I've given up using the 3.5mm jack in situations where there might be stress on the plug (e.g. when you have your phone in your pocket). I've destroyed so many sets of headphones (or, in my case, replaced the cord on so many headphones) that it's just not worth it.

But there are situations in which I do use the 3.5mm jack, e.g. in my car.

In any case, it seems to me that co-locating the audio port with the USB port has another potential downside. If you destroy the 3.5mm headphone port you can still use and charge the phone (and use bluetooth headphones, for example). But if you destroy the USB port because your headphone cable torques in badly you have maybe 15 hours of life left in your phone before it's completely useless.

I've had the same experience. Someone listed 2 years Scala experience on a resume, but couldn't explain Unit, None, null, and Nothing to me. Or the guy this week who had several years of ops experience and when asked "how can you tell what indexes are being used in a SQL query" didn't even know about EXPLAIN.

Basic technical interviews are a must, but someone people get hung up on "they couldn't explain a hash map implementation," because sometimes "you put a thing in the map and then get it back out later" is good enough for 99% of startup engineering tasks.

Somewhere out there is a sweet middle ground, but it seems not one agrees where it really is.
> I don't really see how using an Optional type would remove the if(null) checks. It just makes the meaning explicit, which is good but not remedying the original problem.

Yeah, the benefit is not really the Option (which you still have to check), the benefit is when there's no Option. I'm not really sold on there being a benefit in Java (looks like those are the code samples in the article?), but in languages where `null` is not a part of the type, and your parameter is just a plain, `int`, say, then you know you don't need to check if it's `null`. In other languages, you either have to always check, or rely on a convention or code flow that has the null checks happening earlier.

I'm not advocating for or against jQuery or printf. I'm just pointing out that equating the two (in size, utility, or potential gains by avoiding them) doesn't make a lot of sense.

jQuery's ratio of size-versus-additional-utility is much larger than printf's, even more so if you consider typical use cases of each.

But it isn't even a fair comparison to begin with. How about comparing jQuery to libc. I'd still argue the ratio is in libc's favor, but no one would have written "I'm surprised that there's no youmightnotneedlibc.com".

Wow. A Tesla owner's complaints on the unofficial Tesla forums were reposted by an apparently-unrelated blogger who complains about Tesla a lot. Clearly this proves that the blogger "fabricated this issue" and was the one who "caused negative and incorrect news to be written about Tesla by reputable institutions" by doing so. I mean, it's not like this argument could be used to discredit any issues customers have with Tesla no matter how genuine - that'd require this anti-Tesla blogger who supposedly latches onto any perceived failure to write about them, after all.

A lot of people are saying that technical interviews are not good because some people are not good at them but they are indeed good software developers.

Other people are saying that is impossible to judge someone in a few hours of technical interviews/exercises.

I agree with both, but what's a better alternative? How to you minimise the risk of taking hiring a bad developer? At least, it is my belief that the technical interviews minimise the risk which is far better that ending up hiring someone who is not technically strong.

> And here's the problem: The DAC and amp inside that $50 pair of digital headphones are not going to be of the same quality as those in a $500 pair. Nor will the sound they output be afforded the same time and effort. Instead of trusting in your phone's DAC and amp to output decent-quality audio at decent volumes, you'll now be contending with the choices of a company that has had to cut corners to put out headphones on a tight budget.

This sounds like a good reason for the change rather than an argument against it.

Audio performance is determined by the quality of the DAC, the amp, the speakers, and the enclosure. If the DAC and amp are part of the headphones, then all factors affecting audio performance are independent of the phone. You can decide what level of audio performance you want and then buy headphones that provide that performance.

Also, many people use the same set of headphones with multiple devices. When I'm buying devices I consider how they fit in with my other devices. If I have a higher end tablet I might buy a lower end phone because many of the things I would have done on the phone had I only had a phone will be done on the tablet. Device makers tend to put the better DACs and amps in the higher end devices, and so under the current approach if I want the best audio on all my devices, all of them have to be higher end devices (and I have to get expensive headphones too).
How serious are you about finding out?

If you want to invest time into it, round robin applications. For example, if you need 3 references per application, get 4 then cycle them in sets of 3 each time. Or find an application that requires only 2 references and split sets. Eventually you will have enough data to know who the bad reference came from. This is time consuming, but will net you your answer.

The truth is, your options are drop all the references you used, even the ones you think are solid, or find out who the lame duck is and delete them.

Legally, no one can say anything because it opens them up to a lawsuit, so stop chasing that avenue unless you know them personally.

Good luck!

There are obviously long-standing cultural reasons why women and minorities are underrepresented in some fields.

Linear algebra is the sort of topic where it seems like you can always go deeper. I also got an A in my linear algebra class in college. When I got to grad school for math, I took the first year graduate course on algebra and saw linear algebra in terms of algebraic things like modules and representations. I decided that I hadn't really known linear algebra before, but that I did then. Then I took differential geometry, which involves studying infinite collections of vector spaces parameterizes by points on a manifold. I realized I still hadn't know linear algebra, but after that I certainly did. Then I took a functional analysis class, where we did infinite dimensional linear algebra, where a lot of the finite dimensional theory has analogues but everything is more complicated (e.g. instead of finite bases and dot products, you consider things like Fourier analysis and Hilbert spaces).

The same realization that I don't know linear algebra came when taking a Lie algebras class, and again when learning homological algebra, and probably a few other times as well. There are certainly lots of areas of math that I've never explored that take linear algebra in some other direction (for example, I don't have any idea what the applied math guys do with....).

It's really an amazingly vast subject, especially considering that it's usually just thought of as a tool used to study more advanced topics.
I remember from one university lan party (c. 2004) that there were 6-7 people who just wanted to play C&C:generals as well as some who would rather be playing UT2K3 but then that group overlapped with a couple of people who had insistent on turning up with linux (slackware? Gentoo?) boxes and hadn't got them fully working yet.

Then after a while a few from the 6-7 playing generals get bored, realise they don't have UT downloaded, so they head over to that guy who doesn't seem to play games but just shares files and watches movies to get the discs from him. He's happy amusing himself watching supertroopers for the 15th time and oblivious to the fact that it's 3 hours in and so far only 2 games of generals have managed to happen.

UT2K3 is huge (for the time), there's only one set of DVDs so while it's shared around the network is going slow as shit because everyone is piped into a single hub, but eventually after an hour or so the laggers manage to finish downloading and installing it.

By which time the people who started on UT2K3 are bored because they had envisaged an epic 6v6 with vehicles and instead had to settle for a fairly lame 3 man deathmatch, where one guy was so much better and couldn't help but dominate the other two.

So the linux nerds and slow installers (the games we'd be playing were published well in advance, please make sure you're bought up and fully patched) finally finish installing and then updating their installs and find that no one really wants to keep playing, but a larger game with vehicles does finally get under way.

"Starcraft is small, what about starcraft?" pipes up one unfortunate who's just suggesting that because his computer is too slow to actually run anything more modern.

It's genuinely surprising what people don't know.

"If I roll this d6, what will the average be over time?"

I've asked this to loads of supposed graduates, and apart from the odd one who made the "WTF are these monkeys hiring me for" face, a lot of people can't figure it out from first principles.

But a lot of people choke on it. Also I've had people choke on very basic general knowledge like "think of a large emerging economy in Asia".

Maybe it's nerves, maybe it's thinking too much about a simple problem.

With coding, perhaps the surprise comes from the fact that a FizzBuzz test would seem like quite a powerful test. If you can't do it, you know you can't do it. There's no doubt that you're not a programmer if you can't solve FizzBuzz and its ilk. So why do people apply, knowing they will be tested? That's the real question.

I guess the answer is you learn where you're at when someone asks you something you can't answer. Sometimes it's not where you thought.
I think people are misunderstanding this.

BBM (a consumer-level Facebook Messenger type app) is not BES (the mobile security system for corporate/government enterprises that BlackBerry theoretically does not hold keys to).

It would be like when Microsoft turns over Live Messenger and Skype IM's to law enforcement and people said "well, I guess no company will ever buy/use a Microsoft Server again". And yet, companies still buy Microsoft Servers.

That difference doesn't make this any less bad. But I wouldn't expect any major fallout from it either.
Sunlight it, if they won't change it. Bad publicity and bad behavior from other actors will only increase the likelihood that the bug gets fixed.

I've been using a SonyEricsson MW600 Bluetooth adapter for my headphones for a couple of years - it pairs with up to three devices, the audio quality is pretty good (audiophile colleagues tried it with their hideously expensive headphones and said it was "surprisingly decent"), the battery lasts me around a week depending on use, and it charges via a standard micro-USB connector.

Love it so much that when the tieclip-style clip broke, I ordered a new clip off eBay instead (Sony has a couple of successors to it, but I'll pass until this one completely dies on me).

I think this is a more interesting solution than changing physical connectors.

> Can you have a decent, up to date, programming portfolio without investing tons of time in it?

Why wouldn't you invest time in it? It's investing in yourself and could get you your next pay rise. It's not wasted time.

We're back to the point I made above about putting the effort in.

> Photography is IMO a flawed comparison since it's much easier and less time consuming to have some nice looking photos

Sure, as I already said it's not a perfect comparison, it's there to illustrate a point.

And I reject your second point very strongly. Even something simple like a single headshot can take hours of planning and setup. Something like a documentary project might take months or even years to complete.

Something like a commercial shoot might take a team of 20 a week to complete and cost hundreds of thousands of dollars - how do you get to put that sort of work in your portfolio? Sometimes you work for free, sometimes you create a whole shoot yourself at great cost. You work for it essentially. That's how.

And a single photo might be no more the 'whole' than a single file might be the 'whole' programme for instance.

Anyway, the exact vagaries of the industry aren't important, it's the assertion that programming is a creative discipline that is important.

> More than that, the photos you took in 2010 are likely to still be relevant in 2016, for the average user. However, for programming, your PHP4 project from 2010 might not cut it in 2016 when you're supposed to join a Scala project.

Possibly, but a portfolio isn't trying to sell a product it's selling 'you'. Stuff that goes in the portfolio shows how you do what you do, gives a window on how you work, how you approach a problem, how you solve it.

Many photographers will create 'behind the scenes' shoots and videos to show how they work and show clients how they solve problems for instance.

These can be independent of the exact example and just because a programming language might change you can still use an older project to show your skill and approach to a particular type of problem.

Anyway, I've laboured the point long enough, feel free to grab the last word but I think I've outlined my point well enough to be understood.
