New top story on Hacker News: Ask HN: Indoor air quality sensors and other IoT that's local-first and not DIY?
Ask HN: Indoor air quality sensors and other IoT that's local-first and not DIY?
29 by TeMPOraL | 19 comments on Hacker News.
I've recently been looking into assembling an indoor air quality monitoring system, and so far have failed to found any solution that would meet the following criteria simultaneously: 1. Connected for data logging, but local-first. That is, no mandatory Internet connection to vendor cloud. Ability to point to my own server (in my local network), or at least download a data dump off device every now and then (even if over a wire, as a last resort). 2. Not strictly industrial-use. I.e. one that doesn't require me to become a large corporation to buy some, and that doesn't require some proprietary, expensive, and/or old-school industrial protocols to talk to. 3. Not DIY at the hardware level. I'm not that good with a soldering iron, and with small children, I have neither time nor workshop space to solder and assemble anything more trivial than "plug a sensor into an ESP32 and screw both into a box". 4. Quality components. With sensors, I mean measuring what it says on a tin (vs. measuring something else and using a factory-provided lookup table to synthesize approximations), and doing it with reasonable accuracy and precision. If there's a calibration step to be done, it should be one that doesn't require me to incorporate myself to perform it. I've spent some time looking at available options and past HN threads, and so far I discovered that: - Most products that fit #2 and #3 fail at #1 - they're predominantly cloud-connected bullcrap, and going by review, they often fail at #4. Occasionally, I find something that fits #2, #3, and #4, but then it fails at #1 by... providing no data export option altogether - apparently, it's enough for the consumer to see traffic lights instead of numbers, or browse the readings from the device control panel. - The DIY stuff I saw (failing #3 to smaller or greater degree) is weak in #4 - in some cases, I recognize the sensors as rather poor and tricky to use right (infamous DHT11 comes to mind), and in all cases, I don't know how one would go about calibrating anything. My questions thus are: - Does anyone here have a setup that solves for these four points, and if yes, could you share some details? - How one would go about looking for vendors meeting those criteria, if they exist at all ? - In a broader sense, how do you go looking for any IoT-adjacent vendor that meets those criteria? It really seems to me that everyone wants me to install their godawful stupid app to connect to their broken cloud, and there's such a flood of those products that reviewers can't keep up with quality testing, and hackers can't keep up with reversing the proprietary protocols and firmwares.

Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do.

New top story on Hacker News: Show HN: Yet Another Node.js Framework
Show HN: Yet Another Node.js Framework
15 by donaldpakkies | 0 comments on Hacker News.
About a year ago, I stumbled upon a new Nodejs language called "Imba", I found this language to be interesting and it seemed like it had a lot of potential. Doing a bit of digging, I realized no one had created a framework for it, so what did a normal dev do? Well, a normal dev went ahead and created another Nodejs Framework, only this time it was meant for Imba. So what did I create? I created a batteries included Framework heavily inspired by Laravel but it runs on Nodejs, and uses Imba as the default language, but you can actually use TypeScript or JavaScript. In fact, when creating a new project using the Framework, you will be asked if you want to use "Imba" or "TypeScript". You can scaffold an Imba SPA or MPA, you can even use React or Vue, it all depends on what you are used to. For more information, you can visit https://ift.tt/G8y1Obf Keen to hear your thoughts

Ask HN: Azure has run out of compute – anyone else affected?
554 by janober | 308 comments on Hacker News.
Last week we at n8n ran into problems getting a new database from Azure. After contacting support, it turns out that we can’t add instances to our k8s cluster either. Azure has told they'll have more capacity in April 2023(!) — but we’ll have to stop accepting new users in ~35 days if we don't get any more. These problems seem only in the German region, but setting up in a new region would be complicated for us. We never thought our startup would be threatened by the unreliability of a company like Microsoft, or that they wouldn’t proactively inform us about this. Is anyone else experiencing these problems?

I built this during Covid. When I released it, some of the parts went out of stock or skyrocketed in price, no longer making this an economic DIY project. Now that things are getting back to almost normal, I thought I'd share it here and request feedback. This is a very niche project for people who like the same things I do: saxophones, Rust, mechanical keyboards and the Raspberry Pi.

Show HN: I built my own PM tool after trying Trello, Asana, ClickUp, etc.
505 by tonypham | 354 comments on Hacker News.
Hey HN, Over the past two years, I've been building Upbase, an all-in-one PM tool. I've tried so many project management tools over the years (Trello, Asana, ClickUp, Teamwork, Wrike, Monday, etc.) but they've all fallen short. Most of them are overly complicated and painful to use. Some others, like Trello, are too limited for my needs. Most importantly, most of these tools tend to be focused on team collaboration and completely ignore personal productivity. They are useful for organizing my work, but not great at helping me stay focused to get things done. That's why I decided to build Upbase. I try to make it clean and simple, without all the bells and whistles. Apart from team collaboration, I added many personal productivity features, including Weekly/Daily planner, Time blocking, Pomodoro Timer, Daily Journal, etc. so I don't need another to-do list app. Now I can use Upbase to collaborate with my team AND manage your personal stuff at the same time, without all the bloat. If these resonate with you, then give Upbase a try. It has a Free Forever plan though. Let me know if you have any feedback or questions!

Monumental (if correct) advance in number theory posted to ArXiv by Yitang Zhang
766 by gavagai691 | 229 comments on Hacker News.
Yitang Zhang, the mathematician behind the 2013 breakthrough on bounded gaps in primes, posted to the arxiv today a result which (if correct) comes close to proving the nonexistence of Landau--Siegel zeros: https://ift.tt/WhgyH37 . To give a sense of the scale of this claim: If correct, Zhang's work is the most significant progress towards the Generalized Riemann Hypothesis in a century. Moreover, I think this result would not only be a more significant advance than Zhang's previous breakthrough, but also constitute a larger leap for number theory than Wiles' 1994 proof of Fermat's Last Theorem (which was, in my opinion, the greatest single achievement by an individual mathematician in the 20th century). Some discussion / explanation of Siegel zeros and Zhang's claim can be found here: https://ift.tt/7PWecsf... https://ift.tt/w4f6ToZ... An account of Zhang's remarkable story (and his previous breakthrough) can be found here. Famously, prior to his breakthrough, he worked at Subway and lived in his car: https://ift.tt/2RT1kPv

New top story on Hacker News: Does anyone else finds AWS and other Amazon services overly complicated?
Does anyone else finds AWS and other Amazon services overly complicated?
18 by damacaner | 13 comments on Hacker News.
I think AWS and its signature system is making things more complicated than it should be, like this is a normal signing in process to API: 1. you request client credentials, which is normal. 2. construct request URL, normal. 3. add headers, eh, normal. 4. signature... fuck. First you need to convert the URL you have from step 2, mash it with headers from step 3, add header keys to signed headers, then sum256 hash the payload and hex encode it. Then you create a sign, add algorithm, request date time that is formatted with ISO8601 but all special characters stripped apart, add credential scopes, hash the canonical request you created at the first step. Then, you calculate this abomination: HMAC(HMAC(HMAC(HMAC("AWS4" + kSecret,"20150830"),"us-east-1"),"iam"),"aws4_request") after that you calculate this: signature = HexEncode(HMAC(derived signing key, string to sign)) after that you create an authorization header and add signature to it: Authorization: AWS4-HMAC-SHA256 Credential=AKIAIHV6HIXXXXXXX/20201022/us-east-1/execute-api/aws4_request, SignedHeaders=host;user-agent;x-amz-access-token;x-amz-date, Signature=5d672d79c15b13162d9279b0855cfba6789a8edb4c82c400e06b5924aEXAMPLE ...I mean what the fuck? I can understand why people choose Azure over AWS for the sake of freaking simplicity just by looking at this sign and request process. It feels overly-complicated. Does anyone feels the same while working with this abomination?

I think AWS and its signature system is making things more complicated than it should be, like this is a normal signing in process to API: 1. you request client credentials, which is normal. 2. construct request URL, normal. 3. add headers, eh, normal. 4. signature... fuck.

New best story on Hacker News: Ask HN: Comment here about whatever you're passionate about at the moment
Ask HN: Comment here about whatever you're passionate about at the moment

Hello stranger. It has occurred to me that one of the crucial elements of the early internet was the feeling that there was somebody out there, _somewhere_ on the globe, that was actually responding to that particular thing you were putting out there. It was a special feeling, because it was a sense of connection. Just being online and being part of the few select communities that existed back then was a commitment, and I believe that's in part what made it feel special. With all the world gaining access to the internet, I think we've gained a lot, but lost this sense of wonder: Since online interactions have now become commonplace to the point of para-social meaninglessness, any single post or message doesn't really feel all that _real_. HN is still the closest thing I know to that primordial kind of internet, and so I'm putting this post out there. It might get buried instantly, or it might survive, and on the off chance that it does: I encourage you to comment here about whatever you're passionate about at the moment, however niche it might be. It might let you find some likeminded people and maybe recapture a bit of the best aspects of the internet in those early days. In any case, I sincerely wish you a great day, from one surprisingly-real-but-currently-text-based being to another :)

New best story on Hacker News: Tell HN: A hacker's life is in danger, your awareness may be life saving
Tell HN: A hacker's life is in danger, your awareness may be life saving
674 by michaeltimo | 64 comments on Hacker News.
It's been a month that Jadi (real name: Amir Emad Mirmirani), an Iranian geek, has been imprisoned in Iran's most notorious prison called Evin in Tehran. In Iran, he is one of the most famous people active in the field of programming and computer education. In his personal blog[0], he has been writing about technology and society for years. He has also a YouTube channel[1][2] to teach and encourage Iranians to programming and Linux, and a podcast[3] that has been explaining technology and science news along with his comments for several years. All this in a country with a dictatorial government where standing in the right place has a heavy price. His arrest occurred on October 5, a few days after the recent nationwide protests[4] began in Iran. Arrest at home with beating. The reason for this is not yet clear, but it is probably due to his efforts to increase awareness of the society about Iran's internet censorship system, and his positions against a company called ArvanCloud. Many claim this company help the government of Iran in implementing the internet censorship's system (something like Great Firewall of China). In Jadi's own words, this company has made it possible for the government to turn the Internet into an intranet at any moment and block people's access to international services. Something that happens in every demonstration in Iran including right now. The reason I am writing here is to raise awareness about him, which may lead to his release. All this may be nothing more than a false hope, but it is what I can do. From the news he covered in his podcast, it could be guessed that he is one of the regular readers of Hacker News. Perhaps hearing your support here will boost his morale behind bars in Evin. The prison which is also known as Evin University due to the number of educated political prisoners [5].
