• best way to quickly share multiple photos without permanently hosting them

  - by dsollen

  I find that I'm often asked to share lots of photos with someone, enough that uploading each one individually to them gets tedious when I would like to drag and drop the whole bunch. I could put them on photobucket, but some of them are semi-private; private enough that I don't want them to be easily found on image hosting sites. Are there any convenient ways of sharing these photos quickly but still being able to remove them from the inter-webs afterwards (without too much hassle)? I have found Yahoo Messenger complete version has great photo sharing options; but not everyone has it and I can't expect people to download it just to see some photos.

• Removing write permission on home and public_html on Centos/Cpanel

  - by user5858

  I'm running sites on two Cpanel accounts on my VPS on WHM. I'm using DSO php handler and Apache server on my Web server. After recent intrusion attacks I've chowned to root with permission 555 on $HOME and public_html folder. I'm on VPS with Cpanel on Centos. I'm running CMS based software like Joomla Drupal etc. Will this cause any problem to my VPS installation or server side processes? Drupal, Joomla, MyBB etc will not be affected by this. Some files will not be created like error_log. At least hackers will not be able to place any malicious code within home folder or the public_html folder.

• inetmgr missing after vista iis7 install

  - by GHarping

  I have installed IIS7 on Vista with all options from Programs and Features->Turn on/off windows features. I have searched for inetmgr accross the whole system with no luck. It is also not present in C:\Windows\System32\inetsrv. The IIS Admin Service is shown as running in the list of all services. Might anyone know what the problem is? My initial problem before this was that after installing IIS and trying to view any arbitrary page via localhost/*filename*, i recieved the error HTTP Error 404.4 - Not Found The resource you are looking for does not have a handler associated with it.

• Why not install Msvcr71.dll into system32?

  - by hillu

  While looking for an authoritative source for the missing Msvcr71.dll that is needed by a few old applications, I stumbled across the MSDN article Redistribution of the shared C runtime component in Visual C++. The advice given to developers is to drop the DLL into the application's directory instead of system32 since DLLs in this directory are considered before the system paths. What can/will go wrong if I (as an administrator, not a developer) decide to take the lazy path and install Msvcr71.dll (and Msvcp71.dll while I'm at it) into the system32 directory (of 32 bit Windows XP or Windows 7 systems) instead of putting a copy in each application's directory? Is there another good solution to provide the applications with the needed DLLs that doesn't involve copying stuff to the application directories?

• How do I open a file with a program via a shortcut from the cmd prompt

  - by PassByReference0

  Here's my predicament: When I add a program's location to my PATH, I can do the following in cmd prompt to open a file in my current directory: notepad++ open_me.txt And this opens open_me.txt in notepad++. However, I don't want to have to add every single program I want to run to my path. What I want is to add a folder called C:\Users\Me\Documents\Programs to my path and just drop shortcuts to various programs into that folder and have them function the same as adding them to my path. So I dropped a link to notepad++.exe named "np" in my folder, and what I got was this: I have to run it with start np (instead of just np) But more importantly, if I try start np open_me.txt, it opens notepad++.exe but looks for open_me.txt in notepad++'s directory. How can I do this properly? (Also, I'd like to be opening notepad++.exe with the shortened name of np)

• Toggle "ask for password after screensaver/sleep" or the delay in 10.7 using terminal

  - by desbo

  There's an option in the preference panel to change the time the mac is able to be in sleep/screensaver before requiring a password to be unlocked again. I'm using OS X Lion 10.7. Is there any way to change this setting using the terminal or an applescript? I tried to change the plist file using: defaults write com.apple.screensaver askForPasswordDelay -int 60 also tried defaults write com.apple.screensaver askForPasswordDelay -float 60 also completely disabling the password didnt work either defaults write com.apple.screensaver askForPassword -int 0 The plist file was changed, but it had no effects at all. It's the same plist file that gets changed when manually switching the setting in the preferences. Would be awesome if anyone got an idea how to fix my problem. EDIT: also tried to: 1) add -currentHost flag 2) drop the -int / -float

• recommended way to collect email notifications from crond in Arch Linux

  - by nponeccop

  Arch Linux doesn't have sendmail installed by default. So I get the following messages in my syslog: Sep 15 13:16:01 zorro crond[18497]: mailing cron output for user collectors sh cronjob.sh Sep 15 13:16:01 zorro crond[18497]: unable to exec /usr/sbin/sendmail: cron output for user collectors sh cronjob.sh to /dev/null What is the recommended way to fix this default behaviour so actual messages are sent? heirloom-mailx is installed and capable of sending email messages using SMTP. Is it possible for crond to use mailx to send notifications? Is there any drop-in replacement for sendmail that sends using mailx? Sendmail is not even in the repositories.

• Is there analog of aticonfig --set-powerstate for open source radeon driver?

  - by vava

  I'm running Ubuntu 9.04 on relatively old laptop with ATI Mobility x600 inside. On the last version of Ubuntu, when I was able to run proprietary fglrx driver, I was able to slow down graphic card by aticonfig --set-powerstate 1 and save some battery charge. Now I forced to run open source driver as ATI decided to drop support for old cards. But I can't find a way to control power states now except relying on DynamicClocks option in xorg.conf. But I really know better when and what powerstate I want, so is there a tool that let me change power state manually or at least let me somehow change the behavior of automatic power state selection?

• How to get age field in Google Docs form:

  - by Juhele

  we need to create a form asking the clients for their age. Is there any way to create a field where you can only fill in numbers - maybe only 4 numbers like 1976 or 2011. Second alternative could be date. It would be perfect if I could limit the number - something like "not lower than 1800 and not higher than 2012" to prevent invalid numbers. I can create question with drop down list, but creating a list of all possible years would be stupid and incomfortable to choose from. thanks much

• Using nginx and/or varnish to cache server-generated 301 redirects

  - by rlotun

  I'm implementing a sort of url-shortener service. What happens is that I have some backend app server that takes in a request, does some computation and returns a 301 redirected url back upstream to an nginx frontend: request ---> nginx ----> app_server What I want to be able to do is cache this returned 301 url for the same request (a specific url with a "short code"). Does nginx do this caching automatically? Or should I drop in something like varnish in between nginx and the app_server? I can easily cache this in memcache, but that would require hitting the app_server, which I'm sure can be dispensed with after the first request. Thanks.

• Issue with emails with attached emails.

  - by Jake

  There is this problem with our email in my organisation that happens to some people. When a remote sender sends an email that has an attached email, the reciever gets the email but the attached email is blank. The recieving mail server is MDaemon Pro. I also notice that the email header could be corrupted. I checked the MDaemon KB and find nothing regarding this issue. but I also highly doubt that this is an MS Outlook 2007 issue. Anyone have any ideas? Putting this issue aside, I feel that we really should not attach emails to emails. There is a reason for the "Forward" button. I can't understand why is it so difficult for them to just forward that email instead of drag and drop one into the other using outlook. Furthermore, if the attached email also has its own attachments, the resulting nesting will be quite unbearable. Don't you think so?

• Can't serve files without extension because they "appear to be script" on IIS7.5

  - by madd0

  I created a certain number of static JSON files with no extension in a subfolder of my site. I want to use them for tests. The problem is that IIS is refusing to serve them because : HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. The folder is a subfolder of an ASP.NET application and I can't create an application just for it, neither can I change the parent application's application pool. Actually, I don't have access to the IIS configuration other than through the web.config file in the folder in question. I assume there must be a way to get a web server to serve static files, right?

• Panic Transmit file upload

  - by 1ndivisible

  I've ditched Coda and bought Transmit. I'm a little confused by the file uploading. I have exactly the same folder structure remotely and locally, but if I right-click a file and choose Upload "SomeFileName.html" The file is always uploaded into the root of the remote site, even if the file is in a folder. If I choose to upload a file at assets/images/some_image.png I would expect it to be uploaded to the same folder on the remote server, not the root. Coda dealt with this perfectly and also told me what files had been modified and needed uploading. Transmit doesn't seem to do either of these things. So my questions are: How can I upload a file to the same path on the remote server without having to drag and drop Is there any way to have Transmit mark edited files or upload only edited files. [There is no tag for Transmit so if someone with more rep could make and add one that would be grand]

• Android passing an arraylist back to parent activity

  - by Nicklas O

  Hi there. I've been searching for a simple example of this with no luck. In my android application I have two activities: 1. The main activity which is launched at startup 2. A second activity which is launched by pressing a button on the main activty. When the second activity is finished (by pressing a button) I want it to send back an ArrayList of type MyObject to the main activity and close itself, which the main activity can then do whatever with it. How would I go about achieving this? I have been trying a few things but it is crashing my application when I start the second activity. When the user presses button to launch second activity: Intent i = new Intent(MainActivity.this, secondactivity.class); startActivityForResult(i, 1); The array which is bundled back after pressing a button on the second activity: Intent intent= getIntent(); Bundle b = new Bundle(); b.putParcelableArrayList("myarraylist", mylist); intent.putExtras(b); setResult(RESULT_OK, intent); finish(); And finally a listener on the main activity (although I'm not sure of 100% when this code launches...) protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(resultCode==RESULT_OK && requestCode==1){ Bundle extras = data.getExtras(); final ArrayList<MyObject> mylist = extras.getParcelableArrayList("myarraylist"); Toast.makeText(MainActivity.this, mylist.get(0).getName(), Toast.LENGTH_SHORT).show(); } } Any ideas where I am going wrong? The onActivityResult() seems to be crashing my application. EDIT: This is my class MyObject, its called plan and has a name and an id import android.os.Parcel; import android.os.Parcelable; public class Plan implements Parcelable{ private String name; private String id; public Plan(){ } public Plan(String name, String id){ this.name = name; this.id = id; } public String getName(){ return name; } public void setName(String name){ this.name = name; } public String getId(){ return id; } public void setId(String id){ this.id = id; } public String toString(){ return "Plan ID: " + id + " Plan Name: " + name; } @Override public int describeContents() { // TODO Auto-generated method stub return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(id); dest.writeString(name); } public static final Parcelable.Creator<Plan> CREATOR = new Parcelable.Creator<Plan>() { public Plan createFromParcel(Parcel in) { return new Plan(); } @Override public Plan[] newArray(int size) { // TODO Auto-generated method stub return new Plan[size]; } }; } This is my logcat E/AndroidRuntime( 293): java.lang.RuntimeException: Unable to instantiate activ ity ComponentInfo{com.daniel.android.groupproject/com.me.android.projec t.secondactivity}: java.lang.NullPointerException E/AndroidRuntime( 293): at android.app.ActivityThread.performLaunchActiv ity(ActivityThread.java:2417) E/AndroidRuntime( 293): at android.app.ActivityThread.handleLaunchActivi ty(ActivityThread.java:2512) E/AndroidRuntime( 293): at android.app.ActivityThread.access$2200(Activi tyThread.java:119) E/AndroidRuntime( 293): at android.app.ActivityThread$H.handleMessage(Ac tivityThread.java:1863) E/AndroidRuntime( 293): at android.os.Handler.dispatchMessage(Handler.ja va:99) E/AndroidRuntime( 293): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 293): at android.app.ActivityThread.main(ActivityThrea d.java:4363) E/AndroidRuntime( 293): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 293): at java.lang.reflect.Method.invoke(Method.java:5 21) E/AndroidRuntime( 293): at com.android.internal.os.ZygoteInit$MethodAndA rgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 293): at com.android.internal.os.ZygoteInit.main(Zygot eInit.java:618) E/AndroidRuntime( 293): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 293): Caused by: java.lang.NullPointerException E/AndroidRuntime( 293): at com.daniel.android.groupproject.login.<init>( login.java:51) E/AndroidRuntime( 293): at java.lang.Class.newInstanceImpl(Native Method ) E/AndroidRuntime( 293): at java.lang.Class.newInstance(Class.java:1479) E/AndroidRuntime( 293): at android.app.Instrumentation.newActivity(Instr umentation.java:1021) E/AndroidRuntime( 293): at android.app.ActivityThread.performLaunchActiv ity(ActivityThread.java:2409) E/AndroidRuntime( 293): ... 11 more

• fail2ban on server with LXC Containers

  - by RoboTamer

  The issue is modprobe and iptables don't work inside an LXC Container. LXC is the userspace control package for Linux Containers, a lightweight virtual system mechanism sometimes described as “chroot on steroids”. iptables error inside the container is: # iptables -I INPUT -s 122.129.126.194 -j DROP > iptables v1.4.8: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. I am guessing that it can't work because the LXC containers share one kernel, the main server kernel. How do I do fail2ban in this case. modprobe and iptables work in the main server so I could install it there and link to the logfiles somehow, my guess? Any suggestions?

• PostgreSQL disaster recovery options

  - by Alex

  My customer has quite a large (the total "data" folder size is 200G) PostgreSQL database and we are working on a disaster recovery plan. We have identified three different types of disasters so far: hardware outage, too much load and unintentional data loss due to erroneously executed bad migration (like DELETE or ALTER TABLE DROP COLUMN). First two types seem to be easy to mitigate but we can't elaborate a good mitigation plan for the third type. I proposed to use ZFS and frequent (hourly) snapshots but "ZFS" means "OpenIndiana" these days and our Ops engineers do not have much expertise in it, so using OpenIndiana imposes another risk. Colleagues try to convince me that restoring from PostgreSQL PITR backup can be as fast as restoring from a ZFS snapshot but I highly doubt that replaying, say, 50G of archived WALs can be considered "fast". What other options are we missing? Is ZFS an only viable alternative? Can we get a fast Pg DB restore time in the Linux environment?

• Retrieve malicious IP addresses from Apache logs and block them with iptables

  - by Gabriel Talavera

  Im trying to keep away some attackers that try to exploit XSS vulnerabilities from my website, I have found that most of the malicious attempts start with a classic "alert(document.cookie);\" test. The site is not vulnerable to XSS but I want to block the offending IP addresses before they found a real vulnerability, also, to keep the logs clean. My first thought is to have a script constantly checking in the Apache logs all IP addresses that start with that probe and send those addresses to an iptables drop rule. With something like this: cat /var/log/httpd/-access_log | grep "alert(document.cookie);" | awk '{print $1}' | uniq Why would be an effective way to send the output of that command to iptables? Thanks in advance for any input!

• Do you have suggestions for these assembly mnemonics?

  - by Noctis Skytower

  Greetings! Last semester in college, my teacher in the Computer Languages class taught us the esoteric language named Whitespace. In the interest of learning the language better with a very busy schedule (midterms), I wrote an interpreter and assembler in Python. An assembly language was designed to facilitate writing programs easily, and a sample program was written with the given assembly mnemonics. Now that it is summer, a new project has begun with the objective being to rewrite the interpreter and assembler for Whitespace 0.3, with further developments coming afterwards. Since there is so much extra time than before to work on its design, you are presented here with an outline that provides a revised set of mnemonics for the assembly language. This post is marked as a wiki for their discussion. Have you ever had any experience with assembly languages in the past? Were there some instructions that you thought should have been renamed to something different? Did you find yourself thinking outside the box and with a different paradigm than in which the mnemonics were named? If you can answer yes to any of those questions, you are most welcome here. Subjective answers are appreciated! Stack Manipulation (IMP: [Space]) Stack manipulation is one of the more common operations, hence the shortness of the IMP [Space]. There are four stack instructions. hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item Arithmetic (IMP: [Tab][Space]) Arithmetic commands operate on the top two items on the stack, and replace them with the result of the operation. The first item pushed is considered to be left of the operator. add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo Heap Access (IMP: [Tab][Tab]) Heap access commands look at the stack to find the address of items to be stored or retrieved. To store an item, push the address then the value and run the store command. To retrieve an item, push the address and run the retrieve command, which will place the value stored in the location at the top of the stack. save Store load Retrieve Flow Control (IMP: [LF]) Flow control operations are also common. Subroutines are marked by labels, as well as the targets of conditional and unconditional jumps, by which loops can be implemented. Programs must be ended by means of [LF][LF][LF] so that the interpreter can exit cleanly. L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller halt End the program I/O (IMP: [Tab][LF]) Finally, we need to be able to interact with the user. There are IO instructions for reading and writing numbers and individual characters. With these, string manipulation routines can be written. The read instructions take the heap address in which to store the result from the top of the stack. print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack Question: How would you redesign, rewrite, or rename the previous mnemonics and for what reasons?

• Why does diskpart set the volume attributes on all volumes?

  - by Nick

  I was trying to migrate a Win7 OS from a HDD to a SSD. I've created 2 partition with 1024KB offset, with diskpart: 100MB System Reserved and a 60GB for C:. I've cloned their contents using Easeus Disk Copy. I've loaded the Windows 7 Boot DVD, and wanted to use diskpart to drop the letter for the System Reserved partition and make it hidden. select volume 0 detail volume attribute volume set nodefaultdriveletter attribute volume set hidden These 2 attribute set commands actioned on both volumes (0 and 1, MSR and C:) instead of the selected one, and viceversa. I've tried to clear these attributes from volume 1, but it cleared them also from volume 0. Why does DiskPart have this behaviour?

• REST-based file server

  - by Chris Wenham

  I need to be able to PUT files and GET them later using nothing but HTTP, so I went searching for something that might match the terms "REST file server" or "HTTP file server" or "REST drop-box", etc. Unfortunately, these terms bring up the wrong kind of results on Google. What I want is the equivalent of an SMB fileshare over HTTP. Some ideal features: Can PUT a file of any type at http://servername/service/any/path/I/want/document.pdf Anyone with access can GET that file at the URL I PUT it at Supports AV scanning on any new file that has been PUT Supports DELETE of existing resources (files) Our shop runs Windows, but I'd be interested to know about Unix software that can do this kind of thing, too. It's to be used in an IT department for private users only. It won't be on a public-facing IP address. Does anything like this exist?

• How can I register a custom protocol with xdg?

  - by julien

  I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.
