Everyone I know uses Uber, at least once a quarter. It only takes 5 minutes for an Uber to arrive and typically it only costs $5 to get a ride back to your car, or $20 to get a ride back home. When calling a taxi, you may or may not have someone arrive within an hour, especially during peak hours. What's the point? If it takes an hour for a Taxi to arrive and you're going less than 4 miles, it's faster to just walk.
Taxi companies want the Uber business, of course they do. But Uber customers hate taxis. They're dirty, filthy, never arrive on time and dealing with change/tips is a real hassle. Especially if it's late and you've been out with friends all night. If Uber disappeared from my city I'd just stop using similar services. Uber makes it just this side of bearable. Taxis are a fucking disaster and unless I'm headed home from the airport in a foreign city, I doubt you'll ever see me in one. If Uber disappears, so does my desire to use "taxi" services.
5TB may have been a significant amount of data in 2006 for a home user, shoot I have 2TB of consumer grade camera photos floating around on my home NAS. If you're storing your steam installations on a network drive and have a dual gig-e connection to the desktop you can start running in to I/O bottlenecks loading games etc over the network with your rotational drives. Businesses already running large RAM disks for SQL are moving to SSD for a lot of their secondary needs.
I'm using Windows Hyper-V Server 2012 R2 (that's HYPER-V SERVER, not "Server", it's free) and then a bunch of command line commands. Do a google search for "ssd tiering write-back cache". Works great on my haswell era home VM lab. 6 rotational 2TB hard drives and 2x4TB hard drives + 2 64GB SSDs I got cheap from a buddy.
Technically you could do this in Windows 8 if it weren't for artificial limitations. Clever dll usage can get it to work but it's best to just use Hyper-V Server 2012 R2 which is free and supported.
Is anyone with significant amounts of data not caching their frequently accessed data on SSD? Rotational is still about 8x cheaper than SSD these days, but the days of rotational speed for cold data are numbered. Storage is easily abstracted so it's not a legacy concern. A lot of shops I know have already invested in a complete switchover to full-SSD (we're talking racks of SSD) with tape backup.
Even my home file server uses two tiny second gen 64gb SSDs for read/write caching for ~20TB of data. I just buy the cheapest, biggest rotational drive whenever I start running out of room. When the price on those new Seagate 8TB drives (currently $230) drops to under $150 I will probably start swapping out my oldest 2TB drives to avoid having to upgrade the case in this decade.
I ran five Battlefield 3 servers on two continents for a group of about 3500 registered users, and before that a Bad Company 2 server in America for a year or two. We had a Steam chat bot (IRC is Dead in this era, especially for games) that you could interact with and kick unregistered players. The first version was crude PHP run off of a godaddy account to register your account for Bad Company 2. The steam chat bot was some ruby glue code triggered by an AutoIt script/executable.
But later with Battlefield 3, we rewrote the whole system from the ground up. ChewieBot was a C# program that used an OpenSteam API dll, and called a URL via json which authenticated against another guy's custom Steam Authentication db (he handled the backend registration using the offical Steam API) and then we ran a python script from there to actually connect to the server and kick the guy(s). This actually ended up being so successful that we were blacklisted by the reddit guys on multiple occasions despite being a top 10 server. Another guy did the website redesign including custom CSS work. I didn't do very much of the coding, most of my skills were in project management and having the technical knowledge to pull together resources and people and make them work.
Over four years I worked with about 20 people in total to make the system happen and keep it running, plus bringing in regular funding to pay for the servers, mumble servers, and the actual game servers (never pay for your own servers, you're already giving them your time). All in all the project spent about $3500 in hosting, mumble server fees and the lion's share, top notch game servers (about $114/mo each) over four years.
I ended up getting the job with those project management skills I learned while putting everything together. I write a lot of server scripting/automation and also project management working with business analysts and our appdev team(s) for various internal groups' dashboards, interfaces and whatnot.
At least one other guy used the ChewieBot project to get a job as well, he added the json capability to give him a talking point in interviews. The guy who did our db back end already has a job doing C# stuff at an advertising data mining company in the UK but is pretty fantastic at what he does. With all the API hooks, free or nearly-free VPS hosting and a popular game it'snot difficult to build a reputation and portfolio (not to mention the real-world skills of dealing with true nerds) that will take you places.
The Ford Transit was designed specifically to hold two euro-size pallets. Apparently the american pallet is about 30% larger than a euro pallet, but the euro-pallet is a lot easier to get up narrow stairways common in the ultra-dense cities of europe, south america, india, china etc and the smaller size allows the vehicle to get down streets and alleyways that a standard UPS van might not be capable of.
This is an actual book, you can follow the guy's instagram or you can just buy the book. I had the 1993 edition (thanks, Scholastic Books!) in elementary school and it was basically google-lite, especially for a kid in a town of 10,000 and > bicycling distance from a major city with a Real Library (back when those mattered).
Old editions (1990's-early 2000's) of the The New York Public Library Desk Reference go for the cost of shipping.
It's a huge tome of information, roughly 8x10" pages and 500-600 pages of them, a couple inches thick. Many rainy saturdays were enlightened as a kid waiting for dilbert cartoons to load via dialup.
Most first gen 4K displays are 2x 2k displays sharing an uncut panel requiring funky software and/or driver gymnastics to get it to work well. 2nd gen 4K displays generally have the two separate display drivers condensed down to one input, but third gen 4K displays where it's a true "plug and play" single display device through-and-through are still fairly rare. This is changing though.
If you can access the data with a PIN wirelessly, why does the "owner" of the license even need direct access to it? At that point it's the issuing authority's responsibility to be able to access it using the owner's given PIN.
To condense the argument down, "why do you even need a phone app? why can't you just give your last name and PIN to the officer?" All the phone app is doing here is validating that you know the PIN.
As they're finding out, the military drones are actually better at landing themselves, instead of letting the pilots land them remotely. Under ideal conditions it's very likely that a computer will be better than humans when taking off and landing. Computers can read and process sensor data a lot more efficiently than a human's eyes and ears. We're just made out of meat, after-all.
The onboard PWM for the arduino is fantastic, but there's not enough dedicated PWM for robotics unless you're just doing a 4DOF robot arm or something, which is why I mentioned the 16 channel PWM, which allows you do do 4DOF per limb. I have the PWM shield from adafruit, just picked up their non-denominational daughterboard (same chip, more generic mounting format) for the A+ this week.
And yeah those CH340G based Arduino Nano clones you can pick up off of ebay for $4 shipped are pretty amazing, they run for over a day off of an old nokia candybar cellphone battery, I have one running an SSD1306 OLED and temp sensor that stays charged off of a tiny solar panel.
The Raspberry Pi A+ is a good Arduino competitor; I2C, SPI, PWM, the PCB is actually smaller than the Arduino Uno R3 (standard Arduino footprint), and uses 100mA at idle (compare to 35mA at idle for the Arduino idling in non-sleep mode).
I haven't measured the A+ with the HDMI port turned off but at 100mA it's very competitive powerwise and runs a full linux stack, but has enough horsepower to do computing like OpenCV, encrypted wifi, and has full access to mathmatica and it's API now for highly optimized computing tasks, making it ideal for a robotics project. The Native PWM isn't so great but with I2C you can talk to a 16 channel PWM daughterboard for about $15 more.
Oh, and it's about half the weight of a BeagleBone Black, even if it's less powerful.
Yeah 800w in that case is peak. If you're not home during the day and it's cloudy, that's still 200w going in to your batteries for use when you get home. If it's raining and you're home on a Saturday playing video games with the electric heater on at 9am, it's likely you're draining your batteries much faster than solar is feeding them. It really depends on your residential use scale. As a bachelor I don't have daytime power needs, but a stay at home mom or elderly retired may have a constraint drain.
Germany is cloudier than Seattle and yet they're the global leader in solar power. Go figure.
Have you looked at the price of Solar these days? In bulk it's down to less than $2/watt and that includes the inverter. You can install 800w of capacity for $1200 these days (plus batteries) so you're looking at $3000-4000 for 1KW professionally installed with lead acid battery backup. I pay about $1500-1800 a year for electricity in Texas and that would cover about 70% of my peak usage and would pay for itself after the third year. Solar is good for about 18-20 years and drops below 80% of it's nameplate rating after about 25 years. After year 5 you can just take your savings and roll it in to buying additional capacity/maintenance.
Anyone have a suggestion of a dropbox/owncloud replacement that is NOT written in PHP? PHP projects tend to be "babby's first project" and riddled with issues, security holes etc. Owncloud has been out for a few years but I'd like to avoid PHP if at all possible in the age of Ruby, Python, etc.
The motherboard is a one piece unit with soldered on eMMC, RAM, CPU etc, battery is glued in, etc. Basically you have a plastic clamshell around the display, and a plastic clamshell around the keyboard/motherboard, and battery glued to the clamshell.
They're drop shipped directly from the manufacturer to the school district. Same as how enterprise computer sales work. There is no big box "chromebooks for schools!" retail outlet that superintendents and CIOs drive to once a year with their SUV to stock up on the latest school technology, and then drive home with it to wrap it up in christmas paper.
Generally when I come across cursive I just look for the d, b, p, g, t, y, i and j's (the letters with limbs or dots) and then piece together the word from the visual pattern they create. I'm pretty sure that's how your brain parses printed text as well.
We were the last class in our elementary school to learn it... in 1989 or 1990. This was up in washington, we were still playing Reader Rabbit on an Apple II that the 2nd grade classes all shared.

The Constitution is some illegible form of cursive and my signature these days on credit card receipts is an "X" to save time.
The rocket motor on the Zvezda module has only fired twice, the second time happening 7 years after the first time. Resupply ships dock with the ISS and just before they leave, they boost the orbit until they have just enough fuel left to deorbit. Since the ISS' orbit degrades approx 1-2 km/month they boost it anywhere from 50-100km using resupply ships. The ATV has boosted the ISS numerous times.

I think the first quote is attributed to Jeremy Clarkson (of Top Gear) but otherwise is an acceptable opinion on the subject.
