GiuseppaAcciaio··on OpenRAMAN – Low-cost, high-performance, open-source Raman spectrometer
I used one extensively to map residual stresses in sintered ceramics
GiuseppaAcciaio··on Blameless post-mortems and a just culture (2012)
Assuming that "bad developers" is indeed the root cause, that still sounds like a systemic issue to me:

a) are the developers bad because they were hired that way? maybe the hiring process is broken

b) are the developers bad because they are not managed/trained properly? maybe managers aren't doing their job, and maybe it's not even their fault because they did not get training in how to manage people in the first place

c) if you implement extra layers (or "synergy coordinators") it probably means that the company hasn't figured out how to communicate properly

GiuseppaAcciaio··on Alcoholics Anonymous vs. other approaches: the evidence is now in
Not the person you were replying to, however for me it mainly helped me understand that my loved ones' drinking was not something I could control, and it allowed me to let go of the anger and resentment (easier said than done).
GiuseppaAcciaio··on Alcoholics Anonymous vs. other approaches: the evidence is now in
Same here, been to Al-Anon meetings in London UK, all hosted in church basements and with zero religious nonsense being spouted... just the Serenity Prayer and tbh that one is just plain good advice so I did not mind :) I have nothing but praise for the 12-step system as I experienced it
GiuseppaAcciaio··on Ask HN: What are good distance learning Bachelor's/Master's degrees one can do?
I would avoid anything provided by Laureate Online, I have an MSc from the University of Liverpool that was provided by them and although the degree was legitimate, the quality of the "tuition" and course material was very low; ultimately I still got some value out of doing the coursework and dissertation but definitely not good value for money IMO.
GiuseppaAcciaio··on Cosmoteer: A starship design, simulation, and battle game
Why not make it Early Access (if you're actually planning on releasing a fully fleshed out singleplayer campaign), brand it as a sandbox game and be clear about what's working and what's not yet implemented? I would buy this game based just on the info you put on the website :)
GiuseppaAcciaio··on Boeing’s Homicides Will Give Way to Safety Reforms if Flyers Organize
It's an interesting conundrum, because ultimately the FAA doesn't have more engineering expertise than Boeing so all they can do is force Boeing to prove that they have done their due diligence in confirming that the 737MAX can be operated under the same type rating as the 737NG.

I'm guessing the next step for FAA and EASA will be to revise the process under which this approval was granted to Boeing.

GiuseppaAcciaio··on Boeing’s Homicides Will Give Way to Safety Reforms if Flyers Organize
Taking your argument a bit farther: let's assume that indeed the only issue present is a faulty MCAS implementation and that gets fixed. If the aircraft comes with additional training and certification requirements for pilots before it can be safely operated, then arguably it cannot be lumped into the same type rating as the 737NG.

This would destroy the main selling point for Boeing (training pilots for a different type rating is a massive expense and headache for airlines), and would also mean that across the world there would be no pilots allowed to fly the existing 737MAX.

The point about not cancelling the 737MAX because of the risk that the new models developed would be rushed and unsafe due to Boeing rushing the development of a new design is... not very plausible I'm afraid.

GiuseppaAcciaio··on Boeing’s Homicides Will Give Way to Safety Reforms if Flyers Organize
No it didn't, you uninformed person. The two companies are in talks about a joint venture, but it's not yet ratified because the antitrust authorities in several countries haven't finished their due diligence yet.
GiuseppaAcciaio··on If Dwarf Fortress sells millions on Steam, its creators will give the money away
I'm just glad that Tarn is finally looking concerned about his own health, considering he has (according to interviews) been living like a hermit and subsisting on red bull and soft drinks...
GiuseppaAcciaio··on Weekend ‘catch-up sleep’ is a lie
Yes they are (2x as much as me), and no you don't.
GiuseppaAcciaio··on Weekend ‘catch-up sleep’ is a lie
I'm afraid that this suggestion is a bit glib and simplistic: there are people (my S.O. being one of them) who despite no alcohol, no artificial light after dinner and all doing "all the right things" still can't fall asleep before 2-3am, which then leads to 4- or 5-hour nights all week long. For them, catching up on the weekend is the only solution (albeit an imperfect one).
GiuseppaAcciaio··on Facebook won’t let you opt out of its phone number ‘look up’ setting
I read the first and while the ideas explored were interesting, I found the writing itself to be completely off-putting:

- first of all, Three Body seems like the most boring videogame ever developed, not sure how people could actually be believably playing that.

- the characters are pretty much caricatures of stereotypes (the cop), or just plain uninteresting.

- the massive exposure/infodump chapters killed the immersion from me, especially the ones written from the point of view of the other side of the conflict: it really felt like the author was getting towards the end and wanted to Explain All The Things, but couldn't find a subtle way to do so within the narrative, therefore decided to just vomit it all in a single spurt.

I was really looking forward to it but found it disappointing, won't read any more from this author.

GiuseppaAcciaio··on Dear Tumblr: Banning “Adult Content” Will Harm Sex-Positive Communities
I don't believe in good faith arguments when it comes to services operated by big corporations: regardless of the good intentions of the humans originally involved, the corporate machine at some point takes over, and rules are enforced in such a way as to maximise share/stakeholder value and/or to minimize their risk.

If something is not explicitly allowed under the rules, I wouldn't trust that it's going to be allowed by some discerning human of goodwill.

GiuseppaAcciaio··on Measuring the “Filter Bubble”: How Google is influencing what you click
I keep on trying to love duckduckgo but find that often even typing the exact title of an article I'm looking for, it's not on the first page of results...
GiuseppaAcciaio··on The greatest sales deck I've ever seen (2016)
It really depends on the organization: the Holy Grail is to have a well developed Sales Support function that prepares decks for sales people from a data source which is pre-approved (some investment banks have that, it's awesome) so that the Sales people can focus 100% on doing their thing.

In smaller, scrappier companies or just in less "sexy" industries, sales people are known to prepare their own decks and whether prior approval is sought is really to the mercy of the individual's integrity and savvy.

GiuseppaAcciaio··on The greatest sales deck I've ever seen (2016)
I wouldn't think this as an "either / or" approach: in my experience, a sales pitch and a deck are very rarely the deciding factor in closing a sale, however they can help tremendously.

The key aspect here is that a pitch like the one described is usually made to very senior people in an organization, who have little time and mental bandwidth to endure through a list of facts and figures and shudder product features: getting them invested in the result that would come from adopting the product/service is the ultimate goal, not closing the sale at that stage. You still need to do all of the good (i.e. fact-based) salesman work, but that is done at a different time: either ahead of the executive presentation (in which if you did things right you may have the buyer on your side in making a case for using your product/service), or as a consequence of it.

To me what's interesting is not the deck itself, but the focus shown by the company on sticking to their marketing points and on enabling their salespeople to do their job more effectively (you have no idea how many times I have had to figure out on my own what to answer to a prospect that was asking "what makes your company/product/service different from any of your competitors?"...).

GiuseppaAcciaio··on Amazon admits it exposed customer email addresses, but refuses to give details
Do a bit more research: you'll find that Troy (the guy who runs the service) has been working on this for several years before any involvement with 1password, and so far he's been very transparent about what he does with breach data and also about his relationship with 1password. Whenever he gets access to an unverified dump he first tries to verify its authenticity with the company or service that was pwned, then gets in touch with people whose details are in the dump to verify if the data is real.
GiuseppaAcciaio··on Amazon admits it exposed customer email addresses, but refuses to give details
Because Amazon leaking your email address means you are registered on Amazon; there is a high likelihood that you actually purchased stuff there, and therefore they have your address on file, and maybe even your credit card.

Since a lot of people re-use passwords, if your email is also contained in one of the countless breaches that we've seen cropping out in the last few years, there's a good chance that your Amazon account is using one of the pwned passwords: therefore Amazon's statement that people should not change their Amazon password is potentially harmful advice.

GiuseppaAcciaio··on How the World's Most Difficult Bouldering Problems Get Made (2015)
I'd definitely enjoy cycling more if I didn't live in central London, which makes it more of a "death wish experience with lungfuls of toxic shit" than I'd like :)
GiuseppaAcciaio··on How the World's Most Difficult Bouldering Problems Get Made (2015)
Bouldering is the ultimate exercise form for me: it's physically taxing, and I don't even care because my brain is enjoying the challenge too much! I can't commit to running, cycling or swimming because 30s in, I start to think about all the stuff I could be doing instead; when I'm bouldering, there's nothing else in my mind except for the problem :)
GiuseppaAcciaio··on How the World's Most Difficult Bouldering Problems Get Made (2015)
I'm tall and lean-ish, and my nemesis are those problems where you are compressed in a tight package... Depending on the climber's own physique and technique, the same problem can often be attacked in completely different ways.
GiuseppaAcciaio··on Chart of the Decade: Why You Shouldn’t Trust Every Scientific Study You See
^ this. Especially on highly sensitive topics like medicine, I tend to be cautious when reading about the findings of any single study; whenever someone tells me "there's a study that says [flavour of the day]" my immediate reaction is to go see if there's a Cochrane meta-analysis :)
GiuseppaAcciaio··on Operation Luigi: How I hacked my friend without her noticing (2017)
I guess the threshold isn't the same for all of us, I didn't get irked by he jokes at all... however around halfway through I started wishing for it to be over soon(tm)
GiuseppaAcciaio··on Dissecting the Bloodthirsty Bliss of Death Metal
eh, the guy is trying to do science so it's not a question of agreeing or disagreeing with a hypothesis, just whether representative data can be collected to validate (to a certain degree) or disprove the hypothesis.
GiuseppaAcciaio··on Dissecting the Bloodthirsty Bliss of Death Metal
Let me rephrase and see if I can get my meaning across: the author is asking if there is a pre-existing genetic/morphologic/physiologic/whatever predisposition that makes it so that some people can listen to death metal and suchlike and have a positive reaction where others (anecdotally, the majority of other people) will have a strong, visceral negative reaction.

Is there a biological cause? Is it a "learned" like/dislike?

GiuseppaAcciaio··on Dissecting the Bloodthirsty Bliss of Death Metal
It's still worth a read, and as well a summary article/comment written by the author (https://www.researchgate.net/publication/324102543_On_the_en... , pdf available).

The study is not without its limitations (self-reporting is the major one), however it's an interesting topic: the author's main hypotheses are:

a) there's something with the way death metal/violent music fans' brain is wired that makes it react positively, whereas with non-fans it makes them react negatively.

b) people who enjoy Death Metal do it by distancing themselves from the actual lyrical content ("it's just a song") and use it as a pressure relief valve of sorts

c) people who enjoy Death Metal enjoy the feeling of being in an elite club that's set apart from the faceless conformist masses.

It's bloody hard to set up experimental protocols to find reliable data to support or go against the hypothesis, but I'm going to keep an eye on this Thomson guy, and of course I'll keep on enjoying my violent music :)

GiuseppaAcciaio··on Lion Air crash: Boeing 737 plane crashes in sea off Jakarta
Sounds like Boeing all right (source: I work at an MRO and deal with them regularly). They don't do nice and fuzzy but they will get to the bottom of the technical aspect of the investigation. Out of cynicism, however, I'll keep my eyes peeled for "free upgrade" Service Bulletins and configuration options being offered to new customers in the near future (like they did with the Short Field Performance on 737NG).
GiuseppaAcciaio··on Ditching Windows: 2 Weeks with Ubuntu Linux on the Dell XPS 13
I remember when I installed Debian on my old Toshiba laptop in 2004 (all 16x CDs of it, which a friend had to download for me coz I had no broadband), I couldn't update it because the ethernet network adapter (no wifi) on my laptop was not supported... nice to see that this curse still occasionally persists! If I remember correctly I fixed it by installing a different distro (Ubuntu or Kubuntu, which surprisingly despite being based on Debian had no issues recognizing my network adapter)
