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

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.

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.

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

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.

It's not the first time that our closest relatives surprise us with unexpectedly intelligent behaviour. But this time, scientists have found that in certain groups of chimpanzees, located in west Africa, the animals are capable of competently handling a topic that overburdens even some of us. Whenever a major game title is released, the publisher gives you the option to "pre-order" the game (George Carlin already pointed at the overuse of the prefix "pre" in his airline sketch). Pre-ordering a game is (usually) not any different from just "ordering" a game, except you don't get the game yet. As the sane mind quickly concludes, this is a rather stupid thing to do. Latonya Williams, an economy expert, confirms: "By pre-ordering a game, you take away financial risk from the publisher. Sometimes the publisher gives you a reward for that, like a rebate or exclusive in-game items, but otherwise you basically give a loan with zero interest rate." An additional drawback of pre-ordering a game is that you don't know what you get. Usually, pre-order phases start long before the game is close to being finished (or what the developer calls so), and therefore no external reviews of the game are available. This has led to some frustration as some pre-orderers have found that a game's quality sometimes does not match the announcements and advertisements of the developer. So by not pre-ordering a game, not only do you get financial advantages, but also you can read external reviews and inform yourself about the game that you are interested in, which can actually lead to the decision to not buy the game. Now the chimpanzees are clear about this, and most of today's gamers have understood this as well, usually by the aforementioned experience. But there are still many people who pre-order games. We don't know what those people would feel if we told them that they are outperformed by a bunch of west African monkeys when it comes to game shopping. This way, the average chimpanzee estimately saves some hundred dollars per year by not pre-ordering games. If this advanced technique applies to music albums or books as well, is now the essential object of research. Maybe we'll be surprised another time.

So i'm going to college soon and my college course requires a PC/Laptop with decent performance capabilities since the ones they provide can basically run Word and that's it (90% of them are on VISTA!) I'm going to do Computer Science A level and hopefully further. Please help me design a build for around with at lease 16gb of ram an SSD for OS and at least 2TB HDD for £700 minus and in a case around the size of an XB1. I have a spare win10 key lying around so the OS does not have to be included in the budget! PS: I would prefer a laptop for its portability and because it already has a screen and keyboard which are not factored in to the above mentioned budget so if you could suggest a laptop sub-£900 that would be the best! Thank you for any help given as I am rather busy with the exams/ Mocks and course work at the moment and don't have much time to do it myself. -Scrub

Duke University http://pratt.duke.edu/about/news/cooling-droplets Seeker News: New technology adds a third dimension to cooling modern electronics By Ken Kingery Engineers have developed a technology to cool hotspots in high-performance electronics using the same physical phenomenon that cleans the wings of cicadas. When water droplets merge, the reduction in surface area causes the release of a small amount of energy. So long as the surface beneath is hydrophobic enough to repel water, this energy is sufficient to make the merged droplet jump away. On the wings of cicadas, this phenomenon drives droplets to catch and remove particles of dirt and debris. In the new cooling technology created by engineers at Duke University and Intel Corporation, droplets jump toward hotspots to bring cooling where the electronics need it most. The results appear online on April 3, 2017, in the journal Applied Physics Letters. “Hotspot cooling is very important for high-performance technologies,” said Chuan-Hua Chen, associate professor of mechanical engineering and materials science at Duke. “Computer processors and power electronics don’t perform as well if waste heat cannot be removed. A better cooling system will enable faster computers, longer-lasting electronics and more powerful electric vehicles.” When droplets merge on a super hydrophobic surface, the loss in surface area releases enough energy to make them jump up off the surface. The new technology relies on a vapor chamber made of a super-hydrophobic floor with a sponge-like ceiling. When placed beneath operating electronics, moisture trapped in the ceiling vaporizes beneath emerging hotspots. The vapor escapes toward the floor, taking heat away from the electronics along with it. Passive cooling structures integrated into the floor of the device then carry away the heat, causing the water vapor to condense into droplets. As the growing droplets merge, they naturally jump off the hydrophobic floor and back up into the ceiling beneath the hotspot, and the process repeats itself. This happens independent of gravity and regardless of orientation, even if the device is upside-down. The technology has many advantages over existing cooling techniques. Thermoelectric coolers that act as tiny refrigerators cannot target random hotspot locations, making them inefficient for use over large areas. Other approaches can target moving hotspots, but require additional power inputs, which also leads to inefficiencies. A schematic of how the new jumping droplets electronics cooling system works The jumping-droplet cooling technology also has a built-in mechanism for vertical heat escape, which is a major advantage over today’s heat spreaders that mostly dissipate heat in a single plane. “As an analogy, to avoid flooding, it is useful to spread the rain over a large area. But if the ground is soaked, the water has no vertical pathway to escape, and flooding is inevitable,” said Chen. “Flat-plate heat pipes are remarkable in their horizontal spreading, but lack a vertical mechanism to dissipate heat. Our jumping-droplet technology addresses this technological void with a vertical heat spreading mechanism, opening a pathway to beat the best existing heat spreaders in all directions.” There is still much work to be done before Chen’s jumping droplets can compete with today’s cooling technologies. The main challenge is to find suitable materials that work with high-heat vapor over the long term. But Chen remains optimistic. “It has taken us a few years to work the system to a point where it’s at least comparable to a copper heat spreader, the most popular cooling solution,” said Chen. “But now, for the first time, I see a pathway to beating the industry standards.” This work was supported by Intel Corporation and the National Science Foundation (CBET-12-36373, DMR-11-21107, DGF-11-06401). “Hotspot cooling with jumping-drop vapor chambers,” Kris F.

I commented on the video itself, but I just wanted to post it here. This is my hypothesis based upon my knowledge of general science and thermodynamics. What are your thoughts? --- I think the reason that this is "mindblowing" is because no one has ever really done it to a computer like this before. For them to disclose how they did it is like trying to make thermodynamics classified, lol. It's essentially just an A/C system that uses the heat-pipe principle and goes out to a gigantic radiator. It works better than standard heat pipes because of the refrigerant. -Refrigerant has a very low boiling point -Heat travels from hot to cold -Any substance that is heated in a container gains pressure -Pressure also goes from High to Low Since refrigerant has such a low boiling point and the space between atoms is usually exponential with pressure, the heated refrigerant can easily gain tons of pressure from a smaller change in temperature. Likewise, the higher the velocity of the atoms (from heat and pressure) the quicker they can release that energy into the heatsink. This could explain why the tubes used are so small, so the refrigerant can exit the block at high velocity for better efficiency. Basically, these are just "high performance" heat pipes if you will, but here's the other side of it: Directional Flow. The basic solution that can be assumed, which is what is probably is, is one-way "gates" that only allow high pressure to flow to low pressure. If you don't have them, then all the refrigerant will go through both pipes to the heat sink and will not flow. If you have little "gates" that can only open one way (like most doors), they will flow one way. If it tries to go the other way, the door will close, pressure will build, and the next door will open and this cycle will continue. *Edit: Imagine it like a backwards Schrader valve, except you have a little plate instead of a needle and there is no spring, just pressure.* The only reason that this is "weird" is because most refrigerated appliances (refrigerators, air conditioning, etc.) are trying to cool items that are below room temperature, so they need pumps and condensers to do so. This is the opposite as the items that are being cooled are above room temperature. Thermodynamics is honestly one of the easiest but one of my favorite of the sciences. It's really cool to see something like this on a computer, but it's really nothing revolutionary. Now if you added a condenser and a pump you could have a lot of fun with it. ---

Well I just read in another topic that some of you guys here are actual scientists and engineers. Can someone look this idea over. An open ended string which has been expanding for 100 trillion years forms in to a quantum brane, a back bone to which multiple universe's stick to. Within the space of 5000 trillion years two quantum brane's have formed, due to the immense gravitational field between them they eventually collide. This collision would create energy equivalent to every atomic and non atomic explosive device, plus the output of every power generation facility / device over the course of 800 years, in less than a second. The length of the collision would be equivalent to the density of the gravitational field between the quantum string and the outer rim of the brane. If any of you are Theoretical Physicists i would very much like to debate this idea.

---Deep thoughts post--- So we are all made of matter; atoms, molecules, and elements. And matter cannot be created or destroyed, it can only change form. Right? Therefore it is safe to assume the stuff that makes us up, our bodies per say, were once part of something else. Maybe a part of the bone in my left finger was once in a dinosaur 280 million years ago. Maybe the Iron in my blood was deep in the earth thousands of years ago that was eroded from an underground stream that ran alongside one of the first civilizations. Maybe the sugar in my body was once part of, whatever you get the point. Basically all the stuff that makes me up today, wasn't always a part of me, and I wonder what infinite number of possible combinations came together to make me. (This includes the things I've consumed in physical development) No I'm not on drugs

Originally saw the link for this over on HardOCP and as a geologist, thought the concept sounded interesting so pulled up the article. A Geophysicist over at Stanford has developed a method to turn existing fiber optic infrastructure into a massive seismic network in order to create a higher density sensor. The technique works by measuring the backscatter signals from the fiber optic cable to measure the vibrations and strain on the cable. So far, they have run a trial using a 3-mile figure 8 loop on the Stanford campus and have been able to pick up small local tremblors as well as the recent Mexico earthquake. The array, while not as sensitive as a standard seismograph, can be used to distinguish between a magnitude 1.6 and 1.8 earthquake as well as pick up the different P and S waves. The biggest benefit from this is that the cost of using the existing infrastructure of fiber optic internet to establish this sort of network is less than installing seismometers, which can lead to more data and better coverage of cities. 3-mile fiber loop used for testing https://news.stanford.edu/press-releases/2017/10/19/building-billionr-optical-fibers/ While this is not as sensitive as a standard Seismometer network, I could definitely see this as being useful in large urban environments, especially for mapping out the substrate material of the cities, engineering more earthquake proof structures and potentially providing for a possible early warning system (although that part may be very limited in capability).
