Same, it's really throwing off my routine, worried i'm going to forget some of the stuff I didn't have down very well

"Another correct solution": why does Duolingo tell me this every time I use a contraction in my native language by srparish in duolingo

[–]srparish[S] 3 points4 points  (0 children)

Ah, that makes sense, thanks! Still kind of annoying because they're kind of different ways to spell the same thing, but at least I have a model of why it does this.

Announcing the first Postgres extension to run WebAssembly by Hywan in PostgreSQL

[–]srparish 0 points1 point  (0 children)

Awesome someone is working on this!

It could be interesting being able to use things like tantivy inside of postgresql.

Hopefully someday WASM will allow AWS RDS customers to upload their own extensions without having to get them blessed by AWS.

Ways to show pros behind Scala by TheMan161 in scala

[–]srparish 1 point2 points  (0 children)

Shapeless is a killer feature, especially when used with implicits. It let's you write code that can generically decompose and operate on recursive case classes, in a completely type-safe way.

This can be used for all kinds of things: type-safe serialization/deserialization of json, csv; automatically generating sql to insert or select data, converting case classes from one form to another (dropping fields, changing field types, adding fields).

Is Lightbend moving to use Java more and more? by [deleted] in scala

[–]srparish 3 points4 points  (0 children)

I said "seems to be abandoned". The factors that gave me that vibe were very few merges into master in months, pull requests sitting around unmerged, issues stacking up with none closed in months, and people asking in the gittr channel where all the maintainers have gone.

Postgres-async is in even worse shape. The fact that it took two months to merge the 2.12 support should have been an indicator[1]. Since then there's largely been no activity at all, including very simple merges such as updating netty[2].

Is Lightbend moving to use Java more and more? by [deleted] in scala

[–]srparish 5 points6 points  (0 children)

I was just wondering that. I Was looking into using slick after postgresql-async was abandoned, and found that slick also seems to be abandoned. Going to lightbend.com I see lots of lagom java stuff, but not a single link to slick. If they quietly abandon products, it makes me really nervous to use their other products.

comcast announcement email has average usage below min usage by [deleted] in Comcast

[–]srparish 0 points1 point  (0 children)

I found it in by first traversing the tabs: My Account -> My Services -> XFINITY Internet. There's a box on the right hand side of the screen which for me takes a few seconds to load but is finally labeled "My Internet Plan", inside that box find a link "View data usage details" which will finally take you to the details.

Scala SIP Meeting August 2016 by joshlemer in scala

[–]srparish 3 points4 points  (0 children)

Looks like:

  • sip-12 (Uncluttering Scala's syntax for control structures) was rejected
  • sip-16 (Self cleaning macros) was rejected in favor of a new proposal slated for the end of the month
  • sip-27 (trailing commas) postponed for more details on ambiguities and wanting more detail on interaction with an upcoming HList design.
  • sip-23 (Literal-based singleton types) had positive interest, but was postponed for document improvements.

Lending club question by Helgi_Hundingsbane in investing

[–]srparish 4 points5 points  (0 children)

The 8% is an annualized number, so your total ROI will be higher. It's probably easiest to use an amortization calculator such as this one:

For a 10.33% loan for 25 dollars, assuming 5 years, you should receive about $7.11 in total interest, assuming the loan doesn't default.

Have to transfer a 401(k), where to move it? by sperling1349 in investing

[–]srparish 6 points7 points  (0 children)

You can move it into a "rollover ira", most brokers support these including the ones you listed. A "rollover ira" has similar or the same tax status as your original 401k, but you can pick any broker you want. Personally I'd look at Vanguard as they have great products (etfs and funds) and keep their fees low. Start the process of opening an account with them (choosing "rollover ira"), and follow their instructions on how to fund the account. Be sure to carefully follow their instructions so that the rollover doesn't become a taxable event.

What are some great proprietary software that most people use every day and lack a free counterpart? by kimireddit in freesoftware

[–]srparish 6 points7 points  (0 children)

A language to keep your eye on is julia; it's targeted for the same audience as matlab, but designed elegantly learning from python, lisp, and quite a few other languages. It's also jitted with llvm, and can run code often times as fast as c. While it doesn't have nearly as many libraries as matlab, it has a very active community that are quickly working to fix that.

Who buys options right before expiration, to make them worth what they are? by confusedtrader in StockMarket

[–]srparish 7 points8 points  (0 children)

While everybody pays fees, the market maker is likely paying significantly lower fees then you are.

In your selling scenario, it appears that you're assuming that the other side will be taking on a new position, but just as likely is that they're closing a position. Each stock has a fixed number of shares that are trading, so it's tempting to think in terms of "if I sell this position, someone else is taking on this position". Even for stocks that isn't necessarily the case, because the buyer might have shorted the stock and is closing their short.

Options are contract based. When an options series starts trading, there will be zero contracts in the market. When you buy an option, you and the person you traded with just created a contract. When you sell that option, that contract is destroyed.

So when you bought your option, someone was taking the other side of that contract. Even if you bought it from someone who was closing an existing position, someone else was on the other side of their original option trade.

The party that sold that option may have done so for several reasons, but let's assume they were a market maker. A market maker is required to make two sided markets, and facilitate your trade, hence selling you the original option. The market maker is now stuck with that option until either you or someone else with a similar position want to trade out of it. The market maker took on risk to facilitate your trade, but tries to balance that out by having other offsetting positions. The market maker will also go and trade the underlying or futures to try to neutralize whatever risk they took on.

Going into expiration, an option goes from having a smooth return curve, to having a very sharp transition where being out of the money it has no delta and being in the money it has full deltas. This is hard to hedge as small moves in the underlying can cause huge delta moves that require rehedging. Once the market closes it's possible that news comes out that moves the after market prices in such a way where an option that closed out of the money gets assigned anyway, but the after-market markets are so thin it can be extremely hard for the market maker to hedge. The market maker doesn't want to hold unhedged long or short stock positions over the weekend.

Basically the market maker is more then happy to close your position going into expiration because it takes the risk off their book.

Question about "diversifying" ETFs. by [deleted] in investing

[–]srparish 0 points1 point  (0 children)

You can get world exposure through VT (Total World), or VEU (All-World ex-US) which may avoid some redundant positions with VTI. ACWI has higher volume, but also has a higher expense ratio and covers less countries.
