module0000··on Business networking is overrated (2017)
You made me look up 'guanxi'.

(from ddg) guanxi: Guanxi describes the rudimentary dynamic in personalized social networks of influence and is a central idea in Chinese society.

I hoped that wouldn't be the answer :(

That's funny - I thought it sounded really nice. It evoked nostalgia from the military. Different strokes eh? :)

That's disturbing! Why is that?
module0000··on Glowing reviews tout counterfeit cash on the dark web
In the US(Army) we all have to do a gas exercise. We go into a chamber with our gas masks on and watch the agent being activated and released. Then we remove our masks, recite our name, rank, and serial number, then put them back on. It doesn't last long, but no one in my platoon "barely noticed". It was pretty debilitating - vomiting, coughing, snot smeared all over your face...etc.

That said, there are a lot of different gas varieties, and I've only been exposed to that one.

module0000··on One of the Biggest At-Home DNA Testing Companies Is Working with the FBI
If this bothers you, consider fighting back. Submit as many DNA samples to as many firms as you can find. Send each sample from a different [consenting] donor, and ask that they do the same and include you among their donors. This action at scale dirties the data sets of all the companies involved.

>> I mean, fundamentally, how is it different from the police asking a hotel administrator whether John Doe stayed there?

I don't think it's different. Hopefully the hotel operator has the good sense to tell any law enforcement without a warrant precisely where they can shove it. It sounds like this DNA company does not have that good sense, however.

Darn you, now I had to go through the same process. The page to delete the data was not obvious to locate - scary and sad.
module0000··on Apple blocks Google from running its internal iOS apps
Not using any installation mechanism provided by Apple. If you want to crack open the phone and begin trying to pin out the storage controller: then maybe.

The installer is a piece of software made by Apple, to install things that meet certain criteria(ie signed packages). It's not that you can't technically "install" other things, but there doesn't exist a mechanism to do so.

module0000··on Apple blocks Google from running its internal iOS apps
>> Apple should not have the right to enforce those conditions to begin with

Apple is not a state-owned company. They can do whatever they like, and you can choose to support them by purchasing their stock and/or their products. You can choose not to support them by purchasing neither their stock or their products.

There are several federal and state laws that define what they "can not do", and this isn't one of them. Why should a business owner(s) "not have the right" to run their business any way they see fit, so long as they do not violate the law?

Your analogy to MS doesn't hold water - MS was told not to do something by a governing authority, and they did it anyway. The governing authority stepped in and enforced their rules - nothing out of the ordinary there.

module0000··on Google Takes Its First Steps Toward Killing the URL
You're right, my phone number comment really didn't add up after I read your response. I can't think of a good solution for your example, even something as well known as Steam or American Eagle falls apart when the average person is presented with multiple choices. Short of spending loads of $$$ buying every domain similar to your company name, I don't see any good solutions. Sad state of affairs :(
module0000··on Google Takes Its First Steps Toward Killing the URL
I'm not trying to be BOFH here... but it's not unreasonable to expect web users to have the same basic knowledge of a URL that they have for a telephone number. Most(perhaps nearly all?) of telephone users in the US know that in 123-456-7890, the "123" is an area code, "456" is an exchange, and "7890" is the line number. URLs are not that different. A similar knowledge of URLs would serve users well.
module0000··on Can a Machine Learning Model Predict the SP500 by Looking at Candlesticks?
No, not at all. Move along. Everyone tries this initially, and (quickly) learns this lesson. I suppose it cost you a lot less to find out the answer via posting to HN though.

Really gets to the heart of how the ruling 0.0001% of the US treats the rest of the world. Fixed that for you. Some of us just live here.

module0000··on Instacart paying 80 cents an hour because worker received a large tip
Vote with your wallet - tweeting/posting/complaining is fine and should be done - but denying them revenue is a universally effective message to bad businesses.
module0000··on Your live coding demo is boring me (2015)
No I'm an ordinary professional. I don't start typing until I've thought it out, and then it's a very mediocre 100-115wpm. I'm saying the article author must be an exceptionally slow typist, or prone to mistakes - not that I am anything more than average.
module0000··on Your live coding demo is boring me (2015)
From TFA

>> I can think faster than you can type

No, you can't. Just because the author operates at XYZ skill level, does not mean the rest of us are similarly impaired. I'm sorry he had to sit through so many boring coding presentations that he purposefully chose to attend.

module0000··on At least 14,000 unpaid IRS workers did not show up for work
Adding to that... if they were "ordered" back to work, can they face any penalty by quitting? If so, it seems like a liability to be a federal employee in these times.

edit: typo

module0000··on US shutdown: Flight delays caused by staff shortages
>> They can't pay for informants.

This probably isn't the place, but I don't want them paying for informants. There is no vote I can cast to stop this practice. Effectively, I have no choice but to have the money I work hard for taxed and used in this fashion.

I too have labored in the hell that is 4gl Progress development. I did it long enough that I wrote a Progress-to-MariaDB replication daemon. That made it possible to actually get insightful reporting out of the mess that was the ERP system's database.

module0000··on The US spends more on healthcare for no gain says new report from Johns Hopkins
You cap healthcare prices for insurers because they are heavily influencing the provider prices.

Both institutions work in tandem[0] with one another to establish pricing guidelines. That's why your hospital-purchased ibuprofen is $10 per pill instead of $6 per bottle. The insurer and hospital "work out" a price that let's them achieve the profit needed to pay their administrative costs, plus margin.

In the USA(this is all from a US citizen's perspective), there are regulations that limit what percentage(15% in my state) of an insurer's income can be profit vs administrative cost. This means that a higher hospital price results in a higher profit for the insurance provider. This provides both parties an opportunity to set prices for an optimal profit. With government-mandated health insurance participation, the pool of people paying into this system has increased.

It is what is. Tell your elected official if you think it would help.

0: Anthem, Blue Cross, and UHC executives sit on the Baptist Health(hospital chain) board of directors, and vice versa.

module0000··on Apple Had Five Ways to Fuel Earnings. Only One Still Works
There are minimum hold times, otherwise 2 things happen: short term capital gains(high taxes), and the SEC flags you as PDC(high liquid capital requirements, compared to non-PDC).
module0000··on How Two Tiny Volatility Products Helped Fuel a Sudden Stock Slump
For execution I use Tradovate(which uses Dorman Clearing LLC). They have low commissions, and offer a membership to reduce commissions to $0(you still have to pay exchange costs though). Before Tradovate, I had used AMP for execution, but eventually left them over the cost of commissions.

I use a 8 tick stop and a variable profit target(a result of weekly re-optimizing). Last week the target was 24, and the week before the target was 16. The stop loss value I don't like to change, and 8 ticks has been enough for "good" entries. If I need more than 8 ticks, then I believe the entry price is my mistake - not the stop loss value.

I perform optimization every Friday, using that week as the training data to find the "best" thresholds for changes in depth before signaling a trade. Then the next Monday, I'll use those new values all week(and repeat the cycle that Friday). Basically - re-optimize every week. It's not a lot of work, just input the starting date, click optimize, and wait ~20m for the outputs. I like to keep track of each week's settings, with the plan to one day review their changes, and try to reason about why those changes happened(I haven't done this yet though, it's one of those one-day-I-ought-to ideas).

I don't have any algorithm parameters for unexpected volatility, the closest I have is a condition that turns the automatic entries off if the nearest 4 bids and asks(examining a total of 8 prices) contain more than 4 ticks of spread(no bids or asks), and both sides limit orders sum to less than 30. I didn't add that until sometime around Valentine's day 2018(that was not a good couple-of-days). When that happens, it disables entries and sends me an SMS.

module0000··on How Two Tiny Volatility Products Helped Fuel a Sudden Stock Slump
Oh certainly yes it is, but that's just not my use-case(anymore). In the past(when I had longer-lasting positions), the VIX was a useful indicator of "is this move real, or not?". Typically, if all 3 of the major equities(NQ,ES,YM) move in tandem over a 5-30s period, and the VIX inversely matches their movement - then that was my entry signal. When the VIX doesn't match, prices tended to return to their starting point moments later. If you speculate as to "why did the prices snap back?", my best guess was it was the result of profit taking or bad positions puking.

My current use of the VIX is more short-term. Over time, I found ultra-short-term positions worked out the best for me(in terms of profitability, stress, and opportunities per day - stress was #1).

module0000··on More games should be honest about death
Go play you some old school Counter Strike - with a handgun containing 7 bullets, you can frag 7 players. Also, 1 other player with 1 bullet can frag you just as easily(or not, headshots are tricky).
module0000··on How Two Tiny Volatility Products Helped Fuel a Sudden Stock Slump
It's supposed to be, but I stare at it every day for 2 hours(for years)...and it just doesn't work out that way. Half the time moves initiate in the VIX, and only moments later does price move in equities.

Example: this morning at the open, the VIX rose 7 ticks in the first 20 seconds - there was almost no volume to the opening move(on the VIX), and price(NQ) was kicked down 20 points. When the NQ was at this bottom, the inside ask for the VIX changed from 150-ish to 700 - the NQ price moved back up 20 points, but the VIX did not move. The only thing that changed was the depth. Now the NQ is right back at the open...that same 700 ask faded back to 100-200, and the price dropped back another 20 points. Keep in mind, this is the first 5 minutes of the open. It doesn't get more chaotic or random than that period of time. However, as chaotic and random as it might seem, it's like this "most" days(say, 7 out of 10).

One of the large reasons that instruments(like the ES, NQ, or VIX) don't behave the way the way their prospectus might indicate...is humans. Another example, the NQ is supposed to reflect the Nasdaq 100 basket of stocks, weighted appropriately...yet it does not. There is a whole school of trading around "program trading", which is automated trading to fade price movements when this imbalance occurs. If the prospectus is to be believed, this imbalance should never occur. Human beings are the answer: a fund manager has a gut feeling(or some technical analysis, or signal) that equities will move up, so he shorts the VIX for 2,500 contracts, which will absolutely move equities up, at least temporarily. It's not the rules or defined behavior of either instrument - it is the intent of someone with enough margin to execute a 2,500 contract trade. That person(and persons like him/her) are the ones controlling those instruments - not an arbitrary set of rules, or the formula laid out in the instrument's prospectus.

After saying all that...also realize a lot of this is truly random. The moment in time that Trader Joe and Trader Bob both kick off 2,500(or 10,000 for that matter) contract trades is not known by anyone but those humans. So to them, it's not random, but to hundreds of thousands of other market participants, it's random as hell, and causes a lot of "whoah man! did you see that!?" moments. Those pesky humans get in the way of everything :)
