How to retrieve Bitcoin Address / how to mine on it again?

Hello All,
My mining rig's HDD crashed and Windows is now corrupt on it. While I was able to retrieve my wallet just fine, I had a some mBTC (not sure how many, 1 or 2) on NiceHash miner which were not paid out.
Per their policies, they don't pay out anything under 0.01BTC (which is 10 mBTC).
Now, I might be able to get my old Bitcoin Address and worker name, as I still have the HDD and via Linux Live CD I can access those files. I am not sure where NiceHash stores that info, or if it is even retrievable.
How do I go about retrieving that info (since I have the HDD but cannot run windows on it and cannot run any windows with that HDD plugged in because it will not operate it)?
Say I find my Worker Name and Bitcoin Address, how do I go about telling my wallet to use that address? Or is there a way to tell NiceHash to apply the balance of the old address to the new one?
Thank you all for the attention!

Looking for some guidance on how to organize my Bitcoins

I've been following Bitcoin for a few years (since 2011), and I've done a lot mining, but I've never actually been in a situation where I've had to store coins long term. Now that I am, I was wondering if I could get some general input/advice on how I should go about storing my coins for hot and cold storage.
So far, I've printed a BIP0038 protected paper wallet with 7 addresses, from a non-network-connected Linux live-CD. No coins in any of the addresses yet. Beyond this, I'm not sure what the best way to proceed is.
What's the best way to monitor the addresses? I know blockchain.info has a Watch Only address option, but logging into the wallet account on that site is a bit of a pain (having to enter in your identifier every time).
How many coins should I have sent to one address before using another?
When it comes to a hot wallet, I'm thinking about using Electrum, mainly because I wouldn't have to download the entire block chain to use it. Would anyone recommend using something else?
Any input on my questions or just general guidance would be appreciated!

[Build Help] $1500 gamer, multi-screen capability, with some scryptcoin mining/protein folding/video editing on the side

I tried this in /buildapcforme and didn't get any response, but I don't think I need help from scratch since I already have an idea of what I want in terms of parts, so here's a shortened copypaste:
Uses:
Budget: As cheap as possible. I'll go over no more than $2000 if need be for the triple-monitor capability.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
If there's any specific features you want/need from the rig, please list them.
Do you have any specific case preferences such as a window or LEDs, or do you have a preference for low-noise components?

With that build, what are your thoughts on the 2x R9 280x's? I'm having trouble finding comparable benchmarks, other than this which only compares it to lower-scoring GPUs. I see them as providing a fair amount of number crunching capability (aka mining), as well as being still top-of-the-line graphics for gaming. I probably shouldn't concern myself with mining if I can get a better performance out of games with a single GPU for less $.
I've never SLI'd or CF'd and everywhere I see it mentioned, I notice people have problems with it or that it doesn't always work. What should I know about multi-GPU setups?
I notice a lot of budget builds use an AMD CPU. How much can I expect out of the 4770k over a similar AMD cpu like the FX-9590 or 8350 (a much cheaper one), aside from the marginal chance in benchmark scores?
I could save getting a cheaper PSU probably.
I live near a Microcenter. I'm guessing their prices are lower for pickups.
Sorry for the long post. I hope it doesn't scare anyone off! I'm just not going to drop $1,500 without properly educating myself first.
Thanks!

New Level of Jackassery: A Long-Winded Story of a Minor BitCoin Folly

[Throwaway for reasons soon be obvious.]
TLDR: I spent a lot of effort making a nice paper wallet that I promptly left on the trunk of my car as I drove away. I found it in the street four hours later.
I had been trying to put together a secure setup for creating paper wallets. My plan involved a spare laptop and a bootable USB drive running some Linux distribution. Once complete I would use BitCoin Paper Wallet to print a high quality wallet in full color on card stock, and even use the hologram stickers sold to seal them. Then I'd store them somewhere safe.
With small children, I do not get as much time as I like to work on these types of projects, but after a week had passed, after I switched from Tails to Ubuntu, and after I finally came to a solution to persistent encrypted storage on the USB drive when Ubuntu is running the LiveCD (LiveUSB), I did it.
A laptop of mine recently lost its screen in a tragic fall from a precarious position, it made for a perfect air gapped computer to boot my USB drive to. Boot, login to encrypted drive, install the necessary fonts, install the printer driver, print, cut, seal with hologram, insert into plastic sleeve, import address, transfer 1 BTC to address and store paper wallet in secure location.
A few days later I pull one of the paper wallets I printed from my secure location to take to a birthday party my daughters were attending at the house of a friend of mine. I thought my friend might appreciate it. I carried it in my hand along with my two kids, a present for the birthday boy, and everything else a father needs when wrangling small children. I struggled loading the gear and the children safely, and decided to set the wallet on the trunk of my car.
I distinctly remember thinking to myself, "Don't forget to pick that up." I loaded the car and drove away.
Two hours later, at a pirate-themed birthday party at which I saw two small children in a Jeep power wheels toy run over other children because they didn't realize there was a steering wheel, I froze and I am sure I turned ghostly white.
My instinct was to rush home immediately, but my kids were having a great time and I couldn't quite explain to our host that I had to leave to retrieve $800 worth of card stock I printed on my computer and left on my car. I simply had to wait. I felt myself start into the five stages of denial. First up, denial. Maybe I had gotten it, and just forgot. Maybe the aerodynamics of the car are such that the paper just happened to stick to the trunk just in front of the spoiler (if that's what Honda wants to call that little nub).
After we left the party, at which I saw a piñata with a trap door that the parents just opened to release the candy, we left for home. As I entered our neighborhood I retraced my path from earlier in the day. I scanned the streets looking for anything that looked like a plastic sleeve. I saw nothing on the streets that led to mine.
As I turned the last corner onto my street a small glimmer caught my eye. I focused on it and made out a rectangular shape. I quickly parked, pulled out the child old enough to not wildly run into the street, and proceeded to run into the street myself without looking for traffic.
There is was, my BitCoin, snug in its plastic sleeve no worse for wear. My fears that someone had found it and I would spend a lifetime following how it would be spent over the years were gone. And it was in pretty good shape. I don't live on a high traffic street, but we were gone for four hours and my BitCoin must have had a few close calls. The sleeve looked great, and my holograms do not appear to have been tampered with.
I'm still transferring the funds to a new address ASAP.
Edit: Moved TLDR to top.
Edit Again: temper = tamper.

BTC-E.com safety checklist for noobs

DISABLE JAVA There's java zero day exploits being discovered all the time. One exploit still hasn't been fixed. You should do this permanently with your browser java is an exploit factory. IE you can't completely disable java so don't use it.
INSTALL NOSCRIPT ADDON https://addons.mozilla.org/en-US/firefox/addon/noscript/ or whatever shit script blockers Chrome/Safari use because Chrome is still lacking the required infrastructure for selective script disablement and object blocking so noscript isn't available, but inferior clones are. Whitelist only sites you need, like btc-e.com so it doesn't automatically load harmful scripts on untrusted sites.
GET AN ENCRYPTED PASSWORD SAFE http://www.schneier.com/passsafe.html Don't use any solution that 'encrypts in your browser' because it will need java and we disabled java remember?
MAKE NEW GMAIL ACCOUNT JUST FOR TRADING Make a random account name + password that can't be guessed. http://www.passwordgenerator.eu/
Store them in your password safe so you don't forget them. Never reuse that password on any site. ENABLE TWO FACTOR AUTHENTICATION.
Note that 2factor ID sometimes doesn't work if your phone time is off. You get 30 seconds to type in the code, if off by 10 seconds derp run out of time. Set your time manually if the shitty telco time server is off www.timeanddate.com
MAKE BTC-E ACCOUNT Use impossible to guess passwords from password generator + throw in your own random letters. Save in password safe. Do not pick a name anywhere close to being your email username.
ENABLE 2FACTOR ID Click Profile, then click 'Edit'
https://btc-e.com/profile#edit/home - confirm your email.
https://btc-e.com/profile#edit/security - enable "Withdraw only with request on E-Mail"
DO NOT CLICK ANY LINKS IN THE TROLLBOX!!!! No matter how innocent the link looks don't click anything in the chatbox. Hackers are dropping links full of java zeroday, redirectors that look just like btc-e login page and phish for passwords, all sorts of bad. Trollbox is also prone to misinformation being that it is a trollbox. Avoid.
If you chat on there, expect every PM sent to you will be from a hacker trying to mine information or get you to click a link. Assume every link is an exploit attempt. Notice how it displays your name, if you picked same name as your email, they can go to work on both by trying to break into your gmail account. This is another way how people get their coins stolen. Hacker takes chat name and tries it on gmail/hotmail/yahoo. If they get in because you didn't set up 2 factor expect to be robbed of coins.
DO NOT ENABLE API Unless you know what you're doing, do not enable this. Liberty Reserve disabled their API by default because of so many drained accounts.
DISCLAIMER Of course, be aware the exchange is in Russia or possibly Bulgaria and if anything happens the owner could just disappear, but this is highly unlikely. Why would you walk away from a money machine. Remember bitfloor (US) lost all it's customers bitcoins once, CryptoXchange (Australia) stole from users and disappeared, Bitcoinica (China?) stole or lost all the coins, and bitcoin-24 (German) has just lost their bank account and owner MIA. All exchanges carry risk no matter what country they are in.
You can fund btc-e through cash deposit in India, Singapore, Malaysia, Bangladesh, Nepal, Australia with http://www.ecurrencyzone.net/ which are authorized exchange listed on the Okpay.com site. They sell btc-e vouchers and Okpay. So does http://liliontransfer.org/ for wires and other methods.
If you want a really secure platform (you fear your comp is probably already infected with hidden java zeroday botnet) then download any linux live distro and make bootable USB or burn to CD. I recommend Liberty Linux http://dee.su and just use the non private browser (disable java and javascript!), NOT the Tor browser you don't want to trust SSL over Tor and risk a malicious exit node capturing traffic and running sslstrip on it or feeding you a MITM attack with spoofed certs.
If you want to know why watch this, nothing has changed since this talk was given: https://www.youtube.com/watch?v=Z7Wl2FW2TcA

Prismed innocent until proven guilty: How I live with NSA Prism

A couple people have asked me details regarding some security tools I use. I figured I'd make a post for people who might be interested. It outlines some technical approaches and tradeoffs I make to retain some semblance of privacy in this modern Internet Age.
Our current administration has made it abundantly clear they could care less about the constitutionality of the Intel community's collection methods. For those who have been living in a cave (and ironically would then have nothing to fear from this), the NSA Prism program in cooperation with the FBI gives the government basically unfettered access to private information you have stored at many of America's major tech players.
The full extent of these programs is slowly being revealed, and the FISA court seems perfectly willing to allow ongoing telecommunication surveillance on American citizens who have done nothing wrong. They collect and store your information in bulk, but hold back on analyzing it. Once they go through the arduous process of legally gaining permission to investigate you, they can retroactively analyze what they have collected. It's a major loophole, but it works.
What's worse is many of the tech giants (Google, Apple, Verizon) have been playing ball silently since 2009, only pretending to care when a national PR embarrassment is thrown in their lap.
So to the point, I've been slowly removing my dependency on Google and other Prism choke points.
There's a great site I discovered from Hacker News: Prism Break. It outlines many solid alternatives for web services and computing tools that are unlikely to cooperate with Prism for a long time (if ever). As with most software, there are trade offs between the ease of use in mature commercial products and their privacy guarantees.
This post is about some of the recent changes I've made with respect to Prism-Break and my own research on Hacker News, Reddit, and general insider knowledge gained from working with smart technical people over the years. You'll notice a recurring theme of evaluating ease of use with security, and many of my decisions actually err on the side of usage, despite the tone of this post.
Web Browser:
I recently switched from Google Chrome back to Firefox. I always liked Chrome because of how quickly it rendered pages, particularly Javascript heavy pages, and made tab management easier. The web developer toolbox is second to none. Although I must admit, Mozilla Firefox has stayed very competitive with them. There is a negligible performance drop off, but it's barely noticeable and nothing significant. You can't really trust Chrome unfortunately, even with aggressive privacy settings (no analytics, etc.) . Firefox is not as malware/exploit bulletproof as Chrome, but it is close, and the open source nature makes it a very attractive alternative. I NEVER save passwords through the browser and always tell it never to ask. Both Chrome and Firefox are well know for storing passwords in plain text.
Web Browser Add-ons:
Not exactly a browser add-on, but it does help with security.
I pay $80/year for an OpenVPN subscription to Mullvad, which I discovered reading a comment thread on Reddit. They are based in Sweden and retain absolutely no information about you. They could give a fuck.
The OpenVPN standard encrypts all outbound communication from the originating device using layer 2 SSL. Traffic appears as normal HTTPS. This is different than other VPN technologies that use with IPSEC, the presence of which is easy to detect and thus limits any plausible deniability. It's also different than a simple web proxy that does not necessarily offer encryption to prevent ISP monitoring/throttling, and often only handles HTTP or SOCKS traffic, which is often slower. Mullvad is fast enough that I've just gotten in the habit of leaving it running at all times. Plus it never get old having sites show me geo-aware ads in Swedish.
The trade off is it's a bit more expensive than many of the web proxy providers. However, there are certain fringe benefits to having completely anonymous web traffic. Don't hate the player hate the game.
The fact that traffic is difficult to distinguish between secure web browsing and OpenVPN has made it an attractive countermeasure to the great firewall of China and other censorship technologies. There is a constant leap-frogging battle between those governments and OpenVPN vendors like Mullvad. It's reminiscent of the old PC gaming piracy protection vs. CD burning wars before everyone started using Steam.
Web Search:
I have configured Firefox to use StartPage as my default Search engine. They have a similar don't-give-a-fuck privacy policy to Mullvad (they're in the NE), and route all your searches anonymously through Google. It's not 100% equivalent to US Google, but it has not let me down yet. It's about 95% equivalent from my weeks testing it. There has only been one obscure search for this weird video it couldn't find. Not a big deal. For most of my research, it hits the mark. There is an extra half second of latency in the response, but I can deal with that.
They have a plugin for Firefox, but I've configured it to perform address bar searches by A) opening a new tab B) typing 'about:config' C) Searching for the property 'keyword.url' D) Change it to 'https://www.startpage.com/do/search?ie=UTF-8&oe=UTF-8&sourceid=navclient&gfns=1&q='
Maps:
You're basically screwed here. Nothing works like Google Maps. They are echelons past their competitors. I can say that having used OpenLayers and ArcGIS for some technical work in the past. Plus we all remember how good a job Apple did with their iphone 5 maps.
Just make sure you're not logged into your Google Account and preferably running OpenVPN when you do your search.
Instant Messaging:
This is the first example you'll see where I lean more in the ease of use than the security.
When I'm going to run IM, I use encrypted Gtalk over Adium.
Mainly because it would take too much effort to convince all my friends to use to a protocol that allowed true point-to-point encryption that's off the record. I use SSL between my host and the GTalk server, but Google still has access on their servers to the plain text messages (even if it's OTR I suspect, no proof though). Moreover, your chat partner may not be using it, in which case all those messages are still visible downstream in plaintext.
The only good alternative is just to stop using it so damn much. This is a work in progress for me.
Video VoIP:
Skype sucks. It really does. They haven't been the same since Microsoft acquired them. What's interesting is the tool was built with pretty impressive reverse-engineering countermeasures, and goes through great lengths to circumvent NAT in order to make your calls. Unfortunately there are known backdoors where third parties can ease drop. It is not to be trusted anymore for secure conversations. I don't make video VoIP that frequently anymore, but if I had to I would try out Prism-Break's suggestion for Jitsi. It looks promising.
I would also avoid Facetime like the plague, simply because I think Apple has zero credibility for protecting your privacy (just as Microsoft and Google).
Social Networking:
Not much you can do here if you enjoy the major players like Facebook. Similar to instant messaging, you're limited by the people you want to communicate with. I'm reasonable careful these days about what I post on FB/LinkedIn/Google+ when I use them (which is infrequent). And I don't mean just what is publicly available to my contacts. I mean everything.
I personally don't have a problem with these services and think they add a lot of value. I try to keep really personal stuff off them, but that guarantee is a bit naive. I know I've slipped up a few times, and FB has access to some pretty funny private messages. I mostly enjoy the read-only features of these sites, and rarely contribute, but that's not really good enough.
Just by having an account with some basic information and friend links, they can learn a lot about you. For example, one of my good friends likes to check all of us in on Facebook when we go to a listed restaurant. That's not even something I opted into, but FB gets to learn facts about me based solely on that association. I've met girls who later looked me up through FB friends and sent weird unsolicited PMs. We've all been there. Facebook, and thus the government, has access to all that shit. They even have a whole suite of creepy analytics that can tell if you're gay.
Cloud Storage:
This is one of the more interesting ones. There are so many choices for secure backups, but it's difficult to find a be-all-end-all solution that satisfies everyone.
I personally use per-file encryption on Amazon S3. It's the same storage backend as Dropbox, but I encrypted everything first by hand and don't bother with file sync.
My methods are simple but require quite a bit of micro-mangement. I run each file through a Mac OSX utility named crypt from the command line before I post it to my S3 buckets. The utility defaults to AES-256 bit encryption and is really easy to use. This custom version I modified for OSX cleans up the command entry a bit from the authors original version.
I will say there are very fancy solutions out there for users who demand a bit more.
Dropbox is really slick with file sync and ease of use, but everything is unencrypted on Amazon. Unacceptable.
To counter this, some people supplement Dropbox with a tool named EncFS. It transparently encrypts/decrypts file contents from any directory, which works with Dropbox, but you need to be a bit of power user to set it up. There's also Tarsnap, but it supposedly doesn't handle incremental syncs well and doesn't work on Windows. One interesting solution I looked at was using BitTorrent Sync to do cross-device backups and syncing, but I wanted something that backs up to the cloud, not just my own devices. There really is no easy-to-use solution that efficiently synchronizes files and is secure. Dropbox + EncFS is close, but not exactly easy to use.
Documents:
This one has been difficult. There aren't too many good solutions out there. I have looked at Zoho before and they offer a lot. It's hard to imagine it easier to use than Google Docs though. Prezi is cool for building presentations that don't look like PowerPoint vomit.
I really don't have a good suggestion here. If this became a frequent requirement, I'd probably create a new Google Account with some bogus personal information that wasn't associated with any of my previous Google Accounts. Although they could very easily correlate something written in one of my documents with a best-guess at a related Google account (also based on IP logging). Google's latest terms of service and privacy agreements allows for these types of cross-service analytics.
Media Publishing:
I use Imgur for everything.
Email Services:
Another interesting one. If I use an anonymous service like FastMail, but 70% of my emails go to Gmail recipients, am I really hiding anything from Google?
At the very least I'm not going to make it easy for them. So far I've been impressed with FastMail. The UI feels comfortably like Gmail, except much more responsive. It offers competitive features with Gmail like anti-spam, full text search, achieving, filtering and custom DNS. There are no ads, but it is a pay service.
Email Desktop Clients:
I haven't done this for quite some time. If I had to, I'd probably try Mozilla Thunderbird.
Email Encryption:
I don't bother with this. 99% of people don't want to fool with it. Just like with Dropbox + EncFS for file storage, most encrypted email systems require people who are somewhat technically competent. It's an unreasonable expectation.
Online Transactions:
Sadly I still use PayPal. A lot of people are attacking this problem right now (Stripe, Square, etc.) No one has come out victorious yet as the PayPal killer, but I am waiting anxiously.
BitCoin is a really cool technology that's gaining some traction, but many merchants don't yet accept it, and some of the security around wallet controls leaves a lot to be desired. It's interesting to read about how the currency works from a technical standpoint. It has resisted many attempts at exploitation and bot-mining, but the major weakness appears to be wallet security.
Android:
I dumped the NSA conspirator Verizon in favor of Solavei running over T-Mobile infrastructure. This involved forcefully unlocking my phone and installing a root kit to gain superuser permissions. If you're thinking of switching from Verizon to one of their competitors, don't try to port your phone unless you're prepared for USB debugging, ROM installation and a $15 unlock code (depending on the phone and whether or not you're willing to dig with a HEX editor). I learned a lot, but I wouldn't wish it on other people who just want their phone to work. I run CyanogenMod 7.2 for my Android ROM. I have no outbound encryption through for any of the common apps (Google Maps, Reddit, etc) so this is a weak point for me right now.
Operating System:
I run Mac OSX. It's just too smooth and efficient for technical work. I can't give it up. Linux is nice with respect to production scenarios, but the user-experience of most of the x-windows managers just doesn't compare to OSX. I'm very careful about what updates I perform though, and run Little Snitch so that I can approve and monitor any outbound connections my machine tries to make. It's technically possible Apple has baked some dubious reporting into the core apsd services, but there's not much more I can do without handicapping the machine.

Questions Answers
This just got cross posted to /sysadmin ; as a fellow research-field oriented sysadmin it gets worse... I too started in the Quake/HL/CS/TF timeframe, but got my degree in CompSci. Have you ever dealt with mice (the mammal kind; I've got worse stories)? Certs: just got my RHCSA this year. I've got the RHCE scheduled for october, and I'm studying for the CCNA, though I use HP switches.
How do you backup desktops / servers? Backups: Luckily, I don't do desktop support. We have another IT group that does that, I'm completely independent from them and I only have to take care of servers (and my own desktop). The physical servers are backed up to tape with Bacula. Our virtual servers are backed up with Veeam. My own desktop is backed up to my NAS share using synctoy (yes, i use windows on my desktop).
How much disk space do you have in one server? One off systems: As in physical servers built by hand? 0. I'm pretty much a Fujitsu shop with a few Dells. I definitely don't have time to be piecing servers together. disk space: only a few TB per server. I think the better answer would be that we have an Isilon X200 cluster that is 140 TB.
one off systems: As in physical servers built by hand? More as in unique software; such as this computer runs the HPLC. I guess in that case I only manage a handful of physical servers and a few VMs that are made for running one special piece of software or analyze data from one piece of scientific equipment. We have many other scientific devices that are attached to PCs that are "community" devices, but I don't have to manage them. and we've got a microscopy group that is separate from me too, with their own machines and devices.
If you are moving to 1gbs are you looking to increase the MTU? I was working on that but had some issues with firewalls for my windows-putty users. First, just to clarify, we're going to 10G from the 1G we have right now. I'm not our main network guy, so I'm not entirely sure but I doubt we'll change the MTU simply because we don't have a remote site so the majority of our traffic is regular internet traffic.
As for our backend network, I do use jumbo frames on a couple VLANs for our storage.
That most important question for any sysadmin...vi or emacs? Vi improved.
Anand Shimpi and Dustin Sklavos had an interesting podcast on the merits of Haswell on the desktop. In short, Dustin echos the enthusiast community's frustration with overclocking headroom decreases from Sandy Bridge Ivy Bridge Haswell. It seems like IPC has gone up but maximum frequency has gone down so the ratio seems almost 1:1. Then there is the issue of the use of TIM and IHS glue cap that caused some to delid their CPUs (and void their warranties). Question 1: What are your thoughts on the overclocking headroom decreases that we've seen? Question 2: Is Intel doing enough to cater to the enthusiast community? Question 3: How do you feel about the delay in the release of Enthusiast parts by Intel (Sandy Bridge-E & Ivy Bridge-E) versus mainstream parts (Sandy, Ivy, and Haswell)? Intel makes good chips and they do keep pushing technology forward, but they will never do overclockers any favors. They will always be doing whatever they can to make money. AMD will also do the same thing. Intel seems to think enthusiast solely means "deep pockets". At the same time, there always seems to be a lot of "the sky is falling" reporting done by many tech journalists. Intel hasn't completely forgotten about overclockers and I don't think they ever will completely let that group disappear. And really, what incentive does Intel have to completely lock out overclockers? Sure, deny us our warranty, we'll go ahead and buy another chip and give you more money. How could you deny that as a company? as for overclocking headroom decreases, one can only hope that means we've got a whole new architecture coming out soon, something like the transition from Pentium 4 to Core.
Do you have a home lab setup to learn/test on? If so, what does it consist of? At home I've got a 1u dell poweredge sitting in a closet which is my main server. I run bageez.us off it which was supposed to be my way of giving back to the community, by running a Linux torrent site. Other than that I've got two htpcs running Debian, a desktop windows machine for gaming/reviewing hardware, and a file server with 8 tb running Debian and KVM with a few Debian VMS.
Do you still have that site going? I tried your link but it didn't work. Looks like I let the SSL cert expire. I'll fix that tomorrow. It works on my end but I think I want to recode a few things and possibly get it to work with other trackers. Right now the torrents will only work with my local tracker.
Need to monitor that ;D. Yeah it's one of those things where I seem to be the only one visiting the site, so why stress about it. I also set up owncloud, but again, i'm the only one that uses it. :(
Do you get to keep the hardware you review? - Do you prefer the black theme or the white theme? Most of the time, yes.
Black. I don't mind the white theme that much tho. edit: he's asking about the forum default skin at overclockers.com/forums
What is your #1 piece of advise for any linux sysadmin? That's a tough one. Do you mean someone looking to become a sysadmin or one that is already a sysadmin?
I guess I didn't specify that did I? I ask the question because I've been doing mostly Windows sysadmin duties for about 2 years and some linux admin stuff. I'm falling in love with Linux and I would love to have a job dedicated to just *nix What advise/suggestions would you give someone that is wanting to make the transition? I think what really got me the best knowledge was forcing myself to use a "less polished" distro as my main rig for a few years. Once you are forced to learn, you'll learn quickly. Picking up an rhcsa book will help too even if you don't plan on taking the exam. Go through it and do the exercises. Install a distro, set it up, then format and do it all over. You can use virtual box for the same result without killing your main rig.
Do you still use FreeBSD? If so, what exactly do you use it for now? No, but I wish I did. I stopped using it because the GPU support in Linux was better on my desktop, and now I work mostly with CentOS, and it would be a lot of work to change 100ish servers over to FreeBSD.
What did you use to train yourself in everything? Just break and fix? Pretty much just the experience of using it daily on my desktop for years. Running gentoo and Slackware really gets you used to doing things for yourself.
Configuration management of choice for those 18 servers? I'm just a jack of all trades sysadmin with a strong focus on problem solving. Are you trying to cure cancer with those 18 nodes or mining bitcoins? I started playing around with puppet but haven't really gotten the hang of it. Right now the cluster is running ROCKS with Grid Engine, and I just use the rocks commands to provision/wipe nodes.
What's the hardest part about getting started with puppet? I think its mostly just finding the time to sit down and have enough time to emerse myself in it.
700+ centos nodes across a few clusters here and I'm loving ansible. Nice. I've heard that ROCKS becomes a bear at scale, but for now it's pretty simple and quick. My plan is to keep adding another 18 nodes every year (one full blade cluster) every year, as long as I can get funding, so I'm keeping my eyes open for other solutions for provisioning. Bright cluster manager is another one I have on my radar.
Computer didn't work for 5 months (it started then after i downloaded skyrim from steam it shut off, then finally worked last month). Put my new graphics card in, then problems ensued. Here: Link to www.reddit.com. 1st step i'd do is remove all nonessential parts from the computer. Leave the cpu and 1 stick of ram. Pull out the graphics card, don't connect any hard drives or cd drives. On the back, connect the monitor to the on board video card and connect the keyboard. Does it power on? Do you get any error messages other than it saying there is no OS? Then power down and connect things one by one until you figure out what part is causing the problem. If you think it's the drivers, you can boot into safe mode (i hope windows 8 still has that, press f8 while booting), then run Driver Sweeper, to remove the graphics drivers. I haven't tried this on windows 8 so i'm not sure if it will run or not. I don't think you need to do a full format and reinstall.
I'll try this tomorrow after work for sure. Do you reddit enough that i could contact you for more advice for help if i run into anything else? (i did contact nvidia team for help, they just told me to delete old drivers without any other help then those words). I don't blame you if you don't want to say you are able to help me with this situation. Humans be humans. Was there a specific reason to go into a cancer research lab? Or was it just a job that came around? No I don't go into photoshopbattles. I pretty much just do what I need for websites and that's it.
How do you like your baked potatoes? (please get into specific detail). It just happened to be the job I found but I love the environment. Much different than a corporate job.
I'm not a fan of baked potatoes but I do love curly fries if that counts for something.
You should really join us in the BAPC IRC channel. I do hang out in the unofficial Overclockers.com irc channel quite a bit. I'll try to drop by.
Do you do any sort of automation for firmware updates? Firmware automation? Nope, and I don't think I'd ever want such a thing. I've been looking at puppet as a way to automatically update software though.
I saw below you guys have some Dell servers, what models and do you use their Lifecycle Controller? We have a couple r610 servers and an equallogic storage box. I haven't heard of this life cycle controller.
What are the specs of your personal rig? Intel i7 3770k @ 4ghz.
Zalman CNPS9900LED cooler.
Patriot ddr3 2x2gb @ 800mhz cas7 (rated for 1200mhz cas9 but I can't boot at that speed anymore for some reason)
MSI Z77A-G41.
ATI Radeon HD 6870.
OCZ Revodrive X2.
How come you have a 3770k but only 4GB of RAM and a 6870? Seems a little overpowered in the CPU category. For benchmarking, mainly. The 3770k was our standard platform for reviews when I bought it. The rest is leftovers from various reviews. We don't get paid, so basically we work for hardware when we write reviews, more or less.
Wait when you review hardware you get stuff? Yes, hardware vendors provide review samples.
Have you ever had an OEM send you equipment different from the consumer version? (Say a factory overclocked version) and claiming it was the standard. Nope. Even if they did, we'd certainly review it as the hardware is, not as they intended it to be.
What's the worst PC loadout you've ever seen? PC load letter? What the f does that mean?
[email protected] JK, doesn't work well on a cluster unfortunately. Unless you have any perls of wisdom on how to make it work on a cluster? Well, it would work just as it does on any other group of computers. I'd have to run one client on each computer and they'd all check back to get their own workloads, so it would really take out the "cluster" usage and turn them just into regular blade servers.
How old are you? Young 30s.
Have you gone to college and completed a bachelor's degree, if not, do you regret it? Yes, BS in Mechanical Engineering.
How did you prove yourself to be worthy of that initial Jr. Sys. Admin job? I listed everything I could think of that I've done that was computesysadmin related. I had administered several web servers over the years, and experimented with many different distributions as my daily driver on my main desktop, so I was very comfortable on the command line and with day to day tasks. I was asked a few 'test' questions on the interview but I think they were more to gauge exactly what i did and didn't have experience with, not so much to make or break me.
Lastly, congrats on doing what you love for a living. Cheers to your future. And thanks. i definitely wake up in the morning with a different attitude than i used to, and that makes a big difference.
Configuration Management / Vagrant / Clouds. I have start playing with configuration management, but haven't gotten anything in production yet. I only provision new VMs every once in a while, and once the computer nodes are up they are pretty stable.
What is your scripting language of choice? I use straight up bash for most things, and python for some. I'm trying to learn more python.
How do you feel about some distros moving away from init.d and going to systemd? I like init.d because it's what I know. Systemd is just a different way of doing things, I'm sure I'll like it once I learn it.
As a OCF Member I have to ask, What is the most extreme cooling you have dealt with?(LN2, Phase Change, Water, D-Ice, etc.) LN2, at the benching party in philly last year. We definitely need to get one of those on schedule again. Also, my work has LN2 and D-ice sitting around but I haven't asked if it's ok for me to play with those yet. One day, i'll ask, and it will be awesome if they say yes. fingers crossed.
So, can I have some of your left over gear? Joking, heh heh... Seriously though, got any gear that's collecting dust? Mostly by the time we're ready to part with gear, it's not worth much and is terribly outdated. Or, it's been burned up by pushing too many volts.
What do you do with the old gear? Do you scrap up a functional computer and donate it to a charity, or just proper e-waste recycling? If it's not on my computer or benching station, it's in my closet. And my wife doesn't like the amount of computer stuff in my closet, so I'm sure I'll start looking for some way to recycle stuff soon.
Where does a young grasshopper starts to learn all of these materials wise one? Well, you could get yourself a RHCSA prep book (linked to the one i have and found useful) and go through all of the exercises. The way I learned was basically to set up my own servers, either physical or virtual, at home, and run them. I think FreeBSD, Gentoo, and Slackware were the most beneficial to me in that they don't really make choices for you, so you have to configure things for yourself which forces you to read the documentation and learn. They all have excellent documentation, btw. If you want to go a step further, linux from scratch will really teach you about the operating system from the ground up.
From there, come up with little projects for yourself. Like making a home NAS, setup NFS and Samba shares, install XBMC on a HTPC and hook it up to your tv to stream movies and music. Setup a webserver and owncloud. Stuff like that.
Sorry I'm late but... how old were you when you first starting tinkering with Linux and such? I'd like to be a sysadmin or similar when I finish school so I figured you were the right person to ask. I was 19 when I first made that half life/counterstrike server. I didn't even know what ssh was and it took a good amount of explaining for me to finally understand. The freebsd documentation is amazing and will walk you through just about everything step by step. To get NAT configured I had to use another how to but setting up that server taught me a ton.
Are you an Nvidia or an AMD guy? It's changed several times over the years. I used to be solely Nvidia because of Linux, but AMD has been stepping up their game and getting their drivers usable, so I currently run all AMD.
How much of a PITA is it for you to be HIPAA compliant? It's not really that tough. Luckily there's only a couple projects going on right now that have special needs above and beyond regular security needs.
What do you use for storage? We have a few Jetstor SANs, a couple Promise RAID boxes, and an Equallogic box as our VMWare backend. But our main mass storage is Isilon X200.
Whoops my bad, meant 1.18 not 1.8 it'd be gone if it was 1.8. sorry. I am using a hyper 212 EVO in the standard push configuration. Well 1.18 is too low for 4.4ghz.
Only 4gigs of ram in your rig ? Yeah...I've got 16 in my work PC for running VMs, and 16 in my VM host at home too. I'll probably buy more soon.
Oh ok, what V would I go to? I was able to initially get 4.4 with 1.18 and 0 whea errors, what V would you recommend? This is my first oc btw. Bump it up one step at a time until you are stable. Be methodical about it. You can check out what values other people are getting on hwbot.org.
Ok Ill do that, thanks man, at what V if the errors dont go away should I stop advancing them? Most likely you will want to stay around 1.6v. I'm not very familiar with that chip specifically so I'd check hwbot to see what other people have posted and go by that. Obviously remember that not all chips are the same, so you can't expect to get exactly what other people get.
1.6, that seems a bit high for my 212 EVO, a few days ago I did have it at 1.18 without any WHEA 20 errors. That's why I'm saying take it slow, one step at a time.
What do you think of this quote by Richard J. Schwartz? "The impact of nanotechnology is expected to exceed the impact the electronics revolution has had on our lives." Sounds good to me. I can't wait to see what comes next.
Actually nodes, or are some of them VMs? Physical blade servers as nodes. with 144 GB ram each.
Zfsonlinux in use? No I haven't used zfs at all.
Hey... You're pretty cool. Thanks. You're not too bad yourself.
The answer should be ''i wish i could say the same to you'' I'm not like that.
Just how big is your hpc. Only 18 nodes :/ but its more what I do with it...
How'd you get your nickname. Back when I played CS in the dorm freshman year of college, I used to get killed all the time. So I started calling myself "jack splat", as a play on the nursery rhyme (jack sprat), then shortened it to 'splat' on most of the websites I signed up for.
Describe a SHTF moment at your work place. I can imagine it must be highly stressful being the sole responsible person to keep all that gear running. I definitely have a few and luckily they aren't that bad. One of my first few months, I decided to connect this wireless ap to the network to test it out one morning. As I was being awesome managing the cable to make it look clean, one of the security guards came into the server room and said they had no internet. I looked at our switches and they were all lit up solid. By hooking up the ap, which had spanning tree turned on, I took down the network of the entire building.
Ouch...that's definitely a SHTF moment. glad you came out unscathed. Luckily, all I had to do was unplug it and everything went back to normal. I then set up a spare switch at my desk and played with it before figuring out that STP needed to be disabled on the AP. Now it's been running for over a year without incident.
Would you rather fight 100 duck sized horses or 1 horse sized duck? I'd go for the horse sized duck. Seems like more of a challenge.
U mad? Nah, I'm feeling pretty good today.
