I recently heard about some vulnerability in older versions of OpenSSL i.e. before 1.1.1i . I checked my servers and found that most have either 1.1.0l or 1.1.1f . The recommended update version was 1.1.1i . Checked for Ubuntu DEB packages for 1.1.1i and found no mention in Ubuntu site. In Debian site the versions 1.1.1i-1 is in Testing and 1.1.1i-2 is in Unstable Stage. Found there is an official TAR package from OpenSSL  If I install the TAR file should it cause problems for any other ubuntu software dependent on OpenSSL ubuntu package? I know that by installing the TAR file I have to handle future update/upgrades manually. Should I install or upgrade 1.1.1i from the TAR file only or wait for Ubuntu to release the update for 1.1.1i?
I just read a description of CVE-2020-1971, which indicates that a patch was released today for openSSL, the patched version is 1.1.1i -- my version of Ubuntu 20.04.1 LTS is running openSSL version 1.1.1f.  From last March. Software Updater says that my system is up to date.  I am hoping that this openSSL update is released by Canonical by tomorrow... can anyone confirm they are working on this?
LaTeX/BibTex not arranging citations by order of appearance "Least Astonishment" and the Mutable Default Argument deleting windows system folder I want to use an old drive as a secondary hard drive without reformatting. But this old hard drive contains my old Vista installation which takes up gigs of space.  I tried changing ownership and it works to some extent but I can not delete anything in Windows/System32 folder.  Is there an easy way to change permissions so I can delete everything?    The solution is to use Takeown as Wil suggested and use cacls to take full control of the files. Since cacls doesn't seem to be recursive, I fired up cygwin and ran this command to recursively change all the files:  for d in $(find directory-of-interest -type d);do   cacls $d'/*' /e /G username:F; done   where directory-of-interest is in my case /cygdrive/g/Windows and username is my username.  I had to manually run it on directories that had spaces in its name. But after all this, I can now delete the directory. Warning: it seems to me that cacls can potentially royally screw things up if improperly used. "put X down to" vs. "put down X to": subjects of verbs with two particles I expect I would have to put down many coats to do the job. ()   One factor to distinguish phrasal verbs from prepositional verbs is particle movement. Phrasal verbs can place the particle before or after direct object, whereas the preposition in prepositional verbs must precede the noun. (Biber et al. 1999)    So, I'm confused when analyzing the fragment "put down many coats to" because I'm not able to distinguish whether "put ... " is a phrasal verb or a prepositional verb. The confusion arises when I read in the Oxford Dictionary of English, under 'put' &rarr; 'phrasal verb', the form "put something down to" is correct.  So, the above sentence would be rewritten as follows :     I expect I would have to put many coats down to do the job.   Am I right? If not, how do I correctly distinguish phrasal verbs from prepositional verbs in the cases, like this one, where there are two particles (in this case 'down' and 'to')?

Adding CSS Reference on Site Page So I have created a Site Page that has the "New Experience" look and I would like to change its style a little. Nothing major, just the height, width, color, etc. However, I can not seem to figure it out.   For example, I tried to change the height of the .pageHeader to a smaller value.   .pageHeader{ height: 150px !important } //for example of CSS in file   Here is a reference image of the page i'm trying to change    I tried adding   &lt;link href="../SiteAssets/file.css" rel="stylesheet" type="text/css"&gt;   to the .aspx page using SharePoint Designer and it didn't work.    I also tried adding   &lt;SharePoint:CssRegistration ID="CssRegistration" Name="SiteAssets/file.css" runat="server" /&gt;   to the .aspx page and it didn't work    I tried to use the "Embed" feature to add the CSS; however, it complains and says,     This embed code doesn't seem to work. We only support iframe based embeds.   Question:   How can I add custom CSS to this type page?  I can't seem to figure it out and I'm not sure exactly why the page will not load the file.  Is this even possible? How does one find which files are taking up 80% of the space on a Linux webserver? The drive is constantly filling up. You've hunted down all the spare and random files you can. grep'd for coredump files and even removed some of the un-needed backups...  What would be your next move.  The actual server in question has 10GB of website files and the OS shouldn't take any more than 10GB so how do you track down what's filling a 50GB (virtual) drive? I'm currently trying to configure our exchange 2010 to be used as a external smtp relay. What I'm trying to do is allow certain websites that we manage to send email using our exchange server smtp relay. I was told that I needed to created a receiver connector under Server Configuration>Hub Transport. After I created the receiver connector I added the following confi in which I added the website IP address in the "Receiver mail from remote servers ect" then unders Authentication I selected Externally Secured,TLS and under permissions I selected exchange servers.   I went to one of our websites and configure it with this configuration and I'm still getting "SMTP connect failed."  Can someone help me? or what is the  proper way to get this to work. Multiple websites are going to be using this exchanger server SMTP relay in a secure way. How to input open intervals I want to write open and half-open intervals using the following notation:  ]a, b[ ]a, b] ]-∞, b]   When writing them just like that in the LaTeX source, the spacing doesn't come out right. For example, for this equation:   \(X = ]-\frac{π}{2}, +\frac{π}{2}[\)   the minus sign is typeset as a binary operator. I can solve this by surrounding the whole value in braces, but then the spacing around the equal sign is still not correct. For other combinations of intervals and operators, different spacing inconsistencies arise.  What is the correct and easy  way to input intervals in order to avoid having to take care of this at all? If just a single photon hit a single slit interferometer, what would happen? Would you just see a dot on the screen, or would there be a diffraction pattern? Furthermore, if you had a double slit interferometer but also had which-path information would there still be a diffraction pattern even though there is no interference? Java is the key here. I need to be able to delete files but users expect to be able to "undelete" from the recycle bin.  As far as I can tell this isn't possible.  Anyone know otherwise?

I have recently installed a custom ROM and cannot find the Play Store. It seems like all apps that belong to Google are missing.  How can I install the Google Apps Package (Play Store, ...) on my Android device? Is it possible to open directories as administrator? I want to have a root privileges on some directories. How can I do this? Why ZSH ends a line with a highlighted percent symbol? I've noticed this on occasion with a variety of applications. I've often thought it was because the output was cancelled early (ctrl+c, for example) or something similar, and zsh is filling in a new line character. But now curiosity has gotten the best of me, since it doesn't seem to do this in bash.   zsh    bash    The Sequence program is something I pulled from a book while reading on Java certifications and just wanted to see if it would compile and run. I did notice that it does not use the println() method from the System.out package/class. Instead it uses plain old print().  Is the lack of a new line character the reason I get this symbol? I'd like to run a game of , but I'm not sure how many dice I roll when the characters face various challenges. I'm under the impression that it's supposed to be the same number of dice the character uses, but that seems to make impossible tasks far too easy to perform. Is there a general rule saying how many dice the GM rolls against a character's attempt at a given task?  Should the GM's dice equal the character's dice, or should the GM's dice vary depending on the task's difficulty? Light "diode" and 2nd law of thermodynamics If I had a light "diode" - an object that only allowed light (at least for a range of frequencies) to travel through it in one direction, would this necessarily allow violations of the 2nd Law of Thermodynamics?  Or would it be possible to restrict other properties of the device such that it could be okay.  Why I think it should violate 2nd law:   I can place such devices at temperature T in a bath of thermal radiation at temperature T, such that it forms a box which only lets the light in or out.  This would appear to always allow one to create a thermal gradient.  Once a thermal gradient is formed, useful energy can be extracted.  This seems to allow useful energy to always be extracted from a thermal bath and thus give perpetual motion. Release one such device at temperature T in a bath of thermal radiation at temperature T.  Since the photons are absorbed or reflected in one direction, and undisturbed in the other, the device will start moving.  It can use a thermal bath to directly generate useful motion.   Why I think I'm missing something and such a device could potentially co-exist with the 2nd Law:   The above arguments seem valid if the diode was only 'partially' rectifying as well.  However there exist sunglasses which largely reflect on one side, but not from the other side. Researchers have succeeded in using meta-materials to create a "blackhole" for microwaves.   Can anyone help sort this out? Revert new tab page behavior in Google Chrome 29+ I don’t like the behavior of the new tab page in Google Chrome 29+. How can I restore the old behavior?  The new tab page (if you have Google set as the default search engine) now shows the Google logo (or, apparently, the doodle of the day if there is one), a search box, and a few recently visited websites. It also added an Apps button to my favorites bar, seemingly the only way to access my apps page, which has easy access to things I use regularly (Calendar, Gmail, Docs, G+, Facebook, Feedly, Google News, Netflix, Play Music, Pandora, Drive, Keep, etc.) I don’t like this behavior. I actually don’t mind having the logo of the day and search box, but I want my apps linked to on my new tab page.  Is there any way to get the old behavior back? I checked the settings and it doesn’t seem like it’s possible to set chrome://apps to be the new tab page (which would restore the old behavior) or to configure the new new tab page to display apps instead of recently visited sites. Am I Running as a Service I am currently writing a little bootstrap code for a service that can be run in the console. It essentially boils down to calling the OnStart() method instead of using the ServiceBase to start and stop the service (because it doesn't run the application if it isn't installed as a service and makes debugging a nightmare).  Right now I am using Debugger.IsAttached to determine if I should use ServiceBase.Run or [service].OnStart, but I know that isn't the best idea because some times end users want to run the service in a console (to see the output etc. realtime).  Any ideas on how I could determine if the Windows service controller started 'me', or if the user started 'me' in the console? Apparantly  is not the answer. I thought about using commandline args, but that seems 'dirty'.  I could always see about a try-catch statement around ServiceBase.Run, but that seems dirty. Edit: Try catch doesn't work.  I have a solution: putting it up here for all the other interested stackers:      public void Run()     {         if (Debugger.IsAttached || Environment.GetCommandLineArgs().Contains&lt;string&gt;("-console"))         {             RunAllServices();         }         else         {             try             {                 string temp = Console.Title;                 ServiceBase.Run((ServiceBase[])ComponentsToRun);             }             catch             {                 RunAllServices();             }         }     } // void Run      private void RunAllServices()     {         foreach (ConsoleService component in ComponentsToRun)         {             component.Start();         }         WaitForCTRLC();         foreach (ConsoleService component in ComponentsToRun)         {             component.Stop();         }     }   EDIT: There was another question on StackOverflow where the guy had problems with the Environment.CurrentDirectory being "C:\Windows\System32" looks like that may be the answer. I will test today. Should Stack Exchange introduce the ability to upload embedded sounds (maybe via HTML5/Flash, whichever the user has) as part of questions and answers to Stack Exchange?  It could require a certain amount of rep to stop new users from doing it frivolously.  My rationale behind this is the new language &amp; usage sites.  I often find myself thinking that it might be helpful, when discussing a regional dialect or something, for the person answering to just pronounce what they're trying to describe in words.
