1/ Boeing is shipping a software patch for the MCAS system implicated in the two 737 MAX crashes. Many people are calling the problem a "software bug". This is incorrect. It's a design flaw, not software flaw.
2/ I mention this because there people who want the government to regulate software bugs/vulns. They cite disasters where software is involved to justify their desire to regulate. However, much of the time, a software bug/vuln isn't at fault.
3/ Such is the case here. The software is behaving exactly as design. However, the design was to rely upon a single sensor to control the tail fins, and if that sensor was faulty, to cause the plane to dive.
4/ The same design could've been implemented as hardware circuit with no computer or software involved. It was a design decision that's at fault, not how that design was implemented.

It's important to note in this "Facebook plain-text password" story that the passwords are being stored with salted scrypt hashes, that's not the issue. Instead, the issue is inadvertent logging of web requests -- which happen to contain clear-text passwords.
2/ The analogy is that Facebook has all the proper locks on the doors -- but somebody left the window open.
3/ It's a common problem that all companies have. It should be one of the first things you audit in your security architecture. Don't simply verify passwords are hashed, also verify with the web team that they don't get logged along with all the other web input.

So I'm reading the @DevinNunes butthurt lawsuit.
BTW, calling somebody a "treasonous cowpoke" is not defamation, even if it weren't true.
I'm not sure if the @DevinCow misleads or confuses anybody into believing it's actually Devin's Cow. If you feel mislead by this, please respond to this tweet so I know that such people exist.

1/ Georgia Power (the state power company) offers a billing plan for Electric Vehicles that offers insanely low price of $0.014/kWh for off-off-peak charging from 11pm to 7am. Only it's not, that's ignoring surcharges of around $0.031/kWh
2/ So it's effectively 4.6-cents per kWh instead of the advertised 1.4-cents, which is still a good deal, just not as good a deal as advertised. For comparison, flat rate pricing is around 11-cents (combined).
3/ I mention this because of the Venezuelan power blackout, which they (probably falsely) blame on cyberattack. Our response to cyber threat to the power grid shouldn't be a secure power grid, but a decentralized one.

1of x: BEST analysis of what really is happening on the #Boeing737Max issue from my brother in law @davekammeyer, who’s a pilot, software engineer & deep thinker. Bottom line don’t blame software that’s the band aid for many other engineering and economic forces in effect.👇🎖🤔
Some people are calling the 737MAX tragedies a #software failure. Here's my response: It's not a software problem. It was an

* Economic problem that the 737 engines used too much fuel, so they decided to install more efficient engines with bigger fans and make the 737MAX.
This led to an

* Airframe problem. They wanted to use the 737 airframe for economic reasons, but needed more ground clearance with bigger engines.The 737 design can't be practically modified to have taller main landing gear. The solution was to mount them higher & more forward.

1/ Many countries have grounded their #Boeing737Max, except the #US & #Canada. @TheCurrentCBC spoke today with a former pilot, engineer, and aviation expert and litigator who said he wouldn't board a 737Max flight as he explained why this plane is not safe (transcript tomorrow).
2/ #Boeing has been working to fix problems on the 737Max by acknowledging, in corporate language, its many problems. The plane has a tendency to nose up, its softwares make the plane do things that the pilots don't want to do, and it is a new way of flying.
3/ Despite its many problems and new approach to flying, Boeing sold the plane as it would sell many others without requiring special training from airlines because training requires money and it would have turned them away from buying the plane. #Boeing737Max

Great question Wojtek and thanks for the chance to answer Sorry it'll need a (massive - take a toilet break, grab a cuppa and a comfy chair) threaded response as my tweet kept growing !! 👇👇
So #SAtSD is an attempt to create a shared collaborative approach to designing public services in Scotland. We are co-producing the approach based on collective thinking and actions across orgs and sectors that design and / or deliver public services in Scotland.
That currently includes many people and service design champions from @scotgov @DigitalOfficeLG, various parts NHS in Scotland, as well as many different public bodies, local authorities, private and third sector orgs.

So, I've waded through the Evangelical Alliance's new pastoral "guidelines" for interacting with trans people (ughh, the things I do to expose #transphobic #ciswits to the world), and let's just say it's time to tear this particular sh*t-bag a new hole.

So, straight off the bat, first page of text, the use of #language is . . . well, yeah, see for yourself:

"It is important to remember that transgender is not simply an issue to be debated;" - p5, #Transformed

*sigh*

When such language gets reinforced by insisting...

Trump Hotels' website still lists Trump SoHo New York among its properties in the Our Hotels menu. Select its name though to access its page and there's a message about it being renamed
