Comment Re:All encryotions is "breakable" (Score 1) 418

Only because you arbitrarily assign one half to be the ciphertext and the other the key, you could swap them and the result would be the same.

No. Then you would be sending your message in the clear and encrypting the pad. The point of OTP is that you can pre-share the pad, then later use it to exchange messages without the message being read by intercepting parties.

For the most part it's just as difficult to send both halves as one whole

You don't send them as a whole. You pre-share the pad (eg: tell your friend to use the prime-numbered pages of a specific edition of the bible), then you can freely send messages you've encrypted using that pad, up until the point when you've used up the pad.

As someone pointed out already, OTP is not really an encryption, but a way to split the information in half.

No, OTP is symmetric encryption where the pad is the key. You take your plaintext, transform it with the pad, and that becomes your ciphertext. Then you apply the same transformation with the same pad to the ciphertext, and the result is the original plaintext. The information to be sent should not be used for any part of the pad.

Comment Re:This is how they start. (Score 1) 142

Are we supposed to believe that nobody raised an eyebrow when the revision N+1 engines suddenly started turning in far better NOx numbers than the revision N ones

I expect they were trying to keep the numbers from getting worse, not improve on previous values. Revision N is churning out emissions that exceed acceptable levels, so they "optimize" the software to reduce emissions during the conditions in which the excess was observed. Though as you say, it was likely done under the direction of someone high up, with wink-wink, nudge-nudge approval from the rest of management.

If I were evil, I would have set it up so I could blame it on a junior engineer and still have us both come across as innocent. I would give him/her a set of inputs and say "The emissions are too high under these inputs, we need to reduce emissions for this edge case." The engineer adds a condition to handle that edge case, without ever knowing that one of the inputs is a flag indicating the engine is under test. End result? Plausible deniability - the engineer thought he/she did the right thing, and the manager "didn't realize" that one of the inputs was the value of the under_test flag.

Comment They're position is reasonable (Score 1) 198

they do not think that the position should have full access to the environment. It is an "architecture" position and not a "sysadmin" position is how they explained it to me.

That seems reasonable for a moderately sized company with the infrastructure you describe. Your analogy of drawing a map without being able to visit the area is a very good indicator of the miscommunication occurring here - you need to be able to see all the infrastructure, but you're asking for full access. To use an imperfect car analogy (this is Slashdot after all), you need to be able to lift the hood and see the engine. That's reasonable. You're asking for full access to change all parts of the car. That's overkill, actually implementing changes is outside the scope of your responsibilities.

A requirement of any senior role is the ability to delegate responsibilities and trust the input from your team and other managers. I suggest that as an architect you should be asking the IT core team for the network maps, system configuration lists, etc that you need as inputs for your design decisions. You can then respond with changes that are needed to their systems. In your new role you would have the authority that your changes are requirements not suggestions. However the responsibility to make those changes still rests with the IT core team - you don't need and should not have access to make those changes yourself.

I like to think of architect roles as consultants with authority. You give them the best documentation you have, and maybe read access to the systems. They come back with recommendations for changes, while architects have the authority to state them as requirements instead of just recommendations. But just like you wouldn't give an external consultant full admin to your systems (eg: domain controllers or databases), you wouldn't give it to an architect.

Comment FYI radio astronomers: Beware dodgy microwave oven (Score 4, Funny) 27

It's all well and good to enforce radio silence in the array's general area, but I hope they employ common sense as well. It took one batch of aussie radio astronomers 17 years to figure out that their dodgy microwave oven was causing intermittent interference; hopefully these guys aren't so clueless as to use unshielded electronics in any proximity to the array. Shielding your data centre is great, but it'll be the guy who forgets to turn off his cell phone that messes up your signal.

Comment I'm getting 8 hrs, but my body wants 9 - 10 hrs (Score 1) 159

I have three little kids, the youngest not yet one year, so I'm unable to get all the sleep I'd like. I make do with about 8 hours a night, sometimes only 6 or 7. But on the very rare occasion that I'm away from the kids, I naturally sleep between 9 and 10 hours (and feel much more awake in the morning.)

Of interest might be my kids' sleep times: 9 hours for the six year old, 10 hours for the four year old, and 7 hours plus multiple naps for the infant.

Comment Not XKCD, but oblig PowerNap reference (Score 1) 407

Sounds like we'll end up in the situation described in Power Nap, where everyone takes sleep supplements to stay awake. Except poor Drew, who's allergic to them, hence providing the story's initial premise.

In some ways the idea of sleep supplements is very enticing, as we could do a lot more if our bodies didn't need to rest for at least 1/3 of each day. Misusing Adderall is along a similar vein, where the purpose is to stay productive and keep your mind sharp for longer than is usually possible. If there were no negative effects this would become a common practice and acceptable, rather than an addiction that needs to be treated.

Comment Re:One good thing about star wars weapons (Score 1) 274

The regular lead bullets from even a small caliber short barrel weapon is too fast for eyes to see. But the speed of light phasers being fired by the storm troopers leave a neat clean visible tracer lines. That leads straight back to the location of the gun which helps Harrison Ford ample time to find good spot to dive into, no antique plane needed.

I can't believe I'm replying to a joke post but... (a) you're mixing your movies, phasers are Star Trek and blasters are Star Wars. (b) Blasters supposedly shoot charged plasma - you fill them with gas, they excite it to a plasma somehow, and the glowing plasma is what's shot at the targets. Don't ask me about turbo lasers on capital ships.

(Cue a follow-on stream of comments correcting mistakes I've made, lol.)

Comment Flirting (Score 1) 698

I really wish my dad had talked to me about girls. Not the birds and the bees bit, but about how girls and boys are both the same: afraid to get their feelings hurt, unsure how relationships should progress, often hurtful to others by accident. He could have explained that the easiest way to let someone know you like them is to smile and say "Hi" every time you see them. To not be afraid of physical contact like dancing or holding hands. That even if you say or do the wrong thing, make an embarrassing mistake, if the other person likes you they'll still like you afterwards. That a good first date involves just spending time together talking and getting to know one another (and that I should therefore avoid movies for a first date!) It took me years to figure that stuff out, and looking back I can see a dozen points in my life where a simple explanation from my dad could have opened my eyes and saved me grief. Thankfully my wife recognized that I was clueless the moment we met, and simply told me how she felt.

Comment Re:Moved themselves out of the market (Score 1) 242

In Canada, the Radio Shack name was sold off years ago to Circuit City, and then when CC went under, bought up the Bell telco conglomerate, rebranding the stores as 'The Source' as another place to sell their cell phone packages and accessories. It looks familiar to Radio Shack, without any of the glory day components available for sale, selling cheap RC cars, computers and terrible audio equipment. The majority of stuff was labelled under a knock-off looking "Nexxtech" brand name. Again, inferior quality, but top-notch pricing.

So that's why I can't find anything useful there. I came back from New Zealand a few years ago, and was told by friends that Radio Shack was now "The Source", but when I went in they no longer had any of the stuff I needed. No bins of resistors or alligator clips or motors. No rolls of speaker wire, phone or network cabling. I have yet to find a replacement store that stocks hobby electronics like that, and I don't see the point in buying $5 of resistors off ebay and having to pay more than that in shipping.

I'm in the Canadian maritimes, if anyone has any recommendations for a new place to shop, I'd appreciate it.

Comment Article summary: Use time-in more than time-out (Score 1) 323

The point of the article is made near the end, which is to use less time-outs (which should still be used, as a time of reflection), and more "time-ins", which is apparently teaching your child about emotional events as they occur through the day. Based on the examples given, I would guess "time-in" is something we already do with our kids; it's just talking over events like "Wasn't it funny when Sarah sneezed milk out her nose?" Then listening to our kids tell their version. The new thing is to somehow "teach" them what that emotion means. I'm OK with a psych doing research that confirms common parental practices work, but there was a lot of vague hand-waviness about "teaching" emotions, and they skimmed over the fact that once a child is in school or daycare, the majority of their daily events aren't shared with their parents. Discussing such events therefore requires discovering them, which is difficult when the response to "How was your day at school?" is a terse "Okay".

PS: I actually read through TFA, which was rather long and filled with the author's opinions more than the psych's study results and opinions.. I don't recommend reading the article by the way, it was a lot of filler text with very little discussion of the main topic. It could use an editor's review - for example, it alternates between "time-out" and "timeout". Plus the title is misleading - it explicitly says time-ins aren't a counter-point to time-outs, it simply encourages that time-ins be added to the daily routine.
