  • Why doesn't Windows XP show "Total Size" and "Free Space" for USB flash disks?

    - by Mehper C. Palavuzlar
    When I double click on My Computer, I can immediately see the Total size and Free space for internal and external HDDs, and inserted CD/DVD media, but in the same columns I cannot see these values for any USB flash drives. They are just empty. To see, I have to right click on USB drive letter, and select Properties. Is there a trick to make Windows XP display USB drive's Total size and Free space in My Computer window?

  • I want to increase the size of my boot partition (Ubuntu 14.04 version) [duplicate]

    - by Mike
    This question already has an answer here: How do I free up more space in /boot? 11 answers How to resize partitions? 5 answers I read in another post that kernels are distributed as new releases rather than upgrades. I didn't know this when I was allocating space to my partitions during my initial install of Ubuntu. As a result I ran out of space on my boot partition. Can I increase the size of it using GParted and how do I do this without doing damage to my system? 1 1049kB 512MB 511MB fat32 boot 2 512MB 768MB 256MB ext2 3 768MB 1000GB 999GB lvm Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/ubuntu--vg-swap_1: 3712MB Sector size (logical/physical): 512B/4096B Partition Table: loop Number Start End Size File system Flags 1 0.00B 3712MB 3712MB linux-swap(v1) Model: Linux device-mapper (linear) (dm) Disk /dev/mapper/ubuntu--vg-root: 996GB Sector size (logical/physical): 512B/4096B Partition Table: loop Number Start End Size File system Flags 1 0.00B 996GB 996GB ext4 Sorry, don't know how to capture and post the terminal output screen.

  • How to insert and call by row and column into sqlite3 python, great tutorial problem.

    - by user291071
    Lets say i have a simple array of x rows and y columns with corresponding values, What is the best method to do 3 things? How to insert, update a value at a specific row column? How to select a value for each row and column, import sqlite3 con = sqlite3.connect('simple.db') c = con.cursor() c.execute('''create table simple (links text)''') con.commit() dic = {'x1':{'y1':1.0,'y2':0.0},'x2':{'y1':0.0,'y2':2.0,'y3':1.5},'x3':{'y2':2.0,'y3':1.5}} ucols = {} ## my current thoughts are collect all row values and all column values from dic and populate table row and columns accordingly how to call by row and column i havn't figured out yet ##populate rows in first column for row in dic: print row c.execute("""insert into simple ('links') values ('%s')"""%row) con.commit() ##unique columns for row in dic: print row for col in dic[row]: print col ucols[col]=dic[row][col] ##populate columns for col in ucols: print col c.execute("alter table simple add column '%s' 'float'" % col) con.commit() #functions needed ##insert values into sql by row x and column y?how to do this e.g. x1 and y2 should put in 0.0 ##I tried as follows didn't work for row in dic: for col in dic[row]: val =dic[row][col] c.execute("""update simple SET '%s' = '%f' WHERE 'links'='%s'"""%(col,val,row)) con.commit() ##update value at a specific row x and column y? ## select a value at a specific row x and column y?

  • SQL SERVER – ColumnStore Index – Batch Mode vs Row Mode

    - by pinaldave
    What do you do when you are in a hurry and hear someone say things which you do not agree or is wrong? Well, let me tell you what I do or what I recently did. I was walking by and heard someone mentioning “Columnstore Index are really great as they are using Batch Mode which makes them seriously fast.” While I was passing by and I heard this statement my first reaction was I thought Columnstore Index can use both – Batch Mode and Row Mode. I stopped by even though I was in a hurry and asked the person if he meant that Columnstore indexes are seriously fast because they use Batch Mode all the time or Batch Mode is one of the reasons for Columnstore Index to be faster. He responded that Columnstore Indexes can run only in Batch Mode. However, I do not like to confront anybody without hearing their complete story. Honestly, I like to do information sharing and avoid confronting as much as possible. There are always ways to communicate the same positively. Well, this is what I did, I quickly pull up my earlier article on Columnstore Index and copied the script to SQL Server Management Studio. I created two versions of the script. 1) Very Large Table 2) Reasonably Small Table. I a query which uses columnstore index on both of the versions. I found very interesting result of the my tests. I saved my tests and sent it to the person who mentioned about that Columnstore Indexes are using Batch Mode only. He immediately acknowledged that indeed he was incorrect in saying that Columnstore Index uses only Batch Mode. What really caught my attention is that he also thanked me for sending him detail email instead of just having argument where he and I both were standing in the corridor and neither have no way to prove any theory. Here is the screenshots of the both the scenarios. 1) Columnstore Index using Batch Mode 2) Columnstore Index using Row Mode Here is the logic behind when Columnstore Index uses Batch Mode and when it uses Row Mode. A batch typically represents about 1000 rows of data. Batch mode processing also uses algorithms that are optimized for the multicore CPUs and increased memory throughput.  Batch mode processing spreads metadata access costs and overhead over all the rows in a batch.  Batch mode processing operates on compressed data when possible leading superior performance. Here is one last point – Columnstore Index can use Batch Mode or Row Mode but Batch Mode processing is only available in Columnstore Index. I hope this statement truly sums up the whole concept.

  • Mouse pointer size inconsistent

    - by charon00
    Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

  • Problem to match font size to the screen resolution in libgdx

    - by Iñaki Bedoya
    I'm having problems to show text on my game at same size on different screens, and I did a simple test. This test consists to show a text fitting at the screen, I want the text has the same size independently from the screen and from DPI. I've found this and this answer that I think should solve my problem but don't. In desktop the size is ok, but in my phone is too big. This is the result on my Nexus 4: (768x1280, 2.0 density) And this is the result on my MacBook: (480x800, 0.6875 density) I'm using the Open Sans Condensed (link to google fonts) As you can see on desktop looks good, but on the phone is so big. Here the code of my test: public class TextTest extends ApplicationAdapter { private static final String TAG = TextTest.class.getName(); private static final String TEXT = "Tap the screen to start"; private OrthographicCamera camera; private Viewport viewport; private SpriteBatch batch; private BitmapFont font; @Override public void create () { Gdx.app.log(TAG, "Screen size: "+Gdx.graphics.getWidth()+"x"+Gdx.graphics.getHeight()); Gdx.app.log(TAG, "Density: "+Gdx.graphics.getDensity()); camera = new OrthographicCamera(); viewport = new ExtendViewport(Gdx.graphics.getWidth(), Gdx.graphics.getWidth(), camera); batch = new SpriteBatch(); FreeTypeFontGenerator generator = new FreeTypeFontGenerator(Gdx.files.internal("fonts/OpenSans-CondLight.ttf")); font = createFont(generator, 64); generator.dispose(); } private BitmapFont createFont(FreeTypeFontGenerator generator, float dp) { FreeTypeFontGenerator.FreeTypeFontParameter parameter = new FreeTypeFontGenerator.FreeTypeFontParameter(); int fontSize = (int)(dp * Gdx.graphics.getDensity()); parameter.size = fontSize; Gdx.app.log(TAG, "Font size: "+fontSize+"px"); return generator.generateFont(parameter); } @Override public void render () { Gdx.gl.glClearColor(1, 1, 1, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); int w = -(int)(font.getBounds(TEXT).width / 2); batch.setProjectionMatrix(camera.combined); batch.begin(); font.setColor(Color.BLACK); font.draw(batch, TEXT, w, 0); batch.end(); } @Override public void resize(int width, int height) { viewport.update(width, height); } @Override public void dispose() { font.dispose(); batch.dispose(); } } I'm trying to find a neat way to fix this. What I'm doing wrong? is the camera? the viewport? UPDATE: What I want is to keep the same margins in proportion, independently of the screen size or resolution. This image illustrates what I mean.

  • Wireshark TCP Window Size Value

    - by T Vernon
    I am debugging an application with Wireshark and watching the TCP Window Size value shrink on one side of the communication. If the packet's TCP section shows a "Window size value: 1", does that mean the source's window size is 1 or the destination's window size is 1? I know one side is communicating faster than the other can handle, I just want be sure I know which one it is. 1 192.168.0.1 - 192.168.0.100, Modbus/TCP, Length: 66, Window Size Value: 1 2 192.168.0.100 - 192.168.0.1, TCP, Length: 60, Window Size Value: 92 3 192.168.0.100 - 192.168.0.1 TCP, Length: 310, Window Size Value: 92 4 192.168.0.1 - 192.168.0.100 TCP, Length: 54, Window Size Value: 0 So is 192.168.0.1's window size 0 or is it reporting that 192.168.0.100's window is 0? Thanks.

  • Problem with deleting table rows using ctrl+a for row selection

    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} The following code is commonly shown and documented for how to access the row key of selected table rows in an ADF Faces table configured for multi row selection. public void onRemoveSelectedTableRows(ActionEvent actionEvent) {    RichTable richTable = … get access to your table instance …    CollectionModel cm =(CollectionModel)richTable.getValue();    RowKeySet rowKeySet = (RowKeySet)richTable.getSelectedRowKeys();             for (Object key : rowKeySet) {       richTable.setRowKey(key);       JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();       // do something with rowData e.g.update, print, copy   }    //optional, if you changed data, refresh the table         AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance(); adfFacesContext.addPartialTarget(richTable);   return null; } The code shown above works for 99.5 % of all use cases that deal with multi row selection enabled ADF Faces tables, except for when users use the ctrl+a key to mark all rows for delete. Just to make sure I am clear: if you use ctrl+a to mark rows to perform any other operation on them – like bulk updating all rows for a specific attribute – then this works with the code shown above. Even for bulk row delete, any other mean of row selection (shift+click and multiple ctrl+click) works like a charm and the rows are deleted. So apparently it is the use of ctrl+a that causes the problem when deleting multiple rows of an ADF Faces table. To implement code that works for all table selection use cases, including the one to delete all table rows in one go, you use the code shown below. public void onRemoveSelectedTableRows(ActionEvent actionEvent) {   RichTable richTable = … get access to your table instance …   CollectionModel cm = (CollectionModel)richTable.getValue();   RowKeySet rowKeySet = (RowKeySet)richTable.getSelectedRowKeys();   Object[] rowKeySetArray = rowKeySet.toArray();      for (Object key : rowKeySetArray){               richTable.setRowKey(key);     JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();                              rowData.getRow().remove();   }   AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();          adfFacesContext.addPartialTarget(richTable); }

    What I am trying to do is: (programmatically) Update status where id is something, if no rows where updated, give error: we cannot find the record with id something, otherwise give message success. Here I am using mysql_affected_rows() to know if a row was updated or not, but it always return 1, so the user gets a success message, even though there was no row updated. Can anyone tell me what could it be?

  • How can I change the amount and size of Linux ramdisks (/dev/ram0 - /dev/ram15)?

    - by Kevin S.
    Using Linux, when I boot I automatically have 16 16MB ramdisks, however, I would like to create one really large ramdisk to test some software. I found that I can adjust the size of the ramdisks already on the system with the kernel boot parameter ramdisk_size however, this makes all 16 ramdisks (/dev/ram0 - /dev/ram15) the size that is specified. So if I want to create a 1GB ramdisk, I would need 16GB of memory. Basically, I want to create one 10GB ramdisk which would be /dev/ram0. How would I go about doing that? I assume there is a kernel boot parameter, but I just haven't found it.

  • Can we solve the table row background image problem, in chrome, in multi celled tables??

    - by Ya'el
    It is frequently asked – but I haven’t seen a good answer yet (and I looked). If you set a background image in CSS to a table row- the image will repeat itself in every cell. If you set the position: relative (for the row) and set the background-image: none (for the cells) it solves the problem on IE but not on chrome! I can't use background positioning since there are many calls and their size varies. (And the picture is not symmetrical- It's a fade out from one side. Anybody?? Example for the css code : tr { height: 30px; position:relative;} tr.green {background: url('green_30.png') no-repeat left top;} tr.orange {background: url('oranger_30.png') no-repeat left top;} tr.red {background: url('red_30.png') no-repeat left top;} td {background-image:none;} The HTML is basic - A multi cell table. The goal is to have different colors fade into every row, but it could be any non-pattern image.

  • Sql Server 2005 Database Tables - Row Comparison Column By Column.

    - by Goober
    Scenario I have an TWO datbase tables of exactly the SAME STRUCTURE. The difference between these tables is that one contains data populated by one application and the other is populated by a different application. Each application is trying to produce the same result, but using two different methods of implementation. Proposed Idea What I want to do, is run both applications, which will roughly produce 35000 rows containing 10 columns each - So all in all, 70000 rows of data, I then want to compare each row of data, COLUMN BY COLUMN to check whether the values are the same or not. Current Thoughts Since there is so much data to compare, I feel that the best way in which to do this would be to write an application, preferably in C# (but if necessary, T-sql), to compare each row of data column by column, and write out any failed comparisons to a text log file. Question Could anybody suggest an efficient way in which to perform column by column row comparison for 70000 rows worth of data? I'm struggling for ideas on how to tackle this problem. Extra Detail The two applications are both written in C# .Net 3.5. The Database is running on Sql Server 2005. Help greatly appreciated.

  • To what extent is size a factor in SSD performance?

    - by artif
    To what extent is the size of an SSD a factor in its performance? In my mind, correct me if I'm wrong, a bigger SSD should be, everything else being equal, faster than a smaller one. A bigger SSD would have more erase blocks and thus more leeway for the FTL (flash translation layer) to do garbage collection optimization. Also there would be more time before TRIM became necessary. I see on Wikipedia that it remarks that "The performance of the SSD can scale with the number of parallel NAND flash chips used in the device" so it seems throughput also increases significantly. Also many SSDs contain internal caches of some sort and presumably those caches are larger for correspondingly large SSDs. But supposing this effect exists, I would like a quantitative analysis. Does throughput increase linearly? How much is garbage collection impacted, if at all? Does latency stay the same? And so on. Would the performance of a 8 GB SSD be significantly different from, for example, an 80 GB SSD assuming both used high quality chips, controllers, etc? Are there any resources (webpages, research papers, presentations, books, etc) that discuss correlations between SSD performance (4 KB random write speed, latency, maximum sequential throughput, etc) and size? I realize this does not really sound like a programming question but it is relevant for what I'm working on (using flash for caching hard drive data) which does involve programming. If there is a better place to ask this question, eg a more hardware oriented site, what would that be? Something like the equivalent of stack overflow (or perhaps a forum) for in-depth questions on hardware interfaces, internals, etc would be appreciated.

  • SQL SERVER – Size of Index Table for Each Index – Solution 2

    Earlier I had ran puzzle where I asked question regarding size of index table for each index in database over here SQL SERVER – Size of Index Table – A Puzzle to Find Index Size for Each Index on Table. I had received good amount answers and I had blogged about that here SQL SERVER – Size of Index Table for Each Index – Solution. As a comment to that blog I have received another very interesting comment and that provides near accurate answers to original question. Many thanks to Rama Mathanmohan for providing wonderful solution. SELECT OBJECT_NAME(i.OBJECT_ID) AS TableName, i.name AS IndexName, i.index_id AS IndexID, 8 * SUM(a.used_pages) AS 'Indexsize(KB)' FROM sys.indexes AS i JOIN sys.partitions AS p ON p.OBJECT_ID = i.OBJECT_ID AND p.index_id = i.index_id JOIN sys.allocation_units AS a ON a.container_id = p.partition_id GROUP BY i.OBJECT_ID,i.index_id,i.name ORDER BY OBJECT_NAME(i.OBJECT_ID),i.index_id Let me know if you have any better script for the same.

  • Changing how a telerik radgrid marks a row as "modified"

    - by Scott Vercuski
    I am working with the Telerik Winforms Radgrid version 2009.2.9.701 in visual studio 2008 (C#) and I've come across and issue I can't seem to find a solution for. When the radgrid is populated and the user changes a cell within a row, the row is not flagged as "modified" until the user actually clicks onto another location on the datagrid. If the user modifies any values in a row and immediately clicks the "Save" button on my winform, the row is not flagged as having been modified and is not showing up in my list of modified rows. I am using the following code to gather the modified rows ... DataTable modifiedRows = dataTable.GetChanges(DataRowState.Modified); My question is as follows: Is there a way to mark a row as "Modified" when the user changes a value in ANY cell in the row, without the user having to click off of the row before clicking the save button. I can't seem to find the flag that marks a data row as "Modified". Thank you for your help, it is much appreciated.

  • Increase the size of Taskbar Preview Thumbnails in Windows 7

    - by Matthew Guay
    Taskbar thumbnail previews are incredibly useful in Windows 7, but for some users they may be too small.  Here’s a tool to help you make your taskbar thumbnail previews just like you want them. A few years ago we featured a tool to increase the size of your thumbnail previews in Windows Vista, but unfortunately this application doesn’t work correctly in Windows 7.  However, there is a new tool for Windows 7 that lets you customize your taskbar thumbnail previews even more in Windows 7.  With it, you can change almost anything about your taskbar thumbnail previews.  The default taskbar thumbnails are nice, but may be too small for users with vision problems or with very high resolution monitors.  Whatever your need, this is a great tool to make the thumbnails looks and work just like you want. Let’s get started Download the Windows 7 Taskbar Thumbnail Customizer (link below), and unzip the files.  Run the Windows 7 Taskbar Thumbnail Customizer when you’re done.  Simply double-click on it; you don’t need to run it as administrator. Now, you change the size, spacing, margin, and delay time of your taskbar thumbnails.  The Delay Time setting is very handy; to speed things up, we set it to 0 so there’s no delay between when you mouse-over a taskbar icon to when you see the thumbnail.  Simply drag the slider to the size (or time in the delay settings) you want, and click Apply settings.  Windows Explorer will automatically restart, and your new taskbar thumbnails will be ready to use. Here is the default Windows 7 thumbnail preview of a video playing in Media player: And here’s the taskbar thumbnail enlarged to 380px.  Now you can really watch a video from your taskbar thumbnail. The larger taskbar thumbnails show up a little different in Internet Explorer.  It shows a larger preview of your active tab, and smaller previews of your other tabs.  Notice also that Aero peek shows the tab you’re hovering over in Internet Explorer, but the tab name in IE’s toolbar doesn’t change to the one you’re previewing.   Here we increased the width between the thumbnails, while keeping the thumbnails at their default size.  This could be useful if you have trouble selecting the correct preview, and we can imagine it would be a very useful modification on touch screens. And, if you ever take your changes too far, and want to revert to your default Windows 7 taskbar thumbnail previews, simply run the Customizer again and select Restore Defaults.  Windows Explorer will restart again, and your taskbar thumbnails will be back to their default settings.   Conclusion This tool makes it safe and easy to change the size, spacing, and more of your taskbar thumbnail previews.  And since you can always revert to the default settings, you can experiment without fear of messing up your computer.  If you’d prefer to change the settings manually without using a dedicated application, here’s a list of the registry changes you can make to accomplish this by hand.

  • DataGridView display row header cell

    - by Karl
    I'm trying to display a simple DataGridView linked to a DataTable and I want, ultimately, my first column in the DataTable to be the row header cell for the DataGridView. At this point I will settle for having any value in the row header cell. I can display the DataGridView with all my rows and columns, and with column header cells, but no row header cell. I check the value in the row.HeaderCell.Value, and the data I put there is there. I check row.HeaderCell.Displayed and it is false, but this is read only, so I can't make it true. How do I make the row header cell display? Here's a simple sample of what I've tried to get this to work: DataTable table = new DataTable(); for (int i = 0; i<10; i++) { table.Columns.Add(new DataColumn("column-" + i)); } for (int i = 0; i < 10; i++) { DataRow theRow = table.NewRow(); for (int j = 0; j < 10; j++) theRow[j] = i + "-" + j; table.Rows.Add(theRow); } dataGridView1.DataSource = table; dataGridView1.RowHeadersWidthSizeMode = System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders; int rowNumber = 1; foreach (DataGridViewRow row in dataGridView1.Rows) { if (row.IsNewRow) continue; row.HeaderCell.Value = "Row " + rowNumber; rowNumber = rowNumber + 1; } dataGridView1.AutoResizeRowHeadersWidth( DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);

  • Repeat row headers after Page Break

    - by klaus.fabian
    The lead developer of the FO engine send me by chance an email about a REALLY nice feature I did not know about. Did you ever encounter a long table with merged cells, where the merged cell went on to the next page? While column headers are by default repeated on the next page, row headers are not. Tables with group-left column and pivot tables are prime examples where this problem occurs. I have seen reports where merged cells could go over multiple pages and you would need to back to find the row header on previous pages. The BI Publisher RTF templates have a special tag you can added to a merged cell to repeat the contents after each page break. You just need to add the following (wordy) tag to the next merged table cell: true Example: 2nd page of report before adding the tag 2nd page of report after adding the tag. Thought you might want to know. Klaus

  • Bad FPS for smaller size (OpenGL ES with SDL)

    - by ber4444
    If you saw my other question, well, there is still a little problem: Click here to watch on youtube Basically, the frame rate is very bad on the actual device, where for some reason the animation is scaled (it looks like the left side on the video). It is quite fast on the simulator where it is not scaled (right side). For a test, I submitted this new changeset that hard-codes the smaller size (plus increases the point size for HII regions to make the dust clouds more visible), and as you see in the video, now it is slow even in the simulator (left side shows the small size, right side shows the original size -- otherwise the code is the same). I'm clueless why it's soooo slow with a smaller galaxy, in fact it should be FASTER. As for general speed optimization (which is not strictly part of my question but is closely related to it, esp. if we need a workaround to speed things up), some initial ideas: reducing the number of items drawn may affect the appearance negatively but screen resolution could be reduced there are too many glBegin(GL_POINTS)/glEnd() blocks, we could draw more than just a single star at once
