I am trying to download QGIS 1.8 on my windows operating system. When I tried to launch QGIS 1.8 a dialog box appears, preventing me from launching the software. This is the error that is generated:    I don’t know what this error message mean or how to fix it.
I note that the installation of qgis completed successfully. However, the log procedure returns this message:     "......

Do you capitalize both parts of a hyphenated word in a title? Do you capitalize both parts of a hyphenated word in a title?  "My Ex-Wife Hates Me"  or  "My Ex-wife Hates Me" No Dropbox top panel icon since update to 18.04 "Is there" versus "Are there" Are there any questions I should be asking?   Is there any articles available on the subject?   My instinct is that in the two questions above, it should be 'are' as the subjects of the sentences (questions/articles) are plural.  However I also recall being told that the singular 'is' is valid here too, and of course see it very often in usage online, and this has left me a bit unsure.  Update: I have stumbled upon the reason for the confusion.     Is there any water?   Are there any questions?   The sentence structure is the same but of course water is not plural, although it is not singular either. If I have a Xaml Window, how does one open it as a child window, and then have the parent window wait for the child to close before the parent window continues executing? Say, we have a query like this:  select a.*,b.* from  a join b on a.col1=b.col1 and len(a.col1)=10   Assuming the above query uses a Hash Join and has a residual, the probe key will be col1 and the residual will be len(a.col1)=10.  But while going through another example, I could see both the probe and the residual to be the same column. Below is an elaboration on what I am trying to say:  Query:  select * from T1 join T2 on T1.a = T2.a    Execution plan, with probe and residual highlighted:         Test data:    create table T1 (a int, b int, x char(200)) create table T2 (a int, b int, x char(200))  set nocount on declare @i int set @i = 0 while @i &lt; 1000   begin       insert T1 values (@i * 2, @i * 5, @i)     set @i = @i + 1   end  declare @i int set @i = 0 while @i &lt; 10000   begin     insert T2 values (@i * 3, @i * 7, @i)     set @i = @i + 1   end   Question:    How can a probe and a residual be the same column? Why can't SQL Server use the probe column only? Why does it have to use the same column as a residual to filter rows again?  References for test data: Is it grammatical to omit the subject from "I did my work"? Add a duplicate:0|1 search operator I often search for closed questions and sift through the ones that are not duplicates to see if any of them need to be killed. Technically, closure is the first step towards deletion and the only closed posts that are actually useful are duplicates (unless it's a crappy one).  For the rest, if the community hasn't bothered to reopen it after a while or if the OP has made no effort to edit their question, I delete it if it has no redeeming content. For example, the only closed posts seen on  are exact dupes.  But this does become tedious when there are several results for various close reasons with duplicates interspersed between them. I'd like to be able to search as:  closed:1 duplicate:0   so that it gives a list of questions closed as OT/NaRQ/NC/TL. This will be similar in behaviour to migrated:0|1.   This will also be useful for 10k+ users on all sites (2k+ in beta) in the network, especially SO, so that they can search for questions to spend their delete votes on— especially closed, non-dupe questions in the tag they specialize in. More often than not, I hesitate to vote on questions that are outside my area of interest (unless it is crappy). I would like footnote numbering to continue over pages and chapters. In my document it's reset every chapter. I'm using the report documentclass. How to move apps from internal to external storage? I try to clean my mid-2015 Macbook Pro with Retina display by wiping the screen with a damp cloth and then immediately drying.  However, there seems to be left some residue/streak marks, which look very oily. Sometimes these disappear after a few minutes, but they are still very unsightly, and a bit worrying (is there something wrong with my screen?)  I'm wondering if there are other cleaning techniques which avoid this issue, or whether this is completely normal behaviour.  Thank you! I am using the  for GNOME Shell, similar to the old Maximus extension for GNOME 2 / Unity. When I maximise a window, the title and menu bars are hidden.  But I don't want the minimise, maximise or close buttons to appear in the Activity Bar. , so I have been able to remove the minimise and maximise buttons by disabling them in Tweak Tool.  How do I similarly disable/remove the close (X) button?  (I guess this is the opposite of ) Linear vs nonlinear differential equation How to distinguish linear differential equations from nonlinear ones? I know, that e.g.: $$ y''-2y = \ln(x) $$ is linear, but $$ 3+ yy'= x - y $$ is nonlinear. Why? Tempdb Add files require Restart Does adding Tempdb files require a restart? We would like to Add files on the same drive, Not Delete and Not modify. We tested in Dev and QA environment, restart was not required. However for production I would like to be sure everything works properly. Some are stating conditions, not always necessary, sometimes necessary, I am reading resources below:  ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev2', FILENAME = N'G:\tempdb2.ndf' , SIZE = 12288000KB , MAXSIZE = UNLIMITED, FILEGROWTH = 0 ) GO ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev3', FILENAME = N'G:\tempdb3.ndf' , SIZE = 12288000KB , MAXSIZE = UNLIMITED, FILEGROWTH = 0    Do You Need an Outage to Add tempdb files? Brent Ozar  "Technically, not always. But practically speaking, yes. If you have to shrink files, that’s very difficult while SQL Server is in use, and we’ve seen cases where anti-virus/file control tools didn’t act up until SQL Server was restarted after the files were added."   "Once the additional files have been created, it’s not always necessary to perform a service restart.  However, in many production environments, simply modifying the filesize of the existing TempDB datafile (tempdev) is not possible without restarting services first. "  The following resources are saying no restart required: I understand that the vibration modes of an elementary string determines the identity of its particle. When I first heard this, I visualized a stiff circular steel band-like entity vibrating with 2, 3, 4, 5,... nodes or antinodes, the number determining the particle. This was further supported when I asked a well-known physicist how one gets from equations to physical strings, and he said he recognized the harmonic nature of the solutions.  Bu then I noticed that physicists seem to accept the image of a soft spaghetti-like string flopping about with no well-defined vibrational modes. I asked another physicist about this, and his answer was simply that a string has multiple modes, not necessarily in a harmonic progression.  So my questions are 1) How do you visualize the vibrations of a string, and 2) how are they related to particle identity? What does accepting an answer actually convey (2015 edition)? Unsung hero dilemma This is partly related to  question.  I ran some queries on odata for my work on Stack Overflow, and I have found that my statistics are the following ones:  Accepted answers: 148 Zero score accepted answers: 36 Percentage of total: 24,3%  I probably fit the idea of the Unsong hero badge, as I've mostly been active in  questions, from when it only had around 200 Questions until now.  To get the badge I could either try to get one of my accepted answers downvoted once, that would give me a 25% accept rate; I could also delete 4 of my accepted answers with 1 or more score. That would also give me the badge, but this just seems wrong: You are actually encouraging me to either try to get a down-vote on a good answer, or delete good answers.  So, should I delete good answers to receive a gold badge?  Update: It's not that I care much if I get a badge or not, it's only a badge after all and not why I spend time on Stackoverflow anyways. But it's not ideal [read: problem] that I'm encouraged to delete accepted answers or try to get downvotes to achieve a badge. How do you get the index of the current iteration of a foreach loop? How to block and unblock https access on OS X 10.9 I am working on a test project that requires me to block https access for a specific app on my Mac (OS X 10.9).   The instruction provided are "Chinese" to me and I have no idea where to start:  (Example: Alter the iptables) Steps:   Block the port:  root@QA9:/opt/appname/appnamerouter2# iptables --list root@QA9:/opt/appname/appnamerouter2# iptables -A INPUT -p tcp --destination-port 443/8443 -j DROP root@QA9:/opt/appname/appnamerouter2# iptables --list  For Open the Port:  root@QA9:/opt/appname/appnamerouter2# iptables -D INPUT 1 Can PHP PDO Statements accept the table or column name as parameter? Why can't I pass the table name to a prepared PDO statement?  $stmt = $dbh-&gt;prepare('SELECT * FROM :table WHERE 1'); if ($stmt-&gt;execute(array(':table' =&gt; 'users'))) {     var_dump($stmt-&gt;fetchAll()); }   Is there another safe way to insert a table name into a SQL query? With safe, I mean that I don't want to do  $sql = "SELECT * FROM $table WHERE 1" Thousands of .log files in Exchange 2007 Server folder I'm a bit of an Exchange admin noob so I don't know if this is normal, but on our Exchange 2007 server under C:\Program Files\Microsoft\Exchange Server\Mailbox\First Storage Group\ there are 30,000 1MB .log files.  I don't know if those should be there or not, but they keep multiplying like little jackrabbits.  I've so far resisted deleting them as I'm sure something would break, but it's come to the point now where our 80GB disk is completely full up and Exchange has stopped receiving messages.  My best guess is that these are transaction logs and would be useful in rebuilding the database should something go awry, but 30GB of transaction logging seems a bit excessive.  Is there a way to limit it or is that even a good idea?  And of course did I completely miss the point?
