• Is there any SMS/MMS server for LAN environment

  - by Chau Chee Yang

  I am looking for a solution to send SMS/MMS message to mobile device from desktop or browser in LAN environment. As such, it is most probably using TCP/IP protocol to transmit request/response. The server may attach to a GSM device with SIM card attached. An server application would then start accept the request from any LAN client and convey the SMS/MMS to one or more recipients. The server may log all requests for further traffic analysis in later stage. Is there any solution that able to perform what I describe here. Please advice.

• Hylafax: Encounter "No font metric information" when try to send a fax

  - by Chau Chee Yang

  I am using Hylafax 6.0.5 on Fedora 13 x86_64. As there are no rpm package available for Fedora 13, I use the source tar ball to install hylafax myself. Everything seems fine during compile and install. I try to send a fax with sendfax and encounter error: # sendfax -n -d <fax-number> /etc/passwd /usr/local/sbin/textfmt: No font metric information found for "Courier-Bold". Usage: /usr/local/sbin/textfmt [-1] [-2] [-B] [-c] [-D] [-f fontname] [-F fontdir(s)] [-m N] [-o #] [-p #] [-r] [-U] [-Ml=#,r=#,t=#,b=#] [-V #] files... >out.ps Default options: -f Courier -1 -p 11bp -o 0 Error converting document; command was "/usr/local/sbin/textfmt -B -f Courier-Bold -Ml=0.4in -p 11 -s default >'/tmp//sndfaxp5GdJ9' <'/etc/passwd'" It seems like there is problem with font problem. I have ghostscript-fonts installed too. I can't find hyla.conf in path /etc/hylafax. There is no /etc/hylafax path in my file system. All configuration files seems located in /var/spool/hylafax/etc. Please advice. Thank you.

• Google Reader offline sync (Gears) not syncing, stuck at 0%

  - by Yang

  I'm using Google Chrome, and for some reason starting over the weekend or Friday, I haven't been able to get Google Reader to sync for offline reading. When I hit the sync button, it just starts spinning and says: "Status: Downloading 2000 items...0% completed. Please wait..." There's no CPU, network, or disk activity on my machine, and it remains in this state indefinitely. I tried going to Chrome Settings, uninstalling Reader, navigating to Reader, and reinstalling Reader as a Gears app, to no avail. Any hints? Thanks in advance.

• Operating altitude for a MacBook Pro?

  - by Jeff Meatball Yang

  I saw on the Apple website that the MacBook pro has a maximum operating altitude. Maximum operating altitude: 10,000 feet Does this mean that I should not use it on a plane? Or is this just a slick way for Apple to say, "It's not our fault if you use it on a plane and it breaks."

• How to prevent mod_proxy from rewriting redirects into absolute URLs?

  - by Yang

  I have: nginx (port 80) reverse-proxying to apache2 (port 88) reverse-proxying to a web app (port 5001). However, when the web app responds with a redirect like Location: /foo, apache2 rewrites this into Location: http://host.com:88/sub/foo, even though port 88 is publicly inaccessible. I'd like it to just redirect to the relative URL Location: /sub/foo. Any ideas? My apache config (using mod_proxy_http, mod_proxy_html, mod_substitute): <Location /notes/> Allow from all ProxyPass http://127.0.0.1:5001/ SetOutputFilter proxy-html ProxyPassReverse / ProxyHTMLURLMap / /notes/ RequestHeader unset Accept-Encoding AddOutputFilterByType SUBSTITUTE application/atom+xml Substitute "s|127.0.0.1:5001|host.com/notes|" </Location>

• How to configure sendmail to relay local user mail to public host?

  - by Chau Chee Yang

  I am using Linux/Fedora's sendmail as my mail server. The server do not has a public domain name. It connect to Internet via dial-up. There are few users in the server. I have successfully configure my sendmail to relay mail to public host (via smart_host): # mail <user>@gmail.com [email protected] receive mail from this private host. However, if I send a mail to local user (without domain name): # mail <user> All mails are deliver to my server's mail spooler (/var/spool/mail). I wish all mails send to local user may relay to a public domain that I have registered, is that possible to do so with sendmail? mail user1 will send mail to [email protected] mail user2 will send mail to [email protected]

• Recover open but deleted file on Linux using ln instead of cp

  - by Yang

  Say I have a file that's downloading (from a source that's hard to re-download from), but accidentally deleted from the filesystem namespace (/tmp/blah), and I'd like to recover this file. Normally I could just cp /proc/$PID/fd/$FD /tmp/blah, but in this case that would only get me a partial snapshot, since the file is still downloading. Furthermore, once the download completes, the downloading process (e.g. Chrome) will close the FD. Any way to recover by inode/create a hard link? Any other solutions? If it makes any difference, I'm mainly concerned with ext4. Thanks in advance.

• VPN access configuration with ForeFront TMG

  - by Yang

  I am trying to configure VPN Client access with ForeFront TMG. When I try to add domain groups to allow access to them, under Group column I can only see the SID of the domain group. And the Domain column ends up empty. ForeFront TMG is joined to the domain. Can you think of a reason?

• How to set up a PRIVATE vimwiki on Dropbox.com

  - by Zongheng Yang

  Hi everyone, I assume those who are reading this page know what vimwiki and dropbox.com are and what they are for, so I might directly go into my confusion. The common way of setting a PRIVATE vimwiki on dropbox is simply let your vimwiki directories be under Dropbox folder (but not Dropbox/Public/ because it would be PUBLIC). Dropbox allows directly viewing html with dropbox.com/* url: for example a index.html can be accessed by url https://dl-web.dropbox.com/get/Wiki/html/index.html?w=bfead71a, being added after the file name a specified string, ?w=bfead71a. Hence, if inside index.html there is reference to A.html, which is located in the same folder index.html is in, it has to be accessed using some url like https://dl-web.dropbox.com/get/Wiki/html/index.html?w=SPECIFIED_STRING. But it is seemingly impossible to hack vimwiki in order to make the hrefs in converted htmls corrected in this way. Is there some approach that can resolve this problem? I hope I make myself clear. Had you any questions, please ask me for further explanations. Thank you!

• How can I make the NetworkManager work?

  - by Yang Jy

  I am running a version of RHCE6 on my laptop, and lately I've been trying various stuff about network configuration through command line. Last night, I tried removing the NetworkManager using "yum remove NetworkManager" from the system, so that I could have more control of the network through the command line. But the result is, I didn't manage to configure the wireless connection through wpa_supplicant, and I need wireless connection during my travel to another place. So I need the wireless function back as soon as possible. I typed " yum install NetworkManager", some version installed, but I don't get to have an icon on the taskbar, and of course, the network doesn't work. The package I previously removed(about 24MB) was much larger that the one I just installed(about 2MB), so I think some dependencies must be missing. How could I install all these dependencies? Please help!

• CUDA: cudaMemcpy only works in emulation mode.

  - by Jason

  I am just starting to learn how to use CUDA. I am trying to run some simple example code: float *ah, *bh, *ad, *bd; ah = (float *)malloc(sizeof(float)*4); bh = (float *)malloc(sizeof(float)*4); cudaMalloc((void **) &ad, sizeof(float)*4); cudaMalloc((void **) &bd, sizeof(float)*4); ... initialize ah ... /* copy array on device */ cudaMemcpy(ad,ah,sizeof(float)*N,cudaMemcpyHostToDevice); cudaMemcpy(bd,ad,sizeof(float)*N,cudaMemcpyDeviceToDevice); cudaMemcpy(bh,bd,sizeof(float)*N,cudaMemcpyDeviceToHost); When I run in emulation mode (nvcc -deviceemu) it runs fine (and actually copies the array). But when I run it in regular mode, it runs w/o error, but never copies the data. It's as if the cudaMemcpy lines are just ignored. What am I doing wrong? Thank you very much, Jason

• Article search engine in php

  - by Jason

  Hello, I am using sphinx as a search engine on my website its working perfect and I have no complain with it. The only thing it lacks is, it does not allow me to search articles whose query length is more than 15 words. I know in reality people don't use more than 3-4 words i want to use it for finding duplicate contents. I was wondering if there is any alternative solution to sphinx. I want to cope with duplicate contents. My main articles table is in innodb but I am also caching articles into MyISAM table as well for full text searching but when I search an article it takes ages to perform one search. Its not the query problem, i think mysql lacks the fulltext searching facility. Thanks Jason

• Setting a cookie before Javascript Redirection

  - by Jason

  Hello, I have a Rails app where I set a set a session variable the moment a user lands on my site with the referer and the page they hit. Additionally, I have Google Optimizer sending traffic from my homepage to various landing pages. The problem is that I think Google Optimizer is sending users away before the cookie is set. Is that even possible? I believe that the cookie is set from the HTTP Header, which must have fully loaded before Google's Javascript has even loaded. Thanks, Jason

• Named Blueprints with factory_girl

  - by Jason Nerer

  I am using Factory Girl but like the machinist syntax. So I wonder, if there is any way creating a named blueprint for class, so that I can have something like that: User.blueprint(:no_discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader false name "foolish" salt "21746899800.223524289203464" end User.blueprint(:discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader true name "deadbeef" salt "21746899800.223524289203464" discount_rate { DiscountRate.make(:rate => 20.00) } end DiscountRate.blueprint do rate {10} not_before ... not_after ... end Is there a way making factory_girl with machinist syntax acting like that? I did not find one. Help appreciated. Thx in advance Jason

• Click GEvent.addListener with jquery

  - by Jason

  Created a google map with GMap2 and put pinpoints on there that open up a balloon with the address when the pinpoint is clicked. I would like users to be able to click text on the page itself and use jquery to open up the corresponding balloon. However I can't figure out the ID to use to call a jquery click event. Basically I've got a store listing down the left side and when user clicks store name I want it to open up the corresponding balloon. GEvent.addListener(marker_500, "click", function () { map.openInfoWindowHtml(point, myHtml); } Any idea what element tied to this click event is? Tried $("#marker_500").click(); And that doesn't work. Also tried alerting $(this).attr('id'); inside the click function and that is undefined. thanks jason

• Javascript array of href's

  - by Jason

  Hi, I am trying to create an array with different href's to then attach to 5 separate elements. This is my code: var link = new Array('link1', 'link2', 'link3', 'link4', 'link5'); $(document.createElement("li")) .attr('class',options.numericId + (i+1)) .html('<a rel='+ i +' href=\"page.php# + 'link'\">'+ '</a>') .appendTo($("."+ options.numericId)) As you can see I am trying to append these items from the array to the end of my page so each link will take the user to a different section of the page. But i have not been able to do this. Is there a way to to create elements with different links? I am new to javascript so I am sorry if this doesn't make a whole lot of sense. If anyone is confused by what i am asking here I can try to clarify if I get some feedback. Any solutions would be greatly appreciated. Thanks, jason

• ASP.NET Web User Control with Javascript used multiple times on a page - How to make javascript func

  - by Jason Summers

  I think I summed up the question in the title. Here is some further elaboration... I have a web user control that is used in multiple places, sometimes more than once on a given page. The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers. However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on. What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss. All comments greatly appreciated. Jason

• glibc backtrace - can't redirect output to file

  - by Jason Antman

  Hi, I'm in the process of debugging a C program (that I didn't write). I have all of the internal debugging tools (a whole bunch of printf's) enabled, and I wrote a small PHP script that uses proc_open() and just grabs both stdout and stderr, and time-coordinates them in one file. At the moment, the binary is dieing with a realloc() error that's caught by glibc, and a glibc backtrace is printed, beginning with: *** glibc detected *** /sbin/rsyslogd: realloc(): invalid next size: 0x00002ace626ac910 *** Here's the thing I don't understand: I've confirmed that the PHP script is catching both stdout and stderr from the binary's process and writing them to the correct files, but this backtrace is still printed to the console. Where is this coming from? Is there some magical output channel other than stdout and stderr? Any ideas on how I go about capturing this backtrace to a file, or sending it out with stderr? Thanks, Jason

• two arrays defining 2d coordinates, as array indices, in matlab/octave

  - by Jason

  Hi, I have a 2D array, call it 'A'. I have two other 2D arrays, call them 'ix' and 'iy'. I would like to create an output array whose elements are the elements of A at the index pairs provided by x_idx and y_idx. I can do this with a loop as follows: for i=1:nx for j=1:ny output(i,j) = A(ix(i,j),iy(i,j)); end end How can I do this without the loop? If I do output = A(ix,iy), I get the value of A over the whole range of (ix)X(iy). Thank you, Jason

• Is there a way to add an elmah rss feed to google reader?

  - by Jason Irwin

  Elmah has an rss feed and rss digest feature. My feeds are working just fine from within my brwoser. However I would like to add them to google reader as this is my feed reader of choice. The problem is that Elmah uses an AXD handler to server its information - therefore the path to the RSS feed is not a physical one. For example the RSS feed for my site is located at: http://www.mysite.com/errors/elmah.axd/rss This is not a file nor does the folder structure exist - it is all part of the beauty of Elmah. When I attempt to add this virtual path as a feed in google reader i get: Your search did not match any feeds Any help would be greatly appreciated, Thanks Jason

• ASP.Net Form Databound problems

  - by Jason Bitman

  I know there is a similar problem on this forum, but the solutions did not really work for me. I am populating form controls with fields from a few different data sources, and the data shows up great. I have an ImageButton controlwhich has an OnClick Event set to grab all of the data from the form. Unfortunately, when I click the button, it seems as though the page is reloading first, and THEN is executes the OnClick call. The data that was hand-entered, or hard-coded seems to be pulled fine from the controls it was entered in, but anything that was pulled from a datasource is not able to be read. Any ideas. this is the last hurdle in a project that I have been working on for 6 months. I want to go home... Thank you so much in advance. Jason
