I have a laptop, a desktop, and a spare 5' Ethernet cable that I can use to directly connect one to the other. The desktop freezes every few days or so, seemingly at random, and when it happens I want to be able to ssh into it as mentioned  so I can make a proper bug report and get this fixed.  Unfortunately, the linked guide doesn't give any instructions on how to do this. Can someone provide a step-by-step answer on how to ssh from my laptop into my desktop when the latter freezes, and also how to conveniently retrieve the necessary files once logged in to attach to the bug report?  A couple things to keep in mind:   I'm using standard desktop Ubuntu installs on both systems. If there's any extra packages I need installed beforehand, let me know. My machines each have only a single Ethernet port; the desktop uses this for its wired-only Internet connection, and my laptop on the other hand uses an 802.11n WiFi connection. Only one machine can use the wired connection at a time due to network restrictions in my dorm, and the wireless connection my laptop uses is very unreliable. Thus, answers should preferably not depend on a working Internet connection, but rather a direct connection between the two machines, if that's possible. I've never logged into one of my own machines from another of my own before, so assume I know nothing and be sure to provide plenty of details. :)
How can I network two Ubuntu computers, so that they can "see" each other at an IP address?
How to Install Virtualbox on Windows 10 host? Is "Smaug" pronounced "Smog"? Did Tolkien the linguist intend for the name of the dragon Smaug to be pronounced "Smog" [IPA: /smɒɡ/ or /smɔːɡ/]? The trailer for the second installment of The Hobbit trilogy pronounces the word (pronounced 'sma-ow-g' [IPA: /smaʊɡ/]) entirely differently than the way I have been reading it for all these many years. Real UID, effective UID, and some systems even have a "saved UID". What's the purpose of all these, especially the last one? So I was in the middle of making a ball-shaped smoke, but the volumetric effect didn't work following the basic shape. It remains cube in Eevee Blender 2.8; while in Cycle it works, but in Cycle it takes thousands of years for Render. How do i find nichrome temperature I am creating an ZIP file with ZipFile in Python 2.5, it works ok so far:  import zipfile, os  locfile = "test.txt" loczip = os.path.splitext (locfile)[0] + ".zip" zip = zipfile.ZipFile (loczip, "w") zip.write (locfile) zip.close()   but I couldn't find how to encrypt the files in the ZIP file. I could use system and call PKZIP -s, but I suppose there must be a more "Pythonic" way.  I'm looking for an open source solution. Why is vote time missing in the SE data dump and SEDE? Is there a particular reason why vote times are omitted in the data dump?  IMO this could be a very useful data-set. Is this one of the steps that was done to anonymize the data, or does it simply not exist? This would be a very good addition to future dumps to help build time-based relationships, which are currently very rigid and full of assumptions. Number of suggested edits seems to include own edits On the new History beta site I have the privilege to approve tag edits already but my own edits still go into the review queue. And the review dashboard displays a different number of pending edits depending on where I am: on  I see one pending edit, on  I see none. I am pretty sure that the pending edit being displayed is my own - I edited a tag wiki and that edit hasn't been approved yet. It shouldn't be counted no matter where I am.

Plz, explain the steps.... Using bools in calculations to avoid branches I want to georeference jpg map without any digitizing data I had a Minecraft world on Minefold.  I archived my Minecraft world just before Minefold closed about a year ago.  I'm trying now to open the world in my local Minecraft installation on OS X, but it doesn't show up in the worlds list.  To import it, I simply unzipped the archive from Minefold into my ~/Library/Application Support/minecraft/saves folder.  I'm running Minecraft 1.8, and I don't have any mods installed.  There's no error; the world just doesn't show up in my list of worlds after I click [Singleplayer] (or [Multiplayer]).  Now, the big clue is that the directory structures are different between my locally-created worlds and the world created on Minefold, but I can't figure out how to adapt the files to make them match:  This is a screenshot of my saves folder. I've circled in blue "local" and "minefold", which contain data files for the local and Minefold worlds, respectively.    I bracketed similar filenames in both worlds, but I'm flummoxed in that the Minefold version has three (3) sets of data files, whereas the local world has only one (1) set of files (even though I have visited Nether in the local world).  How do I load my old Minefold world locally? Why do investors pay trillions for minority stakes in companies, when their only potential payback is modest uncertain dividends? I'm struggling to understand the core reason to invest in stocks as a minority shareholder. Majority shareholding makes more sense as you effectively control the company, so you can pay yourself dividends or even sell the entire company at will. You can guarantee your own payback.  However, as a minority shareholder, you don't get to make any of these decisions. You're basically just hoping to eventually, some day get paid, if the majority holders decide so.  Why do so many investors agree to pay now huge sums of money (trillions in total) for something that may eventually pay dividends, and even in the best case, these dividends are only a fraction of the price you paid to acquire these stocks?  The average annual dividend rate for the US stock market is 2%. That means if you bought 100 million worth of shares, you'd have to wait 50 years to recover your investment.  Of course, the most probable way you'd eventually get liquidity for these shares is by selling them to some other starry-eyed investor - which makes the whole thing seem like a giant Ponzi scheme.  Given all that, it's unclear to me why the public is willing to spend so much money to acquire minority shares in companies. How to delete Windows.old in Windows 8 It seems to be a common thing that a Windows Update creates a Windows.old folder under C:\Windows.old My question is now, can it be deleted with Windows 8 and how can I do that?  If I try to manually delete it in Windows Explorer it does not let me, a permissions issue. Is there any Stack Exchange site where the main topic is literature?  I have tried the English Language site, but it seems that it is not the appropriate site.  Perhaps the writers site would work? But, then again, the main point is different than the one I am searching for. I have an app installed on my phone, which I've installed from the Google Play Store.  If I update the app and don't like the upgraded version, is there a way to undo the update and downgrade back to the version of the app that I had previously installed?  I tried searching a bunch on this site, and I found lots of questions about downgrading the OS/ROM/firmware, but nothing about downgrading app versions or reverting an app update. How to export data with tab delimiters using Apex Data Loader? The internet vaguely says that this is possible. I need this feature to export translation values from a custom object and then import this back into Salesforce using translation workbench. Translation workbench accepts:   Field delimiter: Tab Character delimiter: None   How can we achieve a tab delimited data export from a custom object using Apex Data Loader? What is the best way to handle a lot of misused tags? So today I noticed a question that had the  tag. As the question was not about JSFiddle, and only included a link to the site, I thought somebody has just created this for the sake of it. So I decided the best action would be to remove it, and try to stop it from getting out of control.  But then I searched (clicked the tag) for other questions that used it and I was amayonaised to see over 500 questions had the very same tag! Most of which were incorrectly tagged. So I cleaned up a couple and then quickly got bored.  So I am wondering, aside from going through them all by myself, is there a more efficient way?  I think it would be a great idea if there was some feature (probably an admin feature) that allowed a new tag queue to be added to the review list. I think this could work well as follows:   Somebody brings up the problematic tag in question (e.g. Me on here) An admin reviews my concern, and decides that the tag is very misused That admin adds the tag for review in a (temporary) new review queue. All users that can review can then go through existing tags, and vote for "No action" or "Remove tag" The world becomes a slightly better place   ...or not?    By the way, I tried to add some new tags to this post but I don't have the rep. So if someone could create them for me that would be swell: "musefan", "today", "sunny-spells", "pointless-tags" Negative probabilities are naturally found in the Wigner function (both the original and its discrete variants), the Klein paradox (where it is an artifact of using a one-particle theory) and the Klein-Gordon equation.  Is a general treatment of such quasi-probability distributions, besides naively using 'legit' probabilistic formulas? For example, is there a theory saying which measurements are allowed, so to screen negative probabilities? Additionally, is there an intuition behind negative probabilities?
