Does the book discuss my favorite workflow automation, git-flow? Other than in the obvious sense, like fundamentally "git flow feature finish 2012-11-26-whatever" basically just runs 3 to 6 git commands on the 2012-11-26-whatever branch and the develop branch although I can't be bothered to remember which commands exactly?
I thought Best Buy was Amazon's brick and mortar showroom?!?
I tried something like that and it doesn't work as a strategy anymore. They don't stock enough stuff anymore.
Long back story, but I recently needed an ethernet card. BB does not sell those anymore.
Also they only sell like 2 models of power supply, only about 3 models of bluetooth earpieces.
For some odd reason they have a whole aisle of dozens of external hard drive enclosures. They're identical except for styling.
They do have massive numbers of overpriced cables, but all you need on amazon is what are the connector ends and how far apart are they?
I don't even go there as a showroom anymore. Basically its a really tiny Target/Walmart without the clothes aisles. Office depot has a better selection of computer gear, which is crazy because I always think of them as "the binder store"
(Insert my standard question for all ask/. tech people)
Describe a hack that you personally participated in that you find cool. Not you paid someone to... or I once saw someone else... or you bought something cool that... I mean traditional hack like "identify problem" "flash of insight in ur brain" "minutes to days of sweat using techie tools" "something cool now exists, lookit". I don't care about the subject as long as its vaguely slashdot style technical and you think its cool and the slashdot audience would think its cool. The coolest hack is not necessarily the biggest or most famous, either. Maybe you have a hobby where you personally programmed the worlds coolest christmas light display on your house, or you handmade a truly elaborate model railroad fully articulated draw bridge, I donno, whatever floats your boat. TLDR just tell your hack story, and make it cool.
I know some white south africans who became US citizens and to answer your question, no, the politically correct class does not like them very much at all when they self-identify as afro-american. Especially WRT college admissions quotas and such. I lost track of those guys after high school but I assume they're still confusing HR personnel to this day.
The DRM one has to discount by 80% to get sales, the non-DRM one only has to discount by 50% to get sales. Interesting. That would imply DRM impairs demand, shoving the price lower by about 30%. That's a lot of profit amazon is leaving on the table apparently by demanding pointless DRM.
But for reference books, I prefer hard copies that I can browse thru at my leisure, leave open on a desk or quickly flip between sections.
open / flipping / browsing don't really do it for me. However I do "grep" them a lot. Search is the killer feature.
The problem for authors and publishers is making their reference ebook better than what you'll find via google.
I've owned and read a lot of oreilly books and they fit 4 classes: 1) anything with "cookbook" in the title = worth the money, best as a searchable ebook 2) anything with "intro" or "learning" in the title = worth the money, best either old fashioned paper or ebook only if you dual monitor or have a dedicated reader device 3) anything purely reference-ish = better off just googling for the answer for free 4) Mix of the above. Think "programming perl". Worth the money. Best off as paper copy for learning, because pure reference stuff will never be looked up, google gets searched first.
a confused student can go unnoticed in the traditional classroom if he or she doesn't give those visual queues and doesn't ask for assistance. Then the test comes by and it is too late for the student.
Isn't that a LONG TERM extremely positive outcome? Everybody's gotta learn the lesson that they're responsible to further their own education, and in the long term it seems a heck of a lot less painful to fail a high school test than to get fired from a job a decade later. Learning you'll fail unless you communicate is frankly better learned as a kid in your classroom than as an adult worker in the cube next to me, however infuriating it might be to you at that time. Technological crutch might exist in your classroom, but not in cubieland, so I'm thinking its not necessarily an advantage.
I learned enough in college to land a job as a developer and be good at it
How? I'm mostly serious AC not joking around. Show me a curriculum covering at least some systems analysis, any version control and/or other team software at all, any debugging at all, working on problems longer than 200 lines, MODERN development techniques/styles/fads, and enough business knowledge to fit in.
You may have learned that stuff on your own while attending school, but that's not an achievement of the school. I've never even heard of a school that teaches developer skills. There's thousands of higher ed schools that try to training to pound out syntactically correct code, or try to educate to become a computer scientist specializing in sort algorithms or whatever. But not dev skills.
In the 80s I watched videos delivered over cable, and they still are... Of course the deeply underlying protocols that the endusers have no interaction with have changed from FDM NTSC of educational PBS broadcasts to weird internet codecs over a docsis modem, but whatever its not like the end users will tell any difference... 75 ohm coax goes here, video comes out there...
Interactive gamification was done by my kindergarten teacher, its nothing new.
We are the first five or six chapters in a book
My experience in taking some classes is its more like the first five or six classes in a thirty two class undergrad curriculum. Everybody wants to offer freshman classes like intro to programming 101 and first semester calculus, no one wants to offer what I would actually be interested in, like upper level undergrad or grad school classes.
What, their fuel injectors? Old fashioned mechanical carburators?
Yeah I know the guy is trying to get at the wider temp fluctuations in cylinder and piston temp, unless you go uniflow which has whole nother kettle of fish, but its not really much of a problem.
See if you try to crank up the efficiency and power of a trad ICE, eventually you get all manner of predetonation (ping) and trouble keeping crankshaft loads low enough while not letting the valves float and it gets all technical very fast. With a stirling you just crank up the heat until you melt or deform the piston/cylinder. Its more easily understood so its easier to empathize so its "seems" harder, but actually ICE are way more difficult its just we can't talk in uneducated company about the actual challenges. Any moron can understand "it melted" so any moron thinks stirlings are more difficult because they can't even talk about ICE engine optimization.
I just read TFA, and what is described is in no way a combustion engine. Nothing is combusted.
They seem to carefully avoid mentioning it, but most oils when preheated to 700 degrees F (holy cow) and atomized in air will burn pretty well. Probably the water addition is to prevent the cylinder walls from melting, or more likely prevent them from looking like a well seasoned cast iron pan (which would have serious issues WRT cylinder rings)
diesel's autoignition point (not flash point, you're already mechanically atomizing the vapor) is only like 400 degrees F.
diesel has a somewhat lower autoignition point than gasoline, but gasoline has a much lower flash point than diesel, weird but true.
It's not being burned, it's only being used as a heat carrier. Seems to me it would be more efficient to just heat the water directly, and use it in a steam turbine. What am I missing here?
The hydraulics. I can't be bothered to crack open a steam table at this time of day, but a substantial sized tank of stored 500F water is going to be ridiculously thick walled and heavy... 500F oil can be more or less unpressurized.
Reading the article I'm not sure what "oil" they're using. Cheap canola oil isn't going to like 500F however asphalt isn't going to like being piped around at room temp.
The journalist articles don't detail it, but stereotypically there is a huge insulated front end tank being heated by panels so you can run the engine at midnight. Usually its a couple orders of magnitude cheaper to redesign the system to not require operation at midnight, but thats a higher level system failure.
Or has it been your experience that worthwhile PC-exclusive games are either ported to Linux
Hmm... aside from the obvious disagreement, just listing some great indie or indie-ish games: "Lunar Flight" "xplane" "pretty much everything from spiderweb software" "pretty much everything from matrixgames" none ported to linux.
The last truly multiplatform games I can think of are the infocom text adventures, which at one point in the 80s ran on pretty much anything with a screen and keyboard...
Silicon Valley imagines itself as the un-Chick-fil-A
Eve’s bared nipples failed Facebook’s decency test
LOL facebook is for middle aged women to check every 15 seconds for new pixs of their friends kids or pix of their "fur babies" aka over pampered dogs, and teenage girls to sling insults at each other and compete about friend counts. Guys mostly post "blackmail pixs" for fun of their buddies throwing up, getting high, or getting it on with a landwhale.
"tits or GTFO" is not going to work on FB. Its middle aged woman / teen girl culture not online or whatever.
Now if you posted a nice rack on a "internet culture" area like 4chan or maybe a link here on/., that would more or less work.
This is it. Sell the "watching a movie at home" or "date night" experience or whatever experience not a silvery disk.
So... stock all the stuff you need for that experience. Eighty different types of popcorn, lots of "fresh" junk food, frozen pizzas, cold soft drinks (heck, beer, if you can get a license). Also, new shrink wrapped DVDs. Nobody wants some old scratched up thing.
Another datapoint. Don't try "old" "niche" because the public library is already renting those for free. Yes, free. Sure, they're all scratchy and you're stuck with "the sound of music" but still...
I think its odd they skipped the whole audio era. You can buy a little flash drive recorder that'll record for hours right now, for practically nothing. Its hard to find a smart phone that doesn't come with an audio recorder app. Yet I never heard of the cops doing audio recording in the past. Odd. You'd think it would be almost as useful. Imagine the jury listening to the slurred speech of a suspected drunk driver at trial, etc.
Just think about it after recording grandma being stopped and searched by police randomly at the mall.
Unfortunately this is the most likely outcome. The cops where I live are legendary for pulling people over for DWB so if they're accused of harassing teenage wanna be gangbangers at the mall, that means they'll HAVE TO harass at least fifty powerwalking grannies at the mall and release the footage of the grannies to "make it fair". Its probably going to be extremely annoying for civilized people who just want to be left alone.
I think facial recognition should be applied, to some extent. Just to "get the numbers up" while guaranteeing no legal issues, I suspect a lot of evidence of non-racial profiling stop and frisk will be daily records, and an observant viewer or facial recog program will identify the officers wife as a stop and frisk "volunteer" every single day, or anti-DWB evidence will be pull overs of white people who turn out to be the officers off duty partner or relative in his personal car. Even weirdo cops don't want pointless confrontation so I suspect there will be a lot of gaming the system. Just wait for the first "profiling" lawsuit where the plaintiff runs the defense's "proof" thru a facial recognition program... it'll hit the fan I bet.
Traditionally (depends on where you live) turning on the green throws a relay shorting the filament on the opposite green. So if you try two greens at once, it blows the fuse/circuit breaker, because fuses don't like short circuits. This is tricky and your timer needs at least a fraction of a second of dead time where its red all around.
Another fun way to wire it up, is 240v with 120 lamps, hot, to green light, to the red and yellow opposite, and from either red or yellow to neutral. This makes the midnight flashing red complicated to nearly impossible to wire up. Also if you're dumb enough to mix the wiring scheme here with the scheme above, if you manage to activate both greens then you blow the yellow / red bulbs out star trek style (usually no fire, but 120 bulbs are very bright on 240 volts for a zillionth of a second...)
Usually you end up with a mix of safety designs, where some things won't power up unless activated correctly and others will blow a breaker if activated incorrectly.
Its possible to wire non-failsafe, or purely software, but usually not done.
The Russian cover didn't really help and had to be rebuilt and arguably still isn't very good. What would work is picking up the plant and moving it far inland, but that's a bit impractical. Most of the "armchair engineer" ideas are about as useful as the armchair engineer solutions for the gulf of mexico oil leak, in other words they would not work or would make the situation worse.
LOL the "one week or so" half life of I-131 explains why civil defense and.mil stockpiles only contained at most a month or two's iodine tablets to protect against thyroid cancer.... its just not a credible concern after a couple months.
Thats the cool thing about nuclear waste... 100% of the arsenic that came out of the smokestack of the coal plant "nearby" my house is still in the lake where the city gets its drinking water... oops. However virtually all the radioactive iodine the nuke plant "nearby" my house has ever made has long since decayed into irrelevance.
