No. You cannot get a 1TB SSD for a "decent price" in any form factor.

People seem to be forgetting that this is the consumer market where people would rather "eat dirt" so long as it's a bargain. This is the same market that favored the command line over the GUI based on cost.

Based on price, a 1TB SSD is an enthusiast item only. Even that's pushing things.

Whereas multi-TB spinning rust comes in multiple form factors that truly does qualify as "decently priced".

A mere 256G isn't even going to hold Linux + Games.

Once you start getting into AAA titles and the accumulation of same over time, 256G just isn't going to cut it for the "Windows + Games" use case.

Even phones have managed to catch up to that level of storage.

I find it amusing that someone thinks that Windows can manage with so little. With various sorts of "artistic" assets only growing larger and larger, even the rubes are likely to accumulate stuff even if they aren't trying.

That presupposes that a DOS batch file is anything like a Unix shell script. All you've really done is demonstrate how utterly clueless you are about either of the things you're whining about.

People who have no clue, should be in no position to force anyone else to "abandon the past". They simply aren't qualified to judge. This is the fundemental problem with the SystemD crowd. They are idiots distracted by shiny objects.

Lots of students struggle with math above arithmetic. They could see why arithmetic is useful, but anything above that? Not so much. So by having the students apply math concepts to accomplish something (ie programming), they'll improve in High School level maths.

Algebra is pretty much necessary, as is a basic understanding of probability/statistics. Trigonometry can be quite helpful as well. Calculus is handy to know at times, but most people get along just fine without it. Learning how to do stuff like decomposing polygons to calculate area, and deriving proofs in a basic algebra/trig course is going to give them most of the benefit of learning to think algorithmically. Any student that can't see where algebra/trig would be useful in their everyday lives has a poor teacher, because there are *tons* of examples.

What math concepts are they going to learn in a dumbed-down high school CS class that will help them enough to justify that kind of expense?

For me I would still choose a Christmas party over a SAN upgrade, as one is guaranteed to cause trouble, whereas the other is only a maybe.

I might reinforce the fact that the SAN *was failing* (often multiple times per day, causing outages of 45 minutes to an hour each time). It wasn't a matter of if it was going to die permanently, but when. Replacing the bad controller (which I ended up having to go on eBay to acquire since it was a part that had been EOL for years) was a band-aid at best, and I still had to fight to get the money for even that. Putting valuable data that has been entrusted to you at risk is not acceptable, IMO.

This sound like every business I've ever worked for.
Given the choice of doing things right and taking ages, and missing a limited window of opportunity, or going to market half-baked and winging it, and possibly making it work, I will choose the latter every time.
Every successful business does this (Apple, MS, Google etc).

Every business you've worked for engages in blatant copyright infringement and considers that okay as a normal course of business? As a side note, I left the company as part of this debacle, and they weren't able to get the feature implemented until a year and a half later.

This doesn't sound like a management problem to me. This is pure Ops.

No, it was pure management. The president wouldn't release the funds to get the necessary subassemblies built, and knew for a fact that the machine wasn't going to be even close to ready when the acceptance was scheduled. They were successfully sued for a lot of money not long afterwards as a result.

eg can you imagine if the company announced they are cancelling the annual Christmas party in order to upgrade some IT thing that no-one else knows what it does? Yeah you'd get a working SAN, but every other person in the company would probably resign. No manager will ever make that choice.

They'd understand that "no working SAN" == "no more customers", and that after the lawsuits were done there wouldn't be a company to work for.

Comment Why batteries? Hydrogen much denser. (Score 3, Insightful) 311

As I posted below, it seems pretty obvious you would use fuel cells instead of batteries for an electric aircraft... from your energy density link compressed hydrogen has an even better energy density (142 MJ/kg) than jet fuel (46 MJ/kg)!

The cost of hydrogen production is estimated to become close to gasoline production over the next decade or so, but there is a huge pollution benefit to using fuel cells which could drive adoption quicker.

The currently very low cost of oil is probably the main thing that would keep airplanes from going electric soon.

Comment Fuel cell or battery? (Score 1) 311

An electric airplane sounds like an interesting idea, especially for short hop flights...

It also seems like it would be a nice case for fuel cells because you have a much more limited need for fueling stations (basically just airports) and it would be easier to store enough energy for a moderately long flight.

Comment A better use of educational dollars (Score 1) 148

I see this big push for CS literacy in schools, and it puzzles me why we're talking about spending so much money to teach a skill that most kids aren't going to use in their everyday lives while we're dealing with stuff like the Common Core silliness and teachers/parents are having to pay for basic classroom supplies out of their own pocket. They have money to buy tablets/laptops for kids (and the associated IT support costs), but they don't seem to have the money to make sure that teachers have enough whiteboard markers, copy/printer paper, and other fundamental stuff that every school provided for the classroom 30 years ago.

IMO. time spent teaching to code would be better spent on the 3 Rs, and far more useful to the kids. Intramural programs for teaching how computers interact with and affect society might be a good thing too, but not at the expense of skills that they *need* in order to function in their adult lives.

It's easy to pick good and bad ideas after the fact. It's picking them in advance that is difficult.

Sometimes, but a little common sense goes a long way. Here are a few of the "good ideas" management has had at places I've worked that have failed spectacularly, after having had them pointed out ahead of time and been burned at the stake for it:

1.) Allowing their in-house cloud infrastructure that ran critical lockbox services for two dozen banks to run off a single homebuilt SAN with a failing RAID controller for months because they didn't want to pay for a new SAN (or even a replacement controller until the customers started talking about legal action for all the downtime), but we still had cash for a lavish two-day Christmas party.

2.) Basing a new high-profile product release around the use of a complex proprietary third-party library that they had not licensed and had no documentation for, and expecting the integration to go smoothly on target for a release six weeks later.

3.) Bringing a customer in for an on-site acceptance test, when the machine was missing a power supply and RF driver, and thus was not functional *at all*. Bonus points: the customer was from Japan and flew all the way to Florida for this acceptance test.

I get that it's hard to predict the future, and some decisions are hard to make ahead of time because there's not enough information available. That isn't what I'm talking about.

Anyone who does immediately gets the bum's rush: incompetence, insubordination, bad judgement, blamed for someone else's incompetence or malfeasance, face doesn't fit, socially inept, politically incorrect... the list goes one for ever.

It's not just big companies where this happens, and it's not limited to the C-levels and their minions. In my experience, there are far too many in management at all levels that can't deal with the blow to the ego of being told that choices that they've made aren't good ones. Rather than actually think about what they've been told, they perceive it as unwarranted personal criticism even in the face of overwhelming objective evidence.

Comment Which apps? (Score 1) 260

Browsing source on my repositories I can use Ctrl-F just fine - which other apps have you encountered that?

I have to admit I've never tried using the UI over dial-up, but that seems like a pretty niche issue for most people. You could still use a command line or other git client instead which would perform a lot better with that kind of network constraint... I totally agree with those who say the modern web has gotten too bloated but for something like BitBucket I would hate to lose some nice features the site has to accommodate those with really slow connections.

If anyone can take over the throne from GitHub, why would it not be BitBucket? They produce the excellent and free Git client Sourcetree, and all around have a more reasonable pricing model than GitHub.

It's not like I don't have a GitHub account, everyone does, but I also have a BitBucket account and have no qualms switching to them entirely if GitHub really starts being a problem (well, MORE of a problem since they did just recently have a big outage... perhaps that was early warning).

However, I'm unsure how useful it is to brick the phone rather than disable the fingerprint reader in question and force the user to enter their passcode they created

At first that seems a bit nicer for the user, but thinking longer term I think it makes a lot of sense to disable the device if it's detected it has been tampered with - I feel that's OK because of the ease of restoring the system from a backup, including the secure items in the keychain. If one bit of hardware has been compromised who knows what else was - why risk it? It just adds a lot of complexity around knowing the system is truly secure or not.
