It likely was happening.

If I'm a market-maker, I want to trade with retail orders or slowly sliced institutional orders that are trying to rebalance a portfolio throughout the day. When I sell stock to them, the price doesn't move very much in the short-term and I have a chance to buy back on the bid to make a spread. I don't want to trade with aggressive arbitrage or stat-arb traders capturing short-term price inefficiencies, hedge funds that want to buy huge blocks of stock all at once, etc. If I sell stock to them, the price ends up moving up more than the spread very rapidly and I lose money.

When trading on a public market, I have no way to control which of these groups I trade with. I have to employ countermeasures to predict whether it's likely that I'll trade with an informed or uninformed trader and adjust my market accordingly. This is why you see market-makers rapidly flash their quotes for seemingly pointless reasons (e.g. I may adjust my prices in an airline when oil futures move) or flip out of positions aggressively when their model believes they were hit by an informed trader.

Now if I'm able to trade on a market where I know I'll only trade with long-term fundamental traders, I can quote much larger, tighter, and more stable markets. This is good for the institutions since their execution costs are lower than going to the exchanges. It's bad for arbitrage traders and hedge funds with short-term information since they effectively pay higher execution costs in a tiered market (if more "good" order flow goes to dark pools, less reaches displayed markets, and spreads on displayed markets will increase to compensate). When people want to end dark trading or internalization, they really want to have retail and institutional flow cross-subsidize fast speculators.

Ironically, it's probably HFT market-making firms who were the most impacted by Barclays giving other high-alpha HFT firms manual overrides to put them in a lower tier. If anyone would be excited at the promise of removing high-alpha traders from the pool, it would be market-makers who want to avoid being "picked off", not institutions who have a much longer time horizon.

Well, that's hilarious.
What they care about is irrelevant, they are also alienating creators of apps that make them money with this kind of attitude.

They are basically repeating the same mistakes Jobs made two decades ago which led to the almost bankruptcy of Apple. Granted, they have enough money in the bank to be safe from this, but this kind of behavior is simply accelerating the decay of their market share, and as a consequence of that, of their profits.
Sounds impressive. Do you have a pre-existing product database that you match them up to or do you just create products on the fly?
Nothing of that nature was implied; rather, you read misogyny into the comment due to your own biases.

The original post was very careful not to put either sex in either role. It even went so far as to not exclude homosexual relations by suggesting that you'd want three people in the room despite a segregated workplace.

Your post, in contrast, insists that harassment suits are always filed by woman against men. It goes so far as to suggest these hypothetical employers must be men and that their motivation is an inability to control themselves.

The implication was simply that as sexual harassment cases become more costly, it may be pragmatic to take more drastic measures to prevent them. I'm very disgusted by your post.
Ask HN: How do I get more side work?
How can I improve my lot, for side work?

TL;DR - I'm doing desktop support and break/fix stuff to earn extra income, and need more customers. Would like to do as much remote as possible? How do I get more customers?

I have a pretty good paying technical day job already. A couple years ago, I made some poor decisions that got us into some debt. Some necessary, some not... but it's still painful. About $24K of debt, in total.

Since I'm not a programmer at this point, I don't have the higher earning power like programmers do.

I can do sysadmin and break/fix work though. I'm comfortable on any platform, and would much rather be doing Linux/UNIX work, but most of my work is Windows-realted, by virtue of its market share.

My question is... how do you get extra work for stuff like that, when people who have those skills are a dime a dozen? Thus far, I've been doing break/fix work, and troubleshooting desktop issues - to earn some extra money.

I've been charging $75/hr for this work. Should I be charging more? less?

I am working on learning Python, so that I can increase the services I offer to customers, but with a day job and this side work, my efforts are slow going. I know I could earn more as a programmer, but it's going to take some time to get to be able to do it on a paid basis.

I appreciate your help.

The real cure for Imposter Syndrome is objective, hard data concerning a) something real world that you are trying to accomplish and b) your actual relative ability compared to some social norm that matters for the ability being measured. The issue with Imposter Syndrome is that "social proof" is often not very good proof. There are forms of social proof which can be valuable but they are also often painful (a al Bill Gates quote about "your unhappiest customers" being your best source of learning). But a lot of that "rah rah, we think you are awesome and will thus kiss your butt and not give you meaningful feedback" stuff is something to very much worry about.
In your blog post, you argue that since the two terms result in (mostly) the same output/outcome, the two terms are synonymous. However, according to FSF's open-source/free-software overlap diagram [1], tivoized programs are open source but nonfree, meaning that there is a difference between the outcome of the two terms.

More importantly, that difference is actually a big reflection of the underlying philosophy between the two terms. Free software is about maintaining the Four Freedoms (making tivoization a damaging loophole in the GPL), while open source is about arguing that the bazaar model is superior technically in order to sell it to business (and therefore tivoization is actually a plus to them). I believe this difference in intent should be noteworthy to the IRS in terms of evaluating whether a company is creating a nonprofit for tax-free software development as a form of corporate welfare.

Yeah, but the point of Go is to be minimal and easy. Basically, this makes it really hard to be clever. In both senses, unfortunately, but I see how it can be a net win for big projects.
How would NO-IP detect C&C servers aliased to their subdomains, even if they connected to every single one of their subdomains daily -- they wouldn't know what ports to scan. By my, possibly naive thinking, they'd have to impose denial of service attacks on their own customers, constantly, and they would be easily thwarted by port knocking schemes. Probably their only recourse is to stop offering free service, and instead take payment, or require and verify customer IDs. I'm not sure there's a technical solution. Microsoft seems to be attacking their business model.

Call me naive, but when harrassment this egregious is exposed at a well-known tech company, I don't feel the need to stroke my chin and wonder if there's a media conspiracy to make it appear worse than it is. I don't even know how this could be made to look worse than it is. What possible spin could a publisher put on this that is not already present in the allegation and evidence?

Thanks, that clears it up a bunch.

All of those things are being built yet, so we don't have much to link to. There are a few work-in-progress things, for example, the postgres adapter is coming along, and rust-graphics for graphical primitives. As we get closer to release, and as they mature, we'll feature them more.

> Will the cross-platform components from Servo be included in the Rust standard library?

As we already have a package manager, I think Rust will tend to have a smaller standard library, and encourage its use more. We'll see though.

We support Windows, Mac, and Linux as first-class platforms, and every pull request (and additions are all through pull requests) is tested on android. iOS coming soon.

Then release/sell a library. Don't expect Bitcoin users (who, especially the early adopters, are almost tautologically more likely to distrust centralized services). Library code can be audited, and guaranteed to do what it advertizes.
I work on protocol engineering and one of the protocols I support requires fields to be padded at 4-byte word boundaries. The code I inherited uses a grungy macro to solve this problem:

#define WORD_ALIGN_LEN(l) (l % 4 ? (((l/4)*4) + 4) : l)

So for all you complaining about his solution being difficult to mentally parse: it could be worse.

(Our code will divide by 4 and then multiply by 4, truncating the remainder, and then add 4. So if we're sending 6 bytes, we'll divide by 4 to get 1, multiply to get 4, then add 4 to get 8.)

I should have differentiated between "open source hardware" and open hardware. By using the later term, I meant to describe hardware that uses open source software to drive the hardware, and that can be easily modified.

If I were to use a word, personally, it might be "daunting" instead of "terrifying" but I have at least some experience with C and manual memory management. In that regard C isn't alien to me, so my perception is a little different from the op.

I don't think the parent post was trying to say C++ was necessarily bad, but the features of C++ being justifiable or not don't really impact my feeling of it being daunting, or terrifying to learn. I could say, with reasonable certainty, that every part of a space shuttle launch probably has a good reason for being there, but the system taken as a whole is still intimidating. It's that C++ is a huge beast and there's just so much there. I haven't gone hard core at looking into C++, but every time I do people start of by saying you need to pick a sane subset of the language to work with, and they all have different views of what is and isn't sane. Add to that the fact that you can do some potentially scary stuff when you're close to the hardware, and I can see why it would be a bit scary.

In my view, the right way to approach that, if I were really trying to learn the language, would be to just pick a guide and go with the assumptions it makes until the reasoning for those assumptions becomes more clear and I can better pick and choose according to my use case. But it's still an intimidating proposition.

I'm also guessing that something like Javascript is less terrifying because of previous experience with dynamic languages. The kind of foot-shooting you do in javascript (because of accidental global scoping, poor equality semantics, or any number of things) at least make sense in the context of having programmed in a dynamic, managed language previously. C and C++ can be pretty scary when everyone talks about manually managing memory or being close to the metal or saying stuff about 'systems programming', which just sounds like crazy voodoo if you don't have a point of comparison.

I think the things your saying are all true. Just trying to offer my perspective as to why, those things being true, a language can still be scary to approach. fwiw
MeetMe - New Hope, PA (near Philadelphia, Pennsylvania) - http://www.meetme.com

We use a wide variety of languages, generally using what makes sense. C, PHP, Python, JavaScript and Node.js, and native iOS and Android development are the most common.

MeetMe is a fun place to work. We hold a yearly developer retreat, as well as regular company-wide hackathons. We have a book club, board game club, and we even have a game room. While we aren't a new company in the time scale of the internet, we still know how to have fun. We just get the benefit of not having to kill ourselves working 12 hour days. =) This means you'll enjoy actually going home on time! We have many openings, both technical and non-technical. Here is a list of positions we are usually always looking for.

* Senior Web Developer

* Senior Android Developer

* Software iOS Developer

The way I compute the variance above is, to my knowledge, the standard algorithm implemented by most software packages (apparently including MATLAB). (The single pass computation you mention is subject to catastrophic cancellation, and thus pretty terrible unless the mean of your data is very small relative to the variance.) However, the "real" implementation in Julia standard library is indeed a bit better: it performs pairwise summation, which has O(log n) error growth instead of O(n) error growth at negligible performance cost (see http://en.wikipedia.org/wiki/Pairwise_summation).

The cars young people drive are usually cheap and old (potentially hand-me-downs from their parents or older siblings) and they only have liability insurance, but it is possible for a lot of people.
