Was Grand Moff Tarkin under Darth Vader's control? In A New Hope, we see Grand Moff Tarkin ordering Darth Vader around. Also, it was . It's uncertain whether he knew .  But considering that Darth Vader was a Sith Lord, and a Jedi before that, are we entirely sure he wasn't secretly controlling Tarkin through a Jedi Sith mind trick? How to use hook_node_presave to change field's value nginx support for .htaccess / rewrite rules? Differences from Apache? Data inconsistency prohibition if a table refers to another via two many-to-many relationships I have following database design (by =&gt; foreign key constraints are depicted):   Company[id] CompanyRealm[id, company_id=>Company.id]many2many  Project[id, company_id=>Company.id] ProjectRealm[id, project_id=>Project.id, company_realm_id=>CompanyRealm.id]many2many   Problem is that provided database design allows inconsistent data. For example:   Company1(id=1) Company2(id=2) CompanyRealm(id=11, company_id=1) Project(id=33, company_id=2) ProjectRealm(id=44, project_id=33, company_realm_id=11)   (Company can have many Realms, Project belong to Company and  may concern any number of company's Realms)  ProjectRealm refers to two different companies:   Company1 (via CompanyRealm); and Company2 (via Project).    Is something wrong with my DB design? If yes - which prescriptions are violated? If no - how to prevent incorrect data insertion (via constraint? trigger with exception?) Splitting file based on size, but make sure that it ends with newline I am able to use the split command successfully to split large file into multiple smaller files. This is being achieved by following command  split -b 1G $temp_path $final_filepath   But only caveat is that these files many times contain last line which is split across 2 files. Is there any way to avoid that using split or any other command ? How to defer variable expansion I was wanting to initialize some strings at the top of my script with variables that have no yet been set, such as:  str1='I went to ${PLACE} and saw ${EVENT}' str2='If you do ${ACTION} you will ${RESULT}'   and then later on PLACE, EVENT, ACTION, and RESULT will be set. I want to then be able to print my strings out with the variables expanded. Is my only option eval? This seems to work:  eval "echo ${str1}"   is this standard? is there a better way to do this? It would be nice to not run eval considering the variables could be anything. Where to download Chrome 32bit? Google has  so on a 32bit Debian machine it's not possible anymore to update the APT repository:  W: Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release  Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)   Also has the .deb file removed from Google servers as it seems.  Is there any alternative .deb download of the last release (46?) available somewhere?  Reason: For an automated Debian build system (debootstrap-based) I urgently need a way to install Google Chrome 32bit v46 (or similar). Switching to another browser (including Chromium) is not a quick enough option for me at the moment.. Whenever I open my files, my hidden files show up. I can hide them but when I open up my files again, they're showing again. How do I make the hidden files invisible permanently? What is the difference between if(CONST==variable) or if(variable==CONST)? When I'm not exploring fresh caves or lands in minecraft, I'm busy trying to find deposits of diamond, gold and iron deep in the earth. So far I've just been digging around just above bedrock on a whim to look for these rare minerals but I've started thinking that I should be taking a more controlled, efficient approach to mining.  What is the optimal mining strategy that yields the most rare minerals while minimizing blocks removed and time spent digging and traveling?  Edit: The existing answers are great for mining, but no one has addressed travel time to and from the mine which is usually ~60 blocks downward and incredibly tedious. Solutions? How disk space is used on Android device? How to sort a Google Sheets Query by a custom ordering I have a table of choir members with a “name” and a “voice type” column. How can I write a query that orders them by decreasing pitch level of the voice type (i.e. soprano > contralto > tenor > bass)?  Is there in the  something similar to ?  I also tried the , but it does not seem to have an option for custom ordering, either. Is the tag info page not available on mobile theme? I was surfing SO on my iPhone, and wanted to see the info (tag-wiki) page for a tag, but didn't find it. Clicking on the tag always leads to the list of question, and there is no other link to the tag wiki. Is it not available on the mobile site? After update, Ubuntu has now become PopOS I'm running Ubuntu 20.04.1 LTS. I was recently prompted to install an update from Ubuntu's GUI software updater, but I'm not sure which update. Now, I seem to have... a strange amalgamation of Ubuntu and PopOS all of a sudden? After booting up today, my desktop looks quite different:  It appears to be using Pop Shell, the tiling window manager that PopOS uses. The left-hand dock is gone. Looking at 'Appearance -&gt; Background' in Settings, the PopOS wallpapers are present. If I go to 'Appearance -&gt; Appearance', the light/dark theme chooser shows a visual with &quot;Pop!_OS User&quot; in it. The scrolling direction has been reversed. The icons are different. The Ubuntu Software Center is missing, but there's no &quot;Pop Shop&quot; in its place. The list goes on...  At the same time, a lot of my system is still very much how it was a few days ago when it was &quot;pure Ubuntu&quot; so to speak. My browser, IDE, files/folders, etc. are all the same... For context, I used to dual boot Windows and PopOS on a single SSD, but I've since wiped the drives I use (including resetting partitions). Now I use Windows on the SSD and Ubuntu on a new second drive... I can't imagine how anything from my old PopOS installation would carry over, let alone suddenly reappear inside Ubuntu after an update. EDIT: When running Software Updater again, it shows a full list of what it's trying to install: . When I try to install these packages, it fails midway through. That partially explains things... but why is this even happening? EDIT2: It is trying to install pop-gnome-initial-setup.deb which seems to conflict with gnome-initial-setup. Weird. Why is foo.hasOwnProperty('__proto__') equal to false? I'm having a lot of trouble figuring this one out.  Determine if  $\sum_{i=2}^{\infty} \frac{(-1)^n}{n+(-1)^n}$ converges or diverges  Both ratio and root test are inconclusive and I'm at a loss. Can anyone help me? Windows 10 non-persistent installation (live ISO) We've got a Windows 10 installation running in an environment where it can occasionally lose power and restart. However, this sometimes leads to corruption of files.  I've had a look at Windows "To-Go" but this seems to be persistent. And I've also checked out virtualisation, but that would require us to run a non-persistent Windows 10, in another Windows 10 environment.  Is it possible to install Windows 10 as a "non-persistent live CD"? So that a user will have a seemingly fresh Windows 10, but doesn't require to re-install it at each startup? "My wife and I's seafood collaboration dinner" Creating a default preamble Since I am using (almost) the same set up for my tex documents, I wonder if there is a way to create a preamble with my default packages and to recall it anytime I want to create a tex document.  If yes, how I can call this "default" preamble?  Thanks in advance Remove password from an Excel Document I'm providing internal support and one of our users has managed to put a password on an excel file by accident, I've done the proper checks to make sure that the user should have access to the document and now want to know what the recommendation for removing a password from an Excel document.  For what its worth, the password appears after Excel opens but before you can see any data in excel.
