TEA/TEB (Triethylaluminium /Triethylborane) aren't hypergolic - they're stored mixed in a single container. They're pyrophoric, which means they burn on contact with oxygen or any other oxidiser. TEA is so reactive

Not really, more like finding both in the same book store. Different audiences like different formats, so if you can have both you get more viewers. Personally I hate the narrative form of news reporting, I like just the facts.

It's also the reason for Night Glider Mode: https://en.wikipedia.org/wiki/Night_Glider_mode Laying the panels 'flat' with regards to the orbit saves significant amounts of fuel. There's also a mode

Vibrations are a constant worry for the ISS. The structure is pretty stiff - each module is connected with a series of bolts (20 I think) and very stiff steel rings. One of the long term fatigue problems they have to worry about is the impa

They are rigid solar panels mounted on Kapton tape. There's a fan-fold mechanism to store them for transport - exactly like old tractor-feed printer paper. They can fold them back up, and they are an in-space replaceable component but

As a professional software engineer I can confirm that many of our rank have some sort of blind spot when it comes to error messages. Many time someone has commented "I don't know why this build is failing!", and a quick sear

yeah, I was disappointed. I would consider a full recreation (with adapters for output etc), but even then we have plenty of emulators. The keyboard itself was cheap and bad.

Here in New Zealand all goods sold to a consumer have to have a 'reasonable' life-span, with repair or replacement at the merchant's expense. Reasonable depends on the appliance and is determined by a magistrate. Things like

Where I work we have the same problem with MSSQL. Unfortunately the dataset I work with is not very consistent, leading to the main key not being very useful to the query planner. I'm sure Postgres would have similar problems on the da

I think the key thing here is Google "following". Google have their own fork of WebKit, they can implement pointer events if they so choose, and they also have a far, far larger share of the desktop browser market. Except for on m

CPython is actually hybrid reference counted and garbage collected. This is really an implementation detail for historical reasons, no other Python implementation I'm aware of uses reference counting. There is no Visual Basic 7. Visual

I've been learning Haskell off and on for the last five years, and despite the steep learning curve for an imperative programmer it's well worth it. Once you grasp the idea of what not how, and embrace type inference it just gets

Definitely true. Plus there's a long standing precedent that save files aren't copyrightable, since they aren't a derivative work.

Authentication for Github Enterprise is customisable. At my organisation we use LDAP, but it has built-in auth and a few others IIRC. The enterprise product is stand-alone, it doesn't talk to the cloud version.

You'd need to reverse-engineer the PS4 libraries. I have no idea what libraries Sony provide for the PS4, but I'd assume the UI, audio and graphics libraries are all custom. There's also probably some sort of DRM library requ

I got an iPad soon after they were released. I never really used it much, and for a few years I pretty much ignored the tablet scene. Then I took a long overseas holiday. It was great having something bigger than my phone, but easier to tra

Wine on OS X has been stable enough for gaming for years! Sims 3 used it, as does EVE Online, and quite a few other major titles, mostly those from EA. They all use TransGaming's Cider fork though, I'm not sure if TransGaming ever

The difference is significant, but if you need two resistors it's $0.50 each, or a bag of 100 from the internet for $5 + shipping + waiting, then having 98 left over. Unless it's a particularly common part you'll never use th

None of the examples you've cited are software bugs, all physical failures or pilot error. If you're looking for something that could be software related try Air France Flight 447, though even that is ultimately pilot error. You c

I guess the idea is the old "Only criminals use encryption, so you must be a criminal". Of course, given that the big crime networks are sophisticated this won't stop them. They'll go back to old cyphers and steganograph

That doesn't sit well with Postgres' MVCC system, since between updates and VACUUMs you'd either need a secondary heap or the heap would need row-adjacent space reserved for the updates. FWIW MS SQL Server has this problem wi

Here in New Zealand over 60% of retail payments are done using cards, especially as the local EFTPOS system is very low fee compared to credit card. I can't recall the last time I had to use cash. There's still a few small cash-on

Well, guns - especially handguns and military-style assault rifles as opposed to hunting rifles - are designed and built to kill. If you only have a gun for personal defence its only purpose is to kill a human. Non-automatic rifles and shot

Don't know about Norway, but here in New Zealand there is a personal income tax with progressive rates from 17.5% to 33%, with an additional ~1.5% ACC levy (essentially accident insurance). There's also 15% flat-rate GST (a value-

As a software developer and ex-linux user (it's still crap on the desktop) it's quite clear Apple have segmented their user base. Out of the box it's quite simple, but get a (free) developer account and install Xcode and you
