  • I/O Error with PHP5-FPM, ptrace(PEEKDATA) failed

    - by MultiformeIngegno
    I got a lot of these: [NOTICE] child 19214 stopped for tracing [NOTICE] about to trace 19214 [ERROR] ptrace(PEEKDATA) failed: Input/output error (5) [NOTICE] finished trace of 19214 [WARNING] [pool www] child 19208, script 'blahblah.php' executing too slow (30.041419 sec), logging [NOTICE] child 19208 stopped for tracing [NOTICE] about to trace 19208 [ERROR] ptrace(PEEKDATA) failed: Input/output error (5) [NOTICE] finished trace of 19208 [WARNING] [pool www] child 19218, script 'blahblah.php' executing too slow (30.035029 sec), logging And when php reaches max children (at least I presume that's the case) it stops "working"... now I know I can increase max_children (currently set to 9) but there's a way to stop php from "dying"? I'm on a VPS with 1 core and 512 MB of RAM (PHP5-FPM 5.4.4 + APC 3.1.10).

  • How to convert html textfield/area data to server-side txt file? [closed]

    - by olijake
    How can I make a script that will convert the text/data in a html textfield/textarea and send it to the server, which then saves it as a .txt file for storage? NOTE: I am hosting a website(for testing purposes) using Apache 2.2 on a Windows 7 machine. I downloaded PHP version 5.4.7, but have not yet installed on my server yet (not sure if I will need it, but also not sure how to install it). 1st problem: Saving text to server Html page/section with title textfield, text textarea, and submit button. You would enter a title, the text/notes you need in the textfield, then press the submit button to have it store the text in the textarea, as a .txt file on the server called .txt. 2nd problem: Opening text from server Html with list of all txt files OR textfield for entering in title, then submit button to send the title of the requested .txt file to the server, which would then load it up on the page. Here is what I have so far: (let me know if there is something that I should change or if something just isn't correct in the index.html code I have right now.) <!DOCTYPE HTML> <html> <head> <title>Insert Title</title> <meta http-equiv="Content-Type" content="Text/HTML; charset=UTF-8"/> </head> <body> <form method="post" action="save.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <textarea rows="20" cols="100" id="text" name="text"></textarea><br/> <input type="submit" name="submit" value="Submit Text to Server"> </form><br/> <hr style="width: 100%; height: 4px;"><br/> <form method="post" action="open.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <input type="submit" name="submit" value="Submit Txt File Request"> </form><br/> <div>Opened text file displays here or goes on another page</div> </body> </html> I plan on using a server side language/script, but ANYTHING that gets the job done is fine. I already tried looking into using some ASP/jScript/PHP, but have had some trouble implementing it into my server. (ie: getting the modules loaded and telling the server what file types to parse.) I know this may be an extremely easy fix, but then in that case, hopefully you wouldn't mind helping me out a little :). If it turns out that this is MUCH more complicated than I expect, then feel free to let me know that, so I don't waste me time running in circles. I appreciate any help/assistance that you can provide, Thanks, Jake EDIT: Wrong Apache version. In response to the comments/closing of this thread: My question: "How exactly do I install the PHP module on the apache server? and is this even possible? and is this even recommended?" ^ In case I wasn't clear enough already To Clarify: I understand the basics of PHP, I just have trouble with INSTALLING PHP on the apache server. (I have used PHP before, but never successfully on apache (so far...)) For my script I wrote something similar to this already (using fopen() and a few other commands): <?php fopen("notes.txt", "r"); file_put_contents("notes.txt",teststring1); ?> I have used javascript for this task before also (although I prefer using PHP and server-side languages): <script language="javascript"> function WriteToFile(){ var fso = new ActiveXObject("Scripting.FileSystemObject"); var s = fso.CreateTextFile("C:\\NewFile.txt", true); var text=document.getElementById("TextArea1").innerText; s.WriteLine(text); s.WriteLine('***********************'); s.Close(); } </script>

  • How to Buy an SD Card: Speed Classes, Sizes, and Capacities Explained

    - by Chris Hoffman
    Memory cards are used in digital cameras, music players, smartphones, tablets, and even laptops. But not all SD cards are created equal — there are different speed classes, physical sizes, and capacities to consider. Different devices require different types of SD cards. Here are the differences you’ll need to keep in mind when picking out the right SD card for your device. Speed Class In a nutshell, not all SD cards offer the same speeds. This matters for some tasks more than it matters for others. For example, if you’re a professional photographer taking photos in rapid succession on a DSLR camera saving them in high-resolution RAW format, you’ll want a fast SD card so your camera can save them as fast as possible. A fast SD card is also important if you want to record high-resolution video and save it directly to the SD card. If you’re just taking a few photos on a typical consumer camera or you’re just using an SD card to store some media files on your smartphone, the speed isn’t as important. Manufacturers use “speed classes” to measure an SD card’s speed. The SD Association that defines the SD card standard doesn’t actually define the exact speeds associated with these classes, but they do provide guidelines. There are four different speed classes — 10, 8, 4, and 2. 10 is the fastest, while 2 is the slowest. Class 2 is suitable for standard definition video recording, while classes 4 and 6 are suitable for high-definition video recording. Class 10 is suitable for “full HD video recording” and “HD still consecutive recording.” There are also two Ultra High Speed (UHS) speed classes, but they’re more expensive and are designed for professional use. UHS cards are designed for devices that support UHS. Here are the associated logos, in order from slowest to fastest:       You’ll probably be okay with a class 4 or 6 card for typical use in a digital camera, smartphone, or tablet. Class 10 cards are ideal if you’re shooting high-resolution videos or RAW photos. Class 2 cards are a bit on the slow side these days, so you may want to avoid them for all but the cheapest digital cameras. Even a cheap smartphone can record HD video, after all. An SD card’s speed class is identified on the SD card itself. You’ll also see the speed class on the online store listing or on the card’s packaging when purchasing it. For example, in the below photo, the middle SD card is speed class 4, while the two other cards are speed class 6. If you see no speed class symbol, you have a class 0 SD card. These cards were designed and produced before the speed class rating system was introduced. They may be slower than even a class 2 card. Physical Size Different devices use different sizes of SD cards. You’ll find standard-size CD cards, miniSD cards, and microSD cards. Standard SD cards are the largest, although they’re still very small. They measure 32x24x2.1 mm and weigh just two grams. Most consumer digital cameras for sale today still use standard SD cards. They have the standard “cut corner”  design. miniSD cards are smaller than standard SD cards, measuring 21.5x20x1.4 mm and weighing about 0.8 grams. This is the least common size today. miniSD cards were designed to be especially small for mobile phones, but we now have a smaller size. microSD cards are the smallest size of SD card, measuring 15x11x1 mm and weighing just 0.25 grams. These cards are used in most cell phones and smartphones that support SD cards. They’re also used in many other devices, such as tablets. SD cards will only fit into marching slots. You can’t plug a microSD card into a standard SD card slot — it won’t fit. However, you can purchase an adapter that allows you to plug a smaller SD card into a larger SD card’s form and fit it into the appropriate slot. Capacity Like USB flash drives, hard drives, solid-state drives, and other storage media, different SD cards can have different amounts of storage. But the differences between SD card capacities don’t stop there. Standard SDSC (SD) cards are 1 MB to 2 GB in size, or perhaps 4 GB in size — although 4 GB is non-standard. The SDHC standard was created later, and allows cards 2 GB to 32 GB in size. SDXC is a more recent standard that allows cards 32 GB to 2 TB in size. You’ll need a device that supports SDHC or SDXC cards to use them. At this point, the vast majority of devices should support SDHC. In fact, the SD cards you have are probably SDHC cards. SDXC is newer and less common. When buying an SD card, you’ll need to buy the right speed class, size, and capacity for your needs. Be sure to check what your device supports and consider what speed and capacity you’ll actually need. Image Credit: Ryosuke SEKIDO on Flickr, Clive Darra on Flickr, Steven Depolo on Flickr

  • IIS7 URL Rewrite - Rewrite CSS files

    - by user1231958
    I'm trying to rewrite certain CSS files with some rules, so it replaces every single instance of links in the CSS (as in background: url("/myuri.jpg")) with a prefix (as in background: url("/zeus/myuri.jpg")) These are the rules. <rule name="ReverseProxyOutboundRule2" preCondition="IsCSS" enabled="true" stopProcessing="false"> <match filterByTags="None" pattern="url\(&quot;(.*)&quot;\)" /> <action type="Rewrite" value="url(&quot;/zeus{R:1}&quot;)" /> <conditions> <add input="{URL}" pattern="/zeus" /> </conditions> </rule> <preCondition name="IsCSS"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/css" /> </preCondition> However, only one url is being replaced this way and somehow the rest is being ignored. Thank you beforehand.

  • Creating Custom HTML Helpers in ASP.NET MVC

    - by Shravan
    ASP.NET MVC provides many built-in HTML Helpers.  With help of HTML Helpers we can reduce the amount of typing of HTML tags for creating a HTML page. For example we use Html.TextBox() helper method it generates html input textbox. Write the following code snippet in MVC View: <%=Html.TextBox("txtName",20)%> It generates the following html in output page: <input id="txtName" name="txtName" type="text" value="20" /> List of built-in HTML Helpers provided by ASP.NET MVC. ActionLink() - Links to an action method. BeginForm() - Marks the start of a form and links to the action method that renders the form. CheckBox() - Renders a check box. DropDownList() - Renders a drop-down list. Hidden() - Embeds information in the form that is not rendered for the user to see. ListBox() - Renders a list box. Password() - Renders a text box for entering a password. RadioButton() - Renders a radio button.TextArea() - Renders a text area (multi-line text box). TextBox () - Renders a text box. How to develop our own Custom HTML Helpers? For developing custom HTML helpers the simplest way is to write an extension method for the HtmlHelper class. See the below code, it builds a custom Image HTML Helper for generating image tag.

  • Wacom Bamboo CTH460L issues

    - by Robert Smith
    I recently bought a Wacom Bamboo Pen & Touch CTH460L. I installed doctormo's PPA, however, the pen functionality didn't work and the touch was very glitchy (when I touched it, it immediately double clicked and began to drag elements in the screen). I tried to configure it using the wacom-utility package in the Synaptic Package Manager (version 1.21-1) but that didn't work either. Then I followed this post (#621, written by aaaalex), and after some problems trying to restart Ubuntu (graphics related problems), the pen works fine (it could be better, though) but the touch functionality doesn't work anymore. Currently I have installed xserver-xorg-input-wacom (1:0.10.11-0ubuntu7), wacom-dkms (0.8.10.2-1ubuntu1) and wacom-utility. The Wacom Utility only displays an "options" field under "Wacom BambooPT 2FG 4X5" but no other option to configure it. What is the correct way to get this tablet working on Ubuntu 10.04?. By the way, currently I can't start Ubuntu properly when the tablet is connected (in that case, Ubuntu start in low graphics mode). I need to connect it later. UPDATE: I uninstalled xserver -xorg-input-wacom, and wacom-utility because one of them prevented Ubuntu to start normally. I only re-installed wacom-dkms 0.8.10.2-1ubuntu1. The pen is working but no touch functionality. The side buttons don't work either. Thanks in advance.

  • Rapid prototyping and refactoring

    - by Puckl
    Sometimes when I start a small project (like an android app), I don´t know which approach will work out at the end, and I just go for one approach and give it a try. But if I never used this approach before (for a sort of application I´ve never programmed before) it is like stepping into unknown terrain. I don´t know which libraries to use (maybe I have to try out several libraries) and there are so many unkonwns (like: how to get raw audio data in android) So then my development process goes like this: Write a piece of code to see if the approach has a chance. (The more uncertain the approach is, the uglier the code gets) If it works, refactor a lot until it is beautiful I think it could be a waste of time if I planned my software design in detail at this point, it would be like planning a trip without a map. Is this part of aglie development? How do you deal with unknown terrain in software development?

  • First time application where to start?

    - by Nazariy
    After many years of searches and copy pasting, I'm still looking for simple solution that can transliterate text input on the fly from one key set to another. There are quite few online services that provide this feature but it still quite annoying to go online all the time. Unfortunately there is not that many applications left which are capable of doing so, and none of them supported by this day. I decided to make my own and at same time to learn something new for my self. The idea is quite simple: application should sit in system tray and wait until input language get changed, for example to Russian. If Russian language is activated, application should start to listen for user key strokes combination and replace them based on custom dictionary for example R = ?, SH = ? etc. I should be able to bind application to any installed language (Russian, Ukrainian, Bulgarian, Belarusian etc.) and customise dictionary for any of them. So my question is: Which language should I chose for this task C++, C# or might be something hardcore like Assembler, as application should work natively with Windows XP/Vista/7 or possibly Mac. (cross platform support is good but my main target is Windows) Due to nature of application behaviour how can I tell anti-virus software that it is not a "Key Logger" and basically not a virus? Where should I start and what should I be aware of? P.S. My current programming knowledge is quite basic, PHP and JavaScript with Object Oriented approach.

  • Question about casting a class in Java with generics

    - by Florian F
    In Java 6 Class<? extends ArrayList<?>> a = ArrayList.class; gives and error, but Class<? extends ArrayList<?>> b = (Class<? extends ArrayList<?>>)ArrayList.class; gives a warning. Why is (a) an error? What is it, that Java needs to do in the assignment, if not the cast shown in (b)? And why isn't ArrayList compatible with ArrayList? I know one is "raw" and the other is "generic", but what is it you can do with an ArrayList and not with an ArrayList, or the other way around?

  • Is gstreamer the best encoder for vorbis or is there a better encoding engine I should use?

    - by sayth
    I have sound juicer installed and I want to rip to vorbis.ogg. Is gstreamer the best encoder for vorbis or is there a better encoding engine I should use. The default gstreamer profile is audio/x-raw-float,rate=44100,channels=2 ! vorbisenc name=enc quality=0.5 ! oggmux I am going to raise the quality to 0.7 but thats all nothing if gstreamer isn't the best encoder. Any suggestions for high quality ripping? Edit: a good answer to this will also be the top search result in google for "best vorbis encoding engine". Double Edit: It appears oggenc itself is the best encoder which rules out using sound juicer to rip cd's as it uses gstreamer. I have installed oggenc and am testing the command ripper abcde. Found a good configuration for it here oggenc config for abcde

  • Best approach for a database of long strings

    - by gsingh2011
    I need to store questions and answers in a database. The questions will be one to two sentences, but the answers will be long, at least a paragraph, likely more. The only way I know about to do this right now is an SQL database. However, I don't feel like this is a good solution because as far as I've seen, these databases aren't used for data of this type or size. Is this the correct way to go or is there a better way to store this data? Is there a better way than storing raw strings?

  • How to test if SYN and FIN are both dropped at the same time in hping3?

    - by snow
    One of the rules to prevent unexpected attack is to prevent SYN & FIN being used together. SYN and FIN are both set $IPT -A INPUT -p tcp --tcp-flags SYN,FIN SYN,FIN -j DROP How do I use hping to test if this iptable rule works? hping3 192.168.7.0 --keep -S -F??? Is this complete? When just type iptables -L, it shows: Chain INPUT (policy DROP) target prot opt source destination ACCEPT all -- anywhere anywhere DROP tcp -- anywhere anywhere tcp flags:FIN,SYN/FIN,SYN WHY do I need to put the "SYN,FIN" twice before drop? Is it because one for source and one for destination?

  • How to escape this in the bash script?

    - by allenskd
    I'm trying to complete a batch of 3 videos to leave it there till morning processing but it seems there are special characters in it... I try it "raw" in the terminal and it works but in bash script it stops working Example: args1="-r 29.97 -t 00:13:30 -vsync 0 -vpre libx264-medium -i" args12="-r 29.97 -ss 00:40:30 -vsync 0 -vpre libx264-medium -i" args2="[in] scale=580:380 [T1],[T1] pad=720:530:0:50 (other arguments with lots of [ and ]" In the output it says Unable to find a suitable output format for 'scale=580:380' not sure why... like I said, the command runs fine in the command-line, just not in the script /usr/local/bin/ffmpeg "$args1" "${file}" -vf "$args2" "$args3" "${args[0]}_${startingfrom}_0001_02.mp4"

  • Is it possible to run two separate instances (copies, versions) of Audacity?

    - by cipricus
    What I want is two separate instances of Audacity running in parallel as to separate programs with different settings. I want one to use WASAPI as audio host and speakers as input device (the 2.0.5 portable has the WASAPI option), and the other to use the MME as audio host, and microphone as input device. When opening a new (second) window of the same installation/copy of Audacity, by executing twice the .exe file, it is the same as giving the command 'new' under 'File', what happens is not a second instance, but just a separate project/file and window. When settings are changed in one, they change exactly in the other. When trying to start a second copy of Audacity, or even a second different version, when one is already running, it will also open just a second project/file of the application that is already running, as before.

  • Looking for Light Time Management Software Suggestions (for Mac)

    - by tmo256
    I'm looking for a simple project management app that performs task scheduling, along the line of Merlin or MS Project, but no where near as robustly. I don't need to deal with other (human) resources, but I work on anything from 3 to 6 different projects at a time. What I'd like is to be able to input deadlines and tasks, and have a schedule suggested to complete them. I do technical work, but I don't think I need anything specifically for software development, especially considering I do plenty of other kinds of things, like graphic design and social media PR. I'd really like this to be dead simple, as simple as possible. Suggestions? OmniPlan, something web-based? Definitely cannot afford anything too extravagant, really looking for something under $200. Thanks for your input!

  • Unity custom shaders and z-fighting

    - by Heisenbug
    I've just readed a chapter of Unity iOS Essential by Robert Wiebe. It shows a solution for handling z-figthing problem occuring while rendering a street on a plane with the same y offset. Basically it modified Normal-Diffuse shader provided by Unity, specifing the (texture?) offset in -1, -1. Here's basically what the shader looks like: Shader "Custom/ModifiedNormalDiffuse" { Properties { _Color ("Main Color", Color) = (1,1,1,1) _MainTex ("Base (RGB)", 2D) = "white" {} } SubShader { Offset -1,-1 //THIS IS THE ADDED LINE Tags { "RenderType"="Opaque" } LOD 200 CGPROGRAM #pragma surface surf Lambert sampler2D _MainTex; fixed4 _Color; struct Input { float2 uv_MainTex; }; void surf (Input IN, inout SurfaceOutput o) { half4 c = tex2D (_MainTex, IN.uv_MainTex) *_Color; o.Albedo = c.rgb; o.Alpha = c.a; } ENDCG } FallBack "Diffuse" } Ok. That's simple and it works. The author says about it: ...we could use a copy of the shader that draw the road at an Offset of -1, -1 so that whenever the two textures are drawn, the road is always drawn last. I don't know CG nor GLSL, but I've a little bit of experience with HLSL. Anyway I can't figure out what exactly is going on. Could anyone explain me what exactly Offset directly does, and how is solves z-fighting problems?

  • How to make Xbox joypad work with Bastion?

    - by Alistair Buxton
    I have an XBox joypad: Bus 005 Device 004: ID 045e:0289 Microsoft Corp. Xbox Controller S When I start Bastion from the terminal the following is output: Number of joysticks: 1 Number of buttons for joystick: 0 - 10 Number of axes for joystick: 0 - 6 Number of PovHats for joystick: 0 - 1 When I load up the game it displays a message "press any key" and at this point, if I press a button on the joypad it advances to the main menu. However, the up/down/left/right controls do not work and the button will not operate the menu. When I enter the control configuration, the joypad section is disabled and displays a message "joypad not detected." If I enter the control customization and try to reconfigure one of the controls, noises can be heard when pressing joypad buttons, but the input is otherwise ignored. Further information which may or may not be relevant: My controller is an original Xbox controller, not a 360 controller. XNA games on Windows apparently only work with Xbox360 controllers because they use xinput rather than direct input, see eg here. My controller works (almost) properly with MonoGame trunk samples, but Bastion uses a modified MonoGame and crashes when run against trunk, so I can't add debugging to see where the problem is. Bug can also be reproduced with a Xbox 360 wired controller.

  • Will my laptop be ok with this different laptop charger?

    - by tidbits
    So the original laptop charger broke and I switched to a charger from a laptop that I no longer use. The specifications from each are: Original Input:AC 100-240V 1.5A 50-60Hz Output: DC 19V 3.42A Other Charger Input: AC 100-240V 1.5A 50-60Hz Output: 20V 3.25A Yes, the polarity is the same. Also, the wattage has a difference of .02 from what I understand. Is wattage ever important, and more specifically, a wattage difference of that size. Feel free to ask me any other questions about the chargers and I'll answer them to the best of my ability.

  • Error mounting: mount exited with exit code 13

    - by Mike Williamson
    I keep a windows partition on my laptop for the occaisional bit of Photoshop work. A while ago I noticed that Windows had disappeared from my grub boot menu and when I try to mount the windows partion, my system hangs for a bit and then I get this: Unable to mount 105 GB Filesystem Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to calculate free MFT records: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. It seems that chkdsk is a windows command but since I can't boot into windows (since its the windows partition that is the problem) I'm not sure what to do. Here is the output of fdisk to give you the lay of the land: Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x98000000 Device Boot Start End Blocks Id System /dev/sda1 1 10199 81923436 83 Linux /dev/sda2 * 10200 22947 102398310 7 HPFS/NTFS /dev/sda3 22948 29164 49938052+ 83 Linux /dev/sda4 29165 30401 9936202+ 5 Extended /dev/sda5 29165 30401 9936171 82 Linux swap / Solaris Any guidance would be appreciated!
