  • Matte or non-widescreen laptop? Do they exist?

    - by Alan Harris-Reid
    Does anyone know of any matte-screen laptops being sold now (15.6 or 17") in the UK? All I can find is the Dell Vostro 3500/3700 range, but there is a premium of around £200 over the price of their Inspiron range (for the 17" model), and I find it hard justifying the extra cost just to have a matte screen. I do not like glossy screens, but it seems the laptop industry has gone the way of "glossy is better - let's get rid of matte". I have read and heard from other developers that as long as there are no strong light sources to reflect off the screen, one can soon get used to a glossy screen, but I am yet to be convinced. I would also be interested if anyone knows of any non 16:9 screen laptops. I find this ratio too wide and not high-enough for the work I do. 16:10 or lower would be better. Any opinions would be appreciated. Alan

  • Does laser printer use toner when switched on/off?

    - by Alan Harris-Reid
    I have recently purchased a HP LaserJet M175nw laser printer which goes into sleep-mode after 10 minutes of non-use. I know sleep-mode uses a very small amount of power, but the flashing light on the control panel is driving me nuts! I know I can turn-off the printer via. the on/off button, but when it is turned-on manually, there is some whirring sound which I guess might be the machine warming-up. My question is... Is any toner used during this warm-up (or cleaning) cycle? Am I better-off keeping the printer in sleep mode, or is it ok to turn off manually? TIA Alan

  • Excluding certain file types in wget

    - by Alan Spark
    I have been using wget for a while now to mirror files from an ftp server to a local folder. My wget command is as follows: wget -mirror -w 1 -p -nH -P /var/www/ ftp://my-ftp-server However, I just noticed that it is copying over a .listing file for every folder that it visits. So, even if nothing has been changed on the ftp server, a .listing file will always be copied. My understanding is that the .listing file is created when wget opens the ftp session. Is there a way to avoid this? I've tried the -R option (e.g. -R .listing) but this didn't help. See: http://www.gnu.org/software/wget/manual/wget.html#Recursive-Accept_002fReject-Options Thanks, Alan

  • How can I persist certificates in Java's cacerts?

    - by Alan Spark
    We need to have a certificate in Java's cacerts keystore for one of our servers that is authenticated by LDAP. We are using Ubuntu server. We have successfully done this by updating the cacerts file in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/security but occasionally a Java update is installed and the cacerts file seems to be getting replaced by a default one that doesn't contain our changes. This doesn't happen very often but it is becoming a bit of a pain when it does happen. Is there a better way of adding things to cacerts so that they don't get lost when a Java update happens? Thanks, Alan

  • Syncing Large Directories/Filesystems using USB Drive [closed]

    - by Alan Lue
    Does anyone have a solution for syncing large directories/filesystems using just a USB flash drive (and specifically without using a network connection)? The objective is simply to sync a user directory between two computers. The contents of the user directory could amount to a large quantity of data—say, a quantity larger than could be stored on any single USB drive—but the aggregate size of changes that must be propagated by a single sync could easily fit on a USB drive. As an example, suppose a user directory is already synchronized between a desktop and a laptop computer. Here's a use case: Some changes are made in the user directory on the desktop. We mount a USB drive onto the desktop and copy whatever changes need to be applied to the laptop user directory in order to synchronize the desktop and laptop user directories. We now mount the USB drive onto the laptop and apply the changes. The desktop and laptop user directories are now synchronized. Any ideas? Alan

  • Windows XP SP3 dissapearing mapped drives

    - by Alan Spark
    I am running Windows XP Pro SP3 and I've got a few shares on my NAS that are mapped to reconnect automatically. I can access the drives soon after starting windows but after a period of inactivity I get the error "The local device name is already in use". This cannot be remedied until I restart the computer - I've tried disconnecting and re-mapping without success. This was working fine until I recently reinstalled Windows and I'm not sure what is going on. Any help would be greatly appreciated. Thanks, Alan

  • format dojo DataGrid header row

    - by Alan Seiden
    I want to assign a background color to my programmatically created Dojo DataGrid's header row. I've tried to override the defaults by adding .dojoxGridHeader or .dojoxGrid-Header to my style sheet, but these have no effect. Is there another way, such as with a Dojo event or property? If my style sheet is the only way to go, am I using the wrong class? Thanks! Alan

  • CDN Rerouting on 404 (file not yet in synch with original storage)

    - by Alan Ristic
    Here is the problem. I've setup my app(on EC2) to store uploaded images directly on Amazon S3. I'd like to be able to serve static files(cdn) from my 'home' server so I wrote script that does sync from S3. But there is a window of (at least) one minute in synch. Now I see two solutions on the problem of pics not been available on 'home' server here: 1.I write script on EC2 (where the app resides) to fetch from DB pics that have status of "not-yet-synch", which is default state when user uploads picture. The script then does a ping to picture and if it gets OK response, updates DB from "not-yet-synch" to "synch". 2.Prefered solution would be to let apache (in this case) redirect request for an image if it sees 404 (e.g. doesent find image requested) to S3. This way I wouldn't need script from solution 1. So what approach do you suggest I take in solving this redundancy problem? Or what is practice in production environments? To further clarify; I'd like so serve images first from 'home' server, if that fails serve them from S3. Tnx, Alan

  • Unit testing "hybrid" WPF/Silverlight controls

    - by Alan Mendelevich
    I'm starting a new WPF/Silverlight custom control project and wanted to do unit testing on this one. However I'm a little confused about how to approach this. This control would be based on the same codebase for both WPF and Silverlight with minor forking using #ifs and partial classes to tame the differences. I guess I could write unit tests for WPF part with NUnit, MSTest, xUnit, etc. and for the Silverlight part with Silverlight Unit Test Framework but this doesn't sound very elegant to me. I'd have to either ignore testing identical code on one of the platforms and test only differing parts (which is not very trustworthy) or rewrite tests for 2 frameworks (which is annoying). Is this the right way to go? I'm wondering if there's some guidance, articles, tutorials out there on how to approach this task. Any pointers?

  • Regex with all optional parts but at least one required

    - by Alan Mendelevich
    I need to write a regex that matches strings like "abc", "ab", "ac", "bc", "a", "b", "c". Order is important and it shouldn't match multiple appearances of the same part. a?b?c? almost does the trick. Except it matches empty strings too. Is there any way to prevent it from matching empty strings or maybe a different way to write a regex for the task.

  • Converting items in Visual Studio project from "links" to copied files

    - by Alan Mendelevich
    Hi, I have a Visual Studio (2008) project where I have some files added as links (through Add Existing Item-Add As Link). Suppose I want to copy this project somewhere else (give it to another developer, release source code, etc.) and I would like to "convert" all these links to actual copies of these files. Is this possible? How can I do this in VS or is there some 3rd party utility to do that? Thanks.

  • Determining if object is visible and clickable

    - by Alan Mendelevich
    I'm looking for ways to effectively determine if a control is actually visible and clickable. I mean beyond checking Visibility property of the object. I can check RenderSize and that would be [0,0] if any of the parent elements is collapsed. So this is simple too. I can also traverse up the visual tree and see if Opacity of all elements is set to 1. What I don't know how to check nicely are these scenarios: The object is obstructed by some other object. Obviously it's possible to use FindElementsInHostCoordinates() and do computations to find out how much these objects obstruct but this could be an overkill. I can also make a "screenshot" of the object in question and "screenshot" of the whole page and check if pixels where my object should be match the actual object pixels. That sounds like an overkill too. The object is obstructed by a transparent object that still "swallows" clicks (taps). The workarounds for the first problem could still fail in this scenario. Any better ideas? Do I miss something? Thanks!

  • Cisco IPSec, nat, and port forwarding don't play well together

    - by Alan
    I have two Cisco ADSL modems configured conventionally to nat the inside traffic to the ISP. That works. I have two port forwards on one of them for SMTP and IMAP from the outside to the inside this provides external access to the mail server. This works. The modem doing the port forwarding also terminates PPTP VPN traffic. There are two DNS servers one inside the office which resolves mail to the local address, one outside the office which resolves mail for the rest of the world to the external interface. That all works. I recently added an IPSec VPN between the two modems and that works for every thing EXCEPT connections over the IPSec VPN to the mail server on port 25 or 143 from workstations on the remote lan. It would seem that the modem with the port forwards is confusing traffic from the mail server destined for a machine on the other side of the IPSec VPN for traffic that should go back to a port forward connection. PPTP VPN traffic to the mail server is fine. Is this a scenario anybody is familiar with and are there any suggestions on how to work around it? Many thanks Alan But wait there is more..... This is the strategic parts of the nat config. A route map is used to exclude the lans that are reachable via IPSec tunnels from being Nated. int ethernet0 ip nat inside int dialer1 ip nat outside ip nat inside source route-map nonat interface Dialer1 overload route-map nonat permit 10 match ip address 105 access-list 105 remark *** Traffic to NAT access-list 105 deny ip 192.168.1.0 0.0.0.255 192.168.9.0 0.0.0.255 access-list 105 deny ip 192.168.1.0 0.0.0.255 192.168.48.0 0.0.0.255 access-list 105 permit ip 192.168.1.0 0.0.0.255 any ip nat inside source static tcp 192.168.1.241 25 interface Dialer1 25 ip nat inside source static tcp 192.168.1.241 143 interface Dialer1 143 At the risk of answering my own question, I resolved this outside the Cisco realm. I bound a secondary ip address to mail server 192.168.1.244, changed the port forwards to use it while leaving all the local and IPSec traffic to use 192.168.1.241 and the problem was solved. New port forwards. ip nat inside source static tcp 192.168.1.244 25 interface Dialer1 25 ip nat inside source static tcp 192.168.1.244 143 interface Dialer1 143 Obviously this is a messy solution and being able to fix this in the Cisco would be preferable.

  • Architectural advice - web camera remote access

    - by Alan Hollis
    I'm looking for architectural advice. I have a client who I've built a website for which essentially allows users to view their web cameras remotely. The current flow of data is as follows: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Ftp connection is enabled for the cameras ftp user. Web camera opens ftp connection to server. Web camera begins taking photos. Web camera sends photo to ftp server. On image url request: Server reads latest image on hard drive uploaded via ftp for camera. Server deleted any older images from the server. This is working okay at the moment for a small amount of users/cameras ( about 10 users and around the same amount of cameras), but we're starting to worrying about the scalability of this approach. My original plan was instead of having the files read from the server, the web server would open up an ftp connection to the web server and read the latest images directly from there meaning we should have been able to scale horizontally fairly easily. But ftp connection establishment times were too slow ( mainly due to the fact that PHP out of the ox is unable to persist ftp connections ) and so we abandoned this approach and went straight for reading from the hard drive. The firmware provider for the cameras state they're able to build a http client which instead of using ftp to upload the image could post the image to a web server. This seems plausible enough to me, but I'm looking for some architectural advice. My current thought is a simple Nginx/PHP/Redis stack. Web camera issues post requests of latest image to Nginx/PHP and the latest image for that camera is stored in Redis. The clients can then pull the latest image from Redis which should be extremely quick as the images will always be stored in memory. The data flow would then become: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Camera is sent an http request to start posting images to a provided url Web camera begins taking photos. Web camera sends post requests to server as fast as it can On image url request: Server reads latest image from redis Server tells redis to delete later image My questions are: Are there any greater overheads of transferring images via HTTP instead of FTP? Is there a simple way to calculate how many potential cameras we could have streaming at once? Is there any way to prevent potentially DOS'ing our own servers due to web camera requests? Is Redis a good solution to this problem? Should I abandon PHP/Ngix combination and go for something else? Is this proposed solution actually any good? Will adding HTTPs to the mix cause posting the image to become too slow? Thanks in advance Alan

  • ASP.NET MVC and mixed mode authentication

    - by Alan T
    Hi All I have a scenario whereby I require users to be able to authenticate against an ASP.NET MVC web application using either Windows authentication or Forms authentication. If the user is on the internal network they will use Windows authentication and if they are connecting externally they will use Forms authentication. I’ve seen quite a few people asking the question how do I configure an ASP.NET MVC web application for this, but I haven’t found a complete explanation. Please can someone provide a detailed explanation, with code examples, on how this would be done? Thanks. Alan T

  • SQLite data-types

    - by Alan Harris-Reid
    Hi there, When creating a table in SQLite3, I get confused when confronted with all the possible datatypes which imply similar contents, so could anyone tell me the difference between the following data-types? INT, INTEGER, SMALLINT, TINYINT DEC, DECIMAL LONGCHAR, LONGVARCHAR DATETIME, SMALLDATETIME Is there some documentation somewhere which lists the min./max. capacities of the various data-types? For example, I guess smallint holds a larger maximum value than tinyint, but a smaller value than integer, but I have no idea of what these capacities are. Any help would be appreciated.

  • Powershell: Setting values of a filtered array

    - by Alan T
    Hi All I want to read in a csv file, filter it based on the values of two of the fields and set the value of another field. Here's a simple example of what I'm trying to achieve: c:\somefile.csv contents: firstField,secondField,thirdField 1,2,"somevalue" 2,2,"avalue" 3,1,"somevalue" #Import file into array $csv = Import-Csv c:\somefile.csv # Where secondField = 2 and thirdField = "someValue" set thirdField = "anotherValue" $csv | where {$_secondField -eq 2 -and $_.thirdField = "somevalue"} | <set value of thirdField = "anotherValue"> How can I do this. As you can see, from the example about, I can read in and filter the array. But I don't know how to then set the value of the thirdField. I tried set-itemproperty but got the error: "The WriteObject and WriteError methods cannot be called after the pipeline has been closed". Any advice on how to achive this would be appreciated.

  • CSS file pathing problem

    - by Alan Harris-Reid
    Hi there, When designing a HTML template in my favorite editor (TextPad at the moment) I can view my code in a browser by pressing F11 or the appropriate toolbar button. I have my common css rules in a separate file so my HTML contains the code: <link rel="stylesheet" href="commoncss.css" type="text/css"> This works when the .css file is in the same folder as the .html file, or if I fully path the .css file in the href property, eg. ///c:/mycssfolder/commoncss.css However, in a 'live' situation I want the .css file to reside in a common folder which is accessible from a number of .html files (eg. href='css/commoncss.css', where the css folder is configured at web-server level). How can I achieve this design vs. live dilemma without copying css file to all .html folders (and all the maintenance headaches that comes with it)? I am using Python 3.1 with Jinja2, but I guess this problem is applicable across any language and template-engine. Any help would be appreciated. Alan

  • Number of lines in csv.DictReader

    - by Alan Harris-Reid
    Hi there, I have a csv DictReader object (using Python 3.1), but I would like to know the number of lines/rows contained in the reader before I iterate through it. Something like as follows... myreader = csv.DictReader(open('myFile.csv', newline='')) totalrows = ? rowcount = 0 for row in myreader: rowcount +=1 print("Row %d/%d" % (rowcount,totalrows)) I know I could get the total by iterating through the reader, but then I couldn't run the 'for' loop. I could iterate through a copy of the reader, but I cannot find how to copy an iterator. I could also use totalrows = len(open('myFile.csv').readlines()) but that seems an unnecessary re-opening of the file. I would rather get the count from the DictReader if possible. Any help would be appreciated. Alan
