In my day we didn't have the internet and we learned by writing code and looking up function calls in books and bugging the guy at the computer store.

With all of the free learning materials online you can literally get a university education from top schools for free.

If I was starting out now I would considered it because it's a fast track to employment. When I started out I knew how to program but no one would consider you without an education. That forced me to go to college and learn fun things like COBOL and jcl and many other languages in a short period of time. In the end I rarely use most of those language but if a mainframe opportunity comes up I'm ready. Being forced to learn so many things at once was the real education because it helps in the real world where you are expected to pickup new languages. For some reason my mainframe dev resume bullet points have never been mentioned during an interview. If you can develop for a s/390 that should somehow give you a slight boost for your next javascript role in my opinion.
Original HN thread https://news.ycombinator.com/item?id=13917778
Understanding a UASF requires understanding where hashrate comes from. Bitcoin is very clever in that hashrate costs money, and not just a little money, it costs a lot of money.

Which chain has more work is approximately saying 'which chain destroyed the most value in electricity'. The proof of work powering bitcoin costs hundreds of millions of dollars per year.

Nobody burns hundreds of millions per year for free. They do it because you receive Bitcoins as payment, and then you can go sell those Bitcoins to pay your electricity and hardware bills.

That means you have to be able to find someone willing to buy them. A UASF is a bunch of users saying 'we'll never buy your coins unless you follow our fork'. If only a few users say this, it's no big deal, and the miners can decide to listen to them, or they can decide not to bother.

But if 2/3rds of the userbase all agree to enforce the UASF, the miners suddenly are going to have a lot of trouble selling their non-UASF coins. Enough trouble that they probably can't pay their electricity bills. Even worse for the miners, the UASF chain has a high block reward, so they know that if they do mine the UASF chain, they actually will be able to pay their bills. And if a competing miner does it, that competing miner will have much higher margins, higher profits, and will be able to out-invest you when it comes to buying more hashrate.

Scariest of all, if the UASF chain ends up with more work than the non-UASF chain, the non-UASF chain gets completely obliterated, and its full transaction history is reversed, and all the blocks you mined as a miner are destroyed. So even if the UASF doesn't seem to have majority support, it's really bad for you as a miner and as a user if it ever eventually does gain majority support. So when the UASF has a lot of traction, really the safest move is to join the UASF, because at least then your coins aren't at risk of being eliminated entirely.

Operating systems were written in high(er) level languages a number of years before C, or UNIX, were invented.
My experience has been mostly different. I recently broke something on my gas stove (by being an idiot) that made the two front burners unusable. I looked for replacement parts online and turned up nothing, so I called a repair shop and was told that the broken part isn't and never has been made available by the manufacturer. So I'm totally out of luck on that. On the plus side, the stove was made in 1994 so it worked pretty well for over twenty years.

On iOS you have to go through the extra step of getting the binary onto a jail broken phone to strip the drm in order to re-sign it. Once you've got a way tamper with the binary and run it, most platforms are pretty straightforward to work with - it's really just down to which byte code or assembler variants you're most comfortable working with. Obfuscated code isn't a barrier. Obfuscated control flow is more irritating, but I don't think the standard Android tools offer that?
The new A8 looks quite a bit like the new Lincoln Continental. If you integrated the door handles on the A8 with the window trim, it'd be hard to distinguish between the two cars from an appreciable distance - at least the rear, profile, and 3/4 views. The rear light arrangement, the integrated dual exhaust ports, the silver trim character lines, even the A/B/C columns.

Ah, I had larger than average/sudden blood loss in mind. My bad.

I'm not a biochemist, but my understanding was that the natural, far slower rate at which blood is broken down / discarded is much less conducive to having a good supply of healthy Erythrocytes than what you get when half a litre of blood must be replenished. Upon doing a donation that's a solid supply of fresh red blood cells into your system.

I was referring to it specifically being beneficial to men because they/we do not have menstrual cycle - where blood is refreshed at a higher than average rate as such.

Also. In case of a trauma, it would stand to certain reason that someone who is a regular donor would be better equipped to recover from this than someone who's never experienced blood loss before.

I have always wanted a rich text editor where you could see the markdown as well as the formatting it produces at the same time (and in the same edit pane... ie not realtime rendering in a pane above).

That is if you typed:

It would show blah and still show the asterisk but in bold (apologies for using code format but HN will strip the asterisks).

There are of course some editor plugins, and IDEs that do this but I haven't seen one on the web.

EDIT Oh apparently there is stackedit (I hadn't googled in awhile).

Sure, lets just start with the positive vibes, overlook the potential ramifications for the creation of a real vampire-class of humanity, and just enjoy the fact that the old can exploit the young and become strong again.

I mean, the Nazi's and Imperial Japanese did a lot of positive things for human sciences .. can't we just enjoy the fact that their research into the limits of human endurance has made it possible to be a better military pilot? C'mon people ..

Uber never dominated in Russia.

I talked to Moscow taxi drivers on more than one occassion and they were dismissive of Uber as an older and inferior iteration of what Yandex.Taxi was doing. Uber was never at the top, but at a fairly distant second, so their minority-shareholder "merge" with YT is of no surprise.
As a hiring manager who reviewed many bootcamps and interviewed bootcamp grads, DBC was top tier. I hired a few DBC graduates. The people who went through their program tended to be extremely smart and motivated. The program itself was very thorough and demanding.

> I don't understand how can any other group of people decide what should happen other than the miners.

You are missing one of the key economic components of Bitcoin. Mining costs a lot of money. Nobody mines for free or at a loss, because 'at a loss' means to the tune of hundreds of millions of dollars.

Miners unquestionably mine the chain that has the highest block reward. Historically, hashrate has always been a function of $hardware_efficiency * $block_reward. If the block reward goes down, hashrate goes down (except where hardware efficiency is increasing fast enough to compensate). This is a lot more visible in the altcoin world, where miners can easily jump from coin to coin, and do as the coins fluctuate in value.

So what determines the price of the coin? Well, supply and demand. If people don't like your fork, there will be low demand, and your fork will have a low coin price. This will result in low hashrate, because miners aren't going to be willing (or even capable) of mining your fork at a loss.

Consensus ends up being fundamentally driven by the economics, and the economics follow the userbase.

Good point, but then again how this complex routing will be implemented in practice remains a bit foggy and highly experimental: http://bitfury.com/content/5-white-papers-research/whitepape...

And while this is an important feature of lighting, it's not actually a "feature" when compared to Visa or MasterCard and the centralized banking system from the point of view of the user. Ideally this should all be hidden away from the average customer.

People won't want to worry about graph theory when paying for a sandwich at a gas station. Existing payment solutions still wins hands down 99% of the time when it comes to convenience even if we imagine a "perfect" lightning network. I really have a hard time imagining what would drive a mainstream adoption of bitcoin over the current status-quo.

It's colossal because of the sliding difficulty. The block period is a big portion of why the transaction rate is what it is.

"Uber will invest $225 million and take a 36.6 percent stake ... Yandex will invest $100 million and own 59.3 percent"

Bitcoin may not scale well, but it is the capacity problems that lead to high fees. These are two different things and it is important to not conflate the two.

Scalability has improved somewhat during the past two years and most developers believe it is time to increase capacity as well. The question you refer to is how to increase capacity, within the scaling constraints.

I understand the ambition to be neutral in a contentious issue but one must be careful as not to spread misinformation. "Discarding less useful data" is not how segwit works at all. Segwit does away with the fixed blocksize and uses instead a flexible block size of up to four times the previous fixed limit.

The discarding you refer to is the backwards compatible aspect of segwit where it can communicate with older nodes that do not implement this feature by not sending them the data. It is not discarded and a supermajority of the network must use the full larger blocks in order for this to be secure. It is merely a transition method to allow for upgraded and non-upgraded nodes to briefly share the same network.

So what you refer to are two methods for larger blocks. One must be upgraded with a flag day where everyone upgrades or you lose money, and one allows for a transition with a certain amount of backwards compatibility.

It is also misleading to describe this as two "sides". The sides are mostly within social media. The technical debate has been had and there was overwhelming consensus among the developers that the backwards compatible way should be deployed first.

If the technology takes off and solutions such as Lightning prove viable, most developers agree that the non-witness part of the blocks probably needs to be upgraded as well.

Cost of university education has risen much faster than inflation for decades primarily due to easily obtained loans and increasing bureaucratic overhead. At the same time, the job prospects for many degree-holders have decreased. Additionally, student loans are for life and can not be cancelled by filing bankruptcy now. The 20 year thing mentioned by the above comment only applies to very specific government jobs.

So education is more expensive, student loans are more expensive, student loans can't be cancelled, and job prospects and real income are worse.

The United flight wasn't even overbooked either, all paying passengers had a seat. They booted paying passengers for crew members.

IMO the correct thing to do is do everything they can do to find alternative arrangements for crew member transportation in that case. I think paying customers should be the priority.

Another mistake made was allowing the passenger to board and then removing him. Bumped passengers should not be allowed to board in the first place.

I don't go to Disney parks very often but the "expanded ride reservation system" mentioned in this article has actually gone from good to terrible, and I think it has contributed to longer waits.

The old Fastpass system required you to go visit a kiosk near the ride itself, and acquire a ticket for a specific time window later in the day, at which point you could go in via a shorter priority line. It worked great and was actually kind of fun.

I understand they would want to get rid of the physical passes the machine printed out as the machines were probably maintenance nightmares, but they did more than that. They changed the system entirely to an app, which is fine in itself, but they eliminated the need to visit the ride area to get the pass, which is part of what made the system fair. Instead, you can schedule the passes ahead of time, even for future days, and of course passholders and people staying at the park get priority, so all the popular rides' Fastpasses are already gone by the time the typical visitor is even able to attempt to schedule anything, which means they will just have to wait in the regular long line because there's no way smooth out the demand across the day anymore, since all the scheduling happens for a select group ahead of time without requiring any physical commitment.

In short, they sabotaged themselves, at least from this visitor's POV. Fastpass was one of my favorite bits of visiting Disney parks, but the new system is one of my LEAST favorite bits. Ah well.
I hope we get this sooner than the privately-owned self-driving cars. So long as folks can buy monthly passes (or give poor folks the passes at free and/or reduced rates), I think this has the potential to greatly improve lives.
