  • Can someone recommend a Compact Flash card to be used as a boot disk

    - by Hamish Downer
    I have an early Acer Aspire One netbook, and the flash drive is really slow at writing. I've taken it apart to add more RAM, but I've pretty much stopped using it. I've read about people replacing the SSD with a Compact Flash card and a CF to ZIF adapter but I've also read about some Compact Flash cards where the manufacturer has permanently disabled the boot flag to stop people doing this kind of mod. (Can't find the link any more though). So my most specific question is: can someone recommend a compact flash card that does allow the boot flag to be set? Please say whether you've done it yourself, or just heard about it from someone else. Beyond that, is this generally a problem?

  • In gmail can we make is:unread the default view?

    - by JK-
    In gmail can we make is:unread the default view? That is, when we load gmail can we configure it so that is:unread is already selected, thereby showing only unread messages by default? Or can we at least configure gmail so that it has a 1 click link that only shows unread mail? The reason for this of course is that it is slow and inefficient to have to type is:unread into the gmail search every time I open it. It would be much more convenient for gmail to load this view by itself when I open gmail.

  • Separating user resources - Windows Server 2008 (Terminal Server)

    - by Christopher Wilson
    At the moment I am running a Windows Terminal Server 2008 for around 10 clients that use the server to run programs and access data. Is there anyway to separate the resources of each user so that they do not impact each other in terms of resources. User 1: Opens program User 2: Notices slow down I have looked into using Windows System Resource Manager but do not know if it provides what I need and if there are any other 3rd party tools that also provide this functionality. Any answer is appreciated. Server Specs: HP ProLiant ML110 G7 Processor: Intel® Xeon® E3-1220 (4 core, 3.1 GHz, 8MB, 80W, 1333/t) RAM: 12GB DDR3 ECC 1TB HDD

  • Making a Live Thumb drive boot with Persistent files, settings AND *drivers* that load on boot?

    - by Luke Stanley
    I have seen https://wiki.ubuntu.com/LiveUsbPendrivePersistent but it's a mess. What methods support persistent drivers as well as files and settings and don't screw up lifespan of the flash drive? I'd like to see your personal recommendations on say, Portable Linux, USB Creator, Remastersys + Unetbootin, etc Backstory: I have a Inspiron 1525 that's hard drive has been slowly dying. I want to switch to a live USB/CD/DVD system until I can get it repaired but my laptops internal wifi device requires a network connection by another means for Xubuntu to let it work, and then I have to enter my Wifi key again, and THEN I have to reinstall Skype etc... I'd be damned every time I have to shut the laptop down. I'm ok with making a shell script for installing apps and copying settings as required but a good persistent install should make this old hat and slow and it doesn't take care of drivers. The last time I tried making an ISO with Remastersys it didn't seem to copy all the required settings.

  • Blocking internet poker applications

    - by Matthew Savage
    I 'look after' the wireless internet for a cafe where I live, and we've noticed that there's quite a substantial slow down of internet speeds when certain users are playing internet poker. I've put in filters to block any HTTP traffic referencing gambling and poker etc, however I want to be able to block any applications (i.e. poker clients) which don't use HTTP. I've tried searching around for a list of poker clients and perhaps their ports, but have had no real luck. Does anyone know what these might be?

  • site timing out when under heavy load

    - by naunu
    My client sends out eblasts at 8am monday/wed/friday. Between 8:15-8:45 the site becomes extremely slow and many users sessions timeout. My setup: Mediatemple VE 2gb dedicated ram (3 burst) Ubuntu 9.10 Apache2-mpm-worker PHP5.3-fcgi MySQL 5 I recently tried to remedy the problem by switching from apache2-mpm-prefork to mpm-worker, but am still having the same issues. My apache settings are: Timeout 100 KeepAlive On MaxKeepAliveRequests 100 <IfModule mpm_worker_module> StartServers 12 MinSpareThreads 25 MaxSpareThreads 96 ThreadLimit 96 ThreadsPerChild 25 MaxClients 225 MaxRequestsPerChild 0 </IfModule> The site is only getting ~10,000 page views during the 8am-9am hour, which I dont think should be stressing the server too badly. Maybe it is an error with the PHP settings, or bandwidth per unit time, or the site outgrew the server? Any suggestions would be very helpful - as you can see i've given it a good go before looking for help (installed mpm-worker). Also, can anyone suggest to me some free load testing software, or a tutorial on mod_status? Thank you

  • Python API for VirtualBox

    I have made a command-line interface for virtualbox such that the virtualbox can be controlled from a remote machine. now I am trying to implement the commmand-line interface using python virtualbox api. For that I have downloaded the pyvb package (python api documentation shows functions that can be used for implementing this under pyvb package). but when I give pyvb.vb.VB.startVM(instance of VB class,pyvb.vm.vbVM) SERVER SIDE CODE IS from pyvb.constants import * from pyvb.vm import * from pyvb.vb import * import xpcom import pyvb import os import socket import threading class ClientThread ( threading.Thread ): # Override Thread's init method to accept the parameters needed: def init ( self, channel, details ): self.channel = channel self.details = details threading.Thread.__init__ ( self ) def run ( self ): print 'Received connection:', self.details [ 0 ] while 1: s= self.channel.recv ( 1024 ) if(s!='end'): if(s=='start'): v=VB() pyvb.vb.VB.startVM(v,pyvb.vm.vbVM) else: self.channel.close() break print 'Closed connection:', self.details [ 0 ] server = socket.socket ( socket.AF_INET, socket.SOCK_STREAM ) server.bind ( ( '127.0.0.1', 2897 ) ) server.listen ( 5 ) while True: channel, details = server.accept() ClientThread ( channel, details ).start() it shows an error Exception in thread Thread-1: Traceback (most recent call last): File "/usr/lib/python2.5/threading.py", line 486, in __bootstrap_inner self.run() File "news.py", line 27, in run pyvb.vb.VB.startVM(v,pyvb.vm.vbVM.getUUID(m)) File "/usr/lib/python2.5/site-packages/pyvb-0.0.2-py2.5.egg/pyvb/vb.py", line 65, in startVM cmd='%s %s'%(VB_COMMAND_STARTVM, vm.getUUID()) AttributeError: 'str' object has no attribute 'getUUID'

  • Throttle connections to web service if load gets too high?

    - by Joseph Turian
    I have a web site that communicates via XMLRPC with an XMLRPC server web service. (The web service is written in Python using xmlrpclib.) I believe that xmlrpclib will block while it is handling one request. So if there are three users with an xmlrpclib request ahead of you, your response takes four times as long. How do I handle it if I receive too many XMLRPC requests and the web service gets bogged down and has slow response time? If I am getting slashdotted, my preferred behavior is that the first users get good response times and everyone else is told to come back later. I think this is superior to giving everyone terrible response times. How do I create this behavior? Is this called load-balancing? I am not actually balancing though, until I have multiple servers.

  • Can I indicate where my MySQL parameter should go more meaningfully than just having a ? to mark the

    - by Paul H
    I've got a chunk of code where I can pass info into a MySQL command using parameters through an ODBC connection. Example code showing surname passed in using string surnameToLookFor: using (OdbcConnection DbConn = new OdbcConnection( connectToDB )) { OdbcDataAdapter cmd = new OdbcDataAdapter( "SELECT Firstname, Address, Postcode FROM customers WHERE Surname = ?", DbConn); OdbcParameter odbcParam = new OdbcParameter("surname", surnameToLookFor); cmd.SelectCommand.Parameters.Add(odbcParam); cmd.Fill(dsCustomers, "customers"); } What I'd like to know is whether I can indicate where my parameter should go more meaningfully than just having a ? to mark the position - as I could see this getting quite hard to debug if there are multiple parameters being replaced. I'd like to provide a name to the parameter in a manner something like this: SELECT Firstname, Address, Postcode FROM customers WHERE Surname = ?surname ", When I try this it just chokes. The following code public System.Data.DataSet Customer_Open(string sConnString, long ld) { using (MySqlConnection oConn = new MySqlConnection(sConnString)) { oConn.Open(); MySqlCommand oCommand = oConn.CreateCommand(); oCommand.CommandText = "select * from cust_customer where id=?id"; MySqlParameter oParam = oCommand.Parameters.Add("?id", MySqlDbType.Int32); oParam.Value = ld; oCommand.Connection = oConn; DataSet oDataSet = new DataSet(); MySqlDataAdapter oAdapter = new MySqlDataAdapter(); oAdapter.SelectCommand = oCommand; oAdapter.Fill(oDataSet); oConn.Close(); return oDataSet; } } is from http://www.programmingado.net/a-389/MySQL-NET-parameters-in-query.aspx and includes the fragment where id=?id Which would be ideal. Is this only available through the .Net connector rather than the ODBC? If it is possible to do using ODBC how would I need to change my code fragment to enable this?

  • Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

    - by jonathanconway
    I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

  • How backward compatible are the HSDPA mobile networks

    - by Chris Kimpton
    Hi, I have got this Huawei wifi device, which has been unlocked for other networks. Works fine in UK on Vodafone (as well as 3). We are trying to get it to work with the Claro network in Jamaica. It connects and stays connected, but fails to get a 3g connection, just the slow EDGE one. Claro support say its because Claro currently does not support the 2100MHz frequency for 3G, which is what the device uses Does that sound correct? They say I need one that: Ensure however that these devices can use the 850MHz frequency. My understanding was that the device supports up to 2100, including their 850mhz... I am thinking that maybe the APN is incorrect, but I have set it to the only value I can find on the net, namely: internet.ideasclaro.com.jm Thanks in advance, Chris

  • Driverpack Solution makes a whole bunch of programs

    - by Markasoftware
    I am using Driver Pack solution 12.3 to update my drivers. I used it and installed 55 drivers. I noticed that there are now several dozen new entries in add/remove programs under the name Windows Driver Package - Intel hdc, Windows Driver Package - Intel System, and Windows Driver Package - Intel USB with the driverpack solution logo next to them. When I hit uninstall for any of these, it says all devices using this driver will be removed, and I am scared of uninstalling anything I do not know about. I have no system restore points before I updated my driver. Will these extra driver packages slow down my computer or take up extra disk space? Can I uninstall them safely? I am using Windows 8, so refreshing the computer is an option.

  • Doctrine does not export relation properly

    Hi, I've got a MySQL 5.1.41 database which i'm trying to fill with doctrine, but doctrine does not insert the relations correctly.

If i manually set the foreign key to ON_UPDATE CASCADE it does work. Why does doctrine not set this option? I got it to work in Propel, but i really want to use doctrine for this.

  • Why does storage's performance change at various queue depths?

    - by Mxx
    I'm in the market for a storage upgrade for our servers. I'm looking at benchmarks of various PCIe SSD devices and in comparisons I see that IOPS change at various queue depths. How can that be and why is that happening? The way I understand things is: I have a device with maximum (theoretical) of 100k IOPS. If my workload consistently produces 100,001 IOPS, I'll have a queue depth of 1, am I correct? However, from what I see in benchmarks some devices run slower at lower queue depths, then speedup at depth of 4-64 and then slow down again at even larger depths. Isn't queue depths a property of OS(or perhaps storage controller), so why would that affect IOPS?

  • secure synchronization of large amount of data

    - by goncalopp
    I need to automatically mirror a large amount (terabytes) of files in two unix machines over a slow link (1 Mbps). This needs to be done frequently, but the data doesn't change too much (delta transmission doesn't saturate the link). The usual solution would be rsync, but there's an additional requirement: it's undesirable, from a security standpoint, that either the source or destination machines have (keyless) ssh keys to each other, or any kind of filesystem access. All communication between the two machines should thus be initialized (and mediated) through a third machine. I've asked a separate question about rsync in particular here. Are there other obvious solutions I'm missing?

  • Advantage of using nexenta vs. OpenSolaris

    - by jotango
    I am currently building a NAS for about 24 TB of storage. Video files, slow access, long term storage. No performance issues. I am currently undecided between buying a JBOD case and installing OpenSolaris (because of ZFS), or purchasing a Nexenta license. The difference is about $ 12.500 for licenses over three years. What would you see as the main advantage in purchasing a nexenta license, beside the support? Did nexenta really enhance the basic OpenSolaris, or is it just a lot of marketing speak? No one really wanted to answer that question.

  • How To Speed Up Adding Column To Large Table In Sql Server

    - by Chris
    I want to add a column to a Sql Server table with about 10M rows. I think this query would eventually finish adding the column I want: alter table T add mycol bit not null default 0 but it's been going for several hours already. Is there any shortcut to get a "not null default 0" column inserted into a large table? Or is this inherently really slow? This is Sql Server 2000. Later on I have to do something similar on Sql Server 2008.

  • Flex / Flash builder : no returning data using database

    - by Tristan
    Hello, i'm following some flex tutorials everything's working as wanted expected for one thing : When i use my function getServerByBrand($brand) there is no returned data into my datagrid and i don't know why because it uses the same schema as getAllserver() which is working . I don't know whether it's cause by the function itselft or the configuration in flash builder : protected function RechercheGSP_clickHandler(event:MouseEvent):void { getServerByBrandResult.token = dbClass.getServerByBrand(SearchInput.text); } Here's what i've got in Data/Services : getServerByBrand(brand : string) : Object And finally the function : public function getServerByBrand($brand) { $stmt = mysqli_prepare($this->connection, "SELECT DISTINCT * FROM $this->tablename where GSP_nom=? "); $this->throwExceptionOnError(); mysqli_stmt_execute($stmt); $this->throwExceptionOnError(); $rows = array(); mysqli_stmt_bind_result($stmt, $row->idServ, $row->GSP_nom, $row->IPserv, $row->port, $row->tickrate, $row->membre, $row->nomPays, $row->finContrat, $row->actif, $row->timestamp, $row->type, $row->jeux, $row->slot, $row->ipClient, $row->essai, $row->reussite, $row->echec, $row->valide, $row->email); while (mysqli_stmt_fetch($stmt)) { $row->timestamp = new DateTime($row->timestamp); $rows[] = $row; $row = new stdClass(); mysqli_stmt_bind_result($stmt, $row->idServ, $row->GSP_nom, $row->IPserv, $row->port, $row->tickrate, $row->membre, $row->nomPays, $row->finContrat, $row->actif, $row->timestamp, $row->type, $row->jeux, $row->slot, $row->ipClient, $row->essai, $row->reussite, $row->echec, $row->valide, $row->email); } mysqli_stmt_free_result($stmt); mysqli_close($this->connection); return $rows; } I tested the settings with configure return type and it tells me : "the operation returned a primitive "object". test settings : Parameters (brand) / Input type (String) / Value (woop) To conclude, there is no returned object at all. Do you see the problem ? Thanks

  • iPad: Mobile Safari, HTML5 <video>, and jquery transitions

    - by justinbach
    I'm building a simple proof-of-concept for an iPad-specific website that would use video transitions to bring users from section to section. For purposes of the proof of concept, each "section" is just an image with a semitransparent content text box positioned above it. There are just 2 sections, "home" and "contact", and they've got a transition video sandwiched between them via z-indexing. The idea for the proof of concept is that clicking on the "home" section causes it to disappear, followed by playback of the transition video, which (upon completion) disappears to reveal the "contact" section. Everything is working fine with this version of the demo on the iPad and on Safari for Windows and OS X. Here's the JS: var myVideo = document.getElementsByTagName('video')[0]; $('document').ready(function() { $('#home').click(function() { $(this).css('display','none'); myVideo.play(); myVideo.addEventListener('ended', function() { $('#transition').css('display','none'); }); }); }); What I'd like to do is use a jQuery fadeOut() effect to fade out the text box prior to starting the video when the "home" section is clicked. The code seems simple enough: $('document').ready(function() { $('#home').click(function() { $('#home-copy').fadeOut('slow', function() { $('#home').css('display','none'); myVideo.play(); myVideo.addEventListener('ended', function() { $('#transition').css('display','none'); $('#home-copy').fadeIn('slow'); }); }); }); }); and it's working exactly as desired on desktop versions of Safari. On the iPad, however, the text box fades out as expected and the home section disappears as well, but the video stubbornly refuses to start playing. I really don't know why this would be the case, but that's what's happening. I'd appreciate any advice you might have! Incidentally, here's the markup: <div id="main-container"> <div id="home-copy"> <h1>Lorem Ipsum Dolor Sit Amet</h1> <p>Donec blandit pharetra luctus. Nam at porttitor odio. Nullam sem orci, venenatis sed pharetra eget, commodo rhoncus quam. Ut euismod vehicula bibendum. Curabitur in magna ante, id fringilla lacus. Nullam id elit eget lacus feugiat porta. Nulla vitae orci vehicula risus sagittis egestas quis sed justo.</p> </div> <div id="home"> <img src="images/home.jpg" width="1152" height="720" /> </div> <video id="transition" src="video/home_to_contact_lo_res.mp4" preload width="1152" height="720"></video> <div id="contact"> <img src="images/contact.jpg" width="1152" height="720" /> </div> </div>

  • Basic video editor for AVCHD Lite files?

    - by davr
    I have a camera (Panasonic Lumix GF-1) that outputs "AVCHD Lite" files, 720p h264 in a MTS container. I saw this question that said Movie Maker in Windows 7 supports AVCHD...but I just tried, and unfortunately it does not support AVCHD Lite. Are there any free or inexpensive non-linear video editors (NLE) that can natively handle AVCHD Lite files, without requiring some 3rd party driver? If not, are there any 3rd party drivers that are especially stable? (In my experience they usually have some problems...I got AVCHD Lite loading into VirtualDub using a 3rd party plugin, but it's very slow and sometimes crashes, and seeking takes ages.

  • Routing audio from GSM module to a Bluetooth HandsFree device

    - by Shaihi
    I have a system with the following setup: I use: Windows CE 6 R3 Microsoft's Bluetooth stack including all profiles Motorola H500 The Audio Gateway service is up and running (checked through services list in cmd) GSM Module is functional - I am able to set outgoing calls and to answer calls. Bluetooth is functional - the A2DP profile plays music to Motorola headphones (can't remember the model right now) I want to hold a conversation using a headset device. I have included all Bluetooth components in the catalog. I pair the device using the Control Panel applet. When I press the button on the Motorla device to answer a call I get a print by the Audio Gateway: BTAGSVC: ConnectionEvent. BTAGSVC: SCOListenThread_Int - Connection Event. BTAGSVC: ConnectionEvent. BTAGSVC: SCOListenThread_Int - Connection Event. BTAGSVC: ConnectionEvent. BTAGSVC: A Bluetooth peer device has connected to the Audio Gateway. BTAGSVC: Could not open registry key for BT Addr: 2. BTAGSVC: The peer device was not accepted since the user has never confirmed it as a device to be used. So my questions are as follows: What do I need to do to pair the device with the Audio Gateway? Once my device is paired, do I need to set anything else up? (except for the GSM module of course)

  • Error when trying to connect to Jacorb naming service

    - by Dopyiii
    I'm hoping to get some help with this weird problem. We're running the Jacorb name server and I have a simple client that I'm using to try to connect and do awesome CORBA voodoo. The name server is running, but when I try to start my java app, I get a "Connection failure" error (org.omg.CORBA.COMM_FAILURE, minor code 201, "caused by java.net.ConnectionException: Connection refused: connect"). Here's the weird part. The error reports that it's trying to connect using the default port 900, but I'm passing in an argument to try to override the port number of the name service to match the one being used by the name server. My java command is like this: java -classpath . HelloClient -Djava.endorsed.dirs="bla bla bla" -Dorg.omg.CORBA.ORBClass=org.jacorb.orb.ORB -Dorg.omg.CORBA.ORBSingletonClass=org.jacorb.orb.ORBSingleton -DORBInitRef.NameService=corbaloc::localhost:2809/StandardNS/NameServer-POA/_root I also tried the parameters without the first capital D (I've seen it both ways and I don't know the difference). Now, if I put in -ORBInitialPort 2809, then the client does appear to try to connect, but then I get a corba.OBJECT_NOT_EXIST error. I could use any help or advise anyone has.

  • Can nginx be used as a reverse proxy for a backend websocket server?

    - by John Reilly
    We're working on a Ruby on Rails app that needs to take advantage of html5 websockets. At the moment, we have two separate "servers" so to speak: our main app running on nginx+passenger, and a separate server using Pratik Naik's Cramp framework (which is running on Thin) to handle the websocket connections. Ideally, when it comes time for deployment, we'd have the rails app running on nginx+passenger, and the websocket server would be proxied behind nginx, so we wouldn't need to have the websocket server running on a different port. Problem is, in this setup it seems that nginx is closing the connections to Thin too early. The connection is successfully established to the Thin server, then immediately closed with a 200 response code. Our guess is that nginx doesn't realize that the client is trying to establish a long-running connection for websocket traffic. Admittedly, I'm not all that savvy with nginx config, so, is it even possible to configure nginx to act as a reverse proxy for a websocket server? Or do I have to wait for nginx to offer support for the new websocket handshake stuff? Assuming that having both the app server and the websocket server listening on port 80 is a requirement, might that mean I have to have Thin running on a separate server without nginx in front for now? Thanks in advance for any advice or suggestions. :) -John

Background: I have a web-host who was running my website on Windows Server 2003 and SQL Server 2000. One of my webpages returned a result set from a stored procedure from the SQL server as xml. Below is the code: Stored Procedure: select top 10 1 as tag , null as parent , column1 as [item!1!column1!element] , column2 as [item!1!column2!element] from table1 for XML EXPLICIT ASP Page: index.asp Call OpenConn Set cmd = Server.CreateObject("ADODB.Command") With cmd .ActiveConnection = dbc .CommandText = "name of proc" .CommandType = adCmdStoredProc .Parameters.Append .CreateParameter("@RetVal", adInteger, adParamReturnValue, 4) .Parameters.Append .CreateParameter("@Level", adInteger, adParamInput, 4, Level) End With Set rsItems = Server.CreateObject("ADODB.Recordset") With rsItems .CursorLocation = adUseClient .CursorType = adOpenStatic .LockType = adLockBatchOptimistic Set .Source = cmd .Open Set .ActiveConnection = Nothing End With If NOT rsItems.BOF AND NOT rsItems.EOF Then OutputXMLQueryResults rsItems,"items" End If Set rsItems = Nothing Set cmd = Nothing Call CloseConn Sub OpenConn() strConn = "Provider=SQLOLEDB;Data Source=[hidden];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" Set dbc = Server.CreateObject("ADODB.Connection") dbc.open strConn End Sub Sub CloseConn() If IsObject(dbc) Then If dbc.State = adStateOpen Then dbc.Close End If Set dbc = Nothing End If End Sub Sub OutputXMLQueryResults(RS,RootElementName) Response.Clear Response.ContentType = "text/xml" Response.Codepage = 65001 Response.Charset = "utf-8" Response.Write "" Response.Write "" While Not RS.EOF Response.Write RS(0).Value RS.MoveNext WEnd Response.Write "" Response.End End Sub Present: All was working great, until my host upgraded to Windows Server 2008 and SQL Server 2008. All of the sudden I was getting results like this: From Browser: From View Source: However, I found that if I use a DSN connection strConn = "DSN=[my DSN Name];User Id=[hidden];Password=[hidden];Initial Catalog=[hidden];" it works perfectly fine! My current host is not going to support DSN any longer, but that's out of scope for this issue. Someone told me to use an ADO.Stream object instead of a Recordset object, but I'm unsure how to implement that. Question: Has anyone run into this and found a way to fix it? What about that ADO.Stream object, can someone help me with a sample that would fit my code?
