JaggerFoo··on MQTT vs. Kafka: An IoT Advocate's Perspective
I designed a facility IoT system with AWS products: IoT Core (MQTT broker), SiteWise (analytic dashboard), S3 and Lambda. I found the AWS offerings to have everything I needed in one place with a low cost. Added benefits were being able support NIST cybersecurity requirements (CMMC v2, Level 2) in addition to the IoT system.

I was a fan of NATS and Kafka in the past, but AWS tooling makes IoT relatively easy.

JaggerFoo··on Project Sunroof
Not useful for off-grid and no battery options.
JaggerFoo··on My employer is reneging on its remote-work promise
The horror. What's this world coming to.
JaggerFoo··on ChatGPT Plus
Signed up gave credit card can't use. No specific path to chatGPT paid version, only a link that goes to a page that says full wait till later.

Not what I expected from using chatGPT for free.

JaggerFoo··on Brief structured respiration enhances mood and reduces physiological arousal
I like that they described how each method is performed. The mindful meditation method was a bit different from what I've used, but something I can adopt.

So cyclic sighing can replace mindful meditation, except that it requires more use to reap the benefits.

So now Cyclic Sighing, Mindful Meditation and Binaural Beats are techniques I can call upon in times of stress.

JaggerFoo··on P-22 has been euthanized
Ok, so P-22 was isolated in the Griffith Park area, and in 2014 they captured him for treatment for health issues.

Why not release him in an area where there were other mountain lions, so he can get freaky with a female, and he would not be isolated?

Why was returning him to an area where he will continue to be isolated in a relatively small area, with contaminated prey and no chance of mating, the best choice for the animal?

JaggerFoo··on Binance freezes withdrawals of stablecoin USDC as investors pull $2B
Wow, a lot of histrionics in the comments.

Like a wise man once said: "First principles, Clarice: simplicity. Read Marcus Aurelius, Of each particular thing, ask: What is it in itself? What is its nature?"

The article is dealing with a foreign unregulated crypto-exchange and a US regulated stable coin.

JaggerFoo··on US Department of Energy: Fusion Ignition Achieved
Ok, so how long do I have to wait to get a coffee-can sized device to power my house?
JaggerFoo··on Alameda took 1B hit in mobileCoin trade to prop up FTX
The article is short on details of the trade, mostly filler on already reported FTX downfall and other downfalls.
JaggerFoo··on FTX’s ownership of a U.S. bank raises questions
The PR for the investment doesn't imply nefarious intent.

Why would they post a PR announcement if they knew it was an illegal transaction?

JaggerFoo··on Ask HN: What is the most impactful thing you've built?
#1 Computer simulation of automobile emissions testing, that proved more stringent emission standards could be implemented in the state of California.

#2 Space shuttle launch system programming

JaggerFoo··on 3D OpenStreetMap
I'm very impressed. There are places along the US border that show the buildings and lanes for crossing into the US distinctly with labeling.

Can this be embedded in a mobile app?

JaggerFoo··on Product Market Fit
For serious analysis of "Product Market Fit", you are better off searching google scholar than reading this article.

JaggerFoo··on Helix: A Neovim inspired editor, written in Rust
I've used vi from Linux terminal sessions for more than a decade, and VS Code as a GUI editor now most times when not in a terminal session.

Am I missing something not using a GUI vi editor? I came across some dude on YouTube that calls himself "The Primeagen" that swears by VIM, but I couldn't follow his use of it.

JaggerFoo··on I Listened to 1000 B2B SaaS Sales Calls
Great article. Not what I was expecting. The article was informative, actionable and concise.

I learned several things, and laughed at the "When You're Asked To Update Salesforce" meme, which I observed first hand after implementing SFDC and customizing workflows designed by Sales and Product Managers.

I'll be taking a look at Scratchpad and Dooly for sure.

I wonder if the sales teams followed any particular method as depicted in books like Spin Selling or Cracking the Sales Management Code.

Thanks for sharing your insights.

JaggerFoo··on Nocodb: Turns Any MySQL, Postgres, SQLite into a Spreadsheet with REST APIs
Unfortunately, these tools only provide basic record listings with form views.

Except for being able to render images, they don't do much more that database browsing tools.

JaggerFoo··on Celsius Execs Cashed Out $40M in Crypto Before Halting Withdrawals for Customers
Yeah, decentralization is the cornerstone of crypto. The reality of it all is that it is not. But don't tell that to the zealots.

I'm pro-crypto, I think the innovation and paradigm are brilliant - I am developing a small project in crypto. I don't fool myself into believing the hype that exceeds it's capabilities, project organization or true architecture at hand.

Cheers

JaggerFoo··on The Ethereum merge is done
Don't forget about the Merge song "Pandas are not known for running" - a true classic.

JaggerFoo··on Show HN: Query SQLite files stored in S3
I read of someone using AWS EFS for sqlite, which has nfs functionality, if I recall correctly.

However I like the idea of using a local store with litestream to S3 and updating to the latest db data from S3, if using my application on another device or computer. Sort of like github.

Tailscale was looking into this option, instead of Postgres and other DBs. https://tailscale.com/blog/database-for-2022/

JaggerFoo··on Tether will not freeze Tornado Cash addresses
Way to go Tether you're our decentralized hero! You're so awesome! You should book an appearance on "Bankless" and take a bow so the crypto community can bask in your bravery.

Sheesh, crypto is like junior high school.

Cheers

JaggerFoo··on Republishing a fork of the sanctioned Tornado Cash repositories
Analysis of Address Linkability in Tornado Cash on Ethereum: https://link.springer.com/chapter/10.1007/978-981-16-9229-1_...
JaggerFoo··on Republishing a fork of the sanctioned Tornado Cash repositories
I deleted my TC repository clones, before the shit hit the fan, when I was studying TC's use of Zero-Knowledge Proofs. I'm glad they still exist, but if not there are other repos like Zcash.

There are research papers that show that TC withdrawals can be linked to TC deposits with a good level of confidence.

I'm sure a great deal of analysis was done by the US, which led to their actions, like it or not.

There are knee-jerk reactions in the Crypto Community fearing that they will be next, and restricting access to their projects. No self-awareness of the truth about the "Decentralized" nature of their projects.

Cheers

JaggerFoo··on SQLite is not a toy database (2021)
I started to use Postgres on AWS for a personal project, after fighting with several non-docker VM's - I don't want to use docker. But I decided on SQLite + Litestream, hopefully for free on AWS. The simplicity of deployment is great.

SQLite to my surprise has much of the same SQL functions as Oracle and Postgres. I wanted to use window functions, which are supported.

Sqlite came to my attention when I read a Tailscale blog article stating they will be using it.

JaggerFoo··on A simple guide to quadratic voting
Yes the new world order is crypto contracts running things, oh wait we need to convene a council so humans can review potential threats before they are allowed to transact with the contract.
JaggerFoo··on Solana stablecoin violently de-pegs
So the problem was that Nirvana's Oracle Feed, that reported the price of ANA, was manipulated into showing a market price higher than was purchased by the exploiters. Who then sold their ANA back at the higher price for USDT, thus making a profit.

So how was the Nirvana Oracle manipulated to report a higher price for ANA? My guess is that the large purchase was enough to push the price higher (by 35%) and make the flash loan transaction profitable.

JaggerFoo··on Solana stablecoin violently de-pegs
So is this a case of Nirvana code that allowed it to be exploited? I don't see flash loans as being inherently bad, as tweets and articles play it up to be.

I imagine professional/sovereign exploitation teams are looking for contracts that can be exploited, and have tooling and workflow processes in place to test exploits before deploying on a live blockchain network.

This is what Jeremy Siegel has been saying for the past few weeks.

But everything is OK.

JaggerFoo··on Spf13 is leaving Google
#1 Continue working with exceptional people.

This is what I miss the most nowadays. Being the number one item is proper placement IMO.

Go is fantastic and makes it easy to build. Hugo is great too - I'm currently using the Docsy template to avoid/replace multiple software products for a crypto/blockchain project.

Cheers
