• Converting a C# code to F#??

  - by Brendon

  Hello all I am just a beginner in programing i wish covert some code from C# to F#, I have encotered this code: float[] v1=new float[10]; ... //Enqueue the Execute command. Queue.Execute(kernelVecSum, null, **new long[] { v1.Length }**, null, null); I have previously ask how to convert the v1 object, I think i know how, But how do i use the function call especially the "new long[] { v1.Length }" part of the function argument, what does "new long[] { v1.Length }" mean??

• How to enable 'wget' to download the whole content of HTML with Javascript

  - by neversaint

  I have a site which I want to download using Unix wget. If you look at the source code and content of the file it contain section called SUMMARY. However after issuing a wget command like this: wget -O downdloadedtext.txt http://www.ncbi.nlm.nih.gov/IEB/Research/Acembly/av.cgi?db=mouse&c=gene&a=fiche&l=2610008E11Rik The content of the downdloadedtext.txt is incomplete and different with the source code of that site. For example it doesn't contain SUMMARY section. Is there a correct way to obtain the full content correctly? The reason I ask this because I want to automate the download from different values in that HTML.

• Vim plugin Align fails to work. Can it be installed without vimball?

  - by Leonard

  I've happily installed the vim Align plugin on my home computer, but on the Red Hat servers at work, the installation doesn't work. The servers at work have a very old copy (2006) of vimball, which from Googling I know doesn't support more recent vimballs, including Align. I can't get the systems group (IT department) to upgrade vimball, so I thought perhaps I could simply copy the various files into ~/.vim/plugin by hand. I copied the 3 files from my home system AlignMapsPlugin.vim AlignPlugin.vim cecutil.vim, but when I attempt to use Align from within vim I get the following error message E117: Unknown function: Align#Align I know that it's seeing the plugin, because when I remove the plugin the error message is different (it says "Not an editor command Align"). Is there a workaround for this? I love "Align" and would sure like to use it at work as well as at home.

• How do I stop intellij from adding specific jars to the classpath when debugging?

  - by AlecZorab

  When I debug an application in intellij, it insists on including all the jars in side my jre/lib folder and sub folders. Unfortunately, one of the libraries I use manually loads each class on the classpath at startup to reduce loading times during operation. As a result, debugging my app immediately results in the process spinning at 100% and then eventually dying. If I take the command line intellij uses and remove the jars in the lib folder from the classpath, the application executes as expected. How do I make intellij not include the jre libs?

• Eclipse - Ouline View - Turn Off Filtering

  - by Ibolit

  Hi. I recently installed Eclipse on my new computer, and this installation somewhat filters the class members. I think it is somehow related to the Outline, but i couldn't find any settings related to it. The thing is that when i, for example, have an error in a method, and click on the little red square on the margin, eclipse shows me only that method, and nothing else. When i then click on the class name in the outline panel, eclipse shows me the class without import declarations. I can, of course, click on the import declarations in the outline panel, but then i get only them. When I want to jump to the declaration of some method by command-clicking that method's name, I again get only that method on the screen. It is really annoying. Can anyone please help me fix it? Best regards,Timofey.

  I am using jdbc to connect to a postgresql database in a java application (actually the app is written in Groovy). I have postgresql set up to use the 'trust' authentication method.

• Need help searching a MySQL db using a SELECT DISTINCT result

  - by user1695645

  So I am new to MySQL and am having a bit of trouble. I have one table called book_genres and another called books. book_genres +-------+---------+ |book_id| genre | +-------+---------+ | 1 | Horror | | 1 | Comedy | | 2 | Romance | | 2 | Comedy | +-------+---------+ books +-------+---------+ |book_id| title | +-------+---------+ | 1 | A Book | | 2 | B Book | | 3 | C Book | +-------+---------+ I am using the following command to pull all the book_ids that have 3 selected genres: SELECT DISTINCT a.book_id, b.genre AS genre1, c.genre AS genre2, d.genre AS genre3 FROM book_genres a JOIN book_genres b ON a.book_id = b.book_id AND b.genre LIKE 'Romance' JOIN book_genres c ON a.book_id = c.book_id AND c.genre LIKE 'Action' JOIN book_genres d ON a.book_id = d.book_id AND d.genre LIKE 'Comedy' GROUP BY book_id What I want to do is now pull all of the book titles from the books table using the book_ids found in this search. I'm not sure if there is an easier way to do this or not, but this was all that I could come up with. Thank you for anyone who can help!

• Lua Tables w/ Changing Variables - Mental Block

  - by bottles

  I always assumed that changing the value of k from "x" to 20 would eliminate "x". So why then in this example are we able to go back and reference "x"? a = {} k = "x" a[k] = 10 print(a[k]) ---> Returns 10 print(a["x"]) ---> Returns 10 a[20] = "great" k = 20 print(a[k]) ---> "great" a["x"] = a["x"] + 1 print(a["x"]) --> 11 Why does that last print command work, and return 11? I thought we set k = 20. Why is "x" even in the picture?

• Mac OS X: getting names of changed/written files

  - by Patrick

  I remember having a command line tool on an older Mac OS X version (Tiger?) that told me the name of every file that was written to (or read) by any process on the system. It used fseventd (? or something like that). Is there something like that for the newest Mac OS X (10.6)? It should be run in a terminal window and then I can use the system as normal. Let's say I type cat /etc/passwd, the output of that program would be similar to /bin/cat /etc/passwd I can't use lsof because I can't get the timing right. Is this clear or do you need more information?

• design function: underlying structure to store list of results for print to file

  - by forest.peterson

  is this a good approach to print a list of items to csv file with a sublist attached to each item. The gist of the function is when an item is found that does not exactly macth then a list of close matches is generated - this works now writing out one list at a time to a command window. For export to a csv file I think all the lists must be generated, stored and then written at once. Right now I use a struct to store the attributes printed, each struct is an item on the list - these structs are then added to a sorted stack and when printed they pop off into write out. Is a stack of stacks of structs a good design?

• Java Swing- Create a function to add elements to JScrollPanel

  - by battousai622

  I want to create a function so that i can call add JLabel's, etc inside the JScrollPanel. I am not sure what the command is in NetBeans. I tried doing JScrollPanel - events - container - componentAdded to create the code below. But nothing shows up when i add code to that function. private void initComponents() { scrollPanel = new javax.swing.JScrollPane(); scrollPanel.addContainerListener(new java.awt.event.ContainerAdapter() { public void componentAdded(java.awt.event.ContainerEvent evt) { scrollPanelComponentAdded(evt); } } private void scrollPanelComponentAdded(java.awt.event.ContainerEvent evt) { System.out.println("main"); } Any help would be great, thanks.

• Perl launched from Java takes forever

  - by Wade Williams

  I know this is an absolute shot in the dark, but we're absolutely perplexed. A perl (5.8.6) script run by Java (1.5) is taking more than an hour to complete. The same script, when run manually from the command line takes 12 minutes to complete. This is on a Linux host. Logging is the same in both cases and the script is run with the same parameters in both cases. The script does some complex stuff like Oracle DB access, some scp's, etc, but again, it does the exact same actions in both cases. We're stumped. Has anyone ever run into a similar situation? If not and if you were faced with the same situation, how would you consider debugging it?

• Coarse classing based on weight of evidence in r

  - by user3619169

  How can we use weight of evidence for binning continuous data in R. For e.g. I have a data: Recency 364 91 692 13 126 4 40 93 13 33 262 12 136 21 88 16 4 19 24 89 36 5 274 125 740 6 13 715 591 443 104 853 260 125 62 357 559 155 163 16 433 91 1380 96 374 130 574 101 5 11 34 401 13 215 168 So, what should be the command to bin this variable in different groups, based on Weight of evidence, or you can say coarse classing. Output I want is: Group I: Recency <200 Group I: Recency 200-400 Group I: Recency 400 Thanks

• wget: retrieving files recursively

  - by Shadow

  When using wget with the recursive option turned on I am getting an error message when it is trying to download a file. It thinks the link is a downloadable file when in reality it should just be following it to get to the page that actually contains the files that I want. wget -r -l 16 --accept=jpg website.com The error message is: .... since it should be rejected. This usually occurs when the website link it is trying to fetch ends with a sql statement. The problem however doesn't occur when using the very same wget command on that link. I want to know how exactly it is trying to fetch the pages. I guess I could always take a poke around the source although I don't know how messy the project is.

• How to execute maven tasks in eclipse (Sonatype plugin)

  - by Bruce

  Hi all I know it must be something simple, but I just can't figure it out.. I'm using the Sonatype maven plugin on eclipse. When I want to build a war file for a webapp project, the only way I know to do it is to use the command line and type mvn package. I've looked all through the right click menu and I can't find any way to do it from eclipse. There's a maven submenu that seems to have no options to do with building, and there's a run menu that doesn't seem right - I don't want to run my project - I just want to build it. There is a maven build option in the run menu, but if I run it, a configuration window pops up for me to enter goals in.. How I do I just do a simple mvn package, but through gui? What am I missing? Thanks!

• how to revert non-corrupted mssql database with stopat

  - by Yisman

  i have a good, working valid non-corrupted database in mssql that i want to revert to a point in time how is that done? the standard RESTORE command requires a full backup as a starting point, and then log backups thereafter. i cant understand why this must be done from a backup. if my db is good and the logs are OK, why cant i just revert with a STOPAT from the live logs in the db? one dba suggested that whenever i want to restore i should THEN make a log backup and then RESTORE with STOPAT. i believe it would work but sounds a little backwards any better ideas? thank you very much

• Java: Executing a Java application in a separate process

  - by _ande_turner_

  Can a Java application be loaded in a separate process using its name, as opposed to its location, in a platform independent manner? I know you can execute a program via ... Process process = Runtime.getRuntime().exec( COMMAND ); ... the main issue of this method is that such calls are then platform specific. Ideally, I'd wrap a method into something as simple as... EXECUTE.application( CLASS_TO_BE_EXECUTED ); ... and pass in the fully qualified name of an application class as CLASS_TO_BE_EXECUTED.

• Exposing console apps to the web with Ruby

  - by Aaron

  I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

• Unable to locate using find element by link

  - by First Rock

  Newbie in testing. I generated a test case using Selenium, and then exported it as a Python script. Now, when I try to run that in terminal, I get following error: raise exception_class(message, screen, stacktrace) NoSuchElementException: Message: u'Unable to locate element: {"method":"link text","selector":"delete"}' I am using the command generated by Selenium i.e driver.find_element_by_link_text("delete").click() The reason for the error I believe is that the link "delete" in my web page is seen only when I click on a particular line to be deleted. So I guess it is being unable to locate the link. Please suggest what alternative measure could I use to locate and click on the "delete" link. Thanks in Advance:)

• Detect response from Modem?

  - by GoodBoyNYC

  I'm working with a Teltonika G10 GSM modem and wrote up a basic program to send out SMS. I put a 1.5 second timer between each AT command to allow the modem to simulate the wait for the "OK" from the modem. This works for now but I'd rather use a branching statement wait for an actual response such as "OK" or "ERROR" rather than using a timer. SerialPort1.Write("AT+CMGD=1,4" & vbCrLf) Thread.Sleep(1250) SerialPort1.Write("AT+CMGF=1" & vbCrLf) Thread.Sleep(1250) SerialPort1.Write("AT+CMGS=" & Chr(34) & "3475558223" & Chr(34) & vbCrLf) Thread.Sleep(1250) SerialPort1.Write(":|" & Chr(26))
