• Apache stops responding to http requests -- https continues to work

  - by Apropos

  Okay. Very strange problem that I'm having here. I just recently updated to Apache 2.4.2 from 2.2.17, mostly to try to get name-based SSL VirtualHosts working (although they should have been working on 2.2.17). Server is Win2008 R2 (so x64 by definition) running with PHP 5.4.3 and MySQL 5.1.40 (outdated, I know). When I launch the server, it initially works fine. Responds to all requests, VirtualHosts all in order. However, after an uncertain amount of time (appears to only take a few minutes for the most part, but sometimes takes hours), it stops responding to regular HTTP requests (on any VirtualHost). HTTPS continues to work. No errors in the log, and nothing in the access logs when I attempt to connect. I'm having a hard time finding the source of this error given its intermittent nature. When removing all SSL-based VirtualHosts, it seemingly increased stability (still responding to HTTP requests twelve hours later). This could be mere coincidence, though. Entirety of SSL VirtualHost is as follows, should there happen to be a problem with it. <VirtualHost *:443> DocumentRoot "C:\Server\www\virtualhosts\mysite.net" ErrorLog logs/ssl.mysite.net-error_log CustomLog logs/ssl.mysite.net-access_log common env=!dontlog SSLEngine on SSLProtocol all -SSLv2 SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM SSLCertificateFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.crt SSLCertificateKeyFile C:/Server/bin/apache/apache2.4.2/conf/ssl/server.key SSLCertificateChainFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/sub.class1.server.ca.pem SSLCACertificateFile C:/Server/bin/apache/Apache2.4.2/conf/ssl/ca.pem </VirtualHost> Any ideas what I'm missing?

• Computer "Server"

  - by user328379

  so at home we had the idea of instead of buying 3 different pc's we would somehow create a "server" for the computers where a cable would come to our screens and keyboard and mouses, so the actual pc was somewhere else in the house with all the others. Does such a thing exist? And is it possible to have such a thing for high performance workflow? (Compiling, High-End Games, just as if it was a separate pc )

• Configuring two nearby WLANs: should I use the same ssid?

  - by Rory

  I'm configuring a home network for basic internet use (ie don't really need connectivity between workstations on the network). My brick walls mean a single wireless router doesn't provide good coverage throughout the house, so I have purchased two powerline adapters and now have the incoming modem/wireless router at one end of the house plugged into a powerline adapter, and at the other end of the house the other powerline adapter plugged into another wireless router. Currently the two wireless networks have different ssids. (The powerline adapters only do power-Ethernet; they're not wireless access points themselves.) This works well, except when I move between rooms and would ideally like my devices (iPad, phones, laptops) to switch from the weak to the strong signal. Sometimes there's enough signal that they hold on to the weak connects instead of switching to the strong one. Should I name the two networks the same ssid, and if so what is the actual effect? Do the signals get confused, is the bandwidth affected, will this help my devices seamlessly move from one to the other, or is the ssid just a cosmetic thing that actually doesn't have any impact on this situation? Are there any other settings that I should configure to make my setup optimal?

• VIDEO Streaming - How to output the video timestamp?

  - by Emmanuel Brunet

  I would like to backup an ASF video stream with the time stamp (I mean the original recording date/time) on the output stream ? Usage I convert / store my video using the mkv format (Matroska) with libx264 (video) and aac (audio) codecs. Assume the IP camera webcam user account is account, the password password $ ffmpeg -i http://admin:alpha1237@webcam/videostream.asf -c:v libx264 -s 768X432 -crf 13 -b:v 2500K -pix_fmt yuv420p -c:a libfdk_aac output.mkv This works fine on a tenvis JPT3815W camera How to I need to get the video timestamp available for display as a subtitle or other meta data field managed by standard video players, and ideally to be able to hide it or not during video reading. Does anybody knows how to achieve that ? Thanks in advance for your help.

• ffserver-2.2 - streaming an ASF video as Webm output with ffserver on Debian 7.5

  - by Emmanuel Brunet

  I'm trying to stream an IP webcam ASF live stream to a ffserver to output a webm video format.

• Cannot browse network shares in Windows Explorer, but paths are still accessible

  - by Jeff Lockhart

  Windows Explorer has somehow corrupted itself and I'm not sure how to fix this problem. My Windows installation has been in use for a few years with network shares setup and working. Recently, I noticed that a program that I use to save network share paths to a database was no longer opening the explorer window to browse the path. It usually opens to the last path saved, but now it was just not opening at all. When I go to Windows Explorer to browse the network share directly, I get the error \\SERVER is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network provider name is invalid. The network shares are just shares on the server itself (once saved to the database, they're used on the server as well as clients to reach files). The strange thing is, the files are still accessible from the program that uses them if I type the network share path in manually. So it is only a problem with Windows Explorer browsing the path. The reason I think there is some sort of configuration or setting, possibly in the registry, corrupted is that when the problem first manifest itself, I was somehow able to open an explorer window to a network share path, but the breadcrumb in the address bar did not function properly. It duplicated the share name folder at the top of the breadcrumb stack and when I clicked the second of the duplicated share folder, it crashed explorer.exe. I haven't been able to browse any network share path since this happened. I have tried using the IP address directly \\192.168.1.# as well as \\localhost and neither of those work either. I have tried running sfc /scannow and it did not find any errors. I tried ipconfig /flushdns and this made no difference. Attempting to map the network share to a drive fails using either the explorer GUI or net use command. Is there some way to reset Windows Explorer somehow to resolve this? I'd really like to avoid reinstalling Windows entirely if I can.

• BBDB/OrgMode Workflow to store additional information

  - by Matth

  What is the best strategy to establish links and reverse links to my contacts stored in BBDB? My Outline is similar to this: * Projects ** a ** b -> link to contact? ** c * Notes ** 2014-04-02 Meeting with Contact A -> link to contact? How can I create a workflow so that all references to this contact are shown, once I open this contact in BBDB? Currently I use a "hack" where I manually enter links to the entries in the "Notes" field of that entry. But as it is not possible to inclide org-mode outlines in the "Notes" filed, it is an appalling list unusable links.

• Does a router have a receiving range?

  - by Aadit M Shah

  So my dad bought a TP-Link router (Model No. TL-WA7510N) which apparently has a transmitting range of 1km; and he believes that it also has a receiving range of 1km. So he's arguing with me that the router (which is a trans-receiver) can communicate with any device in the range of 1km whether or not that device has a transmitting range of 1km. To put it graphically: +----+ 1km +----+ | |------------------------------------------------->| | | TR | | TR | | | <----| | +----+ 100m+----+ So here's the problem: The two devices are 1km apart. The first device has a transmitting range of 1km. The second device only has a transmitting range of 100m. According to my dad the two devices can talk to each other. He says that the first device has a transmitting and a receiving range of 1km which means that it can both send data to devices 1km away and receive data from devices 1km away. To me this makes no sense. If the second device can only send data to devices 100m away then how can the first device catch the transmission? He further argues that for bidirectional communication both the sender and the reciver should have overlapping areas of transmission: According to him if two devices have an overlapping area of transmission then they can communicate. Here neither device has enough transmission power to reach the other. However they have enough receiving power to capture the transmission. Obviously this makes absolutely no sense to me. How can a device sense a transmission which hasn't even reached it yet and go out, capture it and bring it back it. To me a trans-receiver only has a transmission power. It has zero receiving power. Hence for two devices to be able to communicate bidirectionally, the diagram should look like: Hence, from my point of view, both the devices should have a transmission range far enough to reach the other for bidirectional communication to be possible; but no matter how much I try to explain to my dad he adamantly disagrees. So, to put an end to this debate once and for all, who is correct? Is there even such a thing as a receiving range? Can a device fetch a transmission that would otherwise never reach it? I would like a canonical answer on this.

• Windows 8 not booting from DVD while trying to install in a Ubuntu 14.04 system

  - by Tom

  Currently my system runs on Ubuntu 14.04. Yesterday, I deleted and formatted the partition(C drive) as NTFS in which Windows 7 was installed because Windows 7 was not booting for more than a week. I have a Windows 8 disk and it was able to boot from that disk when there was Windows 7 on my system. After the formatting of C drive yesterday, I tried to install Windows 8 by booting from the disk. Unfortunately, this time no booting happened from the disk. So I pressed F2 during the system start up and checked Boot Device Priority, Optical Drive has the first priority there. So why Windows 8 didn't boot from the disk ? I need to install Windows 8 too in my system without doing any damage to Ubuntu 14.04. How can I do it ?

• Windows 7 not booting up and stuck at startup repair

  - by mikimr

  I've been having issues with Windows 7 Home Premium on a Lenovo laptop. At first, it would not start up normally at all. I started it in Safe Mode, where I disabled all non-MS services and tried again to no avail. It then goes into Startup repair where it failed several times. I tried copying the original registry settings, still the same. I resorted to booting with an Ubuntu DVD, where I ran the boot-repair, where it is supposed to correct the Windows boot. No luck. I used Win7 DVD to start up from there, where I had the option to install or repair. I chose the repair, got into command prompt, ran chkdsk /i /r, where it found 3 unreadable segments, went through the 2nd step without issues, and the 3rd step completed with some errors (can't recall the exact errors). When I restarted the machine, it went to straight to the Stratup Repair, indicating "Attempting repairs... Repairing dis errors. This might take over an hour to complete." It's been like this for nearly 15 hours. When I try to cancel or close the Startup Repair window, I get a message "The current repair operation cannot be cancelled." Should I let it run or force shut the machine? If force shut, how can I resolve this problem? Thanks.

BSOD first started when i installed this SSD and stopped when i've updated the chipset controller driver then started again yesterday when i wanted to change the power settings plan.Minidump file here. Any help with this weird issue appriciated, thanks. Edit: - i've ran Memory diagnostic tool, - Intel SSD diagnostics - and updated the firmware to 3.2.1. Non of these steps worked or shown signs of errors - but still got BSOD when changing power plan settings. After analizing the dump file via osronline.com here a first few lines: CRITICAL_OBJECT_TERMINATION (f4) A process or thread crucial to system operation has unexpectedly exited or been terminated.

• Cannot view dates of emails(no date field), in my CSV file exported from MS Outlook

  - by barlop

  I am using Outlook 2010 - I have my emails showing in there. and exported my emails, into a csv file. (file..options..advanced...export..export to a file.. I have opened that csv file in excel Here is a list of the fields it shows. I see "Date" doesn't appear among them.

Also, (and less importantly, and as a very secondary issue) is there a convenient way to read the csv file? reading an email with a long body, in excel, is not convenient, I need to select all of the body from the cell and copy/paste it into notepad.

• How to embed/hardcode SRT subtitles into mp4 videos with VLC?

  - by Jens Bannmann

  I'm looking for a way to "burn in" or render/rembed/hardcode subtitles (from an SRT file) into an MP4 video with VLC. But no matter what options I use, it never works properly. I get a file that plays video way too fast (audio is normal), or one that plays normally, but actually does not have embedded subtitles. Also, with some options (like the one below) it does not play in QuickTime, only in VLC. So the main question is: how can I make this work in VLC? Secondary questions are: How do I decide which options I should set? Which settings are best if I want to leave the file bitrate etc. the same as much as possible, only embed subtitles? It seems I cannot leave the field empty or Video/Audio unchecked, so I guess I would first need to figure out the original audio and video bitrate. What do the "Scale" and "Channels" options mean? ... none of which are answered within the VLC documentation. For example, this is one set of options I used in the "Advanced Open File…" dialog: Advanced Open File… myFileName.mp4 [ ] Treat as a pipe rather than as a file [x] Load subtitles file: mySubtitleFileName.srt [ ] Play another media synchronously [x] Streaming/Saving Streaming and Transcoding Options [ ] Display the stream locally (o) File [outputFileName.mp4 ] [ ] Dump raw input Encapsulation Method: (MPEG 4 ) Transcoding options [x] Video (mp4v ) Bitrate (kb/s) [256 ] Scale [1 ] [x] Audio (mp3 ) Bitrate (kb/s) [128 ] Channels [1 ]

  I have D-link DSL 2750U wireless router. My PC and notebook are connected to router by Wi-Fi. They can share files or ping each other. I have a network storage unit plugged into router by an ethernet cable. Any of the computers cannot reach that storage unit or ping it. I guess my router isolates LAN network from WLAN network. Is there a way to combine them and get the router treat all devices connected to router in a single network? Thanks.

• Developer’s Life – Every Developer is a Superman

  - by Pinal Dave

  I enjoyed comparing developers to Spiderman so much, that I have decided to continue the trend and encourage some of my favorite people (developers) with another favorite superhero – Superman.  Superman is probably the most famous superhero – and one of the most inspiring. Everyone has their own favorite, but Superman has been the longest enduring of all comic book characters.  Clark Kent has inspired multiple movie series, TV shows, books, cartoons, and costumes.  Superman’s enduring popularity has been attributed to his superhuman strength, integrity, dedication to good, and his humility in keeping his identity a secret. So how are developers like Superman? Well, read on my list of reasons. Secret Identities They have secret identities.  I’m not saying that all developers wear thick glasses and go by an alias like “Clark Kent.”  But developers certainly work in the background, making sure everything runs smoothly, often without recognition.  Like Superman, when they have done their job right, no one knows they were there. Working Alone You don’t have to work alone.  Superman doesn’t have a sidekick like Robin or Bat Girl, but he is a major player in the Justice League.  Developers have amazing skills, and they shouldn’t be afraid to unite those skills to solve some of the world’s major problems (like slow networks). Daily Inspiration Developers are inspiring.  Clark Kent works at The Daily Planet, Metropolis’ newspaper, which is lucky because he can keep some of the publicity Superman inspires under wraps.  Developers might go unnoticed sometimes, but when people hear about some of the tasks they accomplish on a daily basis, it inspires awe. Discover Your Superpowers You have to discover your superpowers.  Clark Kent didn’t just wake up one morning with the full understanding that he could fly, leap tall buildings in a single bound, and was stronger than a speeding locomotive.  He slowly discovered these powers (after a few comic book-worthy misunderstandings!).  Developers are always learning and growing as well.  You probably won’t wake up with super powers, either, but years of practice and continuing education can get you close. Every Day is a New Day The story continues.  The Superman comic books are still being printed, and have been in print since 1938.  There have been two TV series, (one, Smallville, was on TV for ten seasons) and multiple cartoon adaptations.  There have been multiple movies, with many different actors.  A new reboot came out last year, and another is set to premier in 2016.   So, developers, when you are having a bad day or a problem seems unsolvable – remember, the story will continue!  There is always tomorrow. I hope you are all enjoying reading about developers-as-superheroes as much as I am enjoying writing about them.  Please tell me how else developers are like Superheroes in the comments – especially if you know any developers who are faster than a speeding bullet and can leap tall buildings in a single bound.

• Easy Profiling Point Insertion

  - by Geertjan

  One really excellent feature of NetBeans IDE is its Profiler. What's especially cool is that you can analyze code fragments, that is, you can right-click in a Java file and then choose Profiling | Insert Profiling Point. When you do that, you're able to analyze code fragments, i.e., from one statement to another statement, e.g., how long a particular piece of code takes to execute: https://netbeans.org/kb/docs/java/profiler-profilingpoints.html However, right-clicking a Java file and then going all the way down a longish list of menu items, to find "Profiling", and then "Insert Profiling Point" is a lot less easy than right-clicking in the sidebar (known as the glyphgutter) and then setting a profiling point in exactly the same way as a breakpoint: That's much easier and more intuitive and makes it far more likely that I'll use the Profiler at all. Once profiling points have been set then, as always, another menu item is added for managing the profiling point: To achieve this, I added the following to the "layer.xml" file: <folder name="Editors"> <folder name="AnnotationTypes"> <file name="profiler.xml" url="profiler.xml"/> <folder name="ProfilerActions"> <file name="org-netbeans-modules-profiler-ppoints-ui-InsertProfilingPointAction.shadow"> <attr name="originalFile" stringvalue="Actions/Profile/org-netbeans-modules-profiler-ppoints-ui-InsertProfilingPointAction.instance"/> <attr name="position" intvalue="300"/> </file> </folder> </folder> </folder> Notice that a "profiler.xml" file is referred to in the above, in the same location as where the "layer.xml" file is found. Here is the content: <!DOCTYPE type PUBLIC '-//NetBeans//DTD annotation type 1.1//EN' 'http://www.netbeans.org/dtds/annotation-type-1_1.dtd'> <type name='editor-profiler' description_key='HINT_PROFILER' localizing_bundle='org.netbeans.eppi.Bundle' visible='true' type='line' actions='ProfilerActions' severity='ok' browseable='false'/> Only disadvantage is that this registers the profiling point insertion in the glyphgutter for all file types. But that's true for the debugger too, i.e., there's no MIME type specific glyphgutter, instead, it is shared by all MIME types. Little bit confusing that the profiler point insertion can now, in theory, be set for all MIME types, but that's also true for the debugger, even though it doesn't apply to all MIME types. That probably explains why the profiling point insertion can only be done, officially, from the right-click popup menu of Java files, i.e., the developers wanted to avoid confusion and make it available to Java files only. However, I think that, since I'm already aware that I can't set the Java debugger in an HTML file, I'm also aware that the Java profiler can't be set that way as well. If you find this useful too, you can download and install the NBM from here: http://plugins.netbeans.org/plugin/55002

• Many ui panels needs interaction with same object

  - by user877329

  I am developing a tool for simulating systems like the Gray-Scott model (That is systems where spatial distribution depends on time). The actual model is loaded from a DLL or shared object and the simulation is performed by a Simulation object. There are at least two situations when the simulation needs to be destroyed: The user loads a new model The user changes the size of the domain To make sure nothing goes wrong, the current Model, Simulation, and rendering Thread are all managed by an ApplicationState object. But the two cases above are initiated from two different UI objects. Is it then ok to distribute a reference to the ApplicationState object to all panels that need to access at least one method on the ApplicationState object? Another solution would be to use aggregation so that the panel from which the user chooses model knows the simulation parameter panel. Also, the ApplicationState class seems somewhat clumsy, so I would like to have something else

• How far can you get in iOS without learning PhotoShop or another graphic design program? [on hold]

  - by Aerovistae

  I'm in the process of learning iOS, and I'm coming from a web dev background where CSS controls 70-90% of the UI, and Python/C++ desktop dev where there are highly customizable UI toolkits for most things. I'm trying to figure out how people make good-looking apps without graphic design skills. You always hear about some 8 year old or 14 year old who made a successful app. So I assume that even if the required code was relatively basic, the app must have looked good if it was a success. But I find it really unlikely that these kids have advanced PhotoShop skills as well as having learned iOS programming at such a young age. Frankly, the same goes for most independent app developers....as they say, unicorns don't exist. So what's the deal? Can you make a good-looking, market quality app without those skills? What are the limitations?

Connection class - java class just to connect to the database view - jsp to display the results html - used for form Is this how you design a java program based on MVC design pattern? Please provide some suggestions?
