I've been thinking to adding the ability to update some code I've been working on from the internet. So basically writing some C/C++ code that on startup of the software looks across the next to a server to update itself. However I have no idea how to do this, can anyone point to to linux tutorials or examples which show how to do this?
View 3 Replies View RelatedI run a web server on Fedora 12, principally using Apache, MySQL, and PHP. I host a variety of sites, one of which is a family website that contains semi-sensitive personal data for several hundred extended family members, who all have access to the database-driven site.
Until now, I have been using a self-signed SSL certificate to encrypt the data as it is read and written back and forth from my database. Family members have simply had to put up with clicking past certificate warnings as they enter the site, as most browsers flag self-signed certificates as bad. It hasn't really been that much of a bother, but I'd love to do it more professionally. I have looked into buying SSL certificates, but it's a site I host for free and would rather find a cheap or free alternative if possible.
So I'm just fishing for ideas to work with. What are some alternatives to using SSL certificates for moderately strong website encryption? So far, I run only one host on the domain, but may eventually need encryption that would support multiple hosts. Or does anybody know a way to make self-signed certificates work on most popular browsers without being flagged as suspicious?
I'm developing a new command to be executed on the grub shell. However for some reason the .c file I added doesn't get compiled. How do I notify make of this new file?When you type in the make command, a load of gcc commands come up, where do these come from?
gcc -Ikern -I./kern -I. -I./include -I./gnulib -I./include -Wall -W -DGRUB_LIBDIR="/usr/local/lib/`echo grub/i386-pc | sed 's,x,x,'`" -DLOCALEDIR="" -DGRUB_MACHINE_PCBIOS=1 -DGRUB_UTIL=1 -MD -c -o grub_setup-kern_file.o kern/file.c
I know this because I typed in random letters but the compiler continued on. However tried it on an existing file it came up with a compile time error.
There could be some needs with to sync the linux box with my psion device :
- emails (iremails sync) <-> mutt or whatever works
- contact psion <-> abook
- data folder ~/home/username/mypsion <-> sync of data
Could someone help a bit in that sence? Is there a willing informaticien for that few lines of code, and make a new package or update/upgrade the irda-utils. Would be so helpful for the community (often, lot of users are moving to linux nowadays..)

It has happened with me before too! Few months back while working on Priority queue in C language, I successfully compiled the code and it gave the desired outputs, I showed the running code to my other seniors and committed it to the repository at 21:00 (I was in the office till late night), next day my boss asked to show the running code, and it didn't work!!! I updated from the repository whatever I had committed but still nothing worked? And then on this Saturday, my boss fixed a bug and committed to the repository and asked me to checkout which I did today morning, and when I ran the code it didn't work?

I am working on a project with a lot of vector math and I'd like to find a way to speed it up.eading about SSE, but I've found no explanation on how to actually use it in code (was looking for some kind of hello-world example, complete with compilation instructions).Does the gcc compiler automatically make use of SSE, if you add the -sse(2,3) option on the command line? Or are their specific functions/libraries you need to call?

It worked for a while and then I turned on Shift Switcher and a message popped up saying..."The new value for the button binding for the action Terminate in plugin Shift Switcher conflicts with the action Zoom Window of the Scale Addons plugin. Do you wish to disable Zoom Window in the Scale Addons plugin?" I was given the option of Set Terminate anyway, Don't set Terminate, and Disable Zoom Window. I clicked Don't set Terminate and ever since the only thing that works in compiz are the bindings in the general options. I've used synaptic to completely remove and then reinstall compiz but the problem persist. Something else weird, all of the changes I made are still there, even after complete removal, but they don't work?

View 8 Replies View RelatedI just recently (about an hour ago) installed Ubuntu Netbook edition on my old laptop, and I was greeted with the message, that unity could not be run due to some sort of missing driver...fair enough, I was then greeted with the default Ubuntu desktop, I installed all my needed software (wine, google chrome) and installed the missing display drivers. I then rebooted the system, and once again I am stuck with the default desktop, and not the Unity interface. I checked the software center, and it says Unity IS in fact installed.. And yet I cannot make it appear. So now I ask you Ubuntu veterans. How do I make it work?
