jp0d··on Solar-driven water splitting at 13.8% solar-to-hydrogen efficiency
This is not too bad. I'd prefer hydrogen fuel cells over massive toxic batteries that we're going to have to dispose safely in a few years, from all those used Teslas! I don't know about other countries, but most of the electricity generated here in Australia is from Coal and Natural gas. That's an unfortunate fact. I don't see any reason to buy an electric car until that changes. In the meantime if the solar driven hydrogen production efficiency increases then we can have an even cleaner future.
jp0d··on Dask – A flexible library for parallel computing in Python
Off the top of my head, I can't remember what size nodes we use. I think it's m5x large AWS nodes with 16 cores and 128 GB RAM. Depending on the size of the data I use anywhere between 20 to 80 of these nodes. Sometimes even higher. That's why I've never had a need for these libraries.
jp0d··on Dask – A flexible library for parallel computing in Python
yeah, like others have pointed out, you might be correct about it being a massive overkill for most users. It takes me at least 10 to 15 minutes to spin up a cluster and configure it before I can start anything.
jp0d··on Dask – A flexible library for parallel computing in Python
You're definitely correct about Spark being a nightmare to configure. Luckily we've got data platform teams who take care of that. Analysts like I still do configure parameters depending on the scenario. You might be correct about data in the 1-15 GB being more common. I'm an analyst so most of the time, I've to aggregate data before I do any analysis. But data scientists in my team typically work on smaller datasets and use Sagemaker instances.

ohh yeah. Thanks for pointing that out. I do remember reading this a few months ago.
jp0d··on Dask – A flexible library for parallel computing in Python
Apologies for being pessimistic. I've never had a reason to use dask. I like Pandas only for very small sample datasets. Nothing more than a few MBs. I deal with large amount of alpha-numeric data that can no way fit on a single computer. Even with multi-processing abilities, it's never really that useful and pandas does the job. I've to use large clusters and spark for any real datasets before I even think about using pandas. Spark has its quirks but I'd argue that it has a lot more features when it comes to distributed computing.
jp0d··on Ask HN: Who's not sucky to work for?
Thank you. Glad that you've enjoyed working with us. I can confirm that everyone I meet here have been wonderful human beings! I can safely say that it's a big part of the hiring process, without giving up too much details. :)
jp0d··on Ask HN: Who's not sucky to work for?
I've been working for Xero since three years. It's a great place to work. Free barista coffee, fruits and social gathering every Friday. Everyone is very helpful and nice. Waiting to move into a brand new office here in Melbourne, AU. It's great to work for a company that cares about ethics and governance. We've to jump through several hoops before we can do anything with customer data. I have a lot of freedom in terms what tools to choose for my work. I've never had such experience working for big IT consulting companies prior to Xero.

Disclaimer: I'm a current employee here. I'm a data analyst! I haven't been asked or paid to write this. haha.

jp0d··on Wacom drawing tablets track the name of every application that you open
I one tried using my wife's Wacom tablet on my office Mac. It kept prompting me to allow it record keystrokes from all applications. Naturally I didn't allow it. It didn't work but then the spyware was quite difficult and and hard to remove. I was shocked.
jp0d··on Samsung “Smart TV” showing ads o customers
yeah, the last line is quite true. I saw somebody posted a screenshot of their lockscreen with an ad. I've never seen that on my iPhone. But then with the new IOS, I've stopped all kinds of tracking and notifications.
jp0d··on Samsung “Smart TV” showing ads o customers
Are those cheap? Not being sarcastic. I honestly don't know if they're selling those at a loss. I bought my Sony Smart TV 4 years ago. I don't get any ads. It's got some apps like Youtube, Netflix, Stan etc. and that's it. No ads whatsoever.
jp0d··on Samsung “Smart TV” showing ads o customers
yeah but we can't expect regular people to be able to do that.
jp0d··on Samsung “Smart TV” showing ads o customers
I honestly don't know. But it's incredible that they can just agree on behalf of the customers that ads are okay. That's why I never buy Samsung phones either. They're full of bloatware. There should be a setting to disable these ads.
jp0d··on Instagram has largely replaced TikTok in India and erased working-class creators
To be fair most of the "content" on either of these platforms can be actually labelled as "content". If anything, it probably helped those young people get some real life skills rather than wasting their life in a digital social bubble.
jp0d··on Sony to join TSMC on new $7B chip plant in Japan
What's wrong with that?
jp0d··on Seattle Votes to Decriminalize Psilocybin and Similar Substances
Mate, even cannabis is illegal where I live. It's rarely enforced but still quite ridiculous. I'm not even a consumer but I know a few people who've benefitted greatly from it.
jp0d··on Telegram founder says over 70M new users joined during Facebook outage
Yes, thank you. I wasn't aware of Telegram's shady models. I'll read about it. But its UI is far better than Signal. I don't use FB and their other products, except for WhatsApp. I've disabled all tracking features on IOS just to be safe! :)
jp0d··on Telegram founder says over 70M new users joined during Facebook outage
Some of my closest friends and I moved to Telegram a few months ago. It's actually quite good. I've to be on WhatsApp as it'd be a pain to teach parents how to use a new app!
jp0d··on Seattle Votes to Decriminalize Psilocybin and Similar Substances
This seems like a step in the right direction. It'll help a lot of people deal with mental health issues.
jp0d··on Slack is experiencing a service disruption
It's quite bad at the moment. I can't message anyone at work!
jp0d··on Goats became an unconventional weapon against wildfires
Goats are amazing animals! :D
jp0d··on Earthquake in Melbourne, Australia (9.15 AM 22nd Sep 21, AEST)
ooohh.. mate, calm down. I'm sure he/she wrote that with the best intention. Hope you're okay!
jp0d··on Earthquake in Melbourne, Australia (9.15 AM 22nd Sep 21, AEST)
Thanks for that and you're right. I read that on the SEC website. But, my garden has a good amount of space and has small trees. Far from powerlines. Whereas the house is probably 50 to 60 year old wooden structure built on a sloped block, which trembled quite badly! hahaha. so decided to run with the wifey!

jp0d··on Goats became an unconventional weapon against wildfires
According to this video, they've had some success! I'd be interested in eating those blackberry flavoured goats. hahaha.
jp0d··on Earthquake in Melbourne, Australia (9.15 AM 22nd Sep 21, AEST)
Yes, it's rare! But it's 2021! We've seen many rare things happen! hahaha. Hope you're safe, mate.
jp0d··on Earthquake in Melbourne, Australia (9.15 AM 22nd Sep 21, AEST)
I thought it was some possums mucking around on the roof. My wife thought I'd started exercising on the wooden floorboards! Hope you and your family are safe.
jp0d··on The Framework is the most exciting laptop I've used
It'd be interesting to see a model with ARM64 CPU as well! :)
jp0d··on Earthquake in Melbourne, Australia (9.15 AM 22nd Sep 21, AEST)
I work for a Kiwi company and many of my colleagues are Kiwis. When I posted this on company messaging platform, many of them were surprised that Australia gets earthquakes too. I felt quite strong tremors here in Ringwood, Vic. Wife and I ran out through the backdoor to the garden. It was quite an experience.
jp0d··on Goats became an unconventional weapon against wildfires
I've seen something like this used in Vic, Australia. Apparently goats love Blackberries.

jp0d··on Atlassian fired me while I was taking care of my wife who is fighting cancer
Those are quite commonly used words at Aussie companies. I guess it's just a cultural difference.
