oakmad··on Incident: Airbus A330 at Taipei, primary computers failed on touchdown (2020)
I wonder how much was just being « used » to auto braking assistance and what felt right.
oakmad··on Incident: Airbus A330 at Taipei, primary computers failed on touchdown (2020)
Its unfortunate they don’t calculate how big a difference it made. They’d calculated a 170ft margin and stopped with 30ft margin and I’m curious what their braking delta was for that 700ft of deterioration.

« With three FCPCs inoperative, actual remaining runway distance (30 feet margin) of the occurrence flight was shorter than the calculated value (172 feet margin), possibly due to tailwinds, runway conditions, and manual braking as these factors might increase the braking distance. »

I get sucked into how all the little things that are not right make such a big difference in these kind of scenarios.

For everyone commenting about different hardware failure modes and possible solutions. Take a look at the airbus « flight control laws » such as https://apstraining.com/wp-content/uploads/FCS-Airbus-Quick-... it governs what happens to flight controls and what protections are available in different scenarios. In this case the system worked, it crashed and reverted to direct law providing manual braking control.

Off topic but I found this very interesting « The deceleration performance of the occurrence flight between 6,600 feet and 7,300 feet from the threshold of runway 10 deteriorated. It may be due to paint marking and rubber deposit on the touchdown zone of runway 28. »

oakmad··on Ask HN: I've realized I'm a bad software engineer and I'm over 30, what's next?
> I'd been assigned a medium complexity task and I've failed to accomplish it, the code was all filled with hardcoded values, wrong structure, difficult to debug bugs and similar things.

First thing is work out to spin this properly - you're seeing this as a failure with hindsight, but why is it really like that? E.g: were the requirements firmly defined or were you trying to hit a moving target? Were you trying to appease too many owners? Were you lazy? Lack support? The most valuable thing you can provide is some objective context around why things are the way they are. Theres also different "software engineers". Maybe its the company type that you dns fit in well with? Rule number one: cut yourself some slack like you've probably given the other folk involved in the project.

oakmad··on Launch HN: Kitemaker (YC W21) – Fast alternative to Jira, built for remote teams
I know the answer is probably not, however do you have plans for things like hipaa compliance? I’m struggling to find a great IM solution that is - perhaps self hosted as others have asked?
oakmad··on Ask HN: Those who quit their jobs to travel the world, how did it go?
> Try to blend in

I agree whole heartedly. I'd gone one further and add "become a regular". Get coffee/beer/food from the same place every day and consider enrolling in a language/art/something short course. It's amazing who you can meet over the course of a month or two - I met a bunch of interesting people including my wife.

oakmad··on A Kit that converts a Classic Mini into 80kw electric Mini [pdf]
Yeah its an Australian Cooper S, I got it in 96. To be honest the tech really hasn't changed that much since. I suppose the electronic ignition is the biggest change and I changed to an HIF carb - modded to vizard spec of course. The clubman 998 I have is drum all around, and I agree! The only saving grace is due to their narrow width you can hopefully squeeze between cars waiting at the intersection when they inevitably fail.
oakmad··on A Kit that converts a Classic Mini into 80kw electric Mini [pdf]
I've got over 90hp in my modified 1275 S road engine and Swiftune can build you one around 125hp (https://swiftune.com/engine-building/competition-engines-his...). A highly modified classic mini is a visceral experience, even when operating within the speed limit and especially on 10 inch wheels. Excuse me I have to go for a drive..... I also have a clubman shell I want to do something with, vtec, motorcycle or electric? hmmmmm
oakmad··on Tinnitus Treatment from Neuromod
Interesting. I recently had mine evaluated and they suggested fractal tones (zen tones from widex). Mines stress related and I’m sure plays into my misophonia so I’m excited to learn about this treatment
oakmad··on Bit – A modernized Git CLI written in Go
You’ve never worked across time zones have you? I find it’s a lot easier to say “that commit from 2 hours ago” than do the mental math during a code review or debug session. However I do think it should be opt in as I understand your POV and in my experience it’s never an issue until it’s a big one. In our ui we show ago, local and point of origin for all time zones we deal with in a popover.

oakmad··on Show HN: Memory Pill
For added bonus: Implement a weight sensor that can detect when the contents of the bottle have changed.

I've got a patent on that - Lol. I actually cofounded a company that is in this space, Medication Adherence. Its a very curious field. Everyone says they really really care about it but its really hard to build a business around. Theres been a lot of different attempts at solving the problem but very few have gained any kind of real traction. This one is a bit like the Pillsy bottle https://www.pillsy.com, but theres plenty more of dosette like solutions (https://www.pilldrill.com) through to dispensers (https://www.lifeline.philips.com/business/medicationdispensi...). We went for a weight based solution but have largely shelved it to focus on other area.

oakmad··on Veteran submariner on how sonar crews tirelessly hunt enemies they can't see
My father used to help design and build sonar of varying types for the Australian Navy (RANRL) when I was a kid. I used to love hanging with them all and even got to go on a submarine a few times. He had to be fully qualified for sea trials. I assume a lot of his work was adapted from other countries, but he still will not really get into details about what he did for them (70s and 80s). One little nugget he told me a few years ago: their entire UI/UX team were psychologists, engineers played almost zero role in that aspect.
oakmad··on Google's ‘Project Nightingale’ Gathers Personal Health Data on Millions
Agreed. The key point I was attempting to make is that a BAA allows orgs to share data legally. AFAIK Google hasn't violated any privacy with this project and indeed they would be in violation if they did.
oakmad··on Google's ‘Project Nightingale’ Gathers Personal Health Data on Millions
Unlikely to be a HIPAA violation, pretty standard to get a BAA in place between entities sharing PHI type data. Its spelled out on those HIPAA forms you sign at the providers before they'll see you.

"The Privacy Rule allows covered providers and health plans to disclose protected health information to these “business associates” if the providers or plans obtain satisfactory assurances that the business associate will use the information only for the purposes for which it was engaged by the covered entity, will safeguard the information from misuse, and will help the covered entity comply with some of the covered entity’s duties under the Privacy Rule."

oakmad··on Google's ‘Project Nightingale’ Gathers Personal Health Data on Millions
It's an interesting issue. My start up is in the healthcare space, primarily in the USA although I'm currently based in London. Theres definitely a group here who think that NHS users just need to accept that their data is going be fed into models and its part of the price of universal coverage as it will help outcomes and costs etc. I'm still on the fence about it, but having seen some of the results that AI is catching out in the field I'm tending towards universal good over personal privacy - though I may regret that... Im thankfully that at least the data cant be used to adjust individual insurance premiums.

As an aside, it is not just Deepmind/Google, all the players are trying to get all the EHR data around the world. The NHS is particularly attractive due to the volume of historical data of course. Its no secret IBM Watson is working with NHS Wales although I don't know what data sharing agreement is in place.

oakmad··on Google's ‘Project Nightingale’ Gathers Personal Health Data on Millions
There would definitely be a BAA in place between between the providers and Google. My business has one with Google for hosting our cloud data. You know those forms you sign about HIPAA when you visit a provider? One of the things they say is the provider will only share data when a BAA is in place - well that the HIPAA rule:

"The Privacy Rule allows covered providers and health plans to disclose protected health information to these “business associates” if the providers or plans obtain satisfactory assurances that the business associate will use the information only for the purposes for which it was engaged by the covered entity, will safeguard the information from misuse, and will help the covered entity comply with some of the covered entity’s duties under the Privacy Rule."

oakmad··on Boeing Believed a 737 Max Warning Light Was Standard
Here’s an article from 1995 that talks about how 737 pilots didn’t know they had to turn off auto throttle on takeoff abort - https://www.csmonitor.com/1995/0821/21082.html

I wonder how software testing will change (if at all) in the industry post this revelation. There was an old joke during 777 development (Boeing’s first full fbw) about the difference between airbus and Boeing software testing architecture - airbus used formal techniques and Boeing put the software engineers on the first flight.

A pet peeve is people not sourcing corrections

Well there's an option for dual AOA but neither Lion or Ethiopian took it. In the case of AOA disagreement a light illuminates. Source https://twitter.com/trevorsumner/status/1106934415610073091 and https://theaircurrent.com/aviation-safety/southwest-airlines...

Except that flight was specifically to set the record for fastest London to Sydney. They waited for specific weather and carried just the crew ie no cargo or passengers. Interesting story none the less http://www.airwaysmuseum.com/Qantas%201st%20England-Aust%20n...
oakmad··on Offer HN: Advice from PhD on NLP, machine learning, and data monetization
Here is my question: http://metaoptimize.com/qa/questions/3086/what-is-the-best-w...

For MSc in Computer Science I wrote my dissertation on sentiment analysis using NLTK for my NLP needs. Although my work was nothing earth shattering, I really enjoyed it and have continued it as a side project investigating different techniques and algorithms. I'm now considering ways that I can turn this interest into my full time career (I'm a .Net developer currently). I don't particularly wish to send out a lot of unsolicited resumes and so was wondering if anyone had some advice on who best to approach? Are there any recruiters and the like that specialize in NLP?

Thanks

Adam p.s. I am an US permanent resident and an Australian Citizen, the website that has my details and some example work is www.emptyorfull.com
