top Taxi Medallion Prices Plummet Under Pressure From Uber
"I'm already at peace with the idea that I'm going to go bankrupt," said Larry Ionescu, who owns 98 Chicago taxi medallions. As recently as April, Boston taxi medallions were selling for $700,000. The last sale, in October, was for $561,000.
Larry believes he will go bankrupt, Larry who owns assets which he could liquidate for around $55 million - so unless he has debts of over $55 million or one CRAZY hectic lifestyle, he cannot bankrupt unless he's 2 marbles short of a jar and chooses not to liquidate now. If this is the case, then he's an idiot and I have no sympathy. And if either of the former are true, I still have no sympathy.
top In a Self-Driving Future, We May Not Even Want To Own Cars
2. Consumers want reliability and 100% availability. Consider Uber and Lyft that promise this, except during surge pricing periods. People hate this. It's economically correct in the case of Uber and Lyft, and an obvious idea, but surge pricing during rush hour isn't going to work. People will still own their own cars.
It depends on the alternatives (public transportation, flexibility of demand to go one hour earlier or later, and telecommuting etc.) but surge pricing makes a whole lot of sense. Especially when working on a scale where the surges will be known in advance, can be pre-booked etc.
It will be fine to charge 2x the "base price" for an 8.30am commute if that is what people are expecting to pay. Current hostility to surge pricing seems to be based mostly around the lack of clarity as to the actual price.
3. Personalization and customization. Hey, I like my cars stock, but I still have my stuff in the center console, my presets on the stereo (yes, 760 am in the morning, I'm a dying breed), and my iPhone paired to Sync.
This is already partially solved, Spotify will sync with your uber to play your desired party playlist on the way to the party. In the future, this kind of interoperability will become more ubiqitous.
4. Toy haulers. You're not going to call Uber or Lyft to tow your trailer to a state park or tow your boat to a launch. And this isn't 99%'er speaking, this is blue collar worker in my part of the country.
While some very specialist tasks might not be suited to a "time share" model, as the world moves to such a model it will become MUCH more economically costly to run your own vehicle - so the price point at which a specialist time-share service for minority use-cases will move down significantly.
top New Book Argues Automation Is Making Software Developers Less Capable
projects are FLOODED with automated testing tools to ensure their code works. And sure enough, every bug that I submit has an "automated test" that didn't test that particular condition
THIS THIS THIS
As a software engineer (now half-suity) of twenty years, I am constantly frustrated by those newer to the profession who got caught up in the whole "Unit Tests are Sacrosanct" philosophy. I have worked with multiple engineers who value "testability" over "working".
Unit tests are convenient, a handy tool for programmers, but in my experience they have close to zero inverse correlation with the number of bugs in the programmers output. Any programmer who can think of the right cases for his unit tests is also capable of considering those same cases when writing his code - the correlation between [Experience and Ability] and number of bugs is the biggest one out there.
Know what I favour? Readability and simplicity over pointless abstractions. Functioning, working applications over "90% code coverage". Things that fail at compile-time over things that fail at run-time. And when I press these principles onto more junior devs I always get push back about how "that's old fashioned" or "that needs extra lines of code" - they seems to complete disbelieve, and then they wonder how the hell I write and manage multiple web sites in my spare time that are generally more complex and reliable than any of the commercial sites I've worked on (with one or two notable exceptions).
KISS applies to everything, and unit tests do not adhere to this principle. They have a time and a place when they start to show their value - and that time and place is when SOME of the following are true:
-] Codebase is expected to be maintained by a large team, or eventually by persons who were not involved in building it -] Codebase will be architected by senior staff, and then maintained by more junior staff -] Codebase may be sold to, or extended by, third parties (open source is big on this) -] Codebase is difficult to read/pick-up and has high levels of abstraction -] Codebase is expected to change significantly in the short or medium term -] Team involved is junior or inexperienced in one or more significant factors (in general, language, app domain)
Outside of some of these scenarios (I may have missed some, please do comment) you should be seriously considering how much of your investment you place into Unit Tests. I have seen some companies/teams/individuals spend more time writing unit tests than they did functioning code - that's negligent in some cases. If your team had double the velocity on new features by simply writing features instead of upping levels of code coverage, your company/owners/shareholders would have twice their return on investment...
top Ask Slashdot: Choosing a Data Warehouse Server System?
We are trying to find a good data warehouse system to host and run analytics on
You're asking the wrong questions.You should start higher up the chain in business-value land - WHYdo you need a data warehouse system (to run analytics)... great WHY do you need to run analytics (to discover XXXXX from the data we generate/own/handle). OK now you're getting closer... now, armed with the knowledge about what data you will be storing, and what kind of insights you would like to generate, you need to approach a specialist data analysis & insights company who can help you to select the correct products and platforms for your data storage, processing and analysis needs.
The way you have phrased the questions in your post makes it obvious you don't really have a lot of experience in this arena, and this is not a decision you can afford to get wrong. This company may also be able to offer consultancy about generating your queries, reports, and carrying out some of the data analysis, but it sounds like you want to do this yourself - now that's actually quite reasonable to attempt in-house.

top After Dallas Ebola Diagnosis, CDC Raises Estimate of Patient's Possible Contacts
H1N1 was the flu - flu makes a lot of money through flu shots, "treatments", symptom alleviation meds. By alerting the population, the sales of related product go through the roof. How many big pharma lobbyists do you think pushed the government to scare the population as much as possible in order to drive up sales?
Ebola, on the other hand, does not have a wide array of products from big pharma that the population would be *likely* to go out and panic buy/stock up on. So no-one is telling the head honchos in government to get the bullhorn out. Consequently, no big noise...

top Your Car Will Tell You How To Hit the Next Green Light
So correct me if I'm wrong, but if all drivers adopted this, wouldn't it result in traffic in a lane approaching a light from converging together into "clumps" or "waves"?
Cars near the front of any given clump would be slowing down in order to arrive at the light after it has stopped being red and become green. (Close) Behind those cars would cars which would have passed through during the green interval regardless of this system. At the back of a clump would be cars who are speeding up to attempt to "get in" on that same green signal.
Ultimately it would result in cars travelling very close together, with huge spaces between "convoys". It might even be more efficient, so sure - but while there are still humans behind the wheel, this seems dangerous as everyone will always be "tailgating". Once CPUs are behind all the wheels, it will be trivial to implement using the "Internet of Things".

Everyone invested in Gold could decide tomorrow to shift their investments to Aluminium...or Dogecoin. This would leave Gold almost worthless. The same is true of Bitcoin - but why do you feel one is more likely than the other?

top Good Engineering Managers Just "Don't Exist"
The best engineers get all the benefits of being leaders
*All* the benefits?
I don't think so, I think it's just inertia. Our industry pays middle management comparatively poorly. In software engineering / web development which is my line of work, manager get paid barely more than senior engineers. Now I'm not one of those people who feels it's wrong to have an engineer making more than his boss (I've managed people earning more than me before, they were all awesome) but if you want the best people to step up and take a lot more pain you need to pay them a lot more.
In most other industries managers earn significantly more than their reports. Take a look at retail, at sales and many other professions. Someone in retail in the UK earning £16k/annum on a checkout line will have a manager who earns around double that - 30k or so. Same for customer services.
So, take a software engineer earning 55k/annum in London - his manager probably earns around 65k-70k, and has a MUCH more stressful and less enjoyable job, and almost certainly longer hours. His pro-rata take home is probably only around 5% better.
So how about we pay our Development Managers 100k? I bet you'd have a few more of the stronger candidates stepping up to the plate.
Yours sincerely, a (fairly, IMHO) good Development Manager in London - considering taking a step down or sideways because the money just doesn't justify the extra hassle...
