opmac··on What If Planet 9 Is a Primordial Black Hole?
Primordial black holes were formed during the big bang. That's the only way we think such objects could form.
opmac··on Reddit was down for over two hours
I'm not sure how you can say Wikipedia is static, even by comparison: https://en.wikipedia.org/wiki/Wikipedia:Statistics
opmac··on Reddit was down for over two hours
You've managed to say a lot without really saying anything.

You make plenty of baseless assumptions about my background and ambitions... but I'm not even going to try to address my professional experience (or lack thereof) because it doesn't matter, since you're just using it as a straw man to deflect criticism.

The facts are as follows: 1. Reddit is one of the highest visited websites in the world. 2. Throughout nearly their entire history, they've struggled to put together a way to make money. 3. They have notorious uptime.

Of course they have talented engineers... it would be a surprise if one of the worlds most popular websites didn't.

That doesn't change the facts that they continue to look and function like they're straight out of 2005 (does their search even work yet?), lack a semi decent mobile experience, and have contributed essentially nothing to the technical community in their entire history.

What's your point? Wikipedia is Alexa rank 10 and has ~300 employees.
opmac··on Reddit was down for over two hours
Meh... they could have rewritten the site from the ground up, including any sort of data migration, multiple times over by now. I have never worked there, but outside looking in, it seems like there is a significant lack of technical vision from them.

Other big players like Facebook, Twitter, etc, are literally inventing pivotal parts of the modern web technical stack. What has come out of reddit?

opmac··on There is no evil like reCAPTCHA
To offer a counter-experience, I don't remember the last time I actually HAD the "click once" captcha. It's always "click the buses/traffic lights/store fronts" etc.
opmac··on The Raspberry Pi 4 needs a fan
But they do work without issue, until you start stressing the CPU. In the majority of normal workloads, you don't run into thermal throttling, especially if not using the official case.

Also, if you have the official case and want to do this mod - for a few bucks more than the cost of two "pi fans" (which run $8 on Amazon), you can get a well designed case with heat sinks and a fan.

I see very little reason to actually do this mod versus buying a properly designed case besides the urge to tinker.

opmac··on The Raspberry Pi 4 needs a fan
They sell cases with heatsinks and fans for $10-$20. I would just recommend buying one of those versus modding one like the guy in the article did.
opmac··on The Case for Rooms
Found the guy who didn't read the article, not even the first paragraph.
opmac··on We're Entering a Golden Age of Podcasts
Seems like audio books would be a good addition to your list of media consumption.
opmac··on Just because it’s falsifiable doesn’t mean it’s good science
Commenting on the headline versus the contents I see.
opmac··on An Anti-Facebook Manifesto, by an Early Facebook Investor
Of course. All it requires is some naive (usually older) family members. In this case, my in-laws are in their 70s, and extremely right-wing. They would share stuff from the Nation in Distress group all the time before Facebook banned it. That is just one example; Facebook has been extremely instrumental in providing a platform for disinformation and propaganda. Just because you don't see it in your own bubble, does not mean it is not a threat.
opmac··on An Anti-Facebook Manifesto, by an Early Facebook Investor
Not sure about threats, but I've seen plenty of fake news, conspiracies, etc; many of which have been tied to Russian disinformation groups (or other malignant foreign interests). See the Nation in Distress group; https://www.washingtonpost.com/technology/2018/10/11/faceboo....
opmac··on An Anti-Facebook Manifesto, by an Early Facebook Investor
Unfortunately I believe your myopic viewpoint is exactly what Facebook has driven to create.
opmac··on Google transferred ownership of Duck.com to DuckDuckGo
To offer an alternate experience, I use DDG for nearly everything and have for many months. I have very few issues with it. For the more esoteric searches, I do find Google to be slightly better, but for 99% of my everyday browsing, I have zero issues with DDG.
opmac··on Amazon S3 Block Public Access: Protection for Your Accounts and Buckets
But do you realize that IAM is an industry wide standard acronym? It's not exactly unique: https://en.wikipedia.org/wiki/Identity_management

> Identity management, also known as identity and access management (IAM)

opmac··on Amazon S3 Block Public Access: Protection for Your Accounts and Buckets
IAM isn't a cutesy name. It literally stands for Identity and Access Management.
opmac··on Am I logged in or not? GDPR case study on the example of Chrome browser change
Same, I just made the switch today because of this change. We'll see how it pans out.
opmac··on Host Your Blog on DigitalOcean with Docker, Nginx and Let’s Encrypt
GitHub pages with HTTPS support is easier :P
opmac··on Fidelity Introduces Zero Expense Ratio Index Funds
I asked what the tax implications were for performing a backdoor IRA conversion for an account I hold with them, and what they told me regarding tax implications was straight up incorrect. I did eventually speak to an accountant, which is how I wasn't burned by them.
opmac··on Fidelity Introduces Zero Expense Ratio Index Funds
Didn't become rich? He said he's worth about $100 million. Maybe less than expected for the founder of $5 trillion investment firm, but he's most certainly "rich". Also, almost no employees? According to Wikipedia they have over 16k employees. And I don't know how you know their cash flow, considering they're privately held and that information is not out there, but their AUM is over $5 trillion so it's hard to believe they'd have any sort of cash flow issues.
opmac··on Fidelity Introduces Zero Expense Ratio Index Funds
This is true to my experience as well, although I'm still a loyal Vanguard customer. I actually got dubious tax advice from a Vanguard rep that could have screwed me if I didn't do a bit more research. That being said, I do tend to prefer them over Fidelity (I am currently a customer of both), but maybe it's worth taking a closer look now.
opmac··on Fidelity Introduces Zero Expense Ratio Index Funds
The term "not-for-profit" is almost meaningless here. They are not a charitable organization or advocating the social cause of "helping people invest". Vanguard makes profit. They probably make a crap-ton of profit. In fact, that's their main goal - to make as much money as possible. The caveat here is they don't have shareholders to report to, nor are they obligated to publicly report their financial statements. The top dogs at Vanguard probably make insane amounts of money all the while being "not-for-profit"... and nobody really knows because this stuff is private.

And I say this as a Vanguard customer for over a decade now, and I will probably continue to purchase funds from them for many reasons. But don't be fooled by thinking that they are doing some sort of public service by being "not-for-profit".

opmac··on The physics of infinity
While you are technically correct, that's pedantic and doesn't impact the conclusions of this article one bit, nor does it really add to the discussion. It's written for the layman, and chose to purposefully ignore technical details such as lim x->0+ 1/x = +inf and lim x->0- 1/x = -inf.
opmac··on Introducing Jib — Build Java Docker images better
Yea I don't understand the original comment... however it is true Java isn't (or at least wasn't until recently) ideal for containerization, since the JVM would not obey things like cgroup limits for memory and CPU. This was fixed in Java 9 and backported to the Java 8 (update 131) however there are still potential issues regarding CPU isolation that are not trivially solved without some explicit configuration.

For a good overview, see: https://mesosphere.com/blog/java-container/

opmac··on Linux: Introduce restartable sequences system call
Ah yes, the ubiquitous middlebrow dismissal (https://news.ycombinator.com/item?id=4693920 http://www.byrnehobart.com/blog/why-are-middlebrow-dismissal...). "As a non-kernal guy" gives it away immediately.
opmac··on How to be a Manager – A step-by-step guide to leading a team
This was a fun and informative read. Thanks :)
opmac··on Signal-desktop HTML tag injection advisory
OMEMO actually implemented the double-ratchet algorithm developed as part of the Signal Protocol. Signal, in my eyes, is still the benchmark for balance between usability and security. That's fine if you prefer XMPP w/ OMEMO, and it's arguably just as secure.

...but it's unfair to call Signal another IM silo that's "hostile" towards other clients. Signal is 100% open source, along with the Signal Protocol which powers it all. It is community supported and wholly dedicated to brining cryptography to everybody. The latest implementation of OMEMO as it exists today would not be what it is without Signal.

opmac··on Signal-desktop HTML tag injection advisory
Ah, Electron /sigh.

Luckily this is fixed in the latest version (v1.11.0), so if you're a Signal user (you should be!) and you haven't upgraded already, you should upgrade immediately.

opmac··on Stripe Atlas for LLCs
You should probably talk to an attorney, but as I understand, Florida isn't a bad state to consider either. It really comes down to cost savings and specific laws, and where you're primarily doing business.
