I used to follow a lot, and drank a bunch of the kool-aid from Jigsaw Trading. Now I read very little, other than the economic calendar for US/Canada/Europe each morning. I'm looking for high volatility events(such as FOMC, GDP, etc) so I can make sure I am not in the market when they take place.

I haven't read any books about algorithmic trading(but I've read a ton about trading in general...favorite is Mark Douglas's 'Trading in the Zone'). Most of my introduction to algorithmic trading came from a trading platform(Multicharts.NET). I wasn't a .NET programmer specifically, but they include the source code for all indicators/signals that ship with the product. This made it really easy to tinker with automated trading signals, and I don't think I would have ever attempted it without that exposure.

Also, you didn't ask for this piece of advice...but: be very cautious of tips from any blog or news outlet. The people producing those are under tremendous pressure to produce "something", even when there isn't any insight to be had for a day/week/event/etc. They will produce something anyway, relevance be damned. If you needed some help/ideas, you would be better served joining a live trading group. Many of these are free, and they give you a chance to listen(and speak) to other traders, all trading at the same time, usually with the same instruments. I learned some things from GPI Trading Group(http://www.gpitradinggroup.com/) that saved me a lot of time and headache. They are focused on the ZB(bond futures, not equities), but back at that time so was I. I got a lot of feedback from their members about my indicators and automated signals I was working on, and much of it was invaluable.
> Your dismissive attitude towards this is antithetical to the design of user friendly software

And your dismissive attitude of the project's own design goals is antithetical to the notion that not everybody has the same priorities as you, nor do they think your personal ideas equate to "the design of user friendly software".

The principle of "no surprises" is probably the greatest aspect of "user friendly software" when it comes to power tools such as shells, scripting languages, programming languages, etc. and that seems to be what GP is stating as preferable to edge-case scenario surprises.

You may disagree all you like with that as a priority, but please don't go to the extreme of stating that someone is being dismissive simply because they don't hold your idea up on a golden plinth above their own.

Well, the article is just stating the truth, that is the deficit is going down mainly because public investment in that last few years is being almost null (mainly in infrastructure) and now Portugal can go to the markets after seeing removed the "trash" title from the public debt. (Not) The only problem is that a big part of Portugal's infrastructure is starting to be outdated and should have have been renewed.

The actual government is mainly taking advantage of tourism growth and the stimulus from the Central European Bank (https://www.ft.com/content/7514a734-6fbe-11e8-92d3-6c13e5c92...) and is selling the recent growth as being a consequence from their measures of lowering taxes (which is not exactly true, also - https://www.pordata.pt/Portugal/Receitas+fiscais+do+Estado+t..., and yeah I know that if more people have a job more the total amount of taxes collected is higher) and others.

Being a Portuguese living in Portugal, it is obvious that the economy is improving but that improvement is not sustainable IMHO.
While I totally agree that the Wright Brothers work was amazing and ground breaking, their engine was not. It weighed ~180 lbs. (was the heaviest single thing on the airplane, heavier than either of the brothers- if you look carefully you will see that the pilot is a bit further from the centerline of the aircraft than the engine is, to balance out the weight) and produced 12 hp (the spec said <200 lbs and producing > 8hp, so it was better than the spec). Samuel Langley, working on his own engine for the failed full-sized Aerodrome #5, had an engine that weighed <210 lbs but produced 52hp, more than 4x the power. But the Wright Brothers fabulous propellers (seriously, today, with 115 years experience building airplanes, fancy computer modelling, etc., we can build a propeller out of wood about 3% better than the ones the Wright Brothers built) more than made up the difference. Because sometimes good design beats brute force.

I just don't understand how people in HN of all place complain about the costs of healthcare. I believe America has a better system, especially if you are in the hacker mindset (and with IT salaries!). Just fly to wherever, and get treated for a great price and quality.

And that's not specific to the US. I've heard Eastern Europe provides great dentistry services and that even Western Europeans fly there to get treated.

Couldn't you mill a PCB a lot cheaper with a 3 axis machine?

yea ... but thats really their purpose. And even in a logical sense the company itself should strive for such measures. Learn where you "can" outsource then do it.

The thorough process and underlying principal isnt bad. Its the execution here that really caused the problem, choosing a provider not as reliable as their own.

Same thing could happen in house. Manager comes in decides to cut cost , sees redundant employees, decides to reduce communications engineers by half. Same problem.

What kind of crappy car do you have that requires removing the bumper?

Mine isn't the easiest in the world to change bulbs on, but it's not that hard, as you just have to pull out the fender liners a little to get to the bulbs. But with HIDs, I've never needed to do that, and likely won't for years to come. I guess paying extra for HIDs ends up paying for itself...
It's interesting to apply these findings and conclusions to other areas.

For example, Bitcoin is a lot like the interstate highway system in that it's prone to traffic jams. The Great Bitcoin Scaling Debate of 2016 and 2017 attempted to address this problem

One camp argued strongly like the old-school urban planners in the linked article: more capacity = less congestion.

Another group argued that variable-rate fees (a feature built into Bitcoin from the beginning) would take care of the problem. When transaction volume spikes, so do fees. This discourages use during spikes and incentivizes off-peak use.

Bitcoin ended up adding a small increase to capacity in the form of segwit.

The result followed the prediction in the article. After a massive spike in usage during the later part of 2017, fees spiked to $50 or more per transaction. This was followed by a marked decrease in on-chain transaction volume to the point that blocks aren't full today. Fees have likewise decreased by more than two orders of magnitude.

Two other developments during 2018 may be relevant:

1. The BTC/USD exchange rate collapsed.

2. The Lightning Network (a way to route more transaction volume with fewer on-chain transactions) was deployed on mainnet.
No, inefficiency does not boost the economy. That spending would get allocated more efficiently otherwise which should actually be an overall boost to the economy.
Is this even a problem? People are given an opportunity to do something and then they do it. That's way better than new roads going unused, isn't it?

I've never sat in stop-and-go traffic, looked around and thought "Gee, this is great utilization of this road!"

Oddly, I have looked around a crowded standing-room-only train and thought "Gee, these load factors must be good for farebox recovery"
The cultural problems are definitely the more problematic ones. My kids run around the neighborhood, but they do so nearly alone, because nobody else's kids are allowed the same freedom. I'm hoping that once the other parents see that my kids haven't been killed by a roving serial killer then they'll let their kids come out too, but there's not much I can do beyond that.
> I’m surprised political speech is not protected specifically as it is in the UK and Australia in France for example

It is protected. It's just that hate speech is an explicit exception from that rule (which is the whole point of that designation). Most of hate speech is political in some way.

So it all boils down to who gets to define what is "hate speech", exactly.

> I still don’t agree the trade off for Nazis is worth it.

What trade-off? Neo-Nazis flourish in the very same countries that have extensive censorship of their ideologies and speech. Look at Germany with their "streitbare Demokratie" for an example - they don't just censor speech, they outright ban parties solely on the basis of their platforms. And for those efforts, they get yearly neo-Nazi marches that are several times bigger than the one-off we've seen in Charlottesville, and AfD is now the second most popular party.

On the other hand, there's this trade-off:

Of course, arithmetic is a somewhat silly example, because we generally tend to have arithmetic built in, and we all know how arithmetic works.

"Refactor to remove duplication" is absolutely a standard step of TDD. How you do it is up to you. This is not an automated process, it requires (design) skill and good judgement just like any other programming.

I recall once seeing Beck look at two loops that were quite dissimilar: they had different for structures, and different contents, which is pretty much nothing duplicated except the word "for", and the fact that they were looping - differently - over the same collection.
He changed the second loop to loop the same way the first one did. This required changing the body of the loop to skip over the items toward the end of the collection, since the previous version only did the front of the collection.

Now the for statements were the same. "Well, gotta eliminate that duplication, he said, and moved the second body into the first loop and deleted the second loop entirely.
Now he had two kinds of similar processing going on in the one loop. He found some kind of duplication in there, extracted a method, did a couple of other things, and voila! the code was much better.

What this approach does is move most of this type of tricky design work to a phase of development when you are not also trying to figure out what the program is trying to do or how to do it. Instead, while you are doing this design work, the behaviour of the program remains fixed and you have tests to make sure that's actually the case.

Having the code remain functionally identical (in terms of the tests) is a lovely safety net to have while you are doing fancy coding acrobatics. If you find you're in a dead-end, revert, check that the tests are still green and try again, with the knowledge you've just gained.

I guess this is something that older developers are more attuned to, because they have been humbled by code enough to appreciate the limitations of their cognitive faculties.

> rejecting your judgment

I trust my judgement, always, and am wary of my judgement, always. But I also listen to the code, and I just don't "remove duplication" until there actually is duplication.

> Is it down to the fact that there is simply more "freedom" with regards to roads over rail?

Yup. I live in a metro with the longest light rail system in the US (almost 100 miles) and I don't go anywhere near one during my commute and many don't. It doesn't get half the riders that the second-longest gets. I would not vote for light rail funding...different strokes and all that.
Thanks, I will read. And hopefully I will review. Hope I can hold myself accountable to that.
Some airports also have public phone numbers to get weather information, could come in handy to know if you're-for example, living in tornado alley and a system rolls through that knocks out power and cellular service.

If you have a working landline phone, calling a nearby airport could be your only way to know the latest conditions and if it's safe to go outside.

There's just one encoder per joint. The encoder disk is 3D printed and the cruft from the print is used to refine the encoder ticks. Instead of fighting noise they save a map of all the systematic noise and then can use a lookup table to localize.

Our sucess boils to a tourism increase (driven from political instability in other countries and a very laxed tax system for foreigners), cheap oil (that gave room to increase taxes on petrol) and historically low interest rates.
This is dealt with in the article - debugging optimised code is a pain, even when you know what you're doing. The source-level debugging often doesn't work, variable watches often don't work (and this even though DWARF has a whole pile of features specifically so that this stuff can work...), and debugging at the assembly language level is a chore.

That's what I am saying. People keep supporting parties and not issues. If the Republicans make an 180 and support single payer their supporters will suddenly love single payer and Democrats will be skeptical.

I think the ability to get to the parks and fields without parental intervention is important in itself. I live in a neighborhood in Sydney where many of our streets are traffic sewers that people blast through at amazing (relatively speaking) speeds. As a large, visible adult, I walk the dog every day and 1-2 times out of 10 some idiot on a street 50m from my house doesn't know what the rules on a crosswalk are. People love to go on tirades about helicopter parents but given the quality of driving (also something that seems to have taken a hit from "Internet and smartphones") they haven't spent too much time thinking about the implications of what it's like to be an impulsive kid who will be mostly invisible stepping out behind a car, in a world where a lot of drivers are impatient and distracted.

There's a huge change in the vibe of having older kids (who can, despite the roads, go out and freely interact with their peers) and younger kids who aren't sensible enough to deal with the streets (and yes, this isn't just paranoia, we had a couple bad incidents in the peer group).

It's not an either/or with the Internet/smartphones, either. I think there's a lot of interaction between these factors ("kids go out less because games/internet are so compelling" vs "kids spend long hours on devices because they are stuck at home") in both directions.

How does anything about the way medical care is administered in the US work in the context of the mythical "free market"?
Well... a whopping 45% of Americans have no access to public transit[0], in any form. So I would hazard a guess that those with access to light rail/subways is significantly less than 45%.

Light and commuter rail ridership makes up only 300M/quarter riders out of a total ridership of 2.5B/quarter for all forms of mass transit, if I'm reading this right.[1]

Counterpoint: I grew up in an area which allegedly has some of the worst roads in the country. They're fine. Sure they're not silky-smooth surfaces ready for MotoGP but contemporary mass-market vehicles have no problem traversing them. At worst you're going to feel uncomfortable for half a second. Really bad construction might slow you down 10-20 minutes.

Meanwhile America's best, most expensive, most politically supported public transit systems barely work, and can be expected to fail you completely several times each month.

The lived experiences don't match the theory. Roads usually work fine, and degrade gracefully when they don't. Transit is obnoxious on a good day, and when it fails it cascades catastrophically.

I want to be a good urbanist, but the quality just isn't there, nor does it seem to be a budget priority (instead new money goes to fare subsidies, empty bus routes, etc).

The context is streets without cars any cars at all though.

Even in areas where there's a car occasionally, as kids we watched out for cars, not the other way around. We never assumed a car would brake for us. I'm sure it happens, but from my memories, not even the most reckless kids did that. And we did some shit, let me tell you :D

CenturyLink is critical to 9-1-1 services throughout the U.S. They have a 9-1-1 division to which a very large number of municipalities outsource. Even military installations outsource parts or all of their 9-1-1 operations to CenturyLink.

This CenturyLink division has historically acted very carelessly in regards to securing these systems. Getting them to take ownership of their contractual obligations can be difficult.

Criticism of their operations is very sensitive. Pointing out any vulnerabilities can be prosecuted as an act of terrorism. A post as simple as this one comes with significant risk.
Same with Australia. I live on a street that is also needed for emergency vehicles of most kinds as a primary route, so is just that bit wider, and you can see how ordinary motorists respond to this "incentive".
I swear the swiftness with which people swoop into these kinds of threads to suggest crypto/blockchain is bordering on becoming a meme.

If the network is fully down, I don't see how the scenario for this business owner changes with blockchain, they'd have the exact same problem with a register that can't close an ACH: backlogged transactions that need to catch up eventually, meaning some card types are going to decline if the POS can't reach a clearing house utilized by the card vendor.
FYI, these kind of beliefs surface mainly when people engage in groupthink. Few individuals actually believe these things. The vast majority believe in helping each other, but they prefer to help voluntarily rather than forcefully. Helping forcefully is often seen as a loss of freedom. Individuals are often OK with that loss of freedom, even though it hurts.

I hope that perspective helps you in your future discussions. :-)
This started out being a reminder list of software tools and languages that I'm currently using, evaluating, or have used and then it sort of morphed into a short list of what to consider using on new projects.

I'd like to add any major omissions to this list. There are certainly things listed that are specific to my historical use and will get removed to make it into recommendations.

I'm trying to keep the list forward thinking as well as short so when there are multiple similar items choosing one where I have an opinion (e.g. Clojure rather than Racket/Scheme).
