I need to get internet from one building to another: let's say building 1 to building 2. The problem is that building 2 is approximately 1000 ft. away from the modem/switch in building 1. I've done some research and determined that it's not a good idea to just run a cat5e cable the whole length (due to loss), and it's not practical to boost the signal partway through (since the wire will be outside). I've thought about using baluns, but I'm not sure if they make them for that application, or which ones would work. Is there any other way to boost the signal so that one wire could be used? A different kind of wire perhaps?
Any suggestions would be appreciated. Thanks! - Pete5x5 ( talk) 00:54, 7 July 2009 (UTC)
Why not use several cables and connect each one into a hub or someshit to boost the signal half way through —Preceding unsigned comment added by 82.43.91.128 ( talk) 07:10, 7 July 2009 (UTC)
Thanks for the suggestions. The budget is $4000 or less (preferably less, but I have a very nice budget for this project). I would prefer not to join multiple cables, but before this that's the only way I could think of. I will definitely look into the 'ethernet extenders' you speak of. Hopefully there's a way to do it with only one wire. I think the technology must exist for that amount of money.. - Pete5x5 ( talk) 07:35, 8 July 2009 (UTC)
is there any way i can install pspwxp using wobzip.heres the address http://wobzip.org if there is can sombody pleaz give me a link to download it and instructions on how to download it. thanks
I only have about 6.5 GB left on my hard drive, so I deleted 3 GB worth of files and put them on discs, then I checked my memory, and it still said 6.5 How can I get my space back? --- Scarce |||| Talk - Contrib.--- 04:14, 7 July 2009 (UTC)
If you burned them to disc your CD/DVD writing software may have created a disc image on the hard drive first before burning the files. The disc image will take approx. the same space as the original files, hence you don't see a change. Try searching for ".ISO" files or check your preferences of your burning software to find its "temporary" or "working" folder and delete the disc images from there. Zunaid 10:59, 7 July 2009 (UTC)
Is there such a thing as chipset flashing? Is it different from BIOS flashing? Or do I just mean updating the chipset drivers? Thanks 78.149.207.75 ( talk) 09:25, 7 July 2009 (UTC)
When creating a map on InstantAtlas I get an error when uploading my .xml data file ( something about Attribute version having a fixed value of 1.2) so I create a demo data file instead. I can then replace the data.xml file with mine in the location I save it. On opening the map with my data file the data that should be displaying on the map doesn't, it just says no data in the comparison table, under the headings I used, and there is nothing in the ordinary table. The map highlights the Popp areas of my map in black when i hover over them. Any ideas? —Preceding unsigned comment added by 195.49.180.146 ( talk) 09:50, 7 July 2009 (UTC)
Ignoring the lack of error checking code, would this be the proper way to do this?
typedef struct
{
int data;
} Mystruct;
Mystruct * lotsaStructs;
lotsaStructs = calloc(10, sizeof(Mystruct *));
lotsaStructs0 = malloc(sizeof(Mystruct));
lotsaStructs0].data = 5;
Thanks! Horselover Frost ( talk) 13:53, 7 July 2009 (UTC)
lotsaStructs = calloc(10, sizeof(Mystruct)); lotsaStructs[0].data = 5; ...
Mystruct ** lotsaStructs; lotsaStructs = calloc(10, sizeof(Mystruct *)); lotsaStructs[0] = malloc(sizeof(Mystruct)); lotsaStructs[0]->data = 5;
Mystruct*
, so you need to write Mystruct**
Secondly when you're accessing data
via lotsaStructs[0]
that's an individual Mystruct*
, so you need to dereference the pointer before retrieving the element: C uses the ->
shorthand for that, although the line (*lotsaStructs[0]).data = 5
does the same thing (and makes the deref and the .data separate). Don't worry if this seems ridiculously complicated; once you understand this, there's really nothing left in C that's hard.

14:50, 7 July 2009 (UTC)Can anyone help with this? Until a few days ago, I had no problem accessing Wikipedia through my iPhone. Now, I just can't. It starts opening en:, seemingly redirects to "en-gb [something - it flashes fast past this] and throws up a "Cannot Open Page" message. I have no problems accessing other websites. Cheers. -- Dweller ( talk) 16:02, 7 July 2009 (UTC)
OK: a totally random theory: have you set something on your iPhone's settings to have your language be British English? It might automatically change en to en-gb. Unlikely, but a possibility. Thanks, gENIUS 101 21:02, 7 July 2009 (UTC)
Still unable to "get in" - this has been going on for days now. The specific error message is "Cannot Open Page Safari cannot open the page because the server cannot be found". The url in the address bar when it finishes failing to load is http://en.wikipedia.org/wiki/ [whatever I've tried to open]. I can try downloading that app (does it support logged-in editing too?) but many others will just want to browse Wikipedia and not be able to access it. I've not changed any settings in my phone - it's just too much of a coincidence that it's happened simultaneously with the mobile site changes, so I suspect it's not my phone but the way the change has been implemented. -- Dweller ( talk) 11:26, 9 July 2009 (UTC)
Mouse problems - just doesn't work right
Used to select with left button, hold left button and move to select a block.
Now mouse selects with right button (sometimes), left button causes block selection from last mouse position, scroll button doesn't work...
Same on another mouse.
No such control exists in windows to do this that I'm aware of?
I just tried open office - is this program known to fuck up windows??? Because I've never had anything like this before, maybe it's a virus, anyone know?
Appears to be the "stuck shift key problem" - what causes that - is it open source software? ? —Preceding unsigned comment added by 83.100.250.79 ( talk) 21:48, 7 July 2009 (UTC) 83.100.250.79 ( talk) 21:10, 7 July 2009 (UTC)
The "choose a topic" at the top right of the page keeps dissapearing - sometimes it's there. sometimes it's not, sometimes it pops in, and pops out. I also had the problem above - has anyone else got this, or is my computer just screwed up (IE7) 83.100.250.79 ( talk) 21:31, 7 July 2009 (UTC)
Is there another way to count the amount of rows in a table then using mysql_num_rows? When the rows get passed 5000+ and that query is ran it can cause slowness. —Preceding unsigned comment added by Ivtv ( talk • contribs) 23:02, 7 July 2009 (UTC)
$row=mysql_fetch_array(mysql_query("select count(*) as howmany from mytable"));
$number_of_rows=$row["howmany"];
$table=mysql_query("select * from mytable");
$number_of_rows=mysql_num_rows($table);
Yeah. I keep forgetting about count. Thank you for your example. Only thing I would change would be the wildcard because its terrible on a query especially if you are just trying to get one specific piece of data. Should just query your key in this example. You know this though, and you were just giving an example so I thank you. Works perfect

I was just wondering if there are any known linux distros that uses the concept of " Service Packs"?: something that can can be installed in a graphical and easy way, to update your system? (besides my own distro). Thanks __ Hacktolive ( talk) 23:47, 7 July 2009 (UTC)
