The one in the OP has a different collector. Presumably they're sampling for explosives/radioactive matter/ ...?

Of course it would be a great way to hide something like license plate cameras, in plain sight, with the assumption that they're air-quality sampling systems.

As someone else pointed out, wouldn't these very quickly get stolen?

OT: Couldn't help but chuckle at http://www.hi-q.net/products/size-selective-particulate-samp... with the juxtaposition of the ISO9001 quality mark and the forgotten "lorem ipsum" placeholder text ...
Why not just use the database to handle the "locking" for you? For example, to ensure that an email with ID=123 gets sent only once, just check if "email 123 sent" is in the database, otherwise commit it to the database, wait for the transaction to be committed, and send the email.

Edit: Why is this downvoted? It is a serious question.
I never see anyone from Apple commenting in these threads - why not?
If you live in the US. In most countries in the EU last I checked it is far more expensive and harder to come by.
Is it? As a software engineer, I leverage those $60/month into $8000+/month.

I think that's more than worth it. Why the hell haven't I bought a backup machine yet just in case this one breaks?
Swifty Circuit Breaking
And I don't even get that much value out of my home internet access, since I'm at work the majority of the day and anything I absolutely need >50mbps for is already on my local network (Steam streaming, for example). Still, I'd feel even more ripped off paying for 50% of the speed at 80% of the price. Or 10% of the speed at 60% of the price.
There is a clear cut way - the wholesale rate. In New Zealand, an auction happens every 30 minutes where demand is tallied by the system operator (Transpower) at a Grid Extraction Point, and generators bid in what they think it's worth.

The system operator then purchases the cheapest electricity available (taking into account demand is different throughout the network, and the network can't transfer all electricity to all parts of the grid because of line constraints).

This is the cost of the 'raw materials' of the retail electricity price. A solar panel on your house really isn't any different that a little power station. You still have to transport that electricity somewhere, maintain those lines, maintain the voltage, run a power station when it gets dark, bill you, etc.

It's not a big conspiracy, it's just that the cost of energy makes up about half the costs of the electricity system. If you set at a rate higher than the wholesale rate, then there must be other reasons to do so rather than pure financials.

A good example would be if an Energy Utility wanted to attract solar customers, sell them solar systems, and put it on the bill to make them more sticky customers.

They might have said you would walk out the door, but the reality is that they would have been firing you and that would have been a whole can of worms for them.

Metal doesn't flex. Plastic does. It's not just about how it looks although they do look great.

I was still using a MacBook Pro 17 from 2011 up until a few months ago. It is still rock solid with no creaks or wear/tear.

And let me ask you do you buy a car based on how it looks ? How about clothes ?

> while Microsoft enters a quiet, user-first renaissance under new leadership

I'm not holding my breath. A lot of decisions around Windows 10 have been, in my opinion, user hostile. If Apple drops the ball, the most likely outcome is that we return to the bad old days where there's Windows - it's ugly and it sucks but everyone know how to use it - and nothing a whole lot better.
Sure, but people died in forest fires, from bee stings, mountain climbing/cross country skiing, in aircraft. It's just you're not personally sensitive to those images.
5th word in the title doesn't count as "right up front"? sigh...
I wonder if this is related to a problem hiring engineers, Apple seems to be in a full on war to employee software developers in silicon valley. They are competing with hot startups, self employment, and variety of other concerns.

Many of the issues that I'm hearing about Apples software quality appear to be caused by a company who is trying to do too much with too few engineering resources. They are getting stretched thin and having to make more quality sacrifices than their customers are willing to tolerate.

I bet that if they opened an additional engineering office in a less contentious area of the united states they would be able to staff teams more easily, with longer average tenures, and tap into the talent pool and skills that they are currently unable to hire at the volumes they require.

I would suggest Portland, Oregon as I'm a native Oregonian, and because we have some of the best software engineers in the world!
> I think that's more than worth it. Why the hell haven't I bought a backup machine yet just in case this one breaks?

Because you're leveraging credit in the event of a failure! No need to let equipment languish when you can simply pop into the store!

> The worst part of this is that Apple's success has dragged the rest of the market toward things like non-replaceable batteries

I think that statement is only half right. Apple may have pioneered the move towards non-replaceable batteries, but I think it's only a symptom of increasingly integrated and small devices. If an inch thick device is thicker by 1mm because the battery is easily detachable, that's much less of an issue than on a 10mm laptop.

They may have done it in an egregious way first (gluing/soldering in components), but we probably would have gotten there before long anyway.
What's the problem with testing, you mean? Sure, I've done plenty of testing of ES5 code without transpilers.
Google Offering 2GB of Free Drive Space If You Complete Security Checkup
I had a debate about this the other day with a friend. I am firmly of the belief the quality is bordering on poor and that if this was a decade ago, the Apple fanboys would be all over Microsoft for the same performance - remember the taunts about Windows performance and crashing from the Switch campaign?

I'm sick of constant random iOS reboots, out of date OpenGL, poor/reduced quality apps (Photos I'm looking at you), the growing monolithic nature of iTunes and the fact I feel like I'm running Windows ME all over again.

I wish they'd stop spending so much time on marketing new features -- who cares, really -- and spend a few years making stuff great.
Perhaps it's simply a jovial Star Wars reference.
I would say that some of the recent Dell, Microsoft, Asus and Razer designs are pretty nice, and there are plenty of metal laptop enclosures out there if you look.
Got any more information on that? I usually leave WMM off on account of it being extra complexity that doesn't seem to make anything work better, and I haven't noticed any particular issues with my six month old rMBP. Which chipsets are supposedly afflicted?

(side note: I wish they'd never stopped using Atheros WiFi.)
I feel as though this is comparing two different orders of magnitude. Apple users are, in general, getting upset about software user experience. A subset of users have always been upset about repairability of apple hardware, though admittedly it's gotten worse with its laptops in the past years. The subset that wants to do what we want to do with our hardware here is much smaller and thus not who Apple is trying to sell to. In the end, the users buying macbooks want lighter, thinner machines and are willing to sacrifice basically anything to get it. Personally I've given up laptops because I'm not willing to make this tradeoff, even with "pc" hardware.

Edit: There are even some people in this thread, who I assume are "power users," that are willing to sacrifice previously sacrosanct things like ethernet ports for mobility. Personally I'm not willing to do so but I also don't have a pressing need for a laptop.

I personally can't stand weed, mostly for the smell and allergic potential of public or shared-wall-dwelling smoking. At some level, it was a joy to move out of Colorado, to an "illegal" place where public and apartment smoking is much more rare.

Even to me, with this admitted bias, this article is another great argument for 50 state legalization. Chasing legal weed across state lines is a huge resource-sink which wins us exactly nothing as a society. Just get it over with and legalize it everywhere, and use the funding you saved to step up enforcement of DUI laws, substance abuse help programs, and hell, fixing bridges and laying fiber.
Sure. I've previously written up a short description of the approach here: http://andyfriesen.com/2015/06/17/testable-io-in-haskell.htm...

The general high-level approach is that your business logic functions run in some monad, constrained by the set of capabilities it requires. Each capability is represented as a typeclass.

Your type signatures say that your business actions work in every monad that supports those capabilities, so the type checker rejects any code that tries to use "unblessed" side effects.
Hehe, that's why I don't have a replacement machine yet.

Also because it has so far only died about once every two years. Every time due to human error (spilled things). I can afford a two day outage every two years :)

Don't forget about the regular Mac Pro - I recently purchased 3 of them for my design team thinking a desktop should be better than a laptop - 2 of them have had a failure, 1 requiring a replacement graphics card the other needed a system reinstall - both took a couple days to get sorted out. I doubt our next round of funding will go towards Mac products - we can buy a Dell just as powerful with same day business support for WAY less - but to tell the truth none of the Dell Precisions we have bought in the last 3 years have had any issues.
Oh, fully agreed. Have you gotten one of those ads when you don't have good network connectivity? Fails to load, fails to respond even if you go into airplane mode -- you have to wait until it can talk to Apple servers again before being able to use the app. Just happened to me yesterday.

I just bought my first iPhone (switching from an Android, the droid maxx - great battery life) largely because I missed being able to easily sync music with my phone. What do I get? Broken music player. Two of the four tabs at the bottom of the Music app are Apple Music-related (radio, "connect"). The UI for switching between displays of my library - artist, album, song - has degraded terribly. And I had to painstakingly delete all of the "cloud" versions of things I'd bought long ago from iTunes. Figured out how to only show music local to my device and now there's an annoying bar across the top of the app at all times.

I mean, fuck, how do you screw up the best mobile music player interface that hard? Just to encourage adoption of a shitty streaming service, with no way to opt out?

Do people not care about syncing music to their phone and listening to it offline anymore?
Surely you can easily find people in poor agricultural countries that do manual labour in fields for many hours everyday. How about women in paddy fields, bent over tending the rice plants for several hours each day?
I'm not sure about the battery, as it's brand new, and I don't have a need to replace it yet, but the RAM and SSD are both user replaceable on the XPS15. The battery looks like it would be a fairly easy swap as well, as long as you could source the new one.
Note that Google did a similar offer last year, but this one works even if you took advantage of that one.
I recently bought a Thinkpad to try if another platform would work. I first ran Windows 10 and found it unworkable and then installed Ubuntu, did some battery tweaking. It is great; have not touched my Mac since. Especially long battery life, swappable batteries and, for my taste, a better keyboard next to more ports is just better over all for my (full stack) dev.
You can read and write .xls files with it.
It was a while back and The Goog is not delivering, but I do distinctly remember this being an issue and that enabling this extension fixed it. But maybe only certain MBPs are affected.
Some of these headlines feel like mad libs for technology.

Occasionally it makes me feel left behind.

Then I remember most of these "new hotness" technologies get abandoned as quickly as they get adopted, so I'm not missing much.
Horrifying. Hope this is a joke.
It will become a large economy, Developed country not in the next 2 decades.
It's not really "fundamental". It's simply that the process that acquires the lock can fail (or be paused, or partitioned away from everything else, etc), and if it does, but then comes back later with a valid lock, bad things may happen.

The author's solution is to push serialization logic into the resource/storage layer (by checking fencing tokens). But what if the resource is itself distributed? Then it needs it's own synchronization mechanism? It's locks all the way down.
^ This is what I'm seeing. Sorry it took so long :(
There are plenty of serviceable laptops out there.
I love these base-level, practical advances where even a slight improvement in a formula (provided it is not closely guarded) can, say, improve the strength of a material by 5-10%, meaning that much less of it must be used, which at a scale like concrete's can make for huge changes in usage, markets, processes etc.
It's kinda weird to read commentators talking as if this was the end of a golden age of Apple.

From my perspective, their application software has always sucked. It was there because you need apps to bootstrap a platform and attract enough users to attract developers. But you can't really expect a consumer electronics company to have the best application for a given niche once the niche has been identified and attracted companies that really want to make it their bread-and-butter.

XCode and occasionally FaceTime & iMovie are the only bundled applications that I ever use on my Mac. When I get a new computer, the first things I do are usually download Chrome, MacVim, Google Photos, and VLC. I use Hangouts over iMessage, Google Calendar over the built-in calendar, and Google Docs over the office suite. On my iPhone, getting Google Maps and Yelp is a top priority, lest I end up navigating off a mountain. This is not a new habit; I've operated like this since getting a Mac in 2009 after a 10-year hiatus from Apple products.

Perhaps I was just less brainwashed than most Apple fans, and the end of the brainwashing may itself be news with big consequences for product adoption. But IMHO anyone who used the whole integrated Apple software suite and never looked elsewhere has been missing out on some seriously nice features this whole time.
I was faced with a non compete clause that would have barred me from working in the same industry for 2 years. I said I wasn't ok with. They said 'it isn't usually enforced'. I said 'then it shouldn't be in there'. I was told 'they don't usually allow any changes' (and this was a big company).

The result was that they did change it and send me a new contract.

Companies make a huge play for legal rights with contracts. Usually you have wasted a lot of time to get to that point since they haven't sent you a template in the first place. Suddenly there is an unreasonable amount that you are giving up for the privilege of working for someone. Selective enforcement is bullshit. Anything in the contract can be used as leverage against you if the company doesn't like the position they are in at any particular moment.
Did you run memtest and took a look at how the hard drive is doing with SMART Utility?
This depends on where you are. Quebec, for example, has a single standard residential apartment lease. It's written by the Régie du logement so everything in it is, by definition, enforceable.
To be fair I don't think it's fair to compare yourself to him in terms of being burned out. I'm sure he's wealthy and famous enough to get to work on whatever he wants to, whereas most people have to work for a living. I imagine if you got to program anything you wanted and only when you wanted, you wouldn't feel as burned out either.

Carmack is definitely awesome, but I really don't think his awesomeness is what stops him from getting burned out, and more importantly I seriously doubt your getting burned out implies your lack of awesomeness.
This is the excuse we've been hearing for the past 20 years. "It's not a problem with the language/paradigm, it's a problem with you/humanity".
You never want to be first in a market. You spend way too many resources educating the market, and you have no idea the size of the market. Especially if you have finite resources. Better to enter an established market with a better product.
Safari is a great example of this. Do a search for "safari is the new IE6" and there are lots of complaints about it falling behind other browsers. Off the top of my head, for example, it doesn't support the blocking of form submission with the required attribute, which makes the required attribute pretty useless and frustrates developers.
Cockroaches: Indestructible, and Instructive to Robot Makers
I am typing on a $500 Asus flip that is all aluminum with a glass touchscreen. It is very nice, but I regret the OS (Windows 8.1,locked in place using the hosts file to avoid MS upgrades).

The issue I see is that the other side of the fence is not so sweet either. You cannot release a buggy OS that leads to my laptop bricking itself 3 times, and then jump right into another one with a hyper-aggresive update cycle, and expect me to follow along. Never. I risk losing massive amounts of work and significantly impacting my revenue at the same time.

I still have not decided if I will accept the sunk cost of Apple or a user experience downgrade to Linux, but hopefully I can put the decision off for a number of years like I did migrating away from Windows XP.

The entire modern tech ecosystem is rotten:

My drivers don't work. My OS doesn't work. The official development software for my target OS stinks. The official emulator to run it is dastardly. The api and functionality of the OS itself is pathetically broken, and less productive than battling bugs in php ten years ago. It all looks pretty from top to bottom if you squint, but the emperor definitely wears no clothes. 2016 is massively frustrating, and I long for the time when the basic premise of a computer being a tool that needs to function effectively was the norm.
Which is why they lost me, and other posters in this thread as customers. Functionality >> design.

Which is a shame because OS X is a nice operating system. I would like to use it.
You can only generalize if you understand the original functionality. Multiple examples help infer this, but it this case it was initially assumed what was wanted... That's the issue. The original programmer never communicated their intention, so we have to figure out what is required from context.
The second I see iTunes is syncing I think to myself "oh fuck, oh fuck" and look to force quit the app as soon as possible.

Then I spend the next half hour looking at the connected device to ensure my collection is still there.

It's part of the reason why I switched over to the (defunct) Rdio. Managing the individual iTunes music files was just too stressful.
Shiva2012 wasn't exactly correct, there is no "clock-sync" from ground stations, each satellite has a specifically fined tune atomic clock that is designed to adjust the drift and each adjustment is unique for each satellite based on it's position in the constellation.

Some additional GR related shifts are corrected in the receivers however GR isn't the only thing that can affect the accuracy of GPS and since it's constant (although cumulative) it could be potentially corrected by other means if GR was not known at the time.

And there are of course other issues that cause errors in GPS many of them were discovered post launch and the system was fine tuned to correct for them mainly on the receiver side.
