It boggles the mind, doesn't it.

One of my favourite interview questions is "What's your favourite data structure, and why?", and when they answer, I ask "How would you implement it?"

For something like 80% of the candidates I've interviewed, the answer is usually "erm...."

The vast majority of the remainder say "ArrayList" but don't usually say why.

Out of those, I've only interviewed one who could give any kind of basic indication that they knew how to implement one.

The state of the industry is shocking.

What, we don't think that Lync and everything else that offers a chat server in your own rack can't be configured to do this?

Hell, at my last office, they were feeding all our VoIP calls through this SIGINT app ; the only reason I found out was because I was copied in on ICT change reports for operational reasons and one of the changes was they moved the storage for the VoIP calls to another server.

Presume that you're being watched. You likely are, by someone.

Screw that.

Keep the card in a foil lined sleeve. You can get a pack of five for a few dollars, or get a fancy shielded wallet. I quite like the look of the ones made of woven stainless steel thread. I tested the el-cheapo ones that are just card and foil and they prevent card reads from all the readers I tested.

Then your physical removal of the card from it's sleeve is required to complete any transaction, contactless or otherwise. No-one will have a reason to amputate your finger.

If you scan things into Apple Pay it's not a copy of your card (unless someone seriously fucked up when they designed the crypto schemes for your payment card). You have to trust Apple, who are no doubt greatly enjoying the information about your payment history.

I was unaware CVS had any way to do this

CVS is just a layer on top of RCS. RCS stores all history for a given file, in a file in the RCS store named for that file.

Therefore to purge all history for that file, you delete it's repository file. Tada! Gone.

CVS is just a layer on top of something designed for single file programs, and it shows. It doesn't handle renames well. It doesn't handle getting arbitrary revisions of entire projects well. The more files you have in your project, the more overhead you'll consume attempting to track global project revisions.

SVN does at least fix some of that.

I found a lot of these problems were resolved by doing a system cache wipe ; it went from hardly charging at all to charging in sensible time. Currently the tablet has been sat lurking in an IRC channel on my nightstand, off charger, for at least a week, and still has more than 40% charge.

The only cable problem I had was when I dropped the thing on the floor when charging ; I had to rebend the shroud on the USB socket back into place. It's still a bit loose, depending on the cable you use.

Yes, you shouldn't have to tinker with things. I can't say I'm impressed with the overall quality of Asus's tablet offerings - my girlfriend has one of their transformer tablets, and the keyboard dock has failed - the connection seems to work fine, because the touchpad part still works... just the keyboard doesn't.

US Navy Develops Robot Boat Swarm To Overwhelm Enemies 142

Posted by samzenpus
from the angry-bees dept.
HughPickens.com writes "Jeremy Hsu reports that the U.S. Navy has been testing a large-scale swarm of autonomous boats designed to overwhelm enemies. In the test, a large ship that the Navy sometimes calls a high-value unit, HVU, is making its way down the river's thalweg, escorted by 13 small guard boats. Between them, they carry a variety of payloads, loud speakers and flashing lights, a .50-caliber machine gun and a microwave direct energy weapon or heat ray. Detecting the enemy vessel with radar and infrared sensors, they perform a series of maneuvers to encircle the craft, coming close enough to the boat to engage it and near enough to one another to seal off any potential escape or access to the ship they are guarding. They blast warnings via loudspeaker and flash their lights. The HVU is now free to safely move away.

Rear Adm. Matthew Klunder, chief of the Office of Naval Research, points out that a maneuver that required 40 people had just dropped down to just one. "Think about it as replicating the functions that a human boat pilot would do. We've taken that capability and extended it to multiple [unmanned surface vehicles] operating together within that, we've designed team behaviors," says Robert Brizzolara. The timing of the briefing happens to coincide with the 14-year anniversary of the bombing of the USS Cole off the coast of Yemen that killed 17 sailors. It's an anniversary that Klunder observes with a unique sense of responsibility. "If we had this capability there on that day. We could have saved that ship. I never want to see the USS Cole happen again."

Yeah, I can really relate to this.

The decent chaps (particulary ones who naievely point out "not all men..." before discovering this is like a red rag to a bull) are the ones who attempt to engage positively with these issues.. and because they are the ones trying to engage, they are often in receipt of some of the unpleasant feedback that should really be going to those other guys.

The problem is that once bitten, twice shy - it inclines most of us to back away and not prod that particular hornet's nest again. Which is a shame, because the idiots who create these problems in the first place are far more likely to listen to "bro's before ho's" - getting more of the decent men on side and active against their idiot step-brothers would be a victory for feminism.

I was really encouraged to see this point of view put forward by Emma Watson in her speech.

Both sides have something to learn - the well-meaning men need to learn that they don't need to engage with the women - they already *know* about discrimination. They need to engage with the misogynists.

And the feminists could help matters by swallowing some of their totally understandable rage and politely explaining this to us, instead of biting our heads off.

It's more of a task-switching thing for me.

I have multiple contexts I work in during the day. Each time I change tasks, but don't want to close the windows for the task I was doing before, I move to a new desktop. That, plus one desktop devoted entirely to communications (email, social media, etc), and I can switch between contexts with one or two ctrl-alt-arrow key combos, rather than painstakingly reconstructing the window layout each time I switch.

Until the OS supports saving a group of apps, complete with window position, open documents, etc (which would require a lot of app support), this is the best solution to task switching I've got.
