OpenSSL was the epitome of horrible code. You can't make it any worse. Doing so would cause an underflow and you would have perfect code, which we know is impossible.
The correct thing to do is to have your border router lie about available TCP window size to the router on the other end, so that all intermediate routers between that router and the system transmitting the FTP packets in the first place also lie about how full the window is, and the intermediate routers don't end up with full input packet buffers with nowhere to send them in the first place.
What? The TCP window is meant to be negotiated only by the end points, not the routers. Core Internet routers don't care about TCP windows, that's layer 4, they just forward packets as fast as the can. If your downstream is getting overwhelmed, blame your your client OS or blame your ISP for over-subscribing too much, but don't blame the bandwidth differences.
If you have reliable download bandwidth, you shouldn't get latency issues. I have a baseline 12.5ms ping and it may "spike" to 30ms if I'm downloading at my full line rate from multiple sources. Slightly more than 30ms, and I get packet-loss, but my ISP properly manages buffers and doesn't cause my ping to skyrocket.
Someone recently asked this on the PFSense forums and the response was the Tomato's QoS is too simplified. They could create a wrapper to translate QoS style GUI into PFSense settings, but it wouldn't play well if some decided to make any manual changes. PFSense has a much more powerful QoS.
OpenZFS is going to gain async writes for mirroring. You can specify how many HDs to successfully write data before it returns completed. This way you have have 8 HD is mirror, but only have to wait for 2 to return and let the 6 other writes finish on their own time.
Doesn't creating a striped RAID make up most of the performance issues from using a HDD over a SSD? At that point, it's more the bus or CPU that's a limiting factor?
Don't forget about IOPs. A single modern SSD can do about 80k, while a single HD is about 2k. You would need about 40 HDs to match the IOPs.
You completely missed his point. Solving a problem is not good enough to be good at something, you need to understand the entire system to make something be good.
Here's another analogy of what he was going after. You may not need to be a physicist to be an efficient driver, but you best know some physics if you want to not be the idiot who put a wind-turbine on their car to get "free energy".
Anyone who only understands their own set of problems cannot properly solve anything, except by blind luck. You must also understand other people's problems. No one system is entirely isolated from all others. The more understanding of other systems, the better your understanding of your own system.
Or cost of living is crazy low, like around here. When the cost of living is low, the pay is also low, but that's Ok, because money has relative value. $600/month will get you a nice house around here, and you can get anywhere in town in under 10 minutes.
When someone doesn't know that they don't know something, it's like a "null" value. Their brain doesn't know how to handle it and assumes they do know it by thinking it's something they already know.
I've never once felt anything like that. I'm well aware of my limits and my ignorance, even though I strive to get rid of them both as much as possible.
Ahh yes, but that's because it's a perception issue. Most people do not realize when they do this, that's the issue. I can assume I don't do this often, but even then, I'm probably wrong. At least I am aware of the issue and don't write it off as "I never have this issue". People who think they are immune are the ones most likely to be affected.
You learn a lot about learning.
You learn a lot about learning by learning, or using your brain. As for interaction, that can be achieved in other ways that don't involve spending tens of thousands of dollars.
There are other ways. I find/. and other sites great, but they're still not as good as the experience I had in school.
As well as it may have worked for you, for most, it won't end as well. I also agree that even college is slow paced for learning, but not everyone can learn really fast in all subjects. My upper level classes had quite a quicker pace than the lower level, but most of the "baddies" were weeded out by Jr year.
I would argue that I learned more in my Generals than my Major. They strengthened my critical thinking quite a bit. I'm used to doing critical thinking and research on computers, but I'm good at computers and have a lot of knowledge. Doing critical thinking and research on subjects that I have less knowledge and experience is COMPLETELY different. The most important thing you'll learn is "what you don't know".
When someone doesn't know that they don't know something, it's like a "null" value. Their brain doesn't know how to handle it and assumes they do know it by thinking it's something they already know. False positives.
Couple that with having whole-class discussions about different points of view, pros and cons of those views, and the reasoning being those views. You learn a lot about learning.
4 year Uni greatly increased my critical thinking to the point that the knowledge acquired was almost worthless. But if you talk to any of my teachers, that's what their goal is. So many after-class chit-chats with a wide range of teachers. All very nice people.
Anyone can acquire knowledge, anyone can acquire experience, but the most important thing you get some a good University is neither of those and is more important.
Only if you have some really crappy schools. The primary thing taught in college for me was critical thinking. Nearly half of every class on every topic was a discussion about how, why, and implications. Most classes, including GDRs were tested for understanding and reasoning. Most tests were setup in a way that the written portion was weighted heavily. If you had a good grasp of knowledge or understanding, but not both, the best you're going to get is a "B", to get an "A", you really need both.
Every GDR that I took had a lot of written portions to test and project work, except Wellness class. That was a cross between "class" and phy-ed.
When I think of a "tech job", I don't typically imagine a first line tech support that reads from a script or someone that installs network lines after having in-house training and just doing repeated step-by-step instructions.
Of course you don't need a bachelors for a job that has little critical thinking requirements. If you want a secure job that pays well, is salary, and has good benefits, you may want a bachelors degree.
Except I can CHOOSE to not own a car, and I don't need insurance at that point.
Call me when I can CHOOSE to not carry health insurance.
That's why so many are crying foul.
My question is why we didn't just roll this whole broken process under medicare.
It's not like the government hasn't been in the health industry for the last century anyway.
At least then it's less confusing who's robbing you. Better the devil you know.
You can choose to not drive, which means you can forgo car insurance. Same thing with health insurance. You can choose to not be alive, which means you can forgo health insurance. But like driving, a person being alive means that on average, they will go to the doctors and cost society money. We're just asking that they pay their fair share before they drink it away at the bar.
I had a situation like this once. Then I talked to someone in my HR at work and they called the hospital and got my insurance on the phone and found out the price for me. The HR lady told me if I get a bill that is more expensive than that, she'll get it straitened out. I love the HR at my work.
Some people go in to the ER for their yearly checkup. Can't afford the $200 doctor's visit, so they hit up the $2,000 emergency service and get the whole work-over. Then the hospital says, "you're good", and sends them home with a bill that gets forgotten about. It's cheaper to have them go into the $200 doctor's visit than to pony up for the ER.
How? Where I work, you get auto-enrolled. Every year, you must explicitly decline to get insurance and sign a waiver. Dental and Vision are not this way, the health insurance is.
Even if they pass a law stating it, no major medical educational center will support it. There are a lot of ethics involved with being a doctor and abandoning those ethics, even if support by law, will land you with no license to practice.
$60 for a doctor's visit?! Don't make me laugh. More like $200 for the visit and another $500 for all the tests like blood work. My wife recently went to the ER because she had a sharp burning pain in her pelvis and it was in the middle of the night when it started, so no other offices are open. All she did was sit in a room for 2 hours, a doctor stopped in, talked to her for 5 minutes, and told her it's a pinched nerve, sent us home with a $900 bill.
Don't tell people to pay for their own healthcare until we've made healthcare affordable.
You preach about managing your own money for healthcare, but most of the cost of healthcare has nothing to do with you. The largest cost to healthcare is the hospital taking losses on people who can't or won't pay, so the hospital charges everyone else exorbitant prices to cover their other losses. Around here, hospitals are not allow to turn away anyone that comes to the ER for any reason other than capacity. Even if they know the personal cannot or will not pay their bill or they fake issues, the hospital is required by law to see the person and only release the person once the hospital as proven that they are safe to send home.
I don't remember the exact numbers, but I remember going to my University, the poli-sci went over the numbers and the amount of money we spent on the "war" over 3 years was enough to cover all hospital costs for all of the USA and send everyone to college, assuming the average cost, for 10 years. I would personally rather have a highly educated healthy society than running about the planet killing other people who pose less threat than pollution or drunk drivers.
Many times, the crazy hours do not increase your pay. If anything, having "crazy hours" reduces the number of people the employer will hire because they figure they can jsut get 40 hours out of you at work and another 60 hours at home.
And this, ladies and gents, is why unmanaged languages need to die.
I know the feeling. Every time I read about a SQL injection attack, I think, many, they need to get rid of relational databases and every time I read about someone's computer getting hacked, I think, man, they should get rid of the Internet.

They've removed over 50,000 lines of code as of several days ago. I'm sure there are fewer bugs.
Will probably have to change to another name though.

They can't discharge you until you are stable and capable of taking care of yourself. Both of which, they must prove.
Some people go in to the ER for their yearly checkup. Can't afford the $200 doctor's visit, so they hit up the $2,000 emergency service and get the whole work-over.

Not "easy" to fix, but "simple" to fix. Digging a lake with a spoon is simple, but I wouldn't say easy.
