Comment Spot on (Score 1) 190

I think the article is spot on. I like the RPi, and have several, but by the time you buy all the supporting equipment, it's no longer the bargain it sounds like. The article shows clearly to all that the main CPU is no longer the expensive component of a total working system like it was for the PC era.

Many complaints about the article compare it to the effort computing took back in the TRS-80 dayz. While it may be comparable in difficulty to what we had back then, it misses the point that this is supposed to be an entry system for poor, casual users and unsophisticated beginners, not hard-core nerds like me and apparently many of the complainants.

If the designers were more savvy, they would have put a full-size male HDMI plug on the end and a female USB A on the other, with a minimal clamshell cover it all. Think Chromecast or Intel Compute Stick form factor.

If the device can work on back-fed power from a connected powered hub like the original RPi, that's even better as it eliminates another power supply and cable. Vendors could even advertise as RPi power compatible! Once you've found a suitable powered hub, all you'd need is that and a keyboard/mouse. And the display, of course.. and the MicroSD card.. and a USB WiFi or Ethernet device if you want to get online..

I really wish they would provide serial console access via the micro-B "power" port, too. I'd love to have a working system that I can power and talk to from my laptop. In fact, I'd love to have a whole server farm of them!

Yes, with all that, you'd overshoot the $5 price point, but the total cost would still be lower without the need for the HDMI and OTG paraphernalia... those cost more than the CPU itself now. If you could walk into a library with a small handful (RPi, microSD, and a powered hub) worth less than $20, power up the hub, plug it into their monitor/KB/mouse, and get your own login prompt, imagined the possibilities!

C'mon, kids! Sell your $150 sneakers, buy some $90 ones instead, get three RPi sets with your cash, and rope two of your nerdy friends into playing with you.

I would add that a setup like this can be a help drawing talented analysts to your operations center. People who like the Raspberry Pi are often the passionate type who live and breathe IT and security.

If I were working in (or running) such a place, I'd be enthused about setting up and maintaining a cluster of RPis, and would probably be staying late to just fiddle with it and test things out... Giving analysts a secondary project like that keeps them interested, gives them a sense of ownership, and helps to avoid analyst burnout.

Comment Re:mine is running from the TV USB port (Score 1) 197


The 2A stated requirement for the RPi power supply is assuming you're plugging in a couple devices that draw up to the max 500mA per port. Without those power hungry devices, the RPi itself runs well drawing less than 500mA from a standard USB port. I've also see them run stably with back-fed power from a powered hub...

I do know that some USB WiFi sticks are heavy current users, though, so one must shop around for specific brands. I also know that the Ethernet PHY draws a fair amount, but I have no setups that utilize it so don't know how well it works feeding off a TV's USB port.

Comment The guy is a squatter (Score 2) 190

If the current owner was actually using the name for his business, I'd agree with the majority of commenters in this thread. Say he had a consulting firm named "WorkBetter, Inc." and had been using it for years with business cards, receipts, and tax records to show for it. That does not appear to be the case here, as he has a list of domains that he's trying to sell. 117 of them by my count, including several with active trademarks and a few Daft Punk-ish variants of work-something.

This is textbook cybersquatting. He bought a whole bunch on speculation hoping to get rich quick, and now wants to cash in his lottery ticket. It's a little too late for him to claim he has a legitimate business use for it.

I know that's not the prevailing opinion here, but he's been squatting on the domain for years without using it. I think the company suing him has a legitimate case. It doesn't and shouldn't matter that he held the domain before the plaintiff registered their trademark; his continued holding of it is squatting.

Of course. Then do your check for zero before the division, if your latency requirements can handle it. If either option doesn't meet spec, then your specifications are where the "bug" is...

I kinda assumed that if someone is looking for a CPU to assign a number when dividing by zero, he's not in a job where they're asking him to do low-latency signal processing. VisualBasic is probably a better fit for his career path.. ;)

sqrt(1^2) does not imply 1, nor does sqrt((-1)^2) imply -1, they both could be either positive or negative: sqrt(1^2)=±1

The last equality should appear as ±1=±1

Congratulations; you've hit on another undefined answer in mathematics and exploited it to make the rest of the uneducated think you're smart.. or something.

That is simply false. There are an infinite number of algorithms that might contain the (sub)expression X/X for which zero is a valid value of X. To assume it's a programming error is sheer unmitigated stupidity that I might expect from a mathematician that has never written a real program in his life.

As someone with a degree in mathematics and a degree in computer science (with special academic honors, I might add), I strongly disagree. Fix your damn program to check for a dividend of zero, or at least trap the exception and handle it then. If NaN or any of the infinities are useful in your computation, do it outside the normal math libraries or choose a language that explicitly permits them.

To assert that it's not a programming error is sheer unmitigated arrogance that I might expect from a code monkey who barely scraped by his high-school math courses, assuming you even attended any.

And yes, I've made my living writing programs, many of which benefitted from my knowledge of higher mathematics.

While Redmine definitely has plenty of plugins and features for "agilism," it's easy to bypass or ignore them. It also allows SSO for Windows users with fallback to user+password, sends change and assignment notices by email, and has a Wiki built in. You can auto-create recurring issues if that's needed (think assigned weekly/monthly tasks), and there's a knowledge-base plugin that we've also found useful. It is project centered, where you can assign subsets of users to projects when they're created, and archive cancelled or completed projects to remove clutter.

Obligatory The Newsroom opening sequence

I think every U.S. politician should watch this at least once a week, both during session and during their fundraising runs.

Returning to the topic, it sounds like you have until they turn 18 to make that decision. By then, they can consider all the pros and cons and make their own decision, right?

The Jabra Speak 410 is also an excellent USB speakerphone with feedback suppression. Works well with Lync on Windows or Mac, in my personal experience. This would require someone bringing their laptop into the conference room just to run the VoIP app of your choice, though, but is likely to be a cheaper solution than any Polycom phone.
