First, let me make it clear, I don't view market participants competing on time as a problem and physics means it will always be a component of the price of the risk associated with trading. But if we are going to be making changes to markets, I'd much rather change the pricing requirements than adding esoteric random time differences, or assuming batch auctions will make things better.

The reason I like reducing tick sizes (and I mean dramatically like 1/1000th or more) is less about the bid ask spread at the middle, but rather the competition at the +1 levels. A lot of the latency advantage right now is in being able to cancel a few levels near the midpoint while leaving tons of other orders stacked.

Reducing tick sizes would make these deep stacking strategies less viable, which seems (though I have no proof) like it would make the positions of the market makers less risky in a systematic way.

As for GOOG vs MSFT, I think that is obviously explained by the much higher price of GOOG right? Nothing is going to make holding a stock that costs more less risky, even speed.

> She sets up a hosted blog so nobody has to actually maintain it.

Somebody has to maintain a Wordpress blog, keeping it updated and the plugin list pruned to reasonability. That somebody may be the end user, but a non-technical user maintaining a piece of business-critical software carries its own set of problems.

Someone years ago at my company solved this problem by integrating Wordpress into their own home-baked e-commerce platform. The platform wasn't maintained, Wordpress wasn't maintained, when I came in years later, I found a mess that wasn't even worth maintaining anymore. Eventually it broke. I refused to fix it and so we moved to hosted Wordpress just like Alice.

My solution would have been to find a Rails-based self-hosted blogging platform that I could integrate into my daily workflow. I told them I wouldn't be able to help them if Wordpress breaks and that Wordpress gets hacked all the time. I could have gotten it up in a single day, no big deal. No dice.

Company politics and strategy determine how productive a programmer is. Make him/her do stupid shit and they won't get much done. They say they don't want silos, but then all their technology decisions do is create silos.
9 out of 10 startups fail. While these odds are better than many other paths to wealth ...

That presupposes that a successful startup results in (the founders at least) becoming wealthy. That's a real stretch - unless you define it as "success". In that case, 10% is way, way too high.

If wealth is what you primarily want, you're probably in the wrong game anyway - and much more likely to fail than someone who wants to solve a problem.

These lawsuits expose a couple of things, one there needs to be more kinds of work classifications than employee and contractor. Two, the benefits system, healthcare, whatever, is still not fixed and has a long way to go to cover all citizens, regardless of employment type and status.

Another thing, is these platforms have more than one kind of participant, ones who utilize them as their main source of income, and those who utilize them as complementary source of income or as a part time/college/uni job.

If these platforms would simply be a platform (who like yelp) let the provider sink or swim based on ratings, then they could avoid the problems stemming from their requirements [which makes the platform less ad hoc and more rule based thus leaning toward employee - yet the fear would be a degradation in service to end users and thus a threat to platform viability]

The web components standards mostly deal with lifecycle and composition, not templating. One could easily not use a template system at all, or compile-to-JS template language like JSX, in a web component.

Looping and conditionals are often included in template languages because those are the most often used and most declarative control structures. More complex manipulations are left to code. This tends to work out very well in practice.
He has a point when you are talking about a large company. It is hard to extract the full potential of most 10x engineers in this setting. Difficult, but not impossible. Put those people in R&D or in some leaner group creating the next thing, not the current one. If what they make doesn't have a net positive impact then throw it away.

In a small startup the 10x'ers are critical. When you don't have a product sitting around and deciding what to build is probably worse than giving up. MVP it over and over until you have something. 0.1x'ers please don't apply.

At an average walking speed of 2.8mph, that's 4.6 hours of walking. The average American adult walks around 2.5 miles per day, mostly indoors trips between rooms. The American knowledge-worker or automobile-dependent suburbanite will tend to have a lower average.

Jogging / long-distance-running tends to be about twice that fast, or 2.3 hours of activity. Per day. Ten percent of their lives, running. Most people don't come anywhere close.

I am always surprised how little focus there is on the mental aspects of overeating. Losing weight is really simple - consume fewer calories, eat less processed stuff. And yet so many smart, otherwise capable people struggle with weight loss despite having an excellent knowledge of modern diet plans.

Food doesn't get in a person's stomach by accident, a decision is made with every meal, especially when a person is aware of being overweight. So why do people continuously keep making wrong decisions for many months and years?

My case was simple - I was depressed and food made me happy. Making a decision not to eat something was mentally painful. Fixing things that were wrong with my life eliminated both my depression and my issues with overeating.
The crucial aspect is the "crunch per bit" of HFT. We know that an electronic system is mostly an improvement over having pit traders yell at each other all day.

What we do not know and cannot prove without experimenting is whether our electronic markets benefit from following smarter, more complex rules of play instead of the same ones faster.

I frequently disagree with Nisbett's thought process and conclusions in his other writings, but this analysis of the problem with MRAs is spot on.

MRAs are in my view the last nest of resistant pseudoscience that is still anchored within the mainstream scientific establishment.

As a tool, they're not completely useless if you can't do a controlled experiment... but the misunderstandings of their proper usage case and the endless spurious headlines that result from MRA studies (Tofu being correlated with car accidents and the like) mean that I don't trust most people to utilize them properly.
No. A 'food calorie' ('1 Cal') = 1000 calories ('1000 cals').

The simple way to count it better is to round it up to 50.
So if you had a tea with sugar - thats 50. If you had coffee, instead of 70 - thats 100.
Then I also see a lot of people wont count snacks. Snacks and "bites" in between meals is a huge problem. Check how much calories have one slice of cheese or few M&Ms.

How I Lost 22 Pounds with This Weird Lemon Diet in Just Few Weeks
Works fine for me on OSX as well, but since this morning all our iOS devices have the browser crash when tapping the address bar.
I don't know, but I wouldn't jump to that conclusion; there are real reasons to be careful with fat.

Fat is 9 calories per gram, while carbs and proteins are 4. If you have a budget and you're counting calories, fat is more expensive per gram, so you might naturally develop an aversion to spending your budget on what appears to be less food (even if it's only appearance).

Too much fat is also unhealthy. How much is too much is still being debated, but there is a difference between a weight loss diet and a healthy diet. All things being equal, a 2000 calorie diet of buttered bacon doughnuts is still likely to cause more problems than a 2000 calorie diet of vegetables, fruits and nuts.
They confirmed that they're working on it but it's not clear that it was a purely a problem with Apple's code. Given all of the well-documented general stability problems t.co has had over the years it would not surprise me to learn that Chrome has a more aggressive recovery mode from a bad DNS server, failures returned by only one of the multiple servers which that hostname resolves to, etc.

I've seen plenty of t.co errors in Firefox as well as Safari, but never in Chrome and the network stack is one of the areas where they've clearly put a lot of effort.
That's just an example. I am building a custom CRM as part of a service right now. Or should I shoehorn Salesforce into this service and tell all my customers that to use that feature of our service, they have to also have a membership with salesforce?

My customers pay me for the features I am building all into this service... Not to charge them to hook a membership for another company up to it.

Then I have to provide support for Salesforce. Their service goes down, now I have my customers mad at me because part of my service is down.

No thanks.
"My advice: eat when you are hungry, eat real food, forget about macros."

This is always my go-to response when people ask me about my diet. If you simply eat only when hungry, and only eat real food, you're going to be in decent shape on average. There is a lot of detail and difficulty hiding behind those two simple requirements though.

For example, eating only when hungry implies that we stop eating when we are no longer hungry. Avoiding binge sessions is sometimes very challenging. And accepting a simple definition of "real food" can be surprisingly challenging. Things that don't make the cut: Frozen pizzas, almost all fast food, even orange juice.
Completely subjective, but I'm very drawn to the timeline. I would be interested in a site that was organized entirely around that, with the videos and pictures displayed chronologically and by importance.
These Four Awesome Puzzle Games Help Decode Coding

Yeah, so this is just another case of the principal-agent problem. The thing which is best for you as a programmer may not always be the thing which is best for the company paying you. You'll have to find a balance between the two, and so will your employers.

To a casual observer, 'millimeter wave' frequencies seem like a poor choice. From what little I know about RF, bands in the millimeter wave spectrum are going to suffer from lots of signal loss just due to attenuation from air and humidity, and won't have particularly great range or penetration capabilities.

That said, my knowledge of RF tech is limited to 'enterprise' wifi concerns and amateur HAM radio, so I might be missing something here.

No, they don't. In any panic, HFTs disappear like anyone else. They are middlemen, not producers. They insert themselves into the middle of trades to make profits for themselves.

If I put in a market order when the price is $100, and a HFT firm sees my order, beats me to market, buys up all the $100 offers and then resells the stock to me at $105, my liquidity hasn't been improved in the slightest. All that has happened is that someone has front-run my order and cost me $5/share, extracting profits from my pocket without providing any useful service to anyone.

Adolf Eichmann's Appeal for Clemency
Losing weight is like a Perlin noise function. The 'primary signal' is food intake. The 'secondary signal' is caloric expenditure (be it from the base metabolism or exercise). All the rest are tertiary signals. Yes, one can debate about the amplitude of each of the signals, but the message is: want to lose weight? Eat less.

The problem with articles like this is that it sends the signal: 'losing weight is hard, don't bother trying'. Or 'nobody knows how this works! What we've thought for decades is completely wrong!'. Which is a poisonous message. It doesn't matter that we don't know the exact details, or that we can't measure to the last 25 Cals. The higher-level principle (i.e.: yes, you body obeys the laws of thermodynamics) is still valid.

Slack's Reactji -- which lets you use any standard or custom emoji as a reaction -- is significantly more useful than Facebook's very limited set of options, and it came first.

At some point the crunch will become so severe that the resorts won't have enough staff. Then, they will realise that they might have to do something, and they'll house employees on-site.

Is there a story behind the development of the site?
If you write in C you are probably fine for code size. Usage of the c++ stdlib can easily cause a lot of code bloat though if you are not careful, but I don't actually know how bad this gets (it used to be quite bad for native apps).

There are other issues as well. The biggest offender being the inflexible heap size, e.g. when you launch an asm.js module, you pass in an array buffer as the heap which cannot be resized. If you need more memory than this, you are SOL.

This wouldn't be that bad, except in practice it needs to be ridiculously small if you want to run on most machines. 256MB, which not much memory for a game at all, will fail to allocate, or kill the tab on about 33% of machines (being generous. For us its probably more like 50% of machines, but we make educational games that need to run on university machines, which are uh, on the lower end).

Either way, as a result, a great deal of the optimization time I mentioned was spent getting all of our games to run with under 128MB heap.

That said it's definitely possible if you're careful (I'm not sure this is quite as true for a voxel game though, but I could be wrong). My complaint wasn't about the idea of using asm.js, it was the idea that Unity would produce a good result. It just doesn't.
There are two areas I would look at here

1. How much independence did the OP show creating the Amazon hookup? Was it his/her baby? Did they push forgot to happen? Or were they just rotated onto the project and it came with the next item off the backlog?

2. Was the OP the only one to add value that year? Was the value they added more than others or about the same.

Without these two it's hard to see if they should realise they are just an employee and have no leverage or if they did get shafted.

I think we all need to have more P&L responsibility in our jobs - software is about creative capital and should be highly leveraged.

Maybe we should all go back to the partnership model?
