Was laid off 2 months ago from my first real DS job and have 5-6 more months of money left. Have had several interviews with varying success so far...is it normal to have the first few technical interviews kinda suck and end up as a reminder of what you need to brush up on? Any advice? by memes_everywhere in datascience

[–]abnormal_human 2 points3 points  (0 children)

We are actually working in a domain related to your past work (audio/music classification, among other things related to music). We are a lifestyle business, with a lot of people effectively doing more than one role at once. No-one gets the luxury of being a total specialist. Everyone's got multiple hats on.

I don't know exactly what is going wrong for you in these technical interviews, but some of the things I try to figure out when interviewing technical people with a specialty. That specialty could be data science/eng, UI/UX, backend development, architecture, etc--

(1) Is this person going to be able to effectively monkey around our existing systems (written in languages X, Y, and Z, using tools A and B on platforms C,D,E,F,G) to get the data they need to do their job, and then turn their data-domain work into useful deliveries to other team members?

(2) What's going to happen if the tools break? Will this person get stuck, or will they spend a few hours debugging tensorflow/whatever, send a pull request, and move on?

(3) Can this person deploy their data-oriented work into our various environments without a huge learning curve? Can they make their stuff runnable in appropriate ways on other peoples' dev machines? Can they integrate it into our client software builds on various platforms?

(4) If the data work creates dependencies, to what extent will you be able to self-satisfy them? For example, working with music classification, you might need a library to produce mel-spectrograms from content, and that choice might have a whole bunch of constraints on it (portability, language, performance, licensing, etc). Will this person navigate that independently, or will there be hand holding required?

I have a 1 hour "do you understand how computers work" interview that I do with almost anyone doing something remotely technical. This is in addition to other aspects more directly tied to the role, of course..but a lot of people are trying to do stuff with code and just have no idea what is going on one layer below the place where they live..and those people are really not that interesting. Maybe in a big company where there's staff to delegate all out-of-specialty matters to..but not in a place like this.

The biggest risk of hiring someone with a narrow skillset is worrying about whether they will ever be able to get stuff delivered. It's really easy to end up with a specialist working in a bubble making results that don't seem to ever get deployed because they lack the skills or wherewithal to do so. These situations can persist for months or years and end up being costly, but it is also really frustrating to be constantly pulling productive developers away from their projects to provide really basic support to someone on the team who just never developed their general "working around code using computers" skills.

How different is it starting cycling indoors in the Winter and transitioning to road? by NevenSG in cycling

[–]abnormal_human 0 points1 point  (0 children)

See how you feel. At some point it becomes way more about nutrition/pacing than muscle/cardio endurance. Once you're comfortable at a duration, try adding 30% to it and see how that goes. In real life, you'll likely do a mixture of shorter/longer rides anyways.

[–]abnormal_human 0 points1 point  (0 children)

Nah, just go out there and focus on controlling the bike. That will actually take a lot more of your attention until it’s second nature. Don’t try to do big duration the first time you go out. 45mins-1hr is fine. See how you feel the next day and slowly step it up.

[–]abnormal_human 2 points3 points  (0 children)

There's a lot of muscles involved in suspending your body and stabilizing it on the road that don't get as much action on the trainer. We just had our first warm day of the year, I went for a 1hr ride that wasn't particularly strenuous, and my neck is a little bit sore today.

I was also feeling somewhat different muscle activation in my legs--stuff that the road was using that clearly wasn't getting the same load on the trainer. Part of this is because I was riding a bike with slightly different geometry, and part of it is because like many people I am often a bit more upright on the trainer.

What will be more useful to learn, Java or C++? by D-Colon in datascience

[–]abnormal_human 0 points1 point  (0 children)

C/C++. Any competent technical person interviewing you is going to respect that more, and it's a better filter for organizations-you'd-like-to-work-for if they aren't totally steeped in java dog food.

If you know C++, it will be assumed that you can pick up Java if needed. If you know Java, whether or not you're capable of handling C++ remains open.

If you can't write native extensions to python to speed things up, do you really know python? I mean, sure, but 90% of the time I use python, there's something embarrassingly slow that could be made better by escaping the GIL or writing a little bit of C. I could totally see someone without C/C++ skills being blind to that and assuming that however fast the tools work is fast enough..and that's why I would be wary of hiring them.

50% of my tech interview for anyone in a remotely technical role (meaning anyone from a jr engineer to a data scientist to a vp of engineering) focuses on "how computers work". Text encodings, basics of network protocols, databases, unix, concurrency primitives, memory management, how math works on computers, thinking about performance critically, etc. The other half focuses on their specialty. If you never learned (or forgot) that stuff, I'm not interested in dealing with your code.

Anyone try something like this? Thoughts? by DaSkeez in woodworking

[–]abnormal_human 1 point2 points  (0 children)

An awful lot of machinery to replace a few bar clamps and a mallet. And you have to store all of that shit afterwards.

IMO, people make way too big a deal about alignment during panel glue ups. Use the right clamps, do it on a flat surface, and knock the boards around with a mallet under partial clamping pressure until they are perfectly flat. No cauls, no floor jacks, no dowels, no dominoes, no biscuits, no bullshit. The glue is enough.

Clipless riders - if you can't unclip in time how is the best way to fall so you minimise the impact? by BurritoMonsters in cycling

[–]abnormal_human 11 points12 points  (0 children)

You want the meat of your upper arm and thigh to take the hit. If you do that, you'll be fine. Don't let your elbow strike first.

I got into a slow speed crash with another cyclist last year where I badly sprained my ankle going down somehow. I assume that I clipped out then torqued the side of my foot against the ground as it caught my weight, but I'm not really sure. I'd rather stay clipped in through the fall and scrape my arm than do that again.

Deepfakes: Reddit bans subreddit featuring AI-enchanced celebrity porn by madazzahatter in technology

Compare the subscriber counts and press attention. Nowhere near the impact, and remember that I'm talking about the education of the public not just people already playing with ML.

Deepfakes: Reddit bans subreddit featuring AI-enchanced celebrity porn by madazzahatter in technology

[–]abnormal_human 5 points6 points  (0 children)

Because it's important for humanity to begin understanding firsthand what Machine Learning technology is capable of. Deepfakes was a great way to bridge the gap between big technical ideas and something that interests huge numbers of people.

Fake video is going to be used to commit crimes, to win elections and court cases, and to discredit individuals. Fake evidence is going to become more and more convincing as people explore this space further.

It's better for people to have an understanding that this kind of thing is not only possible--it's simple enough that a person with a <$1000 graphics card and some spare time can figure it out.

There has been lots and lots of research into machine learning over the past 75 years. The thing that is changing now isn't that we know tons more about it all of a sudden--it's that the computing power needed to generate interesting results has become affordable to individuals. And as it turns out, if you have the gear, applying the techniques to produce significant results doesn't always take a huge time investment.

Ok, now forget the deepfakes people and imagine if an organization with real motivation and resources/cash/connections wanted to apply this kind of thing to accomplish goals. Pretty scary.

The public needs to understand that the rules have changed so that they are prepared to live with them. Deepfakes might have been problematic, but it also exposed a ton of people to this technology for the first time in a new way--and I don't see another application rising to fill the gap anytime soon.

Now that it's banned from reddit, mindgeek sites, etc it's stuck in a niche, away from the mainstream. Sure, the die-hards interested in the tech or its results will continue to consume it, but we've lost it as an educational tool. And that sucks.

How unsafe is it for a somewhat good cyclist to go on a 100 mile (8.5-ish hour) journey in ~20 degree weather? by aroach1995 in cycling

[–]abnormal_human 9 points10 points  (0 children)

Bad idea.

It takes practice to manage fueling/nutrition for an 8 hour ride. Even without the temperature (which will make it harder). You don't have that experience.

You also haven't built a base of endurance to support this.

And the temperature makes it dangerous if you stop/bonk for too long.

It's just all bad ideas. Get a ride.

[WTB] Sennheiser HD 650 - COMPLETE HEADBAND ASSEMBLY by Its_Me_Jose in AVexchange

[–]abnormal_human 1 point2 points  (0 children)

In my experience, Sennheiser can sell you all of the parts for the HD650 one by one.

I replaced a bunch of stuff (including less common parts) on mine last year after almost 10yrs of wear+tear. They aren't super fast to respond always, and you might not like what they charge, but it is possible to go that route.

Newbie Questions - Smart Trainer or Not? by ifyoucantakeit in Zwift

[–]abnormal_human -2 points-1 points  (0 children)

I tried Zwift and ended up not liking it--it's not that immersive, pretty boring, and the competitive aspect doesn't appeal to me at all.

OTOH, TrainerRoad works great for me. It doesn't try to cross the uncanny valley. It's just what it is. I can read during the rest intervals and focus during the hard ones, with good music through the whole thing.

Bucket list project by 4thstreet713 in woodworking

[–]abnormal_human 1 point2 points  (0 children)

Nice work. I'm planning to do a low-back using Brock's plans this year. Am considering watching the WW rocker videos, too, for a second perspective on some of the techniques.

Did you find that you were able to get good results on the first try, or were you re-making parts to take second and third stabs at the shaping/sculpting?

Any other advice?

Any headphones that create an anabolic chamber background (sound treated room sound). by throwaway545041 in headphones

[–]abnormal_human 2 points3 points  (0 children)

There is a fundamental limit to how much sound you can attenuate by plugging/covering the ears passively. Somewhere in the 30-40dB range IIRC.

Active noice cancellation plays a neat trick to cancel out certain kinds of predictable/steady noise, but it's not real silence.

Treated rooms do not sound like anechoic chambers. Big difference between sitting in a top-end treated recording studio and a chamber. The second one makes some people start to feel deeply uncomfortable/want to leave within seconds or minutes, it's so strange.

Road bike vs hybrid bike speed by Rezoan01 in cycling

[–]abnormal_human 1 point2 points  (0 children)

Heh, "I'm not terribly fit" and "my FTP is 3.88w/kg" don't go together.

Strava power estimation is mostly bullshit. If you want a real number, measure with a power meter, or hop on a trainer and do a few FTP tests over a few months--it normally takes more than one before you learn to take the test consistently.

Can STAX earspeakers get by with playing MP3 files, or do they sound like hot garbage? by ihadaface in headphones

[–]abnormal_human 0 points1 point  (0 children)

TIDAL, Qobuz, and Deezer all offer FLAC streaming, sometimes depending on the tier you buy.

Can you normally pick out MP3 artifacts? This might help you answer the question.

I design DSP for audio applications professionally, so I would be considered a "trained" listener. I score 5/6, whether I'm using $2-300 headphones plugged straight into my laptop or $15k of dac+amp+cans. In that sense, more expensive gear doesn't improve my performance.

It helps to understand how MP3 works inside--makes it easier to predict which sounds the codec will have the hardest time preserving. I hear MP3 most clearly by focusing on less-musical sounds sounds and broad spectrum onsets--percussion, bells, breath sounds, electronic effects, analog domain clipping/distortion, etc. MP3 makes these sounds sound disorganized, sloppy or inauthentic.

Because this is not a problem unless you live in one of these shitty subdivisions where packages are visible from the street and asshole criminals are cruising for them.

What high quality headphones do you travel with for hotel use? by WatchesAndHeadphones in headphones

[–]abnormal_human 1 point2 points  (0 children)

HUGO2 + LCD-i4.

LCD-i4 is what finally cured me of trying to travel with over-the-ear cans. So nice, especially in a hotel room, alone, with nothing to do, to relax with some music and have it sound proper.

Weekly Quick Questions, Wood ID, and Deal or No Deal /r/Woodworking Megathread by AutoModerator in woodworking

[–]abnormal_human 1 point2 points  (0 children)

The main thing to know is: it is veneered. You can't have that grain direction in solid wood and make a sturdy or stable bed.

The most important part of that picture is really poorly lit..so I'm not going to hazard a specific guess. It could be a Mahogany-ish like Khaya or Saepele, or it could be some random jungle wood that was processed/colored to look like that. Not getting a strong Walnut vibe from the picture.

You could try browsing around a veneer vendor and see if you can find something that looks similar..
