  1. Also, very important, make sure that you have the latest version of firefox and all the extra plugins installed .
  2. SELECT * FROM table1 LEFT JOIN tables2 WHERE table2.field1='id' What's wrong with that ? Somebody once told me that using subqueries is not the best way to work with SQL databases.
  3. Are you experiencing some downtime ? I guess gamma server? Because my website is not available anymore. HTTP is down, FTP is down, I can't even ping
  4. Well, I wouldn't have chosen Xisto, but it's much better than Xisto (which was a meaningless name imho).The new site is too large ! It took a minute to load and I have a 5Mbps connection at home. I'd also drop the background music, it's annoying (as is every background song on a website). And, I'd shrink the banner, it's just too big on 1280x800 (it requires constant scrolling as a part of the content is always offscreen).Other than those comments, it's a very good looking website ! Kudos to the designer
  5. Another interesting fact is that Java applications usually have a much larger memory footprint compared to c++ applications and when it comes to raw processing power, it's still slower as c++ (however, as mentioned earlier, it is also safer compared to c++).It's also true that java applications can run on every system that has a JRE, but that's not always true for java libraries. Accessing your webcam for example can't be done with a single library, you'll need one for every operating system.@iGuest1: well, there are enough tutorials online that explain how to write a java gui for manipulating databases. No doubt that there's on available for access databases (tough I think it's a lot more easy to just write an Access form to do this).@iGuest2: it can't be that hard to figure this out by yourself. Create a struct or class that contains the real and complex part of your number, then write the functions. It's probably not more than 20 rules of Java code

    Custom Pc Case

    Your pictures aren't realy telling much, tough I must say, it seems a lot better now (but that's not hard to do as the case was fugly to begin with ).@Spencer: you can use a normal AC power meter to measure how much power the computer is drawing. The cpu and gpu usually use most power, so it's best to let them crunch on something while measuring (use something like Prime95 to stress all the cores and a 3D benchmark like 3DMark to stress out your graphics card). The power usage of all the extra lights depend on what kind (LED, CCFL, ...), their size (10cm, 20cm, ...) and how many of them you're installing. Afaik, all devices specify how much current they draw (tough you also must take into account the fact that CCFL's might draw a lot of amps before while starting).
  7. I'd try to broaden your target audience, not only off-license stores might be interested in this app. It might surprise you, I've had almost exactly the same question from the parents of my ex girlfriend. They asked me if I could make a website with exactly the same information Instead of writing everything myself, I used Joomla, it has a learning curve, but once you're used to it, it's easy to use. Anyway, off-license stores are probably not the only ones wanting such a system, so try to make it easy customizable for other kinds of stores
  8. Since you already have a gmail address, it's probably the easiest to use Google Docs to upload your documents.Currently, you can upload any file up to 250Mb to Google Docs (and share them with other people if you want)
  9. Adding some newlines to your text could really make this a more pleasant thing to read. Like it is formated now, I don't even want to read it.Also, mind your spelling, I realize that English is not your mother tongue, but things like "wqhy", "appl e", "ipAd" and "NOt" are just things you can't afford to write (seriously, these things discourage me even more to read your text).
  10. It's not bad for a first time, tough I do have some suggestion 1) don't ask the user to input words like square, circle, ... Give then a numbered list with options and ask them for a number, makes it a lot more easy to figure out what the user wants. 2) As mentioned very often, don't use GOTO statements. They might look easy to use, but they are messy and they are slow as they need a lot more instructions to handle. It's better to use switch/case or a nested if-else construction. 3) Mind your casings: http://vcf-online.org/docs/ref_manual/ch01s07.html%23id4750221 so float psquare (float a)should be float pSquare (float a) 4) Also very important are the names you give to functions. The name of a function should tell everything it does. "vcylinder" tells nothing whereas "calculateVolumeCylinder" tells everything. 5) Take a look at how you can make classes. This is the power of c++ (as it is an object oriented programming language). Now you've made the first steps and now that you have all the functions, it's not a bad idea to group them in classes. So you could say double radius = 5;myCircle c = new myCircle(radius);cout << c.getVolume(); Keep up the good work and don't give up
  11. Wouldn't be very effective as you'll have to make sure that the other side of the stirling engine is cold enough. Also, as a stirling engine is a very inefficient thing to produce energy, a lot of energy is lost just because of the moving parts and the friction on those moving parts. Another problem is that the glass won't be able to handle the heat generated by the array. The idea of using a mirror array is not new though https://en.wikipedia.org/wiki/Concentrating_solar_power
  12. Everybody who is connected to the internet uses a public IP address, this address is usually assigned to your router. Your computers however, are configured to be in a private network and that's why your computer has a private 10.x.x.x address. The router does all the necessary translations so your private network is able to communicate with the public network. What you need to do is to setup port forwarding on your router. This simply tells your router that data all data arriving at a certain port (on the public address) must be forwarded to an certain pc in your private network. For example, if your public IP is 62.1.2.3 and you set port forwarding to forward port 80 to 10.154.22.136:80, everybody surfing to http://forums.xisto.com/no_longer_exists/ will be redirected to YOUR computer. Your public ip: https://www.whatismyip.com/ Port forwarding: https://portforward.com/
  13. Omfg, some people are just idiots.Who would someone want to hit Haiti with an earthquake ? Imho, if someone wants to test these HAARP techniques (whatever they might be), then they'd probably do it in the middle of the ocean (kinda stupid as might cause floods elsewhere) or on an godforsaken island where no harm is done to anyone (but nature itself)
  14. MacOS has many faces, tough nowadays it's nothing more than an x64/x68 operating system. A server doesn't need 70 NIC's and thousands disks by definition, a normal pc with a single NIC, a single disk and a single CPU can be a server too. A company with only 5 workers doesn't need a big server, they're probably better of buying a descent computer, installing linux or windows server on it and using it as a server. The only difference between a server and a workstation is that most of the time, nobody is (physically) logged in to the server and that it can be headless and inputless most of the time. And of course, a server has to offer some services to user, like a webserver, database server, svn server, mail server, ... //edit: btw, I have two servers running at home, both are using debian, works great . //edit2: I do have to admit, a real server is different than your average computer because it uses more expensive hardware that won't die after a year of heavy usage.
  15. Then he'll have 800 simultaneous downloads running at the same time
  16. There is a reason why you have to update messenger from time to time, not only because they add functionallities to newer version, but also because they patch potentional security flaws. Thus, by not upgrading you're taking a risk .Also, you're fooling other clients into believing you have a newer version of messenger and that it also supports the new features that came with this version. Thus, some features might not work anymore after doing this.You can't keep procastrinating an update and once you're realy forced to update, you'll probably feels worse.
  17. Uhm, yeah duh! How can you not have heard about Haiti ? It's everywhere right now, radio, television, newspaper, internet, ... Everywhere campaigns arise to raise money for Haiti, a few days ago all radio channels cooperated and formed one single radio station (Radio 12-12) to raise money for Haiti.Advertisement banners are replaced by 'help Haiti' banners ...
  18. Well, for personal use or from a business point of view it would be completely useless to backup the internet (unless they ask money for recovering websites by using their backup, but only few companies will use it ).For research purposes it might be interesting, tough I can't really think of a good research question right now that could use the complete internet It doesn't have to make your website unreachable. If one has a Gb downlink to download 100 different websites at a time, he'll use (rougly) 10Mbps of your website's bandwith. Nothing to worry about
  19. Or about 2 years if you can afford a FTTH Gigabit connection
  20. 5 years from now you might archieve the internet as it is now, but not they way it'll be in 5 years
  21. I was going to suggest the Microsoft Live Parental Control things, but I guess that won't work on a Mac ;)The keylogger you suggested isn't going to protect your child as it only logs what they do instead of blocking things they shouldn't be doing.

    Hello

    Most names have a meaning. Back in the days, most people's names meant 'son of' or 'daughter of' and sometimes even referred to the profession of the father or the person itself.
  23. With your 4Mbps download speed you'll never be able to keep up with all the data that is put on the internet daily, especialy on sites like Youtube (do note, Youtube uses 7.7PB for storing all the data, but of every video they keep the original plus a 360p, 480p, 720p and 1080p version where possible, the most efficient way would be to either store the highest resolution video or the original video).The next problem is power consumption. A single disk doesn't use a lot of power, especialy compared to a modern cpu. But 1000 disks easily use a few KWatts, generating tons of energy which you have to cool down.You'll also need a huge room for all the racks and for extra free air for cooling purposes (a backup).Imho, it's impossible to do.
  24. Look it up in the package manager If you installed apache2 using the package manager then installing php is a piece of cake. I'm not sure what package manager opensolaris uses, but I tought it was aptitude. With aptitude search php5 you can find the right name of the php package for apache2 and using something like aptitude install php5-apache2 would be enough to install and pre-configure php .
