked to select components for two different machines on limited budget. Firstly, both machines will be installed on a medium wall mounted rack, so I guess I will have 6 Units free, this is not that important though. Storage Server: I'am not considering the drives on the budget. I need a rack (as small as possible) with around 20 slots for 3.5 inch HDDs (definitely more than 12 slots). This server won't be loaded with a lot of people downloading and loading info here, so it does not have to be that powerful. I think here is where I can go somewhat cheap. What I am concerned about is the connectivity though, is there a way to maybe run this as a server, and at the same time have 10 Gig connection to PC on the same rack? The budget for Storage Server considers: CPU CPU Cooler RAM Boot Drive Motherboard Rack Storage Chassis (>12 slots) PC: Mainly due to hardware disposal, and Chile's prices there is not a way to get workbench (EPYC, Threadripper, etc.) hardware for this. So I am aiming to consumer hardware. The only thing that I need no matter what is 128 GB of RAM and more than 6 cores (8 would be nice). I think it would be nice to have 10 Gig interface between this PC and the Storage server, but I don't know if it's possible. I don't need that much GPU power, so is not considered on the budget. For storage of this machine, it would be nice to have a couple of TB of SSD storage for like a working space. The budget for PC considers: CPU CPU Cooler RAM SSD Storage Motherboard Rack Chassis Note: I don't really need a detailed list of the hardware according to my specs. In Chile is kind of hard to get hardware as easy as you guys (US and Canada) can get. So don't worry about that. I need ideas on how to implement this correctly, so I can take off from that. So a budget on US hardware according to my needs is more than useful too. I don't know if I'm missing something, but just ask, and I will be answering. Thank you in advance Edit: I know the budget is kind of garbage for this, but I can't do anything about it. Also, as it is institution money, I can not buy used. That's how science and science money works around here

Budget (including currency): 3000 Country: USA Games, programs or workloads that it will be used for: Computational chemistry research, specifically Maple, GAMESS, Gaussian, TensorFlow, Python, PyTorch Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): Hello everyone, my wife was recently hired to become a professor of Chemistry and is looking to put together a workstation. While she will have some access to supercomputers, she would like to be able to do as much of her work locally as possible. While she has been able to talk to some advisors, none are super knowledgeable about PC hardware specifically, most just order what Dell tells them to. Her work uses the above programs and has an emphasis on machine learning and electronic structure theory. While she does have a budget up to $3,000, she also doesn't want to overspend on anything, so feel free to let us know if something seems overkill to you.

I ran across this article the other day from NASA and it's cool to see something like this. Makes you wonder what else is out there we've yet to see. ATM it isn't "known" as to what it truly is yet and the article indicates such, so take it with a grain of salt. Still cool though. Hubble Sees Possible Runaway Black Hole Creating a Trail of Stars | NASA

The Hubble Space telescope launched back 32 years ago, gave the world a glimpse of what's beyond our Solar System, and now it's getting extra years of life as NASA and SpaceX plans, Polaris will being its first space walk mission in March 2023 and if it's successful, then they're planning to perform another one, this time on the Hubble, to perform some service work, like replacing them gyroscopes that controls Hubble's telescope, where only 3 out of 6 remains in working order. For the boost, SpaceX's Dragon will dock with Hubble and bring it from its current orbit of 535km up to 600km, the original orbit altitude launch back in 1990. Without the idea of boosting Hubble, NASA would have to send a module and bring it safely back to Earth, but with the boosting idea, Hubble may see an extra 15 to even 20 years of orbital life.

I'm sorry if people have already seen or posted about this, I didn't see this after searching for it. It didn't seem to fit in the console section, either, but maybe that's my lack of clear judgement. My apologies. Delete or move if necessary So, I saw this ad on Facebook a few times, and I'm surprised I didn't see anyone else talk about it. Either from how cool (or how stupid) it sounds. Basically, it's a scientific instrument, but it's also a... game console. You play the games (the games are VERY simple by the way. Space Invaders level), and these liquids drip through these nanopore things. This does some science stuff, and depending on what game you play, you're basically researching different parts of biology and stuff. Seems pretty wacktastic. Please go to their website and read what it's all about. If it's true and they can pull it off, it would be pretty dang cool. But it's also from an ad I saw on Facebook, so I'm not exactly itching to support it right away for obvious reasons. Or really believe what I see. It's Facebook after all. All pictures are from their website, they have more info there. I don't know about "Investing" in their stuff, as I don't know the legitimacy of it all so far. Cool to think about, though. The screenshots with the drawn TV are apparently from the actual data and gameplay (quote from their website, was a GIF). Molecular Reality Demonpore 64 page

I want to try a lot of different experiments on computers and laptops and this one popped into my mind. Now there are some people out there who have aluminum heatsinks and everyone should know copper is way thermally conductive than aluminum. Now I thought of getting a thin copper sheet (probably about 0.3mm) and sticking it in between a CPU and aluminum heatsink and adding thermal paste in between them both. But still the aluminum would only pick up heat the same as if it were on the CPU. I did some more research and found some copper based gasket sealant. Then I had the idea of merging the copper sheet to the heatsink with the sealant instead of using thermal paste. So I'm here asking for peoples opinion on if they think this would work. I put a little diagram below on how it is supposed to go

Not really tech news, but I figured people might enjoy seeing some pretty space pictures. Summary After years of hard work coming up with data reduction strategies and solving associated technical challenges, astronomers have now have now published a series of recent results from the International LOFAR Telescope (ILT), demonstrating its power to shed new light on the Universe as seen at the lowest radio frequencies to reach the Earth's surface. With the ILT we can explore the low-frequency Universe in unprecedented detail and depth. It has a nice tech aspect as well. With 72 stations spread across Europe, over 70,000 antennas work together sending data to a central location in the Netherlands where it is pre-processed (true raw data is too much to store) in real time. The entire array produces data of the order of a dozen Tbps, needing to transport data over long distances at ~150 Gbps. A few PB per year is stored in the archive. During it's start in the early 2010s this telescope was a good infrastructural workout both in terms of long distance data rates and facilitating large storage requirements. Quotes My thoughts I'm part of the team and have been working on this for a few years now. I'm involved in these results, so naturally to me this is all amazing This holds great promise for the future and will help advance our understanding of black holes, (radio) galaxies and the connection between their evolution. Feel free to ask questions about any of the results or LOFAR and I'll do my best to answer them.

Ok this is a really dumb idea but I'm just gonna say it anyway. so we all know that alot of cpus have integrated graphics like the ryzen 3200g with Vega 8 which is a pretty good example as (especially in these times) if you don't have any way of getting a gpu it servers as an ok alternate. so i was thinking, what if we somehow put a socket on a pcb and put it in a pci express lane and somehow focus on the integrated graphics part of the cpu. now i wanna say that i am an idiot who doesn't understand fully the processes of a gpu or cpu work and also know that what I'm saying could be interpreted as "pffft why cant we have chips that like do graphics and stuff lol". but I'm talking about literally taking a cpu and putting it in a socket that goes in a pci express lane. I've included some beautiful artist renditions of what I'm visualizing.

Budget (including currency): Around 5,000 USD Country: Mexico Games, programs or workloads that it will be used for: Bioinformatics software, R Bioconductor, Illumina RNA-Seq, STAR Aligner, samtools, etc. Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): Im helping my brother who just finished his Phd on bioinformatics and will most probably be working as freelance when his university grant ends next this year. I want to help him build a good PC so he can do work. lucky he has some freelance jobs lined up so I believe it would be a good investment to get something good. I have in mind a Threadripper 3970X altrought I would probably wait to see what comes out on the Zen 3 presentation. I have a doubt regarding RAM I know that he needs quite a bit of RAM but I was wondering regarding the usage of getting ECC UDIMMs instead of regular RAM. His currently lab computer form the university is a Mac Pro circa 2012 with dual 6-cores Xeons, so I guess the Threadripper would wipe the floor with this. Any thougts or suggestions, I have never build a Threadripper nor used ECC Ram Thanks

Hi, I'm a physics student, and i need a recommendation for the most appropiate version of Linux that will help me in my research, any suggestions?

I watch Isaac Arthur every Thursday and he covers many sci-fi ideas and technologies, but he is very broad. John Michael Godier is also good but he has a very infrequent posting schedule for videos. What.If on Facebook postulates a hypothetical scenario every 2 days or so but a lot of is never technology. The Science to Technology channel has an episode every Friday called Future Friday, but most of the stuff he covers is emerging technology. I'm looking for something that postulates unique sci-fi technology/inventions/ideas every few days or every week. Does anybody know of a blog/site/channel that does that. Extremely amateur sites are VERY welcome e.g. BlogSpot. It just has to be consistent and ongoing.

So I found this Tesla K40 on newegg for like $100. Are they useful for anything? Could you use them as a folding card? Its so cheap I just want it ?? https://www.newegg.com/hp-model-f1r08a/p/1DW-000D-00025?Item=9SIA5HA8JJ0069

Better yet, use that WC IHS they reviewed a little while back and see if they can get even lower temps at 5GHz on the same CPU they tested originally. Edit: They reviewed a product!

Hi Guys, I work as a scientist in infectious diseases and with my work I do a lot of data science, genomics (the study of 'BIG' digital genetic datasets) and countless other analyses and techniques in silico. I consider myself a power user, I use Linux systems primarily and have a keen understanding of Bash shell, scripting in various languages etc - however my primary expertise is not in the creation of informatic tools, but using them to complement my work in the lab. I often use janky programs written by people with varying skill levels, to get jobs done during my analyses. So I find myself compiling stuff, delving in to deep dependency holes in attempts to get stuff to work. The problem with this is that my machine (i7-7700, 64GB, 256 NVMe, 1TB HDD) running Ubuntu has started to get bogged down over the years - entirely by my own fault, I'm sure. But I've seen this as an opportunity now, to go full virtual on my next overhaul/cleanboot. I'd like to basically have my host workstation running Linux VM(s) with the highest performance possible, with a virtual image that I can offload at the end of the day, on to removable storage so I can work on it at home or on my laptop. We have HPC facilities, so I'm not worried about losing raw compute performance on the wrokstation VMs, I just want the cleanest/quickest VM user experience possible - with the 'portable aspect' incorporated. That way, when. a machine gets slow, I can burn it. Or if I know I'm going on a program installing rampage, I can do so on a burner VM until I find the right recipe. I use the 1TB HDD as a shared drive for the VMs to store all large datasets on, so I don't duplicate - and when I need to take data away, I can pick and choose the files I need to offload at the end of the day. I store the VMs on the host NVMe drive. So....I've noticed moving VHDs around is super slow for some reason, definitely not USB 3 speeds. Am I doing something wrong? Secondly, what can I do in terms of removable storage? A caddy for an M.2 drive to decant the VM on to when I want to go mobile, or will there be bottlenecks? And I think finally, are there any better solutions to what I'm trying to achieve? I use SSH a lot, but sometimes you just want your desktop environment, and all your toys, so I'd like a GUI, and TeamViewer is okay, but inherently slow, so I'm over that. I think I've effectively described my situation here, as well as providing my life story, so I welcome any help anybody has to offer. I'm really in to my hardware and going the extra mile to get added/cool functionality so hit me with your best! Thanks! Dan

For the past few years I've been struggling with depression. Part of my treatment has been neurotherapy. It's really fascinating technology. The basics are that your therapist places electrodes (I think that's what they're called) on your head that are connected to a computer. Then the software uses the location of the electrodes, plus visual and audio elements from a tv, to help your brain build healthier pathways. You can watch movies, or even play some games, while the software does it's work. Oh, and I haven't experienced it, but they're working on a VR version as well. For me, it's been very effective. I'm on medication as well, but when I've missed a neurotherapy session for longer than normal, I definitely feel it. There's been times where I'm at a 5, on a 1 to 10 scale, at the start of a session, and by the end I'm up to a 7 or 8. (Haven't reached 10 in years... Depression sucks.) The place I go for both neurotherapy and Counseling is CAFA. (Christian As Family Advocates) http://www.cafaweb.com/ Their offices are in Eugene, Oregon. They provide a lot of family and mental health services. Don't let the "Christian" part scare you. Both my therapist, and I, are committed Christians. Yet he still only brings as much of our faith into our sessions as I want. If you are not a Christian, they are not going to push any religion on you. If you live near Eugene, and are struggling with depression, I highly recommend calling and getting on a waiting list, or just seeing if you can see someone quickly for neurotherapy. (Yes, they are that busy.) The system CAFA uses is Cygnet. http://www.beemedic.com/cygnet.html Ok, so here's the video idea. I think this does fit LTT's interest in the intersection between daily computer stuff and the deeper science stuff. Like the recent video on the gravitational waves observatory. Plus, there are games. Seriously. "Play games to fix your brain!" sounds like a good LTT video title. :) If I were to plan the video, I'd do a section on the theory and science behind the technology. Then a section on how it's used in the real world. Ideally at CAFA, rather than a place with the money to have all the bells and whistles. That would give people a good idea on what it really looks like in the real world. Finally, and this is what made me think the idea through... It would be a fun to see LTT work with their sponsors to get CAFA some hardware upgrades. There are times I can hear the laptop's fan roaring at max, even over the sound of the tv... So some more powerful pc's might help. Also, they are using the TV speakers. A sound bar, or something, would be pretty cool. Finally, I don't think CAFA is going be able to get on the new VR features any time soon. So outfitting them with some VR sets compatible with their software and systems would be amazing. Of course, I really have no idea what all they actually need. So you'd want to double check what you get them will be useful. Anyway, there's my idea. :D Oh, and if anyone in the Eugene, OR area wants to talk or hang out, email me at me@davidreagan.net. Especially if you're like me and depression and other issues make it hard to get out and find friends.... *coughs*
