GFischer··on Button offers instant gratification for those plagued by airplane noise
There are some markets where the real estate business is insane, you don't get to make those studies.

I once had 30 minutes to make an offer on a flat, I actually matched the asking price... and was outbid an hour later.

Current price for that flat is 50% higher now. I'm still renting :( .

And it was a sketchy part of town with known crime (mostly theft, not violence).

GFischer··on Why New York Subway Lines Are Missing Countdown Clocks (2015)
I had no idea time-domain reflectometry existed. TIL.

I agree that I could also think of several ways to implement it and I'm only a software dev.

GFischer··on Internal emails cause more trouble for Facebook and its C.E.O.
Not true. Me and my family are on Xiaomis, they're on a different level.

I have a company-issued S8 and an iPhone, and I wouldn't trade them for my Xiaomi.

Best part is, they cost less than half of an equivalent iPhone, have better battery and amazing performance.

I used to buy Samsungs (and Nokias earlier before they suicided).

I have an iPad and it's a great piece of hardware, but I don't stand the Apple ecosystem (iTunes in particular is a piece of crap).

Currently waiting for the Pocophone F1 to be distributed by the local carrier. Another slam dunk by Xiaomi.

GFischer··on Udacity lays off 125 people in global strategy shift
You launched an app, I think you could get a job as a junior programmer (heck, you're ahead of most) :)

Don't sell yourself short.

GFischer··on Type 2 diabetes: NHS to offer 800-calorie diet treatment
I'm also interested (about to start my own diet but I hate non-varied diets). Any fasting method worked better than others?
GFischer··on Payless Opened Fake Luxury Store to See How Much People Would Pay for $20 Shoes
Paywalled. An interesting exercise in how much value branding adds though.
GFischer··on Ask HN: How do I teach my parents to use a computer?
I got my grandmother to use a computer, but she always used a few predefined paths.

Another elderly relative relied on a relatively inexpensive, patient tech support person (basically an advanced user). There was a cottage industry of techies helping the elderly in my country, maybe there's something similar where you live?

GFischer··on Incrementally adopting Istio for traffic management
I wonder how many companies actually need Istio. It's definitely for large scale.
GFischer··on Ask HN: Tips on how to get started in tech consulting?
Check previous threads about this. I'm not a consultant but it seems you already have a network to start.

This is something I saved up from here:

--

1) Produce publicly visible artifacts which demonstrate that you're able to apply technology to impact business outcomes. You do not need many of these; ~3 is fine. You do not need to block on the other steps. You do need to plausibly connect the technology to a business outcome; blockchain and beginner-level cryptography probably do not get you there.

2) Begin getting into conversations with people who either a) have purchasing authority or b) talk to people with purchasing authority, at your target clients or firms very similar to them. This can be as simple as bonding over technical things with technical people. You want to become Internet buddies with e.g. senior engineers / team leads / etc at software companies.

3) Walk the network of your new friends to engagements, either at their firms or peer firms. Do not make another WordPress site for the average business; make something for a software company.

4) For every engagement you land, attempt to get referrals to more clients, attempt to land follow-on work with the same client, and attempt to land ongoing maintenance/retainer/etc agreements with the client.

GFischer··on Ryanair, Hamiltonian Cycles, and using graph theory to find cheap flights
If you're interested, these slides are a cool introduction to the complexity of air travel:

GFischer··on Everyone is totally just winging it, all the time (2014)
They don't exactly advertise it. I remember Snapchat's founder (Evan Spiegel) was even weathier than Gates and Zuck (and that helped him resist buyout offers).
GFischer··on Ask HN: Can you recommend a modern, accessible P2P framework/library?
It's not entirely P2P, you need a server for initial connectivity.

But it's probably good enough for most P2P applications (I saw someone building P2P CDNs with it !!!)

GFischer··on AI Mistakes Bus-Side Ad for Famous CEO, Charges Her With Jaywalking
Some games (League of Legends, Ingress) have or had crowdsourced 1st level appeals for minor infractions.

Maybe that's the way to go. I know many volunteers answer Google's forums.

GFischer··on AI Mistakes Bus-Side Ad for Famous CEO, Charges Her with Jaywalking
A newer submission got traction, see discussion here: https://news.ycombinator.com/item?id=18527917
GFischer··on Toronto’s Tech Industry
I'm a foreigner with ties to Toronto, and I ruled it out. Salaries vs housing costs don't add up.
GFischer··on How a Tech Billionaire Created Two Fortunes and a Software Sweatshop
Adding to that: 15/hr is a decent wage in many countries, but you'll be paying at least 30 due to overhead and a middleman which will be the one really profiting.

And the middleman might bait and switch you on a 7/hr junior coder.

GFischer··on Ask HN: How do you deal with or improve software development estimates?
It depends a LOT on what you're estimating.

Estimating a CRUD line of business app is very much doable. On the other hand, estimating an innovative product using unproven tech or novel methods requires a proof of concept before even knowing feasibility.

I worked with major consultancies, and the most serious gave you order-of-magnitude estimates, with iterating improvements on the estimation itself until you reached a +/- 15% estimation that was the best they could do.

Very similar to: https://www.construx.com/software-thought-leadership/books/t...

In those cases, it was a very reasonable estimate because they'd done very similar things before.

One of those consultancies used an tool and they had measured their teams' velocity and were very confident on their estimates.

For one of my own projects, we had to estimate a rewrite of an existing app (with slight improvements), which is as easy as it can get in regards to estimation. We used several approaches, the one that ended up being closest to reality was Steve McConnell's tool Construx Estimate (no longer available but you can find a mirror here: https://web.archive.org/web/20170920093850/https://www.const... )

GFischer··on Agile won the war but lost the peace
I loved an estimation tool called Construx Estimate, by Steve McConnell. The few times I used it it was far more accurate than the other estimation techniques we were using at the time.

GFischer··on Google's interview system: it's not about solving the problem
Definitely a bad fit for Google, they aren't especially well known for caring about user experience or the user these days... (/s)
GFischer··on So You Wanna Be a Chef (2010)
As someone who paid for a non-top MBA and regrets it, I agree with the grandparent - don't take a (non-top) MBA unless your employer is paying (and don't take the top one unless you know what you'll do with it, though connections will be very sweet).

If you can get into Wharton or Harvard I think it's very likely someone other than yourself will be paying.

GFischer··on Bill of the Month: A $48k Allergy Test
I've worked in insurance for almost a decade (P&C), and I believe what the U.S. calls "health insurance" is a travesty.

"Insurance is a means of protection from financial loss. It is a form of risk management, primarily used to hedge against the risk of a contingent or uncertain loss"

Insurance should never be used for something CERTAIN and inelastic such as healthcare. For specific health risks, sure, but for standard care? It makes absolutely no sense.

I don't know how the U.S. can fix its healthcare crisis, but it's an absolute disaster. Other countries don't have 48k allergy tests.

GFischer··on Ask HN: Is it just me, or are fake callers getting out of control?
I got a job at an U.S. company and so I now have a T-Mobile phone as well as my Uruguayan phone.

I've never gotten a robocall on my Uruguayan phone and half the world must have it on their database (Spammy SMS, on the other hand, are a problem).

OTOH, my U.S. phone gets several calls a day, and I've seldom given it out. Most are marked "Scam Likely" by T-Mobile. But I've never gotten a spammy SMS.

A surprising cultural shock, to be sure.

I simply don't answer the U.S. phone anymore.

GFischer··on CEO Shoots Self to Test Bulletproof Jacket
Heck, president-elect Bolsonaro got stabbed campaigning in Brazil.

I'm not sure if current presidents use bulletproof clothing.

GFischer··on Bill of the Month: A $48k Allergy Test
Not the OP, but this is a Big Thing for me too (and I'm from Uruguay). I am aware of a lot of other differences, but I don't see that many other things that I'd care about.

And I've been to middle-of-nowhere, USA and have family there so I know it's not a bed of roses, but you also don't fully realize how good you have it in many other ways.

GFischer··on Winamp 5.8 Release – First update in 5 years
iTunes used to be extremely crappy and noxious on Windows, I wonder if it's changed.

I'm STILL using mainly Winamp. I've tried some alternatives but for my old MP3 collection it's unbeatable.

GFischer··on Ask HN: Founders, what is the worst experience you had with developers?
I've worked with tremendously good Indian engineers as well. But in most cases they were already in the U.S. on some kind of visa, permanent residents or citizens.

I have had good experiences with outsourcing in India itself as well, there are some serious teams there too. But there were some bad cases as well.

Money is definitely an indicator of quality, expensive might not mean good but cheap almost always means they're not top talent.

GFischer··on The highest paid workers in Silicon Valley are product managers (2016)
Here in Uruguay if you wish to call yourself an "engineer" you need to have an accredited engineering degree.

There is a career called C.S. Engineer and it has an huge amount of math and physics (equivalent to an undergrad + master's in the U.S.). Most of us take the career that's equivalent to an undergraduate degree though, the extra math (and grueling attrition) is mostly useless.

But graduates are very sought after because they've proven themselves able to go through a tough grind (even though they don't have a shred of practical experience after graduating)

GFischer··on How I hacked modern vending machines
I remember my mind being blown when I saw a newspaper dispensing machine in Canada for the first time...

That would absolutely not work in South America.

You can clearly see which tourists are from our part of the world in Europe where paying for transport is "optional"...

GFischer··on Ask HN: If you are 30+, what advice would you give to your 20-something self?
Don't get into debt. Manage your finances carefully. Exercise more and eat healthier. Learn to cook.

I can't stress the part about debt and finances enough.

GFischer··on Ask HN: How to avoid TV addiction?
I'm also having similar issues. I was recommended Cognitive behavioral therapy. I'm also going to have a doctor's visit.

They always recommend exercise, so I agree with DoreenMichele's advice. I'm overweight and have poor fitness.
