I have an old Alienware computer that I found in storage. It has Ubuntu 11.04 installed on it and I really would like to update to the most recent Ubuntu.  I am not Computer savvy when it comes to terminals and commands.  I don't know what to do.  All I want is to have my son able to watch Youtube but Flash won't install.  Nothing will install, I keep getting Fetch errors or failed to fetch.  I can't download Chrome website, because it says check Internet... Internet is fine. I don't understand what is going on or how to fix it?
What are the different ways I can use to upgrade Ubuntu from one release to another?
openSuse, new user cannot login I am using openSuse 12.3.  I have created a new user using:  linux-amvn:~ # useradd -m -G users,dev -s /bin/bash -p pass123 harbir-PC   The user harbir-PC is not able to login, when I try to log using ssh. I went ahead and looked into the /etc/passwd file and I see the following:  harbir:x:1000:100:harbir:/home/harbir:/bin/bash kdm:x:489:487:KDM Display Manager daemon:/var/lib/kdm:/bin/false harbir-PC:x:1001:100::/home/harbir-PC:/bin/bash   There is a difference between the user harbir and harbir-PC.  I have no problem with the user harbir (who I have created during installation), but I need to login using the user harbir-PC.  I also checked the /etc/shadow, and passwords are encrypted. 155 GB in c drive used up. 50 GB used in minutes. Windows 7 My laptop has Windows 7 home premium. OS is installed on C drive. The C drive has some 155 GB but currently only 1.17 GB is free. I deleted contents of my download folder and moved the contents from my desktop and my documents. this freed some 50 GB. but within minutes it was full again. ran disk cleanup and gained some 2 GB. i checked size of all the folders ignored large sized windows and program files and program files (x86). Was baffled when users folder said 110 GB. went to my user folder and selected all files n checked properties it showed under 5 GB. So if i check my user folders properties it says 110 GB but if i check properties of its content its under 5 GB. BTW I am not using any anti virus program. Do you guys have any idea whats going on. Is my laptop possessed or something? :P Please help me out. How do I change the mode of perspective? I'm working on a scene that, currently, is much more convenient when the view is.. not the correct perspective. There's a word for this, but I have no idea how to phrase it and my tries to look it up has all come up with weird results. (usually directions on how to make your view point from a certain direction) This has probably already been answered here, so please bear with me; I just cannot find anything that has to do with the problem I'm having. I drew a photo to make it easy: (excuse my crappy mouse-drawing skills)  Thanks! How can this English sentence be translated into a logical expression? ( Translating " unless") You cannot ride the roller coaster if you are under 4 feet tall unless you are older than 16 years old.   Let:   $P$ stands for "you can ride the roller coaster" $Q$ stands for "you are under 4 feet tall" $R$ stands for "you are older than 16 years old"   Is this logical expression correctly translated?  $$P \rightarrow (Q \wedge R)$$ How would you cut a shape out of an object using another object? Is stack.imgur currently down? I just wrote a question before this one and had trouble uploading a screenshot. The drop your image dialog throws no warning or error, but after uploading it won't show.  I also noticed that other questions won't load their images. Could this be some issue with imgur or similar?  Example:     When opening the image in a separate tab, Chrome gives a "too many redirects" error:    This might be linked to What are irreducibles in the ring $R$ of entire functions? How to handle UNABLE_LOCK_ROW errors when this is caused by a batch APEX job we are facing a serious issue. We have a batch APEX job running daily which makes updates on records fulfilling certain conditions. There is another job running parallel to this, in some cases updating or accessing to the same records than the batch job and hence, causing the error:     Update failed. First exception on row 400 with id XXX; first error:    UNABLE_TO_LOCK_ROW, unable to obtain exclusive access to this record or 200    records:   So, I had then read that in order to fix this kind of error you should use FOR_UPDATE in your select statement (records that have to be updated). The problem is, that you can not use FOR UPDATE for batch jobs. We tested this and effectively, we get the error:     System.QueryException: Locking is implied for each batch execution and   therefore FOR UPDATE should not be specified      It will however lock the records within each execution of execute. See   QueryLocator.getQuery()usage:      You cannot use the FOR UPDATE keywords with a getQueryLocator query to   lock  a set of records. The start method automatically locks the set   of records in  the batch.   Could you find a solution to this?. We would like to handle this in the code itself, because we don't have the permission to schedule the batch job for another time as the another job. Site Analytics header does not show the link to "traffic sources" when in that section I was seeing the Site Analytics page (/site-analytics)  (>25K users) and also  and found out that the header is not consistent:   When in history, the header shows "history | traffic sources" When in traffic sources, the header just shows "history"   Graphically: I used a website called Seeking Arrangements and met a  sugar daddy. He asked for my email login, online banking login, routing, account number, Facebook, as well as my  address which is the only thing I gave him since it’s a PO. I’ve been extremely vague just to see if this is real.   I don’t plan to give him anything because I have only been talking to him for a few months and  I feel conflicted. I doubt that he is trying to scam me but I suspect that he has some kind of master plan. With things such as Venmo, Zelle, and Cashapp, what is the need for “put me on his payroll?”   He claims that he is in another country on a business trip.  He said that  he tried to send me a gift but he lost access to his card. He is now asking to deposit more than 10k into my account and have me wire it. Is this a l classic way of scamming people? If so, is it common that they spend months creating a relationship with you  to catfish you? Can you change your email for Pokemon Go? Where should I start learning? There are various topics to learn like Objects, Classes, Apex, Visualforce, SOSL, SOQL, Triggers, etc. There are so many options out there to start learning. I couldn't decide what topic to learn first, and then step by step get proficiency in all aspects of Saleforce. gedit: search and replace with regular expressions I want to replace this with gedit:   1299465 |  2003415 | 2015-09-06 05:35:34.59662+02  1299449 |  2009400 | 2015-09-06 05:35:32.301683+02  1299450 |  2008465 | 2015-09-06 05:35:32.451393+02  1299457 |  2015211 | 2015-09-06 05:35:33.451049+02   to that:  2003415 2009400 2008465 2015211   How can I do this with gedit?  Background: I want to do it with gedit and not sed/python/.... since the replace needs to be done interactive. What's in a name: hyperparameters So in a normal distribution, we have two parameters: mean $\mu$ and variance $\sigma^2$. In the book Pattern Recognition and Machine Learning, there suddenly appears a hyperparameter $\lambda$ in the  regularization terms of the error function.  What are hyperparameters? Why are they named as such? And how are they intuitively different from parameters in general? MySQL 5.5.16 allows anonymous connections Apparently, I can connect to MySQL (at least from my localhost) without having to provide any username or password. I can even put anything as username, as long as the password is empty. I have access to the information_schema and test databases. I can create tables. If I run SELECT USER() it returns the proper value randomstring@localhost, where the random string is whatever I used for username when I connected.  The mysql.user table contains root@localhost, root@127.0.0.1, @localhost and pma@localhost. I manually set encrypted passwords to all the records (UPDATE user SET password=...) and only root has any privileges, the other two records have "N" for all privileges. That record with the empty username looks suspicious, but I don't think it has anything to do with this and I think it was there from the beginning.  To make matters worse, if I add a user with a password, I can only connect using empty string as password (just like if I put anything as username). If I try to connect using the username I created and password I supplied when creating it (CREATE USER .. IDENTIFIED BY ..) it doesn't work.  Does anyone know what is wrong and how I can fix this?  Note: I am using MySQL 5.5.16 for Windows, provided by the XAMPP package.

Using Regular Expressions to Extract a Value in Java I have several strings in the rough form:  [some text] [some number] [some more text]   I want to extract the text in [some number] using the Java Regex classes.  I know roughly what regular expression I want to use (though all suggestions are welcome). What I'm really interested in are the Java calls to take the regex string and use it on the source data to produce the value of [some number].  EDIT: I should add that I'm only interested in a single [some number] (basically, the first instance). The source strings are short and I'm not going to be looking for multiple occurrences of [some number].
