Despite following  for .jar file :   java -jar imker-cli.jar   It doesn't work for me :   me@pc:~/Documents/imker$   java -jar imker-cli.jar The program 'java' can be found in the following packages:  * default-jre  * openjdk-8-jre-headless  * gcj-4.8-jre-headless  * gcj-4.9-jre-headless  * gcj-5-jre-headless  * gcj-6-jre-headless  * openjdk-9-jre-headless Try: sudo apt install &lt;selected package&gt;   What is going on ? What should I do to run this .jar file ?
I know that to execute a file, I use the . command, then the file name with a space between them. But I'm trying to execute a .jar file using the . and it does not work. I went into the properties and marked it as executable and made it run with Java.   Is there a way to execute a file with Java in the Bash Terminal?    I am trying to execute the Minecraft.jar file.
Is it true that an ideal is primary iff its radical is prime? Let $(a_n)_{n}\in\ell^2:=\ell^2(\mathbb{R})$ be a fixed sequence. Consider the subspace $$C=\{(x_n)_{n}\in\ell^2 : |x_n|\le a_n\text{ for all }n\in\mathbb{N}\}.$$  According to the book [Dunford and Schwartz, Linear operators part I, page 453] $C$ is compact in the $\ell^2$-norm, but there is no proof. How can I show that $C$ is indeed compact in $\ell^2$ ? How do they decide Blu-ray/DVD release date? Does deleting iCloud photos affect them on devices?

We have created a logo for a client and they love it. We've already started preparing the materials that will feature the new logo.   However, after we had created the logo, we found a logo for another company that looks eerily similar. We did not intentionally create the new logo to look like the one of the other company, in fact we didn't even know it existed beforehand, but it does regardless.  What should we do? Is this plagiarism? Can our client use the logo we have created? Should they? Or do we need to come up with another logo that's more different?

I know that it is common to write the number 'ten thousand' as a numeral with a comma delimiting the 10 and the 000 like so: 10, 000  However, I have never seen a comma used for numbers less than 10,000, such as 8000 where, I assume using a comma would look like: 8,000.  Are there any rules relating to when a comma should be inserted into a numeral?  N.b. I live in the UK, so answers pertaining to UK English are preferred. I am writing a client-side Swing application (graphical font designer) on Java 5. Recently, I am running into java.lang.OutOfMemoryError: Java heap space error because I am not being conservative on memory usage. The user can open unlimited number of files, and the program keeps the opened objects in the memory. After a quick research I found  and others saying on Windows machine the JVM defaults max heap size as 64MB.  Given this situation, how should I deal with this constraint?  I could increase the max heap size using command line option to java, but that would require figuring out available RAM and writing some launching program or script. Besides, increasing to some finite max does not ultimately get rid of the issue.  I could rewrite some of my code to persist objects to file system frequently (using database is the same thing) to free up the memory. It could work, but it's probably a lot work too.  If you could point me to details of above ideas or some alternatives like automatic virtual memory, extending heap size dynamically, that will be great.

This can sometimes be quite slow and Outlook hangs while this is done.

(e.g., Outlook 2007) I've had a promising Skype interview with a great professor from a top-level university in US. Our research interests are closely related and he encouraged me to apply BUT he says that all decisions are finally made by admission committee there.  The question is "Is a professor in such a high-level university able to affect admission committee if he really wants a student?" or "Does admission committee decision-making process become easier if a professor really wants an applicant?"  The main point is the difference between my transcript (which is a real catastrophe!) and my research background which is pretty good so the professor's decision might be different from admission committee. Appropriate statistical analysis to use How does Lockable Suspension work? I recently asked a question about . There  told me about the “blow off” feature.
