Things I Wished More Developers Knew About Databases
A very long article about the different things different databases do. Although it doesn't focus on specific databases, a lot can be inferred from the points.
... although it focus on relational databases only.
Another point that I could add here is that you should pick a database for making your data read ready. For example, if you built some sort of response and it basically doesn't change, it is ok to put the whole thing in a database (in JSON format or using a key-value database instead). Putting the work of doing sums and averages and whatnot outside the database can really save your butt.
"Studio Ghibli Wallpaper" for use in web conferences, etc.
Studio Ghibli, of "Princess Mononoke" and "My Neighbor Totoro" released a bunch of wallpapers for people to use as background of their videoconferencing or even computer wallpapers.
And it's free.
(This was a pain to finally find it in full: It was a toot on Mastodon, which took me to BoingBoing, with pointed to OpenCulture, which finally went to Studio Ghibli website with the images.)
Understanding Free Cultural Works
Creative Commons, known for their licenses-for-not-software (sorry, I can't find a better description) released an article explaining the different types of licenses they have.
And yes, I'm sharing this 'cause I am, again, worried about the amount of stuff that doesn't get a proper license and may be abused.
Crashes and Traffic Are Down by Half, Saving State $40 Million Per Day During Shelter-In-Place
While we sit on our houses, wondering when we can get out again -- some of us wondering if we could get out at some point -- some things seem to be improving outside the COVID problem.
After India reported dramatic reduction in pollution, now California is reporting that, due people staying at their homes, the number of traffic accidents reduced the costs taking injuries, damages and deaths.
Not that we should raise a statue to COVID, but at least some good things are coming out of this lockdown. Let's hope we can make these results permanent in the end.
Google Apple Contact Tracing (GACT): a wolf in sheep’s clothes.
Contact Tracing is one of those things that look good in theory, but when confronted with the challenges of privacy, doesn't seem so great.
The idea behind Contact Tracing is to make mobile devices talk to each other, so in case someone finds out they got some transmittable disease, like COVID, authorities can trace back who had contact with that person. It's good 'cause you can alert those people earlier, preventing some huge explosion of contamination cases around.
But the problem is that the owner of said mobile device can't opt out of this. The data is not kept in a secure place -- like the person mobile device -- but shared on the respective device company.
And how long till COVID is gone and this is used to trace, say, who some journalist spoke when they got some information that puts pressure on a government? True, I'm again jumping into the slippery slope of fallacies, but we need to worry about those things when mobile devices are basically part of us: We don't recall our appointments 'cause our devices do that for us; we don't remember our friends phones 'cause it is in the device.
Building Finite State Machines with Python Coroutines
I found more curious that Python has corotines than the idea behind using them for state machines.
The only point I see is how weird the floating
yield appears in the code and
how non-Pythonic the corotine appears (
send? Where that came from?)
How Does Facebook Know So Much About Me?
Dunno if it is because I cancelled my Facebook account, but I've noticed some decline in the number of news about Facebook privacy "standards".
This is a short summary of what Facebook does to collect information about you, even some without your consent -- a few weeks ago, there were some news about a board member admitting they have "dark profiles", information about people that do not have a Facebook account.
Decoding the Privacy Paradox
Knowing that our data is being captured everywhere and doing nothing to change that is the so called "privacy paradox".
An interesting and sad read.
Doing more with less time: critical skills for productive programmers
While this is focused on developers, one thing really hit me hard:
Output = Productivity × Time Worked
Why? Because a lot of things around here in Brazil -- industry, specially -- try to focus on increasing output by changing the "Time Worked" instead of focusing on "Productivity", using better tools or investing in better equipment.
And while it is not mentioned in the post (although it mentions the limit of "time worked" though), we, developers, can also take a look on increasing Productivity. The easiest way is to automate the heck of what we can: The less time we waste on bureaucratic/repetitive actions, the more we can produce. Some harder way is to change our current tools to something that can take less of our time, and that's harder 'cause we believe we will "lose time" learning something new or changing our workflows.
On Writing Well
For someone like me who is constantly writing something -- either blog posts, either translating/writing a book, or just outputting small opinions about diverse topics, like I'm doing right now -- having a proper idea on how to write is important.
And I feel like I need to share this 'cause what I put on this kind of post is only a short amount of what I read. Most of the links I save to read later prove to be just short pieces of opinions but some are very complex and hard to follow due their writing style. If I get tired reading, I won't get the point and if I don't get the point, I don't think I should reshare -- no matter how interesting the topic at hand is.
