• How can I see the structure of a webpage inline?

  - by Coldblackice

  How can I see a webpage's structure "inline" with the visual representation of the actual page, all at once? I'm trying to understand HTML layout better, but it's hard to get a feel for it, even having the source open on a separate monitor, because there's just so much expansive and miscellaneous code. I suppose I could sift through it, clean it up, and set up some type of custom collapsible tree system, but that would take too long for the amount of pages I'd like to get a quick view of the layout/structure of. For reference, I'm using Firefox for my internet browsing.

• Strategy in storing ad-hoc numbers/constants?

  - by Jiho Han

  I have a need to store a number of ad-hoc figures and constants for calculation. These numbers change periodically but they are different type of values. One might be a balance, a money amount, another might be an interest rate, and yet another might be a ratio of some kind. These numbers are then used in a calculation that involve other more structured figures. I'm not certain what the best way to store these in a relational DB is - that's the choice of storage for the app. One way, I've done before, is to create a very generic table that stores the values as text. I might store the data type along with it but the consumer knows what type it is so, in situations I didn't even need to store the data type. This kind of works fine but I am not very fond of the solution. Should I break down each of the numbers into specific categories and create tables that way? For example, create Rates table, and Balances table, etc.?

• PHP APC - Why is loading cached array op codes slow?

  - by Aaron Kreider

  I'm using APC to reduce my loading time for my PHP files. My files load very fast, except for one file where I define more than 100 arrays. This 270 kb file takes 200 ms to load. The rest of the files are full of objects, methods, and functions. I'm wondering: does OP code caching not work as well for arrays? My APC cache should be big enough to handle all of my classes. Currently 40% of my cache is free. My hit rate is 99%. apc.shm_size=32 M apc.max_file_size = 1M apc.shm_segments= 1 APC 3.1.6 I'm using PHP 5.2, Apache 2, and Windows Vista.

• Getting Synergy+ to work with Windows 7 64bit and Windows XP 32bit?

  - by john crisp

  My Windows XP box is Dell 4550 dimension. Windows 7 box is Home Premium. Synergy + installs fine on the Windows 7box, but using Windows xp as the client, it won't work? Do I need to disconnect the vga connection from my monitor and control entirely from the win7 dvi connection? In setting up ( links ) on Windows 7 as the server, I have NO way of inputing info? The setup on the Windows xp box is simple and does so OK, but I can't connect to the Windows xp box! It must be the vga connection on the Windows XP box. In order to use both machines, I have to turn one off and the other on. Hence-the VGA is needed on Windows XP. Any info/help most appreciated.

• capture nimbuzz traffic

  - by lurscher

  I need to capture all the traffic, specially during login, between nimbuzz pc client and nimbuzz server. The reason is that i need to debug outgoing packets at login that mark the user visibility status in order to reproduce them in a in-house XMPP client application I've tried doing this with wireshark, but i seem to be pretty helpless with this tool. Also, the packets i've been able to see are all before the SASL negotiation happens, after that, i cannot see the xml packets being exchanged any help for how to achieve this task is greatly appreciated (preferably on Windows, since there is no nimbuzz client for linux, in any case i can install one in a VM and monitor the traffic between the VM instance in the linux host)

• How to effectively draw on desktop in C#?

  - by Lazlo

  I want to draw directly on the desktop in C#. From searching a bit, I ended up using a Graphics object from the Desktop HDC (null). Then, I painted normally using this Graphics object. The problem is that my shapes get lost when any part of the screen is redrawn. I tried a While loop, but it actually ends up drawing as fast as the application can, which is not the update rate of the desktop. Normally, I would need to put my drawing code in a "OnPaint" event, but such thing does not exist for the desktop. How would I do it? Example code: http://stackoverflow.com/questions/1536141/how-to-draw-directly-on-the-windows-desktop-c

• How to find modal dialog opener from javascript?

  - by yapiskan

  I have a page that opens a modal dialog. After the operations done on dialog I want to refresh the opener page. But when I open the popup by using "openDialog" I cannot access to the opener by using window.opener on popup page. It appears "undefined" when I wanted to access. (I dont want to use "popup" method in this case. I want it to be a dialog by the way. using "popup" is my second plan.) What is the best practice to get rid off this issue?

• Lock Windows keyboard and mouse but still display screen normally

  - by Stephen Lacy

  I'm using windows 7, I have a dual monitor display. It displays important information related to the business, I'd rather that random users that walk in can't just walk over to it and start using the computer with the same access rights as the user the monitoring software is running as. What I would like is if any time someone presses a button on the keyboard including alt-ctrl-delete all that would appear is a dialog asking for a password. Then I can click cancel and it will return to showing the data I want displayed. ClearLock doesn't work I tried it btw

• Is it my motherboard?

  - by jarodrussell

  Early this week my home server (a Linux machine) threw a kernel panic. Yesterday is happened a couple of times. Then all of a sudden, when I plugged a USB stick in to run a memory test, the monitor stopped coming on. Now whenever I turn it on, the system gets power...I heard the drives spin, I see the processor fan spin, and the hard drive light comes on...but nothing happens. I put a video card in the AGP slot, but still nothing. The light on the power button that usually comes on stopped coming on. I took the memory out to see if it would beep, but nothing beeped. It's like it's getting power, but it's not coming on. Does this sound like a motherboard problem to anyone else? I think it is, but a second opinion would be greatly appreciated. Thanks.

• Monitoring server room temperature

  - by user640

  I have a small server room with its own AC unit. Recently, the AC died, and the temperature increased from 70 F to 90 F. We rarely go in this room, so I was lucky that someone happened to notice that the fans were running a lot louder than normal as they walked past the door. It looks like I need a way to be notified when the temperature in that room gets too hot. What tools are you using to monitor the temperature in your server room? How does this tool notify you of a problem (email, SNMP, etc). Note: I've read this question on server temperature, but I'm interested in the whole room, not just the inside of a server case. Edit: Thanks for all the great responses so far! Many of these products measure much more than just temperature. What else should I be looking at and why?

• How to get started setting up IP security cameras

  - by dave

  I have just finished renovating my house. As part of the job, I have cat6 cable run through the house, including two external plugs. All cables terminate in the same location. My rough plan is to plug two IP cameras to monitor the front and rear, run POE from a central router to the two external cameras, plug my PC into the same router and run magic software X. Any machine plugged into the router or wirelessly connection should then be able to get a live feed and alerts based on motion detection. That's the plan, but I'm not sure how possible it is. What hardware to get and what monitoring software to get. Has anyone does something similar? What were your experiences?

• Rsync over NFS with QoS: How to view real transfer speed?

  - by Ian Mackinnon

  We have a bandwidth limit between a Linux server and a NAS, created using 'tc' with an IP filter. When writing to an NFS mount of the NAS, rsync claims a very high transfer speed for each file and then waits a long time before acknowledging that everything has finished. The total time taken is consistent with the QoS limit and the time taken by the same transfer over FTP. Why does the write to the NFS mount report higher transfer speeds than are actually happening over the network? How can I monitor the actual bandwidth of the transfer?

• Integrate code generation with eclipse c++ build

  - by Dan

  Hi, I am using Eclipse for C++ development on windows. I have also written a code generator that take an xml file and produces several C++ files. The project I am working on is currently setup to use the internal builder. What I would like to do is to run the code generator as part of the build process. My problem is that I haven't been able to find a way to make Eclipse identify that the files are present (or have been updated) without 'Refeshing' the project. So although I can run the code generator as a pre-build step, the files generated aren't guaranteed to be included in the build. Does anybody know whether there is a way to make Eclipse do a refresh after the pre-build step or something to that effect, using the internal builder? Thanks

• Update JProgressBar from new Thread

  - by Dacto

  How can I update the JProgressBar.setValue(int) from another thread? My secondary goal is do it in the least amount of classes possible. Here is the code I have right now: **Part of the main class....** pp.addActionListener( new ActionListener(){ public void actionPerformed(ActionEvent event) { new Thread(new Task(sd.getValue())).start(); } }); public class Task implements Runnable{ int val; public Task(int value){ this.val = value; } @Override public void run() { for (int i=0; i<=value; i++){ //Progressively increment variable i pbar.setValue(i); //Set value pbar.repaint(); //Refresh graphics try{Thread.sleep(50);} //Sleep 50 milliseconds catch (InterruptedException err){} } } } pp is a JButton and starts the new thread when the JButton is clicked. pbar is the JProgressBar object from the Main class. How can I update its value?(progress) The code above in run() cannot see the pbar.

• Reliability of S.M.A.R.T.?

  - by Mark

  I've been using ActiveSmart to monitor my hard-drives health for a few weeks now, and its telling me my brand new 1.5 TB hard-drive is half-dead already. About on-par with one of my hard-drives which I know is at least half dead because I've been having some read errors and heard ticking noises. Now I haven't actually noticed any problems with my 1.5 TB drive; should I be concerned that it's going to crap out on me too? Or could ActiveSmart be giving a mis-diagnosis because I use it a lot or something (I've used up 795 GB in the 2 and a half weeks I've had it). The events that ActiveSmart has been catching is "Hardware ECC recovered". Maybe these new fangled super big hard-drives somehow rely on ECCs to squeeze out the extra space, but this isn't actually a cause for concern?

• Media center consumes all available memory when attempting to play music off of a server

  - by RCIX

  I have Windows 7 Ultimate, and recently, when i try to play a song off of my Twonky Media Server/Windows Media Connect (based on an HP WHS with an Atom), it plays choppily. When i open Resource Monitor, it shows that after ordering the music to play, memory usage rapidly spikes to consume most, if not all, of the available memory on my system (excluding a couple hundred megabytes in standby). Why does it do this and is there anything i can do to stop it? Edit: it happens when I attempt to browse the server's music, not just when i play music. Edit 2: the "ehshell" process is what consumes the memory, appears to me something specific to media center. Moreover, the ehshell process doesn't die in this case. Edit 3: It only happens when browsing my Twonky library, and not my Windows Media Connect.

• Sharing soundcard to network.

  - by zerkms

  Let's suppose I have a laptop (L) and desktop PC (D), both with Windows 7 onboard. It is SB X-Fi extreme soundcard with rather good 5.1 home theater connected. But it is not comfortable to watch video sitting on the sofa from my desktop (sofa is in the center of the room and D is in the corner), even though it is 23" monitor. So I'm watching everything from the laptop. So the question - is it possible somehow to "share" soundcard from D to L, so I will watch the video from notebook and listen the sound from the 5.1? L and D are connected via wi-fi (fast enough).

• How to play from mic to speakers in Ubuntu Karmic?

  - by vava

  Ok, I have a silly problem. I have few bluetooth headsets lying around and I want to make DYI baby monitor out of them. All I need is for some application to listen to the mic and send it to the speakers. Loopback (even though it doesn't work) is not good enough, it'll send sound from the mic to the speakers in the same device but I need it to go across devices. So does anyone know some application that can do that? I'm looking for something small and easy to use, not jackd or similar.

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• AutoComplete and VS2010 Internal WebDevServer caching ?

  - by Renshai

  Ok this is a simple setup: DB has a view with personnel who have not been added to the system. The AutoComplete dynamically lists a numeric column field from the view. (Using Linq2SQL) (with autotracking off) Once this number is consumed - a refresh is done on the sqlserver's view. The Problem: This number still shows up in the Autocomplete UNTIL the VS WebDev Server is closed. Question: Why is the WebDev caching the data? I have tried turning off viewstate of the textbox, turned off caching on the autocompleteextender, to no avail. Any help please ...
