Hello Daniweb Community, I thinking about upgrading from my laptop to a desktop the main concern is either if I should buy one of build one. So as the title says this is mainly if I was going to build one. To start off, my main concern about building one is compatibility. I'm not sure on if I buy a motherboard that I can buy whatever CPU, Graphics Card, etc... I'm not sure if there is like a guide I need to go off and even then does it all come down to if it's compatible with the motherboard? I …

This is possibly a very strange question, and I'm not sure where to ask it! But is there anyone around that uses a standing desk or a treadmill desk, and can you tell us how it effects your productivity and your typing. Do you make more mistakes? Do you use a tramill when you're thinking, or reading? Does it make you more or less effective? I know it seems like a stupid question, but I am very serious, and very keen to find out peoples thoughts on the matter!

Hi! I'm making an app and I need to know how to set position of strings in java.

im trying to figure out why we are using binary computers insted of ternary. from what i can tell the only valid argument is the cost of storage. basicly for those of you who dont know that a ternary computer is, its a computer that uses three positions of the digital wave form as imputs so yo have +1 0 -1 interperated as 1 0 2 insted the the normal +1 -1 being interperated as 1 0. acording to my research there are existing storage mediums that are capable of storing 3 positions but they just cost more. i also …

First some background on what I'm working on. I have a particular service (Windows only) running on my computer, which is built using C#. Other than Control Panel > Management Tools > Services, I can also use C# programming to Start/Stop/Restart the said service. I use ServiceController class in System.ServiceProcess to do the above said operation. I also have a web application, which uses web methods to perform various methods using this service. For instance, I might have MethodA() in my service, and I can access it using a web application (HTTP) and perform operations, send and receive data etc. …

This post is a summary of a conversation I had the other day with an acquaintance of mine. It started out with him asking me what I do for a living and ended up with me having to choke back tears of laughter. I hope you have the same reaction although I realize that it might be one of those, "You had to be there" moments.

Earlier this evening, I had a conversation with a friend and colleague in the IT business. He runs his own independent computer consulting firm and we were trading war stories about customers, hardware vendors and work sharing. Work sharing, also known as "farming out" work that you can't do yourself due to your schedule, volume or lack of expertise. He shocked me when he made the statement that, "Not that many companies use Unix anymore." Huh? I must have looked as if someone wanted to purchase my firstborn when he said that because he emphatically repeated the statement. I took …

I bought a laptop for my personal use an year back.. Although, it was from a leading computers' manufacturing firm, I've gone through series of hardware failures within the one year. That's not the end, I was covered with warranty so I managed to replace the items which were malfunctioning or completely gone dead. Now I am out of warranty and am not wiling to spend any money for repairing or replacing it unless I get a minimum of 3-5 years warranty cover for hardware components from the manufacturer or any third-party trustful source at convenient charge.

On the other hand, Computers nowadays can be very helpful, but also can be used to steel information, terrorism, and other crimes. If we do make better computers, they will eventually fall in the wrong hands, and be a more efficient tool for bad. How do you think we can prevent it ?

Perhaps it's my role as the family computer guy that's leading me in this direction today but it seems to me that there should be Linux distributions that are age-oriented and age appropriate. Seldom do I see my parents-in-law playing a heated game of [URL="http://www.quake.com"]Quake[/URL] or doing any kernel tinkering, nor do I see them downloading, untarring, compiling and installing some piece of software for their system. No, Windows isn't the answer. I can't tell you how many times I've installed, reinstalled, reconfigured, de-virused, de-spywared and rebooted their computers over the past 10 years.

I've been fascinated by the recent series of Microsoft ads that go after Apple. On one hand I commended Microsoft for having a unified message in [URL="http://www.daniweb.com/blogs/entry4186.html"]Microsoft Gives Apple the Full Court Press[/URL]. On the other, I think the message is off kilter as I wrote in [URL="http://www.daniweb.com/blogs/entry4212.html"]Apple's Value is More than Skin Deep.[/URL] That's why a recent post on BusinessWeek, [URL="http://www.businessweek.com/technology/content/apr2009/tc20090415_602968.htm?campaign_id=technology_related"]Mac vs. PC: What You Don't Get for $699[/URL], caught my eye.

So the analysts are saying computers are going to decline in volume shipments this quarter, for the first time in ages. I'm not surprised. The circumstances are probably worse for the IT industry than they were last time this happened, in 2002. The people who make these things have made computers that work. That was, on reflection, a bad move. Think about it. In [URL="http://news.bbc.co.uk/1/hi/technology/7918621.stm"]this report[/URL] the BBC quotes people saying that replacement computers, if they slow down, aren't the same priority that they would be if the economy were doing better.

Few things are more cringe-inducing than admitting to your boss that you lost your company-issued laptop. No matter how careful you are about securing your computer, sometimes all it takes is a second for it to vanish in a crowded airport or bus. To increase the chances of getting your laptop back, consider installing tracking software designed to help determine where the computer is being used and possibly even who took it. Hopefully, your company would pick up the tab but, if not, the $50 or so you'll spend is worth it for peace of mind. Jessica Mintz of the …

The future of optical computing no less. Or how about DNA computing where DNA has been used to form logic gates and play tic-tac-toe to perfection? My favourite though, …

It was supposed to be Christmas in May, with technology company executives harboring visions of wallet-waving consumers dancing in their heads. The reason? The proposed tax rebates coming from Washington that would put up to $1,500 in many Americans back pocket, and hopefully send them out to buy things like computers, cell phones, and Blu-Ray DVD systems. Every politician from the President on down said the economic stimulus package would spark a spending surge that would keep the Americans economy out of recession and on the road to a strong recovery. Not so fast. A new survey of average consumers …

From what I'm seeing out here in the trenches, economists just can't seem to agree on the health of the U.S. economy, in general, and the technology economy, in particular in 2008. Last week's consumer numbers seem to suggest that people are still willing to break out the checkbooks and buy new computers, cameras, TV's and other tech-related consumer goods. CEO surveys are a bit more cautious, perhaps because marketing and research spending are flat so far in 2007. To give us further hope, a new forecast out this morning suggests that the manufacturing economy - - especially computer makers …

Yesterday I gave you some fresh numbers on Black Friday and the holiday shopping season.

I wrote in an earlier blog about the time I met and interviewed Bill Gates, the brains behind Microsoft. I cornered Gates outside a back door at the Omni in Atlanta in 1991, where he had just delivered a speech at Comdex. Leaning on a bike stand, Gates riffed for 20 minutes on the future of technology and how, technology-wise, we had just seen the "tip of the iceberg" and that the next 20 years would "change everything". Bulls-eye. With the Internet, GPS Systems, mass commercialization of cell phones, the iPod, and Google, among other barrier-crashers, Gates was right on …

Taiwan-based computer manufacturer Acer has some big plans to storm the top tiers of global PC companies with its announced acquisition plans of Gateway. Gateway, for those who don't remember, is based in Irvine, California, but started out on a farm in the Midwest. The acquisition plans call for Acer to purchase all outstanding shares of Gateway at $1.90 a share, putting the net total of the proposed merger at approximately $710 million. The Acer/Gateway plan, pending all the usual standard closing conditions on a deal of this size, could be done by the end of the year. The proposed …
