  • Getting memory usage from 'ps aux' output with awk

    - by JustB
    Hello everybody, I have to solve an exercise using awk. Basically I need to retrieve from 'ps aux' command the total of memory usage for each user and format like this: User Total%Mem user1 3.4% user2 1.5% and so on. The problem I can't seem to solve is: how do I know how many users are logged in? And how can I make a different sum for each one of them? Thank you :)

  • MySQL - getting SUM of MAX results from 2 tables

    - by SODA
    Hi, Here's my problem: I have 2 identical tables (past month data, current month data) - data_2010_03, data_2010_04: Content_type (VARCHAR), content_id (INT), month_count (INT), pubDate (DATETIME) Data in month_count is updated hourly, so for each combination of content_type and content_id we insert new row, where value of month_count is incrementally updated. Now I try something like this: SELECT MAX(t1.month_count) AS max_1, MAX(t2.month_count) AS max_2, SUM(max_1 + max_2) AS result, t1.content_type, t1.content_id FROM data_2010_03 AS t1 JOIN data_2010_04 AS t2 ON t1.content_type = t2.content_type AND t1.content_id = t2.content_id WHERE t2.pubDate < '2010-04-08' AND t1.content_type = 'video' GROUP BY t1.content_id ORDER BY result desc, max_1 desc, max_2 desc LIMIT 0,10 I get an error "Unknown column 'max_1' in 'field list'. Please help.

  • How to tell Subversion to display binary files using an external program?

    - by lamcro
    I have some code which, like java, is stored in a binary format, and I have the applications to display and modify this code setup in the Subversion's config file. But when I run svn diff for these file, Subversion prevents me =================================================================== Cannot display: file marked as a binary type. svn:mime-type = application/octet-stream I can still view them, but only with the --force argument Since all the files in the repository are of this binary code, how can I permanently force subversion to open the files for diff or edit mode?

  • simile exhibit ie7 bug

    - by two7s_clash
    'm using to Exhibit to, pretty simply, display some data on historical events and book publication dates: http://f1shw1ck.com/timeline3/exhibit.html Everything works fine, and I have been able to get the timeline running as wanted, until I try to take control of the timeline with a timelineConfig script. After I add this, my timeline continues to work as expected on all browsers, except for IE. Curiously enough, band 0 initializes and is rendered correctly, but band 1 shows no events and does not sync to the band above. But it is picking up the width: 10%", intervalUnit: Timeline.DateTime.DECADE, intervalPixels: 60 specifications, as they are rendered correctly. Since everything works until I call ex:configuration="timelineConfig", since everything works in the other browsers, and since everything almost works in IE, up to the event painting, I have to imagine this is a javascript coding error on my part, but I just can't see it. All I get in my console is Failed to create view View As Timeline." Incidentally, having or not having the gotoYear function seemingly does nothing to change... Thanks for any tips.

  • Assigning a vector of one type to a vector of another type

    - by deworde
    Hi, I have an "Event" class. Due to the way dates are handled, we need to wrap this class in a "UIEvent" class, which holds the Event, and the date of the Event in another format. What is the best way of allowing conversion from Event to UIEvent and back? I thought overloading the assignment or copy constructor of UIEvent to accept Events (and vice versa)might be best.

  • Is it possible to define a generic lambda?

    - by Mike OBrien
    I have some logic in a method that operates on a specified type and I'd like to create a generic lambda that encapsulates the logic. This is the spirit of what I'm trying to do: public void DoSomething() { // ... Func<T> GetTypeName = () => T.GetType().Name; GetTypeName<string>(); GetTypeName<DateTime>(); GetTypeName<int>(); // ... } I know I can pass the type as a parameter or create a generic method but I'm interested if it can just be a generic lambda (So I'm not looking for alternatives). From what I can tell C# 3.0 doesn't support this. TIA, m

  • How to control order of assignment for new identity column in SQL Server?

    - by alpav
    I have a table with CreateDate datetime field default(getdate()) that does not have any identity column. I would like to add identity(1,1) field that would reflect same order of existing records as CreateDate field (order by would give same results). How can I do that ? I guess if I create clustered key on CreateDate field and then add identity column it will work (not sure if it's guaranteed), is there a good/better way ? I am interested in SQL Server 2005, but I guess the answer will be the same for SQL Server 2008, SQL Server 2000.

  • How do I 'donut cache' in ASP.NET MVC for something more than a date

    - by Simon_Weaver
    All the examples for donut caching I've seen are just like this : <%= Html.Substitute( c => DateTime.Now.ToString() )%> Thats fine if I just want the date, but what other options are there? I know there is a delegate 'MvcSubstitutionCallback' which has the following signature : public delegate string MvcSubstitutionCallback(HttpContextBase httpContext); but RenderAction and RenderPartial returns void so i cant just return them from the delegate method. How can I effectively use this callback for more complex situations. I've looked at both of Phil Haacked's articles here and here, but neither seems to do exactly what I want.

  • Expression Too Complex In Access 2007

    - by Jazzepi
    When I try to run this query in Access through the ODBC interface into a MySQL database I get an "Expression too complex in query expression" error. The essential thing I'm trying to do is translate abbreviated names of languages into their full body English counterparts. I was curious if there was some way to "trick" access into thinking the expression is smaller with sub queries, or if someone else had a better idea of how to solve this problem. I thought about making a temporary table and doing a join on it, but that's not supported in Access SQL. Just as an FYI, the query worked fine until I added the big long IFF chain. I tested the query on a smaller IFF chain for three languages, and that wasn't an issue, so the problem definitely stems from the huge IFF chain (It's 26 deep). Also, I might be able to drop some of the options (like combining the different forms of Chinese or Portuguese) As a test, I was able to get the SQL query to work after paring it down to 14 IFF() statements, but that's a far cry from the 26 languages I'd like to represent. SELECT TOP 5 Count( * ) AS [Number of visits by language], IIf(login.lang="ar","Arabic",IIf(login.lang="bg","Bulgarian",IIf(login.lang="zh_CN","Chinese (Simplified Han)",IIf(login.lang="zh_TW","Chinese (Traditional Han)",IIf(login.lang="cs","Czech",IIf(login.lang="da","Danish",IIf(login.lang="de","German",IIf(login.lang="en_US","United States English",IIf(login.lang="en_GB","British English",IIf(login.lang="es","Spanish",IIf(login.lang="fr","French",IIf(login.lang="el","Greek",IIf(login.lang="it","Italian",IIf(login.lang="ko","Korean",IIf(login.lang="hu","Hungarian",IIf(login.lang="nl","Dutch",IIf(login.lang="pl","Polish",IIf(login.lang="pt_PT","European Portuguese",IIf(login.lang="pt_BR","Brazilian Portuguese",IIf(login.lang="ru","Russian",IIf(login.lang="sk","Slovak",IIf(login.lang="sl","Slovenian","IIf(login.lang="fi","Finnish",IIf(login.lang="sv","Swedish",IIf(login.lang="tr","Turkish","Unknown")))))))))))))))))))))))))) AS [Language] FROM login, reservations, reservation_users, schedules WHERE (reservations.start_date Between DATEDIFF('s','1970-01-01 00:00:00',[Starting Date in the Following Format YYYY/MM/DD]) And DATEDIFF('s','1970-01-01 00:00:00',[Ending Date in the Following Format YYYY/MM/DD])) And reservations.is_blackout=0 And reservation_users.memberid=login.memberid And reservation_users.resid=reservations.resid And reservation_users.invited=0 And reservations.scheduleid=schedules.scheduleid And scheduletitle=[Schedule Title] GROUP BY login.lang ORDER BY Count( * ) DESC; @ Michael Todd I completely agree. The list of languages should have been a table in the database and the login.lang should have been a FK into that table. Unfortunately this isn't how the database was written, and it's not really mine to modify. The languages are placed into the login.lang field by the PHP running on top of the database.

  • Google Chrome extension: Use Javascript inside webkit notifications?

    - by Arnaud Leymet
    I have been following the Google Chrome Extensions Developer's guide and have been able so far to create an extension with a browser action without popup that would trigger a webkit notification in HTML format. Fact is that this HTML file contains action buttons, links and javascript, but none of them seems to respond. Is this a by-design behavior or is there a way for embedding javascript/links/buttons in these webkit notifications?

  • How can I make these images download on a separate thread?

    - by Andy Barlow
    I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really appreciated. private class CatalogAdapter extends ArrayAdapter<SingleQueueResult> { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter. It should send back our new custom rows for the list */ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.mylists_rows, null); } final SingleQueueResult result = items.get(position); // Sets the text inside the rows as they are scrolled by! if (result != null) { TextView title = (TextView)v.findViewById(R.id.mylist_title); TextView format = (TextView)v.findViewById(R.id.mylist_format); title.setText(result.getTitle()); format.setText(result.getThumbnail()); // Download Images ImageView myImageView = (ImageView)v.findViewById(R.id.mylist_thumbnail); downloadImage(result.getThumbnail(), myImageView); } return v; } } // This should run in a seperate thread public void downloadImage(String imageUrl, ImageView myImageView) { try { url = new URL(imageUrl); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is.close(); myImageView.setImageBitmap(bm); } catch (IOException e) { /* Reset to Default image on any error. */ //this.myImageView.setImageDrawable(getResources().getDrawable(R.drawable.default)); } }

  • Disable automatic Date parsing in HtmlUnit

    - by submonoid
    Having just upgraded to a newer version of HtmlUnit (2.4), I've noticed certain tests are failing when comparing the output of asText. Looking into the differences, this is because dates (present on the page in the format 11/06/2010 00:00z) are being altered in the output to read 2010-06-11. Has anybody else encountered this, and can anybody advise how to turn off this (seemingly undocumented) feature of asText, which seems to go completely against the advised documentation.
