I've worked in many fields in the industry, mostly SRE/DevOps, cybersecurity, etc. Coding-wise, I've worked on a PaaS for deploying apps on Kubernetes, on e-commerce backends, path-to-production pipelines, a platform for spinning up Spark clusters. I also contributed to Kubernetes, Linux and Python’s pip, among others.

I have a collection of Macs from the 2000s, including the iBook G4 and the iMac G4. The iBook G4 still connects to wi-fi, and I've seen this update prompt on my iMac G4 (which is connected to Wi-Fi using a mini wireless access point).

I use my iMac G4 to play songs on iTunes, I keep my music library on a server with Samba installed and I mount the volume with the files. I love the Cover Flow design from older iTunes. I can also push songs to my iPod this way.

You don’t confirm focus… pictures are always a bit blurry, but I kind of like the aesthetic (not very practical though).

I did a bit of research, for better results you can try:

- focus peaking

- focus magnifier

- aperture priority (so that it would choose the shutter speed for you)

- and you still would need to confirm focus manually with you naked eyes

I like to capture shots with subjects in an ideal distance where I can have some interesting bookeh but still capture the subject. The bookeh on the Helios lens is beautiful!

If you consider how long lower speed shutters will take and the aperture combinations, it would take a long time to take all the pictures and would stop being feasible.

I don’t know if I follow. You mean to keep a fan moving, take pictures with all the different combinations (aperture and shutter speed). Then merge on an MP4 file that you can lookup somehow the setting combo with the frame?

Sounds… reasonable I guess! I guess it can be simpler than I imagined. The owner of the site just needs a fan :-)

That's what capitalism does – it isolates individuals and destroys communities. No wonder why so many people are befriending AIs and there's a "loneliness epidemic" going around.

When it comes to physical communities (e.g. neighborhoods), I think about some neighborhoods in São Paulo that are being destroyed by buildings and construction sites everywhere [1]. So many neighborhoods full of stories and friendships and people who took care of each other, now becoming part of this massive verticalization, speculation and isolation. Neighbors have to leave due to construction companies' harassment. The ones that decide to stay have to live without their friends around, in neighborhoods that grow more dangerous, with worse traffic, with less small businesses and without knowing who are their new neighbors (which aren't even long term living). Their houses look exactly like Carl Fredricksen's house from Pixar's Up.

When it comes to digital communities, I can only be reminded of how Orkut and MSN defined lots of adolescences in Latin America. Orkut literally had the concept of communities, where people gathered around similar interests (just as the early web's forums). I made a lot of friends in Orkut and MSN Messenger, some of them are still my friends after more than a decade. Facebook tried to recreate the idea of communities (with their groups), but Facebook is pretty much dead for younger people. And Instagram is just so isolating. It has a whole lot of standardized and algorithmically curated content that alienates you from other human beings.

I believe the reason why Orkut (owned by Google) was killed was that they wanted more users, maybe to compete with Facebook. But Orkut was too localized, it basically talked to Brazil and some other countries in Latin America, and India, where it was created. After killing Orkut, Google invested a lot on Google+ (do you remember that fiasco??).

This is honestly the best and most simple way to learn photography, at least something basic that is still very hard to grasp sometimes. I know photography is not just about the photometer, and about depth of field, but this simple simulator helps to learn about these relationships between aperture size, shutter speed and ISO which always bugged me (sometimes my shots were bad and sometimes great).

From the website:

If I ever find a good moving prop like a small fan, maybe I'll also re-shoot new previews to demonstrate how shutter speed affects moving objects.

Now, I'm just not sure how would one simulate a running fan with a picture. While for a static image you can have separated foreground and background and then apply effects for simulation (I know iPhone HEIC images have this property), for moving images you have to simulate the blur and the stillness, which is probably more difficult in terms of coding.

That's why I love fiddling with analog cameras for a bit, or even experimenting with old lens on newer DSLRs. I have a Canon Rebel from 2011 and sometimes love to use my soviet Zenit Helios 44M lens in it. I do have the Zenit which came with this lens, but I have yet to develop its film.

I've applied for some jobs such as Technical Account Manager and mostly Backend Software Engineer (which is probably way more difficult to ace than infrastructure for me). Project Management is definitely something I don't have any experience with.

Why would someone in their sound minds allow their kids to do some sort of facial age estimation made by a third-party vendor? Sounds like a great privacy-protection idea (/s).

You see, these companies leverage the lack of regulation regarding platforms. I'm not sure how one company would fight predatory users, but shifting the blame to parents or doing some techno-stuff to save the day won't do it.

We can already imagine a lot of problems with this approach – what if the vendor forgets to delete these pictures? It can be maliciously, or by sheer stupidity. What if the pictures leak at some point? Again, not every system is 100% safe from bad actors.

Last but not least – do we know if this age estimation algorithm works 100% of times? Are there studies that prove that predators won't find ways to crack this?

Also, kids in the same age group might also misbehave.

Algorithm will be 50/50 - it could either be gore or AI slop.

These things are way better to see than stupid AI. It’s not going to “sell”, but it’s a tech person being creative and doing their craft.

I used to study a lot of hobbyist OS development in my late teens. It was awesome, I still try doing small kernels from time to time (last one was a RISCV small kernel that printed a message to my partner).

Finally some good news.

Comes in handy. I was doing PS3 hacking a few months ago and most of the tools that were made for that work better on Windows 7. My main computer is an M3 Macbook Pro.

I tried using Windows 11 but it was so annoying. Not only it is huge, but also Microsoft was able to screw up the Windows OOBE process and overall Windows experience so badly. I don't want to setup a Microsoft account just to run these old programs. I mostly wanted a disposable Windows 7 box but I didn't even know if I would be able to make it work with virtualization (emulation maybe).

Wine actually worked great for me sometimes, but it was a bit of a hassle as well.

I don't know what TMBG has to do with Hacker News but I dig it so much. It surprised me seeing such a cool band alongside a lot of tech articles for a bit :)

I feel like Jonathan Coulton, Tally Hall and Neil Cicierega are the TMBG equivalents for 2000s kids like me.

Here’s an interesting video by Atrocity Guide that talks about it. https://youtu.be/A47maEySTdI

I simply love these artists that are so unpretentious. Huge fan of Jonathan Coulton, big nerd and nice guy.

I wonder if Jack Stauber would react the same way.

Hey, I recognize Offensi from the Liveoverflow video! [1]

I've been reading some Google VRP writeups [2] in order to inspire me in my bug bounty journey. There are a few by Ezequiel Pereira and Offensi. There's some really cool stuff, that go beyond XSS.

Brazilian government actually wanted to do it recently, require companies such as Facebook to require that you submit your ID and that you link a phone number to your account. [1] It sure makes things easier for the authorities, since they are also dealing with fake news and hate speech. However, it goes against the LGPD (like a Brazilian version of the GDPR). And it is hard to trust a company such as Facebook to keep data such as your ID. How can you be sure if they're keeping this data safe? How can you be sure they won't sell it?

Somehow porting it to iOS or Android would be really great, since people always take selfies from their phones and post them directly to Instagram.

Programming from Ground Up, by Jonathan Bartlett.

https://download-mirror.savannah.gnu.org/releases/pgubook/Pr...

I was able to learn a lot about low level programming. The problems with this book: the examples are in Intel syntax (I find AT&T's syntax better to read and it's more common to use), and not in x86-64.

Also, Hacking: The Art of Exploitation (https://nostarch.com/hacking2.htm) have a nice introduction on Assembly, from the standpoint of a person doing reverse engineering, debugging with GDB or shellcoding.

QEMU can either be used for virtualization (i.e. running x86 Linux on your x86 Mac) or emulation (i.e. running PPC Mac on your x86 Mac).

As a gen-z born in 99, I can tell that many people who were born in 97-2002 might know a lot of songs by Nirvana, Foo Fighters, Guns 'n' Roses, Ramones. Also, at least when I did the quiz, I knew 1 out of 10 songs, and I used to listen to a lot of pop songs when I was a child.

It would also be interesting to see how the location might affect the numbers, since popular local radio and TV stations might have aired different songs, some movies and series were popular in some countries and not in others, etc. Tom Scott did something similar with Jingle Bells [1].

Something else to note: I missed Hey There Delilah and La Bamba, songs that you can recognise easily if the most recognisable part of the song is played.

Not really a Clojure user, but I made a small API with it once and it blew my mind, especially the design patterns involved. An interesting one is the ports-and-adapters (a.k.a. hexagonal architecture) [1][2] . Basically, all the business logic will be kept at a layer, and all of the functions there should be pure (i.e. they will always return the same information according to your input, and these functions won't cause side effects [3]). Then you would have layers where you can plug databases and REST handling.

And Nubank take testing really seriously. REPL and pure functions makes it very easy to use TDD.

Really fun, kind of trains you to when the situation happens IRL, whether you're thinking about how to escape a shell or if you really did it by mistake.

I love showing this screenshot to people: https://imgur.com/a/ziHqJxB. I was having problems trying to create a jailed shell, so I decided to bind mount /bin. That of course was a bad idea. I gave up and rm -rf'd the mountpoint without unmounting it. The screenshot has the serial logs from after that :P.

I had a good time enjoying my stupidity.

Weird, my iPhone is in English, but I live in Brazil, and couldn’t reproduce it (iOS 13.5.1).

However, a bit unrelated, Siri suggested a website whose title is “Home - Donuts” when I was typing news.ycombinator. And the link for it is just “news”

> and highly lacking good Venmo-like apps

There's a few popular apps that allow you to share payments in Brazil, such as:

PicPay Rappi Mercado Pago

The so-called "super apps", such as Rappi, are getting widely popular in Latin America. Maybe Facebook saw it as an opportunity for turning WhatsApp into their own super app.

It's also an opportunity to kill competition, since almost everybody uses WhatsApp.
