Stealth is somewhat overrated, especially 5th gen. Sure you get a lower radar cross-section which means you are less visible to X-band radar but near-peer adversaries or even non-peer technologically advanced adversaries don't rely onl

I don't know the situation at MIT in particular but overall creating some budgetary pressures for universities is probably a good thing. Every since it became near impossible to discharge student debt due to legislation in the Bush pre

The idea that simply having a lot of parameters leads to overfitting was shown to not be the case over 30 years ago by Vapnik et al. He proved that a large number of parameters is fine so long as you regularize enough. This is why Support V

Nope. Abuse should never be accepted. The right solution for actual abuse of a policy like this as opposed to an error is to immediately fire the person conducting the abuse. The inability or unwillingness to make decisions like this fast i

Has anyone tried Mikrotik routers? The one I tried a while ago was fantastic.

If you enjoy writing and love writing with a Vanishing Point, this is a question that is very, very dangerous for your pocketbook. :-)

Kakunos are awesome. Really good nibs. Awesome value for money.

You do need to cap fountain pens because the inks are water based. If you need to take quick notes and drying out is a problem because the pens are uncapped and capped a lot, get a Lamy 2000, vintage (not new) Parker 51 or a Pilot Vanishing

It's extremely rare to get a nib that isn't tuned pretty much perfectly if you buy a brand new pen made by one of the Japanese big 3, Pilot, Platinum and Sailor from an actual fountain pen retailer (online or brick and mortar). I&

The Pilot Metropolitans sold in Europe use standard international cartridges. The ones used in the US use proprietary Pilot cartridges.

I haven't had this experience with TWSBI. They used to have somewhat more finicky nibs before they switched to using Jowo nibs. I've found the nibs on TWSBI pens to generally be pretty well adjusted Jowo nibs. They aren't the

While I love many Noodler's inks and have many bottles from him too, while this used to be the case, this hasn't been my experience recently. In my experience the inconsistency has if anything gotten worse recently. Worse, the bot

I haven't had any trouble with TWSBI's bought in the last 2-3 years. Besides they have a crazy good lifetime warranty. I've had a pen stepped on, emailed them and told them so and they shipped a replacement barrel to me for s

Love my Pelikans. But the M800 and M1000 retail for more than double the most expensive pen on my list. They are awesome but not necessarily a better writing experience than the pens on the list. Still, they mostly didn't make the list

Totally agree. Properly restored vintage pens are absolutely awesome. You don't have to go as high end as a vintage Parker 51. Try an Esterbrook. They were the BIC of their day and are amazing. Very important warning regarding Parker 5

Traditionally, you are supposed to write with less pressure and even hold the pen with less pressure. Once you teach yourself to do this, it is much less tiring than writing with a ball point pen. I write a lot. It's how I think. I&#x2

This list is certainly not classic fountain pens. They are mostly machined pens made by small batch producers with generic nibs and two with somewhat "different" nibs I wouldn't normally suggest most people get. These are pre

They would have gotten their principal back but missing out on interest for 10 years is a huge cost, particularly if you have to pay out interest in the interim to your depositors.

The divergence in AIG occurred to a large extent in 2010. However, this effect is present for most stocks and the indices as well and has existed for pretty much as long as we have reliable data without survivorship and lookahead bias. Is i

In the US the stock market officially opens at 9:30 and closes at 16:00 NY time every day. The day return is the return from the first trade (the official opening price but it would take too long to explain the the difference) at or after 9

A large trading firm, particularly one that had the capability to trade cheaply enough to take advantage of this effect would never do this simply because 50%+ of the return of a single stock is determined by the return of a common market f

It's very easy to talk about completely automated systems and LOTO and you need these when you have under-skilled staff. The NYSE likely does NOT have under trained staff. If you have LOTO systems etc, what do you do when a sensor fail

It's not a gain even purely from the lens of consumer choice unless there is only one iteration of chip improvements ever. Why? Because if this is permitted, there will be no company A to do the research to create the next generation o

C++ is a systems programming language. Just like C, it allows you to do anything you want to do and be as close to the hardware as you want to be. This is completely unnecessary if you want to build something that displays pretty pictures o
