Unparallelogram

I have heard of networking over home power systems. They definitely work, but it's hard to say how well, and I imagine realistically it's far worse interference-wise and condition-wise than just wiring your home for ethernet or even wireless lan. (Note: this was before wireless lan became popular. I saw it in a computer catalog.) Power lines, even home power, would just mess with so much in terms of interference, and not be particularly good for transmitting signal even not counting the other (power) signals that have to go over them concurrently.

Actually, I WANT to reinvent the wheel. I want to get practice and build a portfolio of web apps that will show prospective employers that I know more than just theory and classroom assignments. I feel this should have some original stuff, but most things have already been done before, and that's probably a better show of programming skills than nothing.Should I be scanning the text input, or should I be doing searching? How do I minimize the amount of copying that goes on in memory? Are there string buffers? Does that even matter in the overall performance?Thanks for the link.

One of my friends jokingly did the math behind this after reading a humor post about a lady who asked for wireless power. While EM radiation can carry energy, and so you could theoretically transmit usable power through it, it is -- as expected -- largely impractical. Even assuming perfect efficiency (no dissipation, no loss, perfect focus), the magnitude of the waves you have to send would end up EMP-ing all your electronics, messing with your health, and more. Then there is the issue of how you would collect the waves at the other end, because realistically there will be so much dissipation and absorption along the way.I think we have to wait for some other form of energy transfer to be discovered, and realistically, I'm not expecting that to become practical either. If you really want to hope for good power supply ideas, maybe your best bet is cheap room temperature superconductors someday.EDIT: You CAN power TINY devices over SMALL distances this way. My graphics tablet uses magnetic induction to power the electronics inside its pen, so that it is both wireless and betteryless. But we're talking MILLIWATTS of power rate over CENTIMETERS of distance.

You would need...1. backend php script - which validates usernames/checks availability by doing database queries to MySQL2. frontend page - registration page like you're looking for3. frontend javascript - handlers for the forms on your page that call the backend and process the results to give the user a messageWhich part/s do you know/need to learn in particular? We could probably be more helpful if we knew which parts of the process you wanted to learn more about.Also, you may be better off using a prebuilt library on both the php and the javascript end, as commonly used things such as AJAX requests are commonly provided by libraries already. This saves you the hassle of dealing with the browsers and such.

I agree, if Windows Defender is any indication, this probably won't end well. Defender is the reason why I can't run large applications without significant (think TENS of MINUTES) startup lag. It also has a rather "interesting" idea of what is harmful software to my system and what isn't. Particularly, it tries to stop me from using what it thinks might lead me to someday pirate, whereas it's powerless to stop any "bad" software with a decent legal department backing it. Personally, I've had a bad experience with defender, especially since I can't seem to get rid of it, and I would hate to see a forced antivirus thing from Microsoft further slowing down Windows 7. The current 7 beta seems even slower and bulkier than Vista already, and I would be sad to see it worsened.

I like Fedora a lot. It's full featured and tends to have a bunch of newer stuff. Admittedly it's risky and not always stable, but it is usually one of the first major distros to get a package, and that tends to bring both new features and bug fixes. I probably shouldn't be relying on it for mission critical applications though, since it can break, and I had two weeks when I couldn't get sound in headphones because of a kernel issue. Thing is, when something breaks, the forum is quite helpful and there is usually someone who knows what's happening.I used Ubuntu before and it's nice too. They have the biggest user base of the major distros, and so they have possibly the best unofficial support turnaround. A regular problem could be answered in minutes, and even obscure issues usually eventually get found by someone else in a similar spot. It's great to have such a large number of people along with you in your journey.

There are boot sector viruses too, but those went out of fashion a long time ago. Now, I suspect it's hypothetically possible for them to resurge with the new popularity of USB devices, but nobody's seen one in the wild that I know of.But, the issue is rather that many autorun viruses will happily delete the existing file and write theirs over. They wouldn't care if they delete your legitimate autorun for whatever, nor if they rewrite their own over again.Disabling autorun may well be the best idea, especially since you can right click a drive and specifically select to execute its autorun if you need.

I was surprised to see this review. I believe this was my old phone, give or take a few model numbers, although with slightly different customization. I have since switched to a thinner model from the same Sony-Ericsson Walkman Phone line. I was reasonably happy with both models. As I see it...Pros:very good music, it really is Walkman technologyactually quite a good camera considering it's meant as a small ish phone (on the thicker model anyways, not my newer one)all the basic features of a modern phonewas free with contractCons:the w910i in particular is bulkier than your average phone, definitely bulkier than a Razr or suchquite expensive if your carrier doesn't subsidize the costAll in all, a great phone if music is your focus, and a good phone overall. Especially if your carrier offers it free, quite a nice deal, much like any other from the Sony-Ericsson Walkman line.

That's actually a pretty vague description. A lot of video game systems/personal computers of that time had similar designs to what you described. I don't know which one you're talking about, but my friend has a Commodore 64 which would fit the description, among other systems I'm sure. I'm not too familiar about the accessories, but you mentioned keyboard and that was my first thought.

I am planning to make a parser for BBCode and templating scripts. I am guessing I will be doing this in php as it is the most widely available language available for web right now. I am wondering if anyone has some advice on how I should structure this as to make it easier on myself. The thing is, while I would probably be able to make a full scale parser, that would be difficult and time consuming. Whereas, BBCode, template include declarations, etc seem like a far smaller subset of most parser languages.Really, I only need these features.1. Tag recognition. If I see a ( tag in the source it should know to convert it into a <b> html tag.2. Tag parameters. I need to be able to (include-template "abc.template") for example, and pass extra parameters into certain tags/calls.3. Tag matching. I need it to make sure that all tags are closed properly and nested in the correct order.Does anyone have ideas as to the simplest way to implement this?

Sorry if this is in the wrong forum. I am not entirely sure.It seems some forums say that they require user level 1 for posting. What does that mean and how can I get it? Thanks.

Depends a lot what method you're using to do the write. A lot of the methods are overloaded for not only strings but also raw bytes in various forms. It may be safest just to force a string conversion as myInt+"" or (new Integer(myInt)).toString() if you're going to be using it in a string context. The compiler is smart enough to convert for you in many cases, but unfortunately not all, and especially not when there is an ambiguity as to whether you want the string representation or raw numerical value.

People are afraid of change, especially people in large organizations with a lot of pre-existing systems to maintain. I think the biggest barrier to getting people in these organizations to use Linux for at least some tasks is how to make this change relatively easy and pain-free. There has to be better measures for transitioning not only software and data, which is the relatively easy part, but also users and their knowledge, which is far more difficult. Someone who has trained with, for example, Windows and Office, will have a certain learning curve going to, for example, Ubuntu and OpenOffice, even if the latter products seem to be using a similar design and interface. There's just a lot of smaller things that users have picked up over the years that they would not be happy to leave behind.

There was an outbreak of such a virus at my school this past year. That particular variety would not spread itself if your device already had an autorun.inf file, assuming that it had already spread to the device, and so some clever kids just started carrying around a bogus autorun.inf file on their devices. This is of course no substitute for antivirus and occasional hand auditing, but it reduced a lot of spread between unprotected computers.

I'm also wondering, are we able to set our own php.ini files just for our own directory? It seems magic_quotes_gpc is on, which while it is definitely possible to work around, gets really annoying sometimes. Otherwise, the phpinfo() seems pretty sane and more or less what I'm looking for. Thanks again, guys.

Intuitively, you're trying to move the first element to the end, then the second to last element (previously the last) to the front, using only swaps. So go from the beginning and swap adjacent elements down the line until you hit the end, then repeat again to get the other element back. You can swap the elements just like you would in any other linked list operation. Just move the current pointers into temporary variables and then exchange the corresponding pointers between two adjacent nodes.EDIT: It would help you to abstract the swapping function out.

I'm confused why my account has no listing for myCENTs.<-- I mean to the left. I have an account with the other account system and everything.

I'm not sure about the details, but php lets you set locales and then format things in such the locale. You should first call setlocale() to tell php what language to use for its outputs, including date formatting, then call strftime(), which gives a formatted time string. See for details: http://uk3.php.net/manual/en/function.setlocale.php http://uk3.php.net/manual/en/function.strftime.php

Hi guys,I'm new here today. I'm just a college student planning to go into computer science. So right now I'm trying to get some experience in web application development. I guess I have little bits of knowledge in various areas but my main worry is that there's nothing I know well enough to use in a job setting yet.I used to have a paid hosting account elsewhere that I used mostly for developing toy applications and learning programming skills. It was fun while it lasted, but I realized I didn't need all that host offered and was paying way too much for a site that only I and maybe a few friends at times ever visited. So now that account is cancelled and set to expire at the month's end, and I am off to find a new host.I'm kind of wondering what this place is like. I've asked around and heard a lot about sites that offer free hosting services to their forum members. I would be very interested in getting a smaller volume hosting package for mostly testing and development. I do have a few concerns though. I think I would need some services that have seemed a bit strange to some webhosts I've met in the past. For example, I have an interest in developing applications for Facebook, which communicates through making HTTP requests, both from them to your page and from your page to theirs. This requires, among other things, safe mode off and the allow_url_fopen directive. I was wondering if anyone could post the phpinfo() here.
