ammar_x··on Ask HN: What tools are game changers for communication in fully remote teams?
Seems like Slack with its new features except for automatic transcriptions and tagging which are useful features of course but I don't see the team switching from Slack to YAC for just these features.

Also, they say it is to replace meetings and I don't think so. Many times you need to meet instead of countless back-and-forth messages.

ammar_x··on Ask HN: What is the best data storage solution for BIG data and fast queries?
I recommend Google BigQuery. Its storage is cheap ($0.02/GB) and can become even cheaper. You can process huge amounts of data quickly and pay $5 for each terabyte your query processes.

It's easy to use too and its version of SQL is quite powerful.

On AWS, there is Athena which works on data stored in S3 and has the same processing price as BigQuery ($5/TB.) However, from my experience, I recommend BigQuery.

ammar_x··on Movie dialogue has gotten more difficult to understand
This post and comments increased my confidence in my English skills.

I don't have issues with understanding my American colleagues and talking with them, but when I try to watch a movie without a subtitle, I feel that I'm far from being good enough in English. I thought I was alone in that, so thanks for posting this.

ammar_x··on Ambient Chaos
I think the sound recordings are great!
ammar_x··on Why and how to use RSS for consuming knowledge
Is there a reliable way to create RSS feeds for sites that don't have them? That would be really great...
ammar_x··on Ask HN: What problem are you close to solving and how can we help?
I'm searching for a (reliable) open-source OCR tool for Arabic text.

The best option I tried is Google Cloud Vision, but it's still not accurate enough, and it could get quite expensive for large tasks.

Anybody knows a good software for that?

ammar_x··on Ask HN: What problem are you close to solving and how can we help?
Please make this a monthly thread!
ammar_x··on Ask HN: What problem are you close to solving and how can we help?
Seems good but the UI can be improved IMO.

I have two questions please:

- Is there a list of all the feeds used by LinkLonk?

- How many users are there today?

ammar_x··on On the link between great thinking and obsessive walking
Summary of the studies mentioned in the article:

- An experiment to look at the effects of walking on creative thinking done by Marilyn Oppezzo, a Stanford University psychologist and her Ph.D. advisor: A group of Stanford students were asked to list as many creative uses for common objects as they could. A Frisbee, for example, can be used as a dog toy, but it can also be used as a hat, a plate, a bird bath, or a small shovel. The more novel uses a student listed, the higher the creativity score. Half the students sat for an hour before they were given their test. The others walked on a treadmill. The results were staggering. Creativity scores improved by 60 percent after a walk.

- Michelle Voss, a University of Iowa psychology professor, studied the effects of walking on brain connectivity. She recruited 65 couch-potato volunteers aged 55 to 80 and imaged their brains in an MRI machine. For the next year, half of her volunteers took 40-minute walks three times a week. The other participants kept spending their days watching Golden Girls reruns and only participated in stretching exercises as a control. After a year, Voss put everyone back in the MRI machine and imaged their brains again. Not much had happened to the control group, but the walkers had significantly improved connectivity in regions of the brain understood to play an important role in our ability to think creatively.

- Jennifer Weuve of Boston University’s School of Public Health studied the relationship between walking and cognitive decline in 18,766 women aged 70 to 81. Her team asked them to name as many animals as they could in one minute. Those who walked regularly recalled more penguins, pandas, and pangolins than the women who were less mobile. Weuve then read a series of numbers and asked the women to repeat them in reverse order. Those who walked regularly performed the task much better than those who didn’t.

The author notes at the end that correlation does not equal causation. He says that perhaps the arrow of causality was pointing in the wrong direction. Maybe mentally active people were simply more likely to go for a walk. Researchers had to dive deeper.

ammar_x··on The Sweden experiment: how no lockdowns led to mental health, healthier economy
The main point of the article for me which is worth contemplating is that Sweden strategy didn't have the anticipated catastrophic consequences.

The article acknowledges that what worked for Sweden would not have worked for other countries with higher population densities like UK.

ammar_x··on Apps Getting Worse
You spoke my mind in this short but spot-on article. I think that this is a problem that deserves to be studied deeply. I've seen many apps turn into really bad UX. Many are mentioned in the comments.

Now the question is: how can we determine whether the new app update is better or worse? I think PMs and developers intend to produce better apps; but don't they realize that their updates are bad? That's why this issue needs more research to be understood IMO.

I think one of the indirect reasons is that in this world of countless options and emerging new things, people (including PMs and developers) don't want anymore to spend their years working on one thing and making / keeping it great. I'm sure there a lot more to it than this...

Very interesting discussion here.

ammar_x··on The journey to controlling external monitors on M1 Macs
You're welcome :) Ans since you deliberately chose this style, I'd be interested in learning from you (maybe in a new post) how you go about the process of writing.
ammar_x··on The journey to controlling external monitors on M1 Macs
Although I'm not interested at all in brightness control and the different technologies you described, I really enjoyed reading your post. Your way of combining talking about technical issues with your personal life and challenges (your company job, having a side project along your day job, the winter cold near your house, etc.) made it possible for me to enjoy reading a post about something completely unrelated to me (DDC, etc.) Nice job.
ammar_x··on Choose whether Search can show you personal results based on your Google Account
This is a great tool, thanks for telling us about it (actually I discovered that I've bookmarked the searx page before and forgot about it:))
ammar_x··on ArchiveBox/ArchiveBox: open-source self-hosted web archiving
When I tried to add my bookmarks from a file, one of the website seems to not be online anymore; archivebox just stops execution when it encounters this issue.

How can I make archivebox ignore such errors and continue with the rest of the websites?

Command used:

  archivebox add < exported_bookmarks.html --depth=1
ammar_x··on The worst volume control UI in the world (2017)
Funny and creative :)
ammar_x··on Show HN: Print a WiFi Login Card
Really cool, despite that some comments show that generating such QR codes can be done with a simple command; because using this service is faster for me as a person who is not familiar with QRs.
ammar_x··on Launch HN: Enso (YC S21) – Visual programming and workflow automation tool
Looks really promising, will give it a try.
ammar_x··on Alien Dreams: An Emerging Art Scene
Thank you for this article, it introduced me to amazing works. I've been very interested in the field of GANs, style transfer, etc.

The best thing is the notebooks which I can play with to generate images. I now have ~10 Colab tabs open waiting for testing :)

ammar_x··on Show HN: Art Generator Neoplasticism
Beautiful tool, thank you. Do you use machine learning in the generation process or it's just rule based?
ammar_x··on If the Moon Were Only 1 Pixel (2014)
This website is a great example for me of useful, interesting, and original things that can be done on the Internet, instead of the abundant nonsense. Hope there was list of these websites.
ammar_x··on Show HN: Influence, a Go-inspired 1-minute board game
Seems fun but makes my fans spin, on Chrome.
ammar_x··on Tell HN: I curate HN stories which didn't reach the front page
We need more things like this: tools that extract valuable info from the overcrowded internet.
ammar_x··on Ask HN: Tools you have made for yourself?
Yes I'm interested in that and would like to know when you release the source code.

And I'm glad you visited my blog and liked that post :)

ammar_x··on Ask HN: Tools you have made for yourself?
:)

Great. Good luck with adding new dictionaries and thank you for your efforts.

By the way, have you seen the work of Taha Zerrouki. He has produced many open source tools to deal with Arabic language [1]. Thought you might be interested.

ammar_x··on Ask HN: Tools you have made for yourself?
I couldn't find results for the Arabic verb: يعيب or its past form عاب. It means something like criticize. Any tips?
ammar_x··on Ask HN: Tools you have made for yourself?
I wanted a way to compare fonts easily and quickly so I built Pair & Compare [1].

ammar_x··on Ask HN: Tools you have made for yourself?
Great! Adding it to my favorite dictionaries.
ammar_x··on Password Managers
Browser built-in password managers are much less useful for me than some password manager apps like LastPass. I can use it in Chrome, Safari, on iOS, macOS, etc.

If I use Chrome's built-in password manager for example and want to get the password for some website in Safari on iOS, I think that would not be as seamless as with LastPass for example.

ammar_x··on Initial Stress-Derived Noun
First time I hear of this as a non-native speaker. I'll pay more attention to notice it in real life.
