sgdread··on Electromagnetic Waves and Antennas (2016)
YouTube is pretty good at both theory part: there's MIT physics class, but also on intuitive parts (i.e. visualizing how phase arrays work). ChatGPT is also seems to be very good at TA/Professor job when grinding through math-heavy parts: asking intuitively explain things do wonders. And you can also ask lots of stupid questions to understand things.

sgdread··on My total comp for creating GitHub Copilot
Man with ego invents, creates new jobs both at his company and outside, boosts the industry productivity. It's spark that matters; no matter how much wood you bring upfront, it won't burn until the first spark is created.

The system Ahrens describes is more: it has indexing system and an approach to generate new ideas.

github + markdown + cross-page linking works really great with his system.

sgdread··on Ask HN: How did you find your passion?
There is another great book written by Cal: Deep Work [1].

Don't follow your passion. Instead, become really good at something. Apply methodical approach to improve your craft skills. Once you got mastery, you might actually like it.

sgdread··on Equifax statement regarding extent of security incident announced Sep 7 2017
You can put a credit freeze on you file in major credit bureaus - this way their website would not be able to verify answers on security questions and deny login.

Brian Krebs did a good article on the process placing a freeze on your file [1]

sgdread··on Ask HN: How do you reduce unsolicited phone calls?
Here's what you do to significantly reduce telemarketers calls:

1) Go to https://www.donotcall.gov/ and register in the National Do Not Call Registry

2) Wait 31 day (it takes some time to propagate this information to callers)

3) Start reporting unwanted calls via link above

I have not received a single telemarketer call over a year since I started doing that.

FTC is also very good at dealing with collection agency calls if you are not the person they are trying to reach. I received personal apologies from ERC after filing complaint through FTC website.

sgdread··on Show HN: A search engine that doesn't track you, where users vote for results
I really like the idea. However, let's think about abuse patterns: what prevents CEO agency from creating 1k t2.micro instances and clicking upvote for a link of interest and downvote all the competitors?
sgdread··on Ask HN: What's your 'Why should i hire you?' response?
You don't have to kiss ass. Instead, you can deflect and let interviewer answer the question. Something like this "I saw that X corp has an open position. This is an opportunity for me because ... , so I reached you. I assume, you are looking for is a qualified candidate who can do the job described. I saw the requirements and, I believe, I am qualified candidate. If you are not convinced yet, how can I change your mind?"...
sgdread··on What are the complex numbers, really?
You have to start somewhere. Once idea is visualized and internalized on lower dimensions, you move to the next level, where images not needed; however to get to that step 0, where you understand why complex numbers used in AC: lots of folks never bother to explain that it's just the best way to describe rotation.
sgdread··on We’re sorry, and we’re not rolling out the fees change
> They did aggregate up until this point

Still an issue if most people support 1-2 creators with $1-2 pledges.

sgdread··on We’re sorry, and we’re not rolling out the fees change
You can go creative (though, I'm not lawyer, nor accountant): have a minimum payment limit: 5$, for instance; if pledge is $1, then ask to pre-pay 5 units in advance (and be transparent why this has to be this way).
sgdread··on We’re sorry, and we’re not rolling out the fees change
I understand why they do it: they trying to bring down transaction costs with payment processors. These fees on small amounts is death by thousand cuts.

But, I believe, there is a way: they can introduce wallets for $1-2 patrons: put $10 in a single transaction, then charge the wallet once it is a time to pay to creator. This should aggregate small transactions into larger ones and significantly cut the costs.

sgdread··on SF residents get a shock: Someone bought their street
Is public transportation more efficient per mile/person? Yes. Does it solves all the transportation problems? No: it's not covering even half of our needs. Just for reference: only 30% of NY population is using mass transit for commutes. SF is just 15% [1]. And in most areas in the country you can't go and buy some food if you have no car: there is not even a sidewalk, not to mention public transportation. So what you are proposing is to additional burden for the majory of the population for "storing their property" without providing any alternative.

Edit: who pays majority of taxes for road use? It's car owners. You have cheap buses only because car owners paid majority of the bills for road network maintenance and development.

sgdread··on SF residents get a shock: Someone bought their street
Well, car owners can use the same argument: public transportation benefits only people without cars, why car owners should pay maintenance of train stations, buses, trolleys, repair shops for those etc?
sgdread··on SF residents get a shock: Someone bought their street
Nobody is subsidizing your car: as a car owner, you already paid 1) sales tax; 2) yearly registration; 3) yearly property tax; 4) taxes included in gas. Why car owners should be double-triple taxed?
sgdread··on Blue Apron falls 9% on fourth day as a public company
We used it a lot when they just started. For a while the quality was very good: chefs did a good job providing variety of choices, packaging was good. But after a year or so they started to cut the cost and shifted to low-quality selection which felt like fast food. We moved to Home Chef: it's pricier, but they provide what Blue Apron was when they started.
sgdread··on Horcrux: A Password Manager for Paranoids
5c from me:

1) why CTR mode was chosen? I would probably go with something like GCM: privacy + integrity check.

2) IV ideally should be re-generated on every re-encryption. It doesn't have to be secret, but has to be random (securely random).

Client-side encryption and zero-knowledge storage design might give some peace of mind to some users.
sgdread··on Adblock Plus announces members of independent Acceptable Ads Committee
First of all it's not like cable bundle - you pay flat fee to access EVERYTHING like utility (probably % of your ISP bill). Call it content tax, if you will (BBC in UK is funded this way). Internet is NOT free anyway. Then whatever you paid goes to authors in a share proportional to content value consumed (I don't want to go into weeds on how to evaluate fair price for the content, but it's possible).

It is right for content consumer: no annoying ads, no interruptions, no more punishment for using "free" content by being blasted with non-relevant junk.

It is right for the content creator: you rewarded for high quality content, not for ads shows (natural flow of interests) -> no need to beg visitors to disable adblockers (this is what some youtubers do). BTW, IMHO, this is also a very good and organic way to "embrace" piracy - just redirect torrents income share to copyright holders - nobody will ever fight torrents after that point.

Ad companies is unnecessary middle-man in this relationship. And this middle-man will be eventually eliminated for good. I understand that you represent one, but there's still market for ad companies in other areas - where ads are relevant to context (like when I'm searching to get a new car or fix my fridge). Ads should help users, not annoy them.

sgdread··on Adblock Plus announces members of independent Acceptable Ads Committee
Just because it's done this way at the time, it doesn't mean it's right.

To be fair, the monetization of "free" content should be done different way: utility payment model is the way to go. YouTube Red got it right, they just haven't pushed it all the way - eliminate ALL ads. Apple Music and Spotify got it right too.

As a customer, I have fixed amount of hours to spent in a day to consume content, so content providers have to compete for this time to get compensated. If you pay flat fee at ISP level, then it can distributed to content owners minus platform service fee. This way you don't stuff people with gazillions of non-relevant ads and there's natural flow to get higher quality content to attract customers to your site.

Ads are not needed to get "free" internet.

sgdread··on Adblock Plus announces members of independent Acceptable Ads Committee
Context is the king.

Ads acceptable only when their subject matches context of browsing and the user intent. And works only when done in non-interruptible manner. If you break context and/or flow, people get uncomfortable, frustrated, angry. Angry people will install ad-blockers.

Some examples:

- if you search for a solution on how to fix a fridge, then fridge ads are acceptable. Google does exactly that in their search.

- if you're on sports stats tracking site, then athletic gear, food, etc are acceptable

- if I search stackoverflow for specific problem with my code - NO ads please, I'm not in a mood to buy something.

- in movies: John Wick is using TTI Glock 17 - having TTI ad near is perfectly fine (people will crave to know what's those cool things he's using). I.e. product placement is the way to go. What's happening on TV? You're watching Keanu shredding through the movie, then it suddenly stops and Chevy ad coming in. WTF?!111

sgdread··on Hiring without whiteboards
I've got pretty complicated exercises in whiteboarding sessions: some problems with graphs or dynamic programming. The way how I solve those in my daily work is totally different to the way I go in 45 min whiteboard interviews: in 45 min you always have to do it in top-down manner, otherwise you will fail by writing non-relevant parts of the code and running out of time. I usually prefer opposite: bottom-up approach. It's a skill. Very artificial and very dumb to my opinion since you never work this way, but interview supposed to test how you do you work.
