Budget (including currency): 10K-15K Euros Country: EU Games, programs or workloads that it will be used for: Ubuntu, R, Python, Software requires high-end GPU for calculations 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): Fresh build. Hi, I am a Ph.D. student in live sciences, and I need to analyze large datasets produced by NGS (next-generation sequencing). I use Ubuntu for convenience and community support. R and Python are the main languages that I use, and objects that we are working on are reaching 70-100 GB (in the future, I probably need more). And some packages require raw data to work with, in these cases it requires to use 32-64 threads and >256GB ram. And, some other packages require high-end GPU (with ram and compute power). Since lots of packages and tools are in constant development, there is a constant flow of errors, and some of them require administrator privileges to fix them. For this reason, I cannot use shared server space (most of the time, response time and solutions are too slow for this kind of work). Some of my colleagues solved their problem by getting a high-end workstation. Our IT department requested for me to come up with a list. Since my tech-savvy is limited to upgrading the SSD on my laptop, I want to ask for your recommendations and opinions. I think these are what I need; high thread CPU (>=64) high/reasonable fast RAM (ideally 512 gb) High-capacity storage for passive files (HDD min 20 TB) Fast storage for active projects (nvme SSD type min 4 TB) support for multiple Nvidia GPU support for 10 gigabits ethernet speed Thanks in advance for your time, input, and opinions.

my friend started his college studies in biochimestry and it appears his old laptop is not enough anymore (intel 7th gen with 8gb mem and a limping battery). its been a while since i looked for a laptop, and idk how to search for one without a dedicated GPU so help me please. his requirements: MUST not big (so 15.6 or smaller) num pad high battery life (high as can be but there's no specific number) 16gb ram or more i5/i7 ro r5/r7, powerful enough to run r. SSD 128gb or more (while total storage is x>256) PREFERED backlit keyboard screen with >=300nits and/or can go low brightness for energy saving. good kayboard (will write alot) a way to connect to a tablet\ipad (i guess to transfer handwritten notes from lectures and homework) spec that will last for the duration of the degree (3yr) or more NICE TO HAVES touch screen nice sound for movies OR bluetooth for headphones ram expansion slots USES: there is NO requirement for gaming since he games on a PS4. movies and web browsing the main use will be studies which means a lot of writing papers and some and coding in python and R. he said he'll code with linux but idk yet if he will need to install the OS on a partition, run it on a VM or use an ssh to a college server. so if there are any biochemists here who know if he needs a GPU to run R code on a VM then please let me know. the reason he prefers a new laptop is because he has a scholarship that gives him about 850USD to spend on a laptop, and the rest he will get out of pocket. i'd appreciate any suggestion on how to search, personal experience on specific models. but if you are someone who like to help find the laptop right where i am then bless your sould, and here is a link of a site that searches stores in my country with google translate (budget up to 4500NIS): https://www-zap-co-il.translate.goog/models.aspx?sog=c-pclaptop&_x_tr_sl=iw&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp

Hey guys I'm here with a more economic question this time. Does anyone know how to calculate the gini coefficient and draw a lorenz curve in R with the following data: Taken Fruits Rate 0 2 1 3 2 2 3 5 I especially need help with the commands. I just don't have those commands that I need. So far I put the numbers in but don't know how to do the rest. Thanks in advance!

So I have been getting into Data Analysis and to practice I decided something cool to study with lots of variables and order and plot, etc would be CPUs! Remember this video?: Well I decided to grab the spreadsheet Linus made and get to work on it but a few problems arose when I was done with it.. First of all it is quite out of date! It's 2017 and Ryzen is here. Today we started seeing the benchmarks of the 1800x and soon there will be more R7s and then the R5 and R3.. Wouldn't you like to see how these are compared to other existing processors in terms of cores, threads, price, TDP, etc? So you can get idea what I got check out this nifty little app i got going: https://vicbar.shinyapps.io/shiny_benchmarks/ The idea is to have ALL that info in a very explorable way with the power of the visualization power of the R programming language! The community project part starts here. I have the app and am actively developing it further. Its pretty bare bones still.. But most importantly the amount of info is very very small. The video above covers practically only Skylake and Broadwell CPUs, so I was thinking we could crowdsource a databank so I can we can keep up to date with this awesome time for the CPU market and have something that is ours. So that is what I propose. That you guys donate some secs of free time to fill this .csv file which I can use to update app quickly! :https://docs.google.com/spreadsheets/d/1C7OkqOMGur-9S__0Vsp8_k5ABcMcu645PA0Pm8kbhbc/edit?usp=sharing Check the app out, I find it pretty interesting to browse a data bank of CPUs like that, its great for some quick and easy visual comparison and benchmarking (prices and characteristics). Now I'll talk about the future. With this spreadsheet Linus also gives on about GPU overclocks, I haven't gotten to that one yet but I plan to, maybe. What I really want is to have a comparison about the different sources we as tech enthusiasts get our info. i.e. Have one app where we can consult and visualize the different results that our favourite youtubers get from their benchmarking. I know it would be hard and maybe useless because of all the different methodologies they use, but I can help us get an idea, and a wide picture of what Ryzen (or any other future hardware) has to offer. (looking at 180ti). So concluding, I am going to go on analyzing and playing around with data, I hope some LTT forum members come along for the ride and help in having our own data bank. Also if this goes well it can turn into larger and more interesting projects. TL;DR I'm doing a project and I could use a hand or two on gathering data on all CPUs. The columns I'm going to use are these, https://docs.google.com/spreadsheets/d/1C7OkqOMGur-9S__0Vsp8_k5ABcMcu645PA0Pm8kbhbc/edit?usp=sharing Feel free to edit! I'm doing so to make this small app more useful and I make this project available to the LTT Community: https://vicbar.shinyapps.io/shiny_benchmarks/

ok so what do you need to water cool I want to get it for my pc and like how do I do it I literally know nothing about except that it looks cool and it keeps your pc cool

I was OCing my cpu from Ryzen Master Utility when I turned of 4 cores by mistake. I set Cores Disabled to 4 Cores. The motherboard that I am using is MSI B350 Gaming Plus. Can someone please guide me where to enable the 4 cores again?

No, there is no error in the title. The language is called R. So... We are currently using a language called R at one of my courses in college. We were given the task to calculate the contingency coefficient of two lists with the following command vcd::assocstats(table(x, y)) The problem is that when I try to execute that command I always get the following error and I don't have a clue what it means. > vcd::assocstats(table(list1, list2)) Error in sort.list(y) : 'x' must be atomic for 'sort.list' Have you called 'sort' on a list? I thought that atomic variables are for multi-threaded applications, but I don't use multiple threads (I don't think that R can even do that...). Or does the word atomic mean something different in R? Best regards, Rising Warrior

Hey guys, I just started out with Google analytics and AdWords as a side hobby and now I am certified for both of them. This made me wonder which other certificate I should acquire to be able to land a good paying job(though freelancing is my thing). Also I have started with aws and azure. This made me wonder whether I should get certified (entry level) with all the three platforms or just follow one for my career. My focus is big data and thus it would be great to get some veterans advice

Well this might be a little too easy to be an actual question, but I'm learning how to use R studio and it's a bit hard to get to know how to use some functions/commands. Basically I have 2 columns, the first one has the data I want to plot and the other one has labels. How can I sort the data on my dataset to I only use the data from the first column acording to the label I pick? (edit) I think I was being to vague, attached an image, basically I want to pick evvery element in the column 1 matching protein in column 2, I am sure I am using "subset()" the wrong way

Hey, so a teacher and friend approached me to help them build a PC, which will be used for Data Analytics and Science for a strtup, he asked me because he knows I know how to build a PC. It will mainly be used for R and Python, they gave me a $1100 budget (Windows +´Monitor + IO). Well, here´s the list: PCPartPicker part list: https://pcpartpicker.com/list/X7p64q Price breakdown by merchant: https://pcpartpicker.com/list/X7p64q/by_merchant/ CPU: AMD - Ryzen 5 2600X 3.6GHz 6-Core Processor ($219.89 @ B&H) Motherboard: ASRock - X470 Master SLI/AC ATX AM4 Motherboard ($129.99 @ Newegg) Memory: Corsair - Vengeance LPX 16GB (2 x 8GB) DDR4-3000 Memory ($159.97 @ Amazon) Storage: Western Digital - Black NVMe 250GB M.2-2280 Solid State Drive ($99.89 @ OutletPC) Storage: Seagate - BarraCuda 1TB 3.5" 7200RPM Internal Hard Drive ($42.89 @ OutletPC) Video Card: MSI - Radeon RX 560 - 1024 4GB AERO ITX Video Card ($149.99 @ Amazon) Case: Cougar - MX330-X ATX Mid Tower Case ($38.99 @ SuperBiiz) Power Supply: Corsair - CXM 550W 80+ Bronze Certified Semi-Modular ATX Power Supply ($38.98 @ Newegg) Monitor: Acer - G247HYU 23.8" 2560x1440 60Hz Monitor ($199.99 @ Amazon) Total: $1080.58 Prices include shipping, taxes, and discounts when available Generated by PCPartPicker 2018-07-14 17:51 EDT-0400 It´s my first time building a PC for this purpose, but since its for this type of work, so I want to know if its adequate. I want to clarify that the reason why I am going X470 is because of the Motherboard WiFi, Bluetooth, but above all, the AMD StoreMI Technology. I selected a Radeon GPU for their incredible computing power at reasonable prices, and since it is computing, apparently there is no benefit from a Quadro or a WX Card (according to a Game Dev I talked to). The SSD is NVMe instead of SATA because it appears to be beneficial for this type of work to have quick transers. P.S. I would love it if you could reccommend me cheap (but great) ATX Mid Tower Cases. I am in between a Cooler Master N400, N600, a Cougar MX 330-X or 330-G and the NZXT S340. It just needs two fans at the very least.

Looking for some guidance for a home office server with the following use Network storage: Music, photos etc Automated backups (specific folders, manual images) Automated data scraping (simple python scripts) SQL Server Offloading data processing. Not working with "big data" per se, but I do regularly consolidate several data sets (measures 2-4 GB in memory) and perform simple calculations after consolidation (ratios, counts, event returns, etc). I have had a few R scripts take >6 hrs to process taking up all the cores on my desktop (yes, I know that R is not the most efficient language, and I am working on re-coding in python/sql). Offloading Bayesian/ML models. I am thinking of implementing VM, so that if one thing crashes not everything will. I don’t need things to be done right away, just looking to offload so that I can keep working ahead or on something else on the main desktop. This will be a budget-ish build (all preliminary) Ryzen 5/7 16 to 32 GB memory SSD Boot in RAID ? (or no redundancy and have a backup image) 2x HD for Network Access Storage in RAID ? 2x HD for Backups in RAID ? Integrated graphics/low end GPU with option to upgrade once all the crypto in the world has been mined. So what are my questions? OS Recommendation (Windows v. Linux) Virtualization software recommendations (VirtualBox, VMware etc) SQL Server recommendation (SQLite, MySQL etc) Remote software recommendation Backup software recommendations What HD controller options should I consider (RAID 1/5, SAS vs SATA etc) Thanks in advance for your help,

I have this problem with booting. My keyboard does not seem to respond when I go to boot so I cannot enter BIOS or Boot devices. I do not have a extra keyboard around so I cannot test it with another. Here is a video from twitter th at will show you what is wrong. Video of problem Update: I reset CMOS and I tried the top right and left USB places and the keyboard does not respond. I will go to office depot tomorrow and get a cheap $10 keyboard and see if it works. Will update again
