Compressed data leaks information. There have been many side-channel attacks using the resulting size of the data and figuring out what information is in there. Pretty much, statistical analysis.
Just wait until IPv6 with IPSEC becoming standard. All you will see is a Layer 3 packet with no indication of protocol or port number. All layer 4 data is encrypted.
What? Server side certs are so the client can trust the server. Once the connection is secured and the client trusts the server, then the client authenticates with a user/pass. The user/pass is in place of the cert. Client certs is a pain, you need to not only store all of them, but you need to validate they're signed by a CA, also meaning each user needs to purchase a cert from a recognized CA. Have fun logging into your email or whatever web service from a computer other than your own. You'd have to install your cert.
A cert is just a way to authenticate and has no bearing on the encryption.
Self signed certs are worthless outside of knowing it's the same cert, which is still useful in an anonymous system. But if you're using the cert of anything resembling "this is me", self signed has no value.
New expensive hallow fiber is about 99.5%c, while regular fiber is about 65%c. I'll be happy with regular fiber for now, but once I get 1gb Internet on the cheap, the next upgrade will be hallow fiber trunks for low latency gaming. Regular fiber for the last mile will be fine.
They do, I've seen videos released from some pretty prestigious research Universities. They may be squirming poop makers, but they do make reliable reactions, once you figure out what those reactions are. When something caught their attention, they showed signs of interest, like reaching or staring or gripping, among other things. They may not have much conscious control, but they do have innate reactions.
Using these indicators, girls tended to find interesting in "girly" things and boy with "boyish" things, with a fairly strong spread. The spread was even stronger if you ignored the sex and focused on fetal testosterone levels.
At the early age of less than 1 hour old, boys show a preference towards mechanical toys and girls show a preference towards toys with a face. It's also interesting to note that these are similar indicators for autism, and boys have 5x the autism rate.
Strong evidence is showing girls like "girly" things and boy like "boy" things starting from the age of "new-born". More research is needed and more critique is needed, but it's looking pretty strong. Even more interesting is that it is less correlated with the sex of the child and more correlated with the testosterone levels in the mother during pregnancy. On average, guess which fetuses are exposed to more testosterone on average?.... Boys.
A woman who is interested in the same thing as a man, will more than likely me just as good as them. The problem is women and men tend to be interested in different things. So, of course, women in chess leagues tend to be about as good as the men, but if you look at the extremes, men tend to have more extremes. A very obsessed person will more than likely be better than someone who is not.
If you compare the median of men or women, you probably get similar results, but if you look at the 99.9th percentile, men will typically be better. But they also tend to have some personality issues at those extremes.
Speaking of reflexes, how does alcohol affect reflexes? I've had some interesting reflexes while drunk in my time, one stands out the most. I was quite wasted, was stumbling about, almost falling over, the world was spinning, I couldn't think strait, and I managed to knock a cup off a counter with my left arm's elbow. Before I consciously realized what had happened, my whole body crouched down, I bent over, and my right arm caught the cup in mid-air.
I've had many situations like this, but this one time I remember the best. To me, it seems certain types of complex reflexes work just fine.
When Ebola made land-fall in the USA, we had something like 9 cases reported. Of those cases, 1 death, 1 still sick, and the rest recovered. Small sample set, but that seemed a lot better than the large death percentages happening in Africa. From what I understand, most deaths are cause by dehydration. A simple IV drip could save a lot of lives.
1 was a rock star.
1 looks like a rock star, but I want references first.
Ordinary programmer maintain status quo, good programmers make the process more efficient. I think "quality" as "non-replaceable", upper echelon. Because everything else is disposable.
If charity doesn't keep up, poor people will turn to crime to stay alive. Then "robbing the productive at gunpoint" won't just be a figure of speech. There seems to be a strong inverse correlation between welfare benefits and crime. Better welfare, less crime. Obviously, better education and decent employment is still better.
We had it easy because we were allowed to sit isolated and build a strong industrial nation while everyone was busy rebuilding just to get back to were they where. When we finally got attacked, it was on a remote island far away from our main land, from another small nation. We hand plenty of time to get ready. If we suddenly removed our military entirely, and let others continue to build theirs, we'd be ready for a darwin award for countries.
May want to read a history book and see how long a country lasts when they have no military might.
They didn't fight to lower taxes, but for their right by law to have representation in parliament. There was also a lot of abuses going on, but with no representation, there was no one to complain to. People where having their property taken or being jailed over frivolous issues and pretty much had kangaroo courts.
But I guess you think we should have just bent over and taken it.
My employer used to outsource overflow to India, where we had a 6 person team at any given time. We stopped outsourcing during the 2008 crash, trying to cut back. We had outstanding bugs that were several months old in some projects, and the code was so messy, it took one of our own about a month to understand the code and fix a single bug.
I was a new one at the time, but eventually we hit one of our annual slow downs and I was given the task to look into some performance issues. One of the first things I noticed was an inner loop that scanned an array instead of using a hashtable. That alone was on average a 10% increase in average performance.
This was a 3500 lines of code project with what has a score of "13" for the "maintainability index" of current Visual Studio. This was several years ago, but I rewrote it in 2 months time, dropping it down to 1800 lines of code and a "maintainability index" of "79", whatever that means. It is now 1000x faster on average, but because of the now O(n) scaling and multi-threading support, it can be a bit faster than the single threaded O(m*n^2) monstrosity it used to be. The new version fixed all previous bugs and ran for almost 5 years before getting its first new bug, which was thread related and took me almost 1 hour to fix.
For all the money they were "Saving" per programmer, it was cheaper to replace all 6 of them with just me, and I got better results in all metrics.
The average GRB converts about 166 Earth masses into pure energy and blasts it out as a laser beam in less than a second. Your best bet is just to keep your distance, not a "shield".
I'm seeing this on the Internet. I saw slightly different numbers from many sites, but they were all nearly the same +- some percentage.

They're working on a "raw" mode for SSD access. Then the wear levelers can be a layer in the file system. FreeBSD is working with some big name SSD companies. Once they have full control of the SSD in software, and all remapping is handled by the OS, it will be possible to have SSDs handle sudden power loss, because the SSD no longer needs to make assumptions that cause race conditions in order to keep everything working transparently for the FS.
ZFS defaults to at least 2 copies of all metadata, but the super blocks are special, so they're replicated an additional time every certain offset of the LBA, on top of keeping the last 256 versions of the super block. You may have 4+ copies of each of those 256 super blocks on a modern multi-terabyte HD by default. A new super block is created every 10 seconds by default, assuming there is any data to be written, this is the "transaction group". It's going to take a lot more than 1 block going bad for catastrophic failure.
A modern integrated Intel 1Gb NIC's silicon with all of the offload features a desktop can use can cost as little as a few pennies extra. 10Gb NICs require their own chips, which are quite large, and need heatsinks. A basic 1Gb switch will consume nearly 1/100th the power of a 10Gb switch when idle. At load, it's closer to 1/10th, but that's not too bad when you realize 10gb is 10x faster, but most home users are idle 24/7. Even when you're watching Netflix or downloading torrents, your switch is nearly idle. My 28 port 1gb managed switch idles around 5 watts at the wall. A basic 10gb switch idles around 200-300. Now there are fans involved, small fans, that spin really fast, and require ear protection to be near. In a house environment, with dust, you'll need to service these switches and their fans.

Sounds like a great way to lose the trust of your child. Enjoy being put in a "home" when you get old enough.
