Ethiopian Airlines boss confirms suspect flight software was in use as Boeing 737 Max crashed

Kubla Cant

Re: Why not just disable the system and put the planes back in the air?

We know by now that the planes CAN fly without the sensor and its attempted automatic corrections -- and probably fly safer without it -- so why not disable it and get them back in the air?

I have read that there is a minimum requirement for self-stabilising flight that probably cannot be met without MCAS.

There's also the consideration that MCAS was supposed to make flying the 737 MAX just like flying its predecessors, so no training required. Disable MCAS and all the airlines incur a training requirement, which they were assured they wouldn't need. Who pays for that?

Log in with Facebook

A few years ago I worked on an application that used OAuth. The idea is that instead of doing our own authentication, we delegate it to a trustworthy organisation that maintains a huge database of credentials. It's nice because users don't have to remember lots of usernames and passwords (which possibly also makes it nice for impersonators).

One of the main authentication suppliers was... Facebook. And the ubiquitous "Log in with Facebook" on web applications suggests that Facebook's involvement in authentication hasn't diminished.

In the light of this story that looks about as sensible as letting next door's goldfish take the controls of your plane.

Boeing big cheese repeats pledge of 737 Max software updates following fatal crashes

when the Angle of Attack sensor fails, the MCAS system repeatedly adds nose down trim when not needed, until the pilots have to pull on the yokes with 50 kgs of force just to keep the nose from dropping

Re: As an aside, one thing that annoys me about my car

Not just Peugeot. The BMW 5-Series Touring (estate car) has the same stupid mistake. Also, because the front and rear wipers are on the same stalk, you have to turn off the rear wiper to wash the windscreen.

Re: Criminal Negligence and/or Corporate Malfeasance? Those are a Rock and a Hard Place

with a commercial aircraft there should be no actual reason for not giving it the best possible stability and ease of control

Apparently, the 737 was originally a smallish plane designed for regional airports. It had short landing gear so it was convenient for places without boarding ramps.

After many changes and upgrades, Boeing reached the point where they needed a model with more economical engines. But they couldn't fit new high-bypass engines under the wing. They couldn't make the landing gear taller because of the way it retracts, so the engines had to be moved forward. This pushes the nose up under maximum power. There's a suggestion that when the nose goes up the fat nacelles themselves produce lift, which pushes the nose up even more. This is the instability they were trying to disguise.

Re: Want to try to reprogram it so it feels and drives like an F1?

Off-topic, but I think the "bicycle wheels as gyroscopes" theory is mistaken*.

A cyclist essentially balances by steering the bike to keep the point(s) of support below the centre of gravity (when cornering, there are also centrifugal effects). It's harder to balance at low speeds because it takes longer for the wheels to move back underneath you. In this situation most riders also move their upper body over the point of support. The classic example of this is when standing on the pedals to climb a steep hill.

If you can't steer the bike, it's very hard to balance it. Everyone can balance with their feet off the pedals, and most people can balance with no hands on the handlebars. Both at once is usually a recipe for disaster.

* Stand your bike upside down and crank the pedals as fast as you can to get the back wheel spinning. Then tilt it. You'll get an idea how small the gyroscopic force is - especially if you have small or lightweight wheels.

Archimedes

I'm puzzled about the Archimedes screw. The picture caption says "Taking water uphill with an Archimedes screw", which is what you'd expect it to be used for. Later on the text says "When working, the screw powers the LED lights in the house's showrooms".

So it both raises water and generates power?

Re: Not sure the comparison is valid

There's a perfectly good reason for not using WhatsApp to make calls.

Last time I checked, most contracts have huge or unlimited allowance for phone calls and text messages, so using either is likely to be free. Many contracts have a fairly modest data allowance, and that's likely to be slurped by things like streaming media and transmission of images. WhatsApp activity comes out of the data allowance, so unless your phone has a WiFi connection it could end up costing you money.

Freelance devs: Oh, you wanted the app to be secure? The job spec didn't mention that

Kubla Cant

You get what you ask for

Did the requirements statement specify security? If so, what were the acceptance criteria? Were they met or not?

Any experience developer knows that exceeding requirements isn't really as good an idea as it seems. It can be the cause of confusion in acceptance testing, and subsequent arguments when your Rolls-Royce solution gets bounced back because they only wanted a VW. This is especially true when the job's being done on a tight budget - plenty of comments here point out that the rate for this job was absurdly low.

It sounds like this study was conducted by a bunch of academics with little knowledge of how software development works in the real world.

Looks like this happened to a significant proportion of ISDN users.

Is this the way the cookie wall crumbles? Dutch data watchdog says nee to take-it-or-leave-it consent

Kubla Cant

Re: Good

Unless the site has a login you are using there is NO good reason for a cookie.

You need to distinguish between persistent and temporary cookies. One of the most common uses of cookies is to preserve state between requests. Even without any login, any site that isn't just brochureware probably needs session state. It's possible to preserve state without cookies using request and response data, but this is really just a diy cookie.

When properly implemented, session cookies are harmless. Their lifetime and accessibility should both be limited to the current session.

It's curious that the proponents of meritocracy never mention its impact on the population left behind. Until the early 20th century, working-class communities might be expected to have the same distribution of ability as the population at large. When opportunities for advancement become available to the ablest, there's nobody left but those who can't get out.

There's a related problem with meeting rooms that are equipped with a screen. The hole in the table will typically sprout cables for HDMI, perhaps Displaylink, and boring old VGA. I've worked in one office where the HDMI cable terminated in a multi-ended thing that offering all the different sizes of HDMI plus DVI.

It really doesn't matter how many and how varied the connectors on offer are, because none of them was designed for a life of frequent connection and disconnection, so they don't work properly. It's possible for a while to jury-rig them by wedging a notepad under them or even getting a minion to sit holding the cable in a special position, but sooner or later they die. It's then necessary to take up the floor and replace the whole cable.

Granddaddy of the DIY repair generation John Haynes has loosened his last nut

Re: "DIY Generation"? WTF?

Agreed. I recall using a DIY manual to do extensive maintenance on a Lambretta in about 1960.

At the time I occasionally consulted a fat hardback called something like Automobile Engineering that belonged to my father. I'd guess he bought it in the early 50s, but it must have been published between the wars. It contained photographs of a very short-haired chap wearing roomy bib-and-brace overalls and an immaculate white shirt. One of the jobs he was shown doing was passing a car mudguard through a massive roller to remove a dent.

Facepalm

Re: I lost a spanner

Following the Haynes manual, I replaced the engine in a Mini. Job done, we pushed the car out of the garage, whereupon a lot of oil came out of the bottom.

What the manual understandably didn't tell you was to make sure after reassembly that you hadn't dropped a screwdriver down the back of the engine. As the car moved, the screwdriver became wedged between a CV joint and the gearbox casing. I then discovered that the back of the casing is thin alloy, concave to accommodate the CV joint with very little clearance. So now I had to take out the new engine and replace the gearbox.

Office moves

I used to work in an office that moved everyone around frequently. Nobody enjoyed it, until the time when The Most Annoying Person in the Office decided her new desk needed a thorough clean before she deigned to use it.

She grabbed a nearby aerosol can, gave the desktop a good spray, and started rubbing it with a fluffy duster. At which point she discovered that the aerosol wasn't Mr Sheen, but SprayMount*. So her dirty desk now had a nice yellow fur coat.

You like JavaScript! You really like it! Scripting lingo tops dev survey of programming languages

Re: You like JavaScript! You really like it!

Exactly.

I currently spend my days working in JavaScript, because that's what the client needs (for some reason he hired Java contractors to work on an application that's almost all front-end script). I hate it.

The popularity of single-page applications means that critical business functions are now implemented in client-side script. That's like driving at 120 mph in an old banger, worrying about whether the wheels might come off. In most languages, an experienced developer can review the code and be reasonably confident what it does, but in JavaScript there's always some nasty little surprise.
