lexandstuff··on Google employees are listening to Google Home conversations
One thing that Google Home does noticeably poorly with is disabled voices and non-native speakers. Google Home would be really handy for a family member with down syndrome who can't read nor write but can easily learn voice commands, but Google Home doesn't currently understand him at all. My partner with a Malaysian Chinese accent also really struggles to use Google Home.

That said, I notice the quality of voice recognition is rapidly improving and I'm thankful for the work the Google engineering team are doing; voice recognition and language translation has the potential to improve the lives of so many people.

lexandstuff··on Ask HN: What's your favorite elegant/beautiful algorithm?
Gradient descent is quite amazing in its power and simplicity. If we can figure out a good loss function and a model architecture with enough parameters, calculus can basically take care of the rest.
lexandstuff··on Ask HN: What is the most LGBT friendly company you know of, preferably hiring?
ThoughtWorks is probably the most inclusion / diversity focused company I've ever worked for. I'd highly recommend them.
lexandstuff··on Ask HN: Is anyone else receiving spoofed gmail spam in their inbox?
It's extremely widespread. Take a look at the Twitter search feed for Gmail+spam: https://twitter.com/search?f=tweets&q=gmail%20spam

lexandstuff··on Introducing Pytorch for fast.ai
Part 2 is already out: http://course.fast.ai/part2.html
lexandstuff··on Software developers who started after 35, 40 or 50
In my limited experience, you don't need to have an "aptitude" for programming to get good at it. It just requires a lot of time and patience.
lexandstuff··on 43M passwords hacked in Last.fm breach
Wow - extreme! I reckon we have a few more cracks at solving this problem as an industry before we resort to locking up junior devs.
lexandstuff··on How to move from Amazon RDS to a dedicated PostgreSQL server
Unfortunately, DMS is quite limited for Postgres. We trialled it but found these two limitations deal breakers:

* "AWS DMS doesn't support change processing on Amazon RDS for PostgreSQL. You can only do a full load."

* "AWS DMS doesn't map some PostgreSQL data types, including the JSON data type. The JSON is converted to CLOB."

http://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source....

Hopefully it improves soon, since it's an otherwise awesome tool.

lexandstuff··on Lessons Learned from a Year of Elasticsearch in Production
Article author here. That's really good advice, thanks a tonne.
lexandstuff··on Ask HN: How can I tell if I have programming aptitude?
If you can grasp all those things in less than a week, than congratulations: you're a once-in-a-lifetime genius.

If it takes you years to grasp all those things like the majority of us, then that's fine too.

lexandstuff··on Ask HN: What do you do when an homeless ask you money?
Always give money if I have it. If even a fraction of it goes toward food or shelter, then it's money well spent.
lexandstuff··on Sync 2.0: Skip the Cloud, Share Direct
Paperspace, offering an extreme version of the dumb terminal paradigm, is currently on the front page of Hacker News and Product Hunt, so it's kinda difficult to tell exactly what phase of the cycle we're in.
lexandstuff··on SSH Kung Fu
Aside from the ones already mentioned, there's a library called dot-ssh-config[1] that is useful for generating SSH configs.

lexandstuff··on Serious reading takes a hit from online scanning and skimming, researchers say
Thanks for posting/making this. Using the scroll technique to read the copy on your webpage did appear to feel a bit more "natural" than other webpages. Look forward to experimenting a bit more with it.
lexandstuff··on 80s Typography in CSS
Who would frown upon such an awesome demonstration?
lexandstuff··on A member of our community is missing, help find him
I think the "Thanks for coming. Ok." thing is an in joke. See @isz's Twitter profile.

lexandstuff··on Ask HN: What habit have you dropped or picked up that improved your life?
Giving up high sugar foods completely (no soft drink, candy, dessert etc). I went from battling colds year round to almost never getting them.
lexandstuff··on Ask HN: What habit have you dropped or picked up that improved your life?
That sounds great. Sometimes I really wish I had friends who are into programming.
lexandstuff··on Google Maps personalization could hurt public space and engagement
Even though two people may literally "look at the same map", their experience of it will be completely different. They will both have different places to call home and work; they will have their own mental no-go zones and various other associations. If this article is correct, it seems Google recognises this and is taking it to its logical next step: literally changing the map for the individual.

As far as Google is concerned, services like this are very clearly what they are most interested in offering; convenient personalised digital experiences based on all the data we're willing to feed it. And, hell, they are getting pretty damn good at it!

Which is not to say that local community engagement is not a valid problem to solve. Just that, it's one for a different organisation.

lexandstuff··on Show HN: visual discovery of TV/Movie quotes
I accidentally just attributed Travis Bickle's quote to myself. Looks like someone fixed it though. Thanks!
lexandstuff··on Google Glass
Not a Chinese knockoff, but Vuzix are trying to get a similar product to market: http://www.vuzix.com/consumer/products_m100.html
lexandstuff··on A list of donations that Bill Gates has made
Not quite. At different points in his career, Buffett had large holdings in tobacco and coal. Plus, to this day, owns a decent percentage of Coca-Cola - which I would argue is a pretty unethical investment.
lexandstuff··on Programming from the Ground Up
Great stuff. Thanks so much.
lexandstuff··on CodeWars: the Hacker Society where devs compete
Love it.
lexandstuff··on Show HN: First WebGL app. Uses NOAA data to visualize storm paths back to 1848.
Sexy as hell. Great job.
lexandstuff··on How to Crack the Toughest Coding Interviews
Well, I'm 25. But I'm also a well paid developer (early six-figures in Melbourne, Australia) who would be pretty hopeless in these interviews.
lexandstuff··on Can programmers without CS degrees find jobs?
I'm doing okay working as a developer here in Australia without even a high school certificate. Granted I'm working in enterprise, so I'm not exactly doing the sexiest stuff on the planet. But the money's good, and I love the work. I learned to code a couple of years ago, starting with PHP then Python, and, after putting together a few websites for my team, I managed to transition from a Operations role to an Engineering role, developing a few in house monitoring products.

Good luck.

lexandstuff··on I didn't learn programming when I was 12
Good luck on your journey, Mr Tran. Personally, I didn't start really learning to program until a couple of years back; I'm 25 now. I've managed to transition to a dev role within my company shortly after and I'm earning quite a reasonable salary.
