So why is it important to have a multisocket NUMA machine? Why not just save yourself a lot of hassle by having one socket? I know that the previous generation AMD machine had unavoidable NUMA but the new one doesn't.

It's money. Having a two-socket machine instead 2 one-socket machines, even when performance is only 80%, is saving both OPex and CAPex.

I agree with the 1st pattern.

The 2nd one, there's a caveat about space/GC here.

The 3rd one depends a lot on the situation.

4th one is too obvious for it to be called a pattern, but I agree with it.

5th one is, meh, not really easy to read. I prefer his "bad" example. It could be less verbose, e.g,

if (!conditionA) result = "Not A"

else if (conditionB) result = "A & B"

else result = A

I don't get the "as birthrate sinks and unemployment climbs". It's not like Japan is doing well there.

And Japan is infamous for its incredibly negative attitude towards Koreans...

Have to admit I am clueless about the history between these two. Why don't they like each other?

Does anybody have experience in getting DDOS'd? All i see are 3 ip addresses (offending) in the screenshot and it makes me wonder how many is typical?

I have never been ddos's and all I ever receive are failed ssh attempts with simple passwords. Pretty much the easiest thing to tackle. But I'd love to know from DDOS'd people how their attacks looked?

From cloudflare logs all I see is a single IP address being blocked (multiple times? Or is it their multiple actions being blocked?).

EDIT: Thanks all, these were helpful answers.!

By definition, DDoS is Distributed. From my experience working on a Layer4 DDoS Protection solution, a typical case often range from 1000 to 100k flows.

Western tourist also immediately notice it when they come to SE Asia. It's a pity that this is such a strong memory.

As a Vietnamese local, why do you think the plastic pollution is so widespread here? Sure, everything is packed in plastics, but so is in Japan. Why do people just not think twice about throwing their waste in a ditch or a river or leave their picnic at the beach? Or is most of it coming from the sea? What could change the mentality?

> Why do people just not think twice about throwing their waste in a ditch or a river or leave their picnic at the beach?

I think there are two main reasons. First, many people don't have environmental awareness. They weren't taught. That's not to blame them, but it's just a fact. However the new generations are indeed educated on that subject. We were taught to not litter, to pick up the trash, etc. But this is where the second issue lies: when we don't follow the rules, nothing happens. No immediate consequences. Whereas in other developed countries, when people break the rules, they get fined, they get other people looking at them funny. That collective awareness helps enforce the simple rules.

How big is social media there? The #trashtag trend is really awesome, and would be good to get going. It's using people's desire for attention to do some clean up.
baolongtrann · 7 years ago
Social media, mainly facebook, is absolutely huge over here. I have seen a few popular local #trashtag pictures circling around. We generally catch up with internet trends pretty quickly. I wouldn't be surprised if it made national TV. It's awesome but unfortunately I don't think it would help much in the long run.

Vietnam is a stunningly beautiful country but unfortunately a love of nature doesn't seem to have really taken hold there. At least not yet. Missing from all the gorgeous photos of Mekong Delta waterways and pristine beaches is all the trash you'll find strewn in heaps everywhere.

My guess is it will take another generation for people there to appreciate how blessed they are to live in such surroundings but by then it will unfortunately be too late. To some extent this is just the inevitable consequence of a small but populous country hurtling into modernity but there are also some important cultural attitudes that need to change.

I'm a Viet, born and raised. My country is blessed with incredible scenery, diverse and natural. The coast line is as long as the country itself ffs. Now I won't claim that I'm an avid traveler, but from my limited traveling experience (only been to Australia, Korea, Japan and Hongkong on vacation, nothing too fancy), I have never been to a place that I would rank higher in terms of beautiful, natural scenery.

However, the one thing that always caught me off guard from the few oversea trips that I've taken is that _everything is so clean over there_. That's literally the first thing that I always noticed when I get there and when I came back. Makes me feel sad, envious, and shameful.

> This may be why the field emerged from dentists rather than orthodontists.

Orthodontists are dentists.

baolongtrann · 7 years ago
but dentists aren't always orthodontists. I think OP meant those that aren't.

Can anyone comment on this new bundle. How is it compared to the Wiley one?
