I work on the ledgering system at clear street and as far as I know we have no plans to do this. We evaluated it internally a few years ago and found that the account and transaction model was too different from ours to migrate over.

>I have worked with Indian subcontractors that have waited 20 years!

And you think this suspension will help them?

ITT: People criticizing the H1B program for reasons that have nothing to do with why it was suspended, or considering the fate of people/families who are already here on H1Bs.

This is a pretty obvious move by the administration to discourage immigration, in any form. Could the H1B system be more equitable to workers, more efficient, less confusing, etc? Absolutely. But suspending H1Bs and green card applications like this does the opposite of all of that and throws thousands of families into limbo.

>Getting caught up in the parts of a job that don’t matter is a dangerous trap and for some reason one that a lot of people fall into. Let other people play political games and avoid them as much as you can.

My experience at big companies is the inverse. The people who advance are the ones who spend 80% of their time focused on politics, while the heads down engineer will get a thank you and inflationary raise.

You're not wrong, this headline is very poorly worded.

From the article:

>A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers, eight of them in Asia.

>The 10 rivers that carry 93 percent of that trash are the Yangtze, Yellow, Hai, Pearl, Amur, Mekong, Indus and Ganges Delta in Asia, and the Niger and Nile in Africa.

So to say "10 Rivers Contribute Most of the Plastic in the Oceans" is not really correct, they contribute something like 25%.

Law suits seem to be the standard tactic for dealing with other types of corporate negligence (for better or worse). Why aren't they employed more for these types of obvious security vulnerabilities if you can demonstrate harm?

> The cause? A coder had mistakenly programmed a router to send placeholder bids as live orders. If not for the good graces of the options exchanges, the bank would have lost $500 million, according to the U.S. Securities and Exchange Commission. Cancellations and price adjustments reduced that to $38 million

It's interesting to read the full SEC report because it's a little more complicated than that: https://www.sec.gov/litigation/admin/2015/34-75331.pdf

It basically outlines a cascade of failure in controls, bad configuration defaults, and poor SDLC. In particular:

>In addition, the firm’s operation and management of its electronic “circuit breakers” did not effectively block the erroneous orders sent on August 20. These circuit breakers existed to prevent erroneous orders by halting all message traffic to the exchanges once that traffic had exceeded a certain rate. However, on August 20, the firm’s control personnel repeatedly lifted the circuit breakers blocks between 8:44 a.m. and 9:32 a.m., thereby permitting additional erroneous orders to be sent to the exchanges. Before lifting the circuit breaker blocks, the control personnel did not obtain authorization from the responsible technology employees, as required under written firm policies.

>The firm’s policies relating to the manual “lifting” of those circuit breakers were not disseminated to or fully understood by the employees responsible for deciding when the circuit breakers should be lifted, and, prior to August 20, 2013, GSCO personnel had lifted circuit breaker blocks shortly after learning of the block and while still investigating the cause of the circuit breaker trip.

From what I remember, this circuit breaker was notorious for raising so many false positives that control personnel just got used to lifting it without thinking.

Why can't you publish multiple salary ranges per job post (level 1: $X1 - $Y1, level 2: $X2 - $Y2, etc) or multiple job posts (one for each level)?

Neglecting to publish a salary range seems more like a negotiation tactic on behalf of companies of not wanting to be the first to name a number. Either that or you know your company can't compete on salary, which is my typical assumption when it's a company I've never heard of and I don't see a range provided.

As someone who works in a bank, if I sent trading data off to an external service I'd be fired almost immediately. Even things like pretty printing services are monitored and blocked.

>I distinctly remember that most of the mean scores were between 8 and 9. One was as high as 8.7.

I was told by several people that the ratings are normalized to adjust for this.

Markov chains have a lot of nice features you can derive from them, like convergence to a stationary distribution. It's hard to say that it's an inappropriate simplification if it happens to be pragmatic (like most simplifications).

For example PageRank can be modeled using markov chains. You can surely develop more complicated models but markov chains provide a good starting point.

>neither Wal-Mart nor Jack’s nor the nursing home cafeteria have shown interest in an applicant with psoriasis and a ninth-grade education.

People who only have ninth-grade educations aren't the greatest at basic math or delayed gratification.

REST doesn't have to be JSON, it's agnostic with regard to the serialization format. JSON is just a popular format but I've seen XML and YAML REST apis.

I have the Costco Amex too, but how often are you going to Costco that you're carrying it around everyday?
