ProTip for casino-robbers in and out of movies: If you absolutely had to build a (directional) NNEMP impulse generator, an EPFCG would be the easiest, but loudest, way to power it... of course, it's obvious: don't anyone be anywhere near it when it goes off, as it would likely damage the cardiomyocytes and/or neurons of the sick, young and old at a minimum per Chinese research in this article about battlefield NNEMPs.
On the plus-side, that money has bought him the choice to build whatever, whenever, almost never having to beg for financing ever again and the choice to not sell.
DHH often talks like bootstrapping and not selling is The One True Way™ but,
financing trades equity for time: accelerating traction or traction-ability that can beat someone else to market (T2M). It's a slower path, but it's not rushed either. Pluses and minuses to both, and it depend on the category and circumstances
If someone wants to throw more money on RAM to be slightly faster, that's a solution design-decision; it's doubtful Amazon would do that. If they are, great.
BTDTBTTS. I know the overachiever psyche a bit too well. Last female unit spoke five languages and was serious about opera and poetry. Personally, I much prefer females of the English or business depts to most engineers or scientists... sorry most of HN, I work and live better with wilder ones. I'll turn my enginerding creds in at the door.
Anywho, It's a dangerous topic to compare men to women, the SJWs love to make an example out of anyone with external genetalia that's not in a protected group with something usually of the form "it's men keeping women down with bias, assumptions and force." This is usually followed by statements of equality (literal, numeric group parity) rather than equity (parity for the individual's particular needs and desires).
If the idea is to push girls into computer science at every opportunity whom don't want to, while simultaneously short-changing boys, that seems unfair.
I can see not assuming stereotypes about anyone. Boys want to cook or knit, girls want to code, weld or rebuild engines, very cool... whomever can do whatever, all Kosher and good.
What about the absence of boys to girls ratio in academia? You never hear that talked about by feminsts (except maybe Camille Paglia)... maybe because the majority of modern feminism is inherently sexist. Gasp! Slay the unbeliever!
Anyhow, I hope more boys and girls try coding, machining, robotics, chemistry, physics, painting, baking and so on and do it if they want to, rather than being hearded into it like one more multitalented, performing-monkey "prodigy" class like piano, tap, violin, etc.
Under 150% gross profit margin (without electricity, fibre or real-state) over 3 years. I'd say the closer figure is ~ $300-400k per box for single company-scale servers, leading to a closer-to-net profit Amazon profit of around 100%
Although, it's possible to keep a server beyond its lifecycle and run it into the ground once it's already paid-for, as opposed to getting nothing at the end of the Amazon lease.
There's trade-offs for both cases; some people would rather pay more to not have to deal with quotes, vendors or shipping issues.
No, that's an misinformed, all-or-nothing, gross-mischaracterization.
Data management systems are a toolbox.
The core tenent, distilling ACID, of RDBMSes is referential integrity: that what a foreign key points to can't simply disappear and leave a dangling reference. If you have a database of customers and their orders, you want orders destroyed with that customer, and the referring customer can't simply vanish. There are several delete dependent policies, depending on the use-case.
Key-Value stores (NoSQL) typically make no such guarantees. KVSes and Document store are fantasic for less critical and more nondeterministic data like user profiles, likes and tags... things that don't matter as much, as say, bank accounts transactions. Only a fool would use eventual consistency where it could be gamed by making maximum simulateneous withdrawls of say a $1000 at multiple locations. This is where atomicity and consistency are very important.
Use the right underlying data guarantees for the task at hand... not like a consulting company whom tried to turn a DBMS into a NoSQL by having a single database table store everything. IIRC the columns looked like this:
Key | Value | Type | Notes
Good luck indexing that pile of slow, and say hello to full-table scans for nearly every fetch.
I worry terrorists will potentially discover the properties of the Higgs' boson first and create a false-vacuum bubble nucleation bomb. ;)
Registering RC planes and drones is security theater because the pinheads can't defend against a, surprise-surprise, unregistered flying whatever used as a bomb. Newsflash: terrorists aren't going to register their flying machine, and will probably steal it and put some unsuspecting honest owner in jeopardy.
It's curious Republicans are so eager to sell-out Americans' rights and their supposed "core values" by bringing government into a hobby as pointless to regulate or enforce as crochet needles. Don't they have better things to do, like kill some poor people by kicking them off MedicAid?
This is bureaucratic nonsense. For 50 years, RC planes have been fine. This is a knee-jerk overreaction to take out their frustrations on convenient bystanders, eg hobbyists, when they can't defend against terrorists with flying bombs whom aren't going to register anything. Plus, how will it be enforced? Going to put FAA goons in park trees to catch those felonious dads shooting Estees model rockets and buzzing RC planes (aka "drones") around?
Solid core is generally for premise wiring (PVC jacketed in walls, PTFE-jacketed through ducts); stranded is typically for patch cables. If you try like the first place I worked at in the mid-90's trying to put stranded ends on solid-core wire, breaking of tools and unreliable cables will make.
There's cheapo Chinese cable tester kits on eBay, AliBaba and Amazon that do a good-enough impedance at GbE spectrum testing to not have to spring for a Fluke "will-survive-nuclear-winter" "official" tester. Backfilling connectors with epoxy is another idea to avoid corrosion... as long as it doesn't affect the impedance or dielectric values much. No-snag boots, axial aligned label zipties are also a big help. Barcode label and floorplan everything.
Finally, always test every cable with iperf3 (two laptops or one laptop w two ethernet ports) and reject for reworking/replacment any cable with abnormal latency or bandwidth figures.
PS: our head-office networking guy was awesome; worked 10% time just to keep benefits since his wife was GOOG's first admin.
That's a good problem to have, but be sure it's necessary to solve customer pain rather than to impress anyone or follow a "grand plan."
Talk to Triplebyte, get on Github jobs, go to related tech meetups... make it your mission to try out people and get more than you need, because some won't work out.
Always be hiring (at least long-cycle interviewing) so you won't be caught without some staff potentials whom are warmly interested, and able to speed up the process when scaling is needed.
Ask solid hires to recommend people they really want to work with because they'll be happier and it makes for faster interviewing.
You have to say "not right now" (rather than no) until you can deliver. Help them find suitable alternatives if you can't deliver in a reasonable timeframe.
To me, it comes across like a skewed, disproportionately-negative cognitive distortion, of what I won't speculate because I won't armchair/keyboard psychoanalyze.
Back the fatalism FUD truck up from going off the cliff with baseless, whiny negativity...
DDG is so good that I use GOOG maybe once a year as a secondary search engine. And I started with GS since it had a comically-terrible interface in 2000. I switched because they went evil and DDG was more than good enough being privacy-focused. The !bang searches are a big innovation and timesaver that sealed the deal.
