Most of what I'm doing is systems engineering. Incorporating research and code from others. Reporting and occasionally fixing bugs. The research in this case is primarily coming from Google. Linux has the state of the art TCP stack at the moment, but for various reasons (http://www.bsdnow.tv/episodes/2018_04_11-bowling_in_the_lime...) we run FreeBSD. So the other part is re-implementing things on that. I am individual contributor on the main body of our code, I directly recruited and hired my team, and sought out and set up contracts to get features like TCP Fast Open done (with some particular twists that make sense for our workload). In an industrial setting, it is both competent and desirable for most companies to be in this kind of engineering mode (application of existing technology).

I'll give this simple example as a call to action. Schedulers of any kind, say the one that puts threads on to CPUs, are open-ended problems. If you co-design a system with hardware and software, it is highly likely you can get a 20% speedup in a system by manually emplacing different workloads (i.e. NIC interrupt handlers, application threads). In TCP, this same kind of thing applies. If you run Linux, there are a lot of things in the Documentation/ directory of the kernel that are worth reading and tuning. Selecting a congestion control, and tuning buffer sizes is very much "working on TCP" and could benefit any company using TCP. It's also something anyone with a few years of general development experience shouldn't feel intimidated to do! The most critical skill isn't any particular technology but learning to measure and confidently make and deploy changes. Likewise, there are very few things on computers that can't be improved. This can range from tuning general settings to a particular workload or change of underlying hardware, to algorithmic advances.

Yeah it's definitely not a big issue that this is commited under Anonymous Coward since you know the decision was made by Google to axe this and it would matter very little which engineer specifically removed these lines of code.

Embryos at the stage before you implant them into a womb are not human beings.
Eugenics has two side - discouraging certain people to have fewer (or no) children and encouraging others to have more. We seem to be obsessed with the fewer side and don’t look much at the more side.

The most powerful eugenics force in history is the modern education system. It is extremely effective in identifying those with high levels of abstract reasoning and strongly discouraging them from having children. Gets very little attention outside of documentaries masquerading as comedies.

Snowden has certainly paid a price for his leaks. However, the Washington Post, New York Times, and others were not punished for re-publishing or discussing the content of these leaks. Historically, American papers have successfully defended their right to do so in court (the Pentagon Papers, Watergate). Leakers also do often maintain anonymity, obtain legal protection, or receive pardons when their leaks appear to serve the public interest (Daniel Ellsberg, Deep Throat, Manning). The situation in China for newspapers, journalists, and sources is far worse.

Manning, by the way, leaked an enormous unredacted cache of documents pertaining to active, ongoing military operations. This leak very likely resulted in the deaths of anti-Taliban and anti-Islamist informants and cooperators. Not all leaks are good at all times for all people, and some confidentiality rules exist for good reason.

But, if you're a nation state, I'm sure just throwing money at the open market will work too. I'm sure that for every company that refuse defence contracts, there are a number that will hapilly build a pink fluffy-looking drone with built in facial recognition, 250 grams of explosives and a proximity fuse. Or, just be willing to sell surveillance tech to authorative governments.
Arguments (1) and (2) run counter to both academic investigation[1,3] and industrial consensus[4,5]. Outside of IEX and its affiliates, you don't really find mainstream criticism of HFT from authoritative sources.

As a particular point of contention: most academic studies of the subject find that HFT activity has significantly improved liquidity and price accuracy across e.g. equity trading. But at the same time, HFT as an aggregate industry is both tiny and shrinking. Despite accounting for nearly 60% of equity trading volume last year, the HFT industry had aggregate revenues of ~$1B[2]. So no, it's not a net wealth transfer from investors to HFT firms, and their (ostensibly positive) impact is dramatically outsized compared to their activity (this is aside from the fact that HFT activity is virtually imperceptible to retail traders anyway).

As a meta comment, I think you should reexamine your assertion about what would happen in a "fair world", because it's game theoretically vacuous. Under your paradigm, how does price discovery function when informational and temporal asymmetry are eliminated? How would the market exist and accomplish its functions in a way substantially similar to the way it does presently?

Stated another way, what "fair" advantages would you allow market participants to compete with that are not already a function of information asymmetry or speed?

Your argument presupposes that there is some constant per-share price to be paid for a piece of bad news, when in fact it is the function of the market, through trading, to arrive at a consensus valuation for that news.

Hmm the issue is that there might be some correlation between the syntactic and lexical similarity and the actual subject matter the authors are talking about.

I've been working on a similar project.

Three things that I would suggest would be

- add documents definitively written by the authors (Maddison, John jay, etc) from outside the federalist papers to your train set.

http://oll.libertyfund.org/titles/jay-the-correspondence-and...

http://www.gutenberg.org/ebooks/author/14, etc

- Add another feature which looks at the frequency of the function (closed class words) such as articles, prepositions etc these are very stylistic and hard for an author to control, they are also independent of the content, this is a classical feature in forensics.

- Add a distractor case to your train and validation set I.e documents written by a non federalist such as Thomas Jefferson and confirm that they don't get clustered into one of the other federalist authors.

If you have questions feel free to tweet me it seems like a cool project @pythiccoder

:) there are a lot of awful managers in tech, I tried hard not to be one of them.

A good first level manager in my opinion should remain a strong individual contributor to the team. It's important to have prudent knowledge of the system and continuously develop your decision making basis. On top of this, a good manager should be directly recruiting and hiring talent (i.e. talent agencies and recrutiers are not good ways to build a team). And you should finally and most importantly be an advocate for the individuals on your team (compensation, basic empathy around life events etc) and the output of the team (vendors, other teams, etc will eventually try to undercut you knowingly or not. If the work is meaningful, and you are doing well, you must generate positive news about it). Done well, it's not an easy job.
Ugh the Numba claims. It still has a high function call overhead from Python and is type restricted. I couldn't pass functions to SciPy ODE solvers without a 10x overhead of doing things directly in Julia and C++, so while a ton better than straight Python it was still bad.

Also there are very few packages actually using Numba. It seems that more people like to talk about possibly using it than actually use it.
In what ways would that proposal be more efficient than continuous trading?
I discovered Christopher Alexander by accident.

When I was a student, my free time was spent in dusty corners of university libraries digging up old, forgotten books. I found many gems this way (including the venerable TAOCP. I only realized how famous it is after reading the Wikipedia page).

Although he seems to be most famous for the "Pattern Language" book, my introduction to his work was during my visit to the university's architecture library, from a slim volume entitled "Notes on the synthesis of form". It really highlights the magnitude of the task facing the modern architect/designer/developer. The first half of the book details how for most of history, design has not been a conscious process but rather an emergent property arising through a selection process (basically evolution). The alternative, discussed in the second half of the book, is for a human to sit down and think through the requirements and design almost de novo - this is extremely challenging due to the number of interacting variables.

Reading this book gave me a much better appreciation and respect for evolved techniques (eg. traditional methods of building, farming, etc; even social norms and traditions), and gave me valuable thoughts on when an evolutionary approach would work better vs a design approach (similar to Linux's explicit evolution vs OpenBSD's considered design).

I was a bit like you... struggled at university, failed plenty of topics (some twice) because it never "clicked". I fluked a job at a small company and turns out I'm pretty decent with people & understanding what people want/need. I got by with my code, but it was elementary if I'm honest with myself.

For the past 14 years I've run my own web dev company but I understood my limitations and hired people who are actually good at coding and I've stuck to what I'm good at.

From what you write, there doesn't appear to be a passion for coding - avoiding assignments & now struggling with core constructs point to that. But something at some point got you into this field - perhaps there's something to the side that might suit your skills/passion more? Testing, QA, project management, client management, business analysis... there's lots of roles that benefit of understanding programming concepts that don't rely on you actually being a gun programmer.
Android has 75% market share, it's not like you can avoid it, they have practically a monopoly. As much as people like Apple here, it's nowhere near the same market share as Android.

Also you should put quotes around open-source, AOSP does not run on any real device due to a lot of android parts being private + private drivers. It took me one month to run a custom kernel on my Samsung to get the basic hardware working, it's as far as open source as you can get. Android is a "look but don't touch" kind of open-source.

It's never been otherwise. It's returned to a hard dictatorship from a soft dictatorship, and appears to be shifting from authoritarian to totalitarian. I'm not sure if Mao's rule is properly termed 'totalitarian'.
I spent all my money on a nv3 chip. It was so fast that it made games easy. I was used to precompute mentally every move because of low fps and lag. It probably also changed how physics were simulated in old games (lower time resolution probably introduced wilder results).

nvidia felt like an odd company, it was small and unknown, unlike Ati or Matrox. But their chip were cheap and competitive with champion 3dfx.

Still impressive how they stretched markets from toys to the highest sophistication.

I recently read a book about Commodore's downfall and it's clear that its disappearance was due to a lack of future vision and future planning in Jack Tramiel's part. He got lucky with the Commodore 64 and was looking for the next big hit. Rather than to develop the company while keeping its customers happy, he focused on short-term profits. He had no idea what to develop for the company's customers. So he hoped a new hit would save the company.

Commodore owned the market for home computers. Commodore's customers would have stayed loyal to the company if they could have gotten a product that moved the Commodore technology forward but they could not advance the technology. They saw sales decline and decided to find another hit rather than to advance the technology.

When he moved on to Atari he developed a great machine but he just did not know how to move forward the same way he did not know with Commodore.
I used my chip card in Canada during the last week. I used my visa chip card heavily for gas, bc ferries, food, etc. I remember giving out my card number, expiry date and security code to an agency that offers whale seeing tours in Victoria Island. Next day, I saw two charges: $108.XX from Chick-A-Fil, Salisbury, MD and $1.00 from Sweden. The card issuer called me right away to verify what's going on.

I wonder how my cc details were compromised. Was it a skimmer at gas stations? or one of those credit card scanners in Canada (Canadians seems to use PIN number with credit cards) or bcferries.com website.

I am not sure.

Pinpads and terminals have to be re-injected with debit keys for the appropriate bank and reconfigured with the correct software load & merchant account before you can use hardware that was used by another merchant. If you don't do that, the other merchant is very likely to receive the funds you charge your clients cards for, short of their merchant account being closed.

The reason EMV isn't enabled at most merchants is its both more expensive than standard swipe transactions, and massively slower unless your Costco & Kroger (who both just got quick chip). 30 seconds of waiting for a card to process, combined with EMV chip read errors due to partial insertion or failing/oxidized contacts (especially common on pinpads that aren't mounted to the table, most often the Pax S300 cause those customers are cheap AF) is a recipe for long lines.

Grocers are leading the EMV transition as they are the most powerful block of merchants when it comes to beating down interchange rates and processing fees, with Walmart repeatedly suing Mastercard, and other large retailers doing the same to the other card vendors. For that small segment, they've been able to beat down Visa & Mastercard on the per kilobyte data transmission fee and on the other BS fees that make processing EMV cards more expensive than magstripe.

The Himalayan state that declared war on plastic bags
Well, I think alexanderdmitri's advice of looking for answers to coding problems on places like Stackoverflow is great advice and I'd like to expand on it a bit.

It's easy to get sucked into a coding problem and fight with it for days like it's a personal challenge to your abilities. That can turn into a habit. It did for me. Screw that. Admit you have a problem and then get over it.

The goal of working is to produce something, and not necessarily, or even very often, to invent something new or even invent a new way of doing something. Coding is no different.

The truth is for most of us coding is more often akin to assembling something even when you're designing and building something new. That's how I approach it anyway.

When I switched from coding mainly Perl to Javascript I learned (the hard way) to start searching for answers first instead of banging my head on my desk for hours (even days) over what were often times really just syntax issues or things that already had boilerplate solutions publicly available.

Learning to search for answers first made a huge difference in my productivity and in how much I enjoyed coding. Getting stuff done provides a sense of accomplishment and we all need that to inspire us to keep working.

And it's made me a better coder too. I have learned so many new and better ways to do things, as well as how not to do them, and found great explanations on the "whys" and "hows" in the process. And I learn them when they're relevant to what I'm working on too, not in some abstract way that is easy to forget or dismiss.

The truth is there is way more to learn about coding than we can possibly learn already and that gap is constantly expanding. That's really a great thing though because learning on a need to know basis makes it so much easier to get stuff done. It lets us focus on one problem at a time and not worry about what comes after. We can learn what we need when we get there and by then there might be a new and better way.

When I first started making a habit of searching for answers and example code for how to do something I was amazed a few times to find an answer. Now I'm more surprised when I don't find one easily.

To me, that's what a "hacker" is in the truest sense. You find and write and hack together code. There's nothing wrong with that. It's why we have "open source" code and in fact it's truly awesome.
