Comment Re:Most of the web really sucks (Score 1) 325

Instead, all browsers do the same stupid thing - try to load all 30 images at the same time, leaving you sitting there looking at 30 partial images.

On a higher bandwidth connection this would be faster. Loading small (say, 100KB) images on a connection where there is high ping to the server (say, I have a fiber optic connection, but the server is on the other side of the planet)in series is slower than loading them in parallel, because of the time spent waiting for the replies (setting up the tcp connection etc).

I also remember download accelerators that would split up a file in multiple parts and download them in parallel, this would usually make the download faster even if all pieces came from the same server. Also, iperf -P10 is usually faster than iperf -P1...

Of course, on a very slow connection, loading multiple images in parallel is worse because each session is competing with the others for bandwidth and the downloads may time out.

Java applets(much rarer than they used to be

It seems to me that a lot of servers use Java for remote management (IPMI, ILO, DRAC...), either for everything or just remote KVM. Some networks switches (D-Link for example) also use it, at least for the live monitoring on the web interface.

I rarely see Java used on the public internet though. Still, I guess I'll have to stop updating firefox so as not to break compatibility with the Java stuff that I have to use.

Java already whines enough, no need to add even more inconvenience.

As for input lag, for me, if I set a non-game mode, it is severely noticeable even when moving the mouse (bad enough to make it difficult to click on a button). It also is present when watching an analog source. Enabling game mode removes most of it, however, other modes allow for better picture quality, hence the audio delay device.

To me this set will be good enough, I guess by the time it breaks beyond my capability of repair, flat OLED sets will be affordable or I'll buy a projector.

I bought a plasma TV too, but its blacks are much worse than any of the CRT TVs and monitors I have. When a CRT is displaying black, it looks like the device is off, while I would never mistake my TV displaying black and being off (though it does turn off if you give it a full black picture, but place a tiny dot in it and the whole picture becomes gray). I read that there is a way to fix it by adjusting the power supply voltages, I have yet to try it though, the warranty has expired recently, so I will probably try this.

OTOH, this big 10cm TV is better than my previous 82cm HD ready CRT. Analog SD sources like Laserdisc or VHS also look good. Except for dark scenes in movies. Watching it in the dark makes the lack of proper black level very apparent. Watching it with lights on makes it annoying because the screen is so reflective.

In addition, it has quite high input lag if I enable any of the video features (or just set the video mode to anything except "game" and sometimes even "game" mode has lag), I solved this with an audio delay. Delaying audio for 240ms makes the image sync up.

To me, physical media is more convenient when used in a car etc. I select a few tapes or MDs to take when driving somewhere further away, then listen to them while driving. Out of that small set, I can choose the next tape very quickly and without taking both eyes off the road. If I had half my music collection on a single medium, I would have to go trough menus to select the next album to play or would have to memorize a lot of track numbers.

Also, I already have a lot of cassettes. Recording them all to digital storage would take a long time and would not necessarily be more convenient after that.

As I understand, he again removed the funding from foreign organizations (that is, the USA does not have to fund them at all anyway, but does so out of good will or for publicity) that offer abortions. As I understand, this is what all Republicans do when they assume office and all Democrats reverse it when they assume office.

I think that abortion should be legal to anyone, but should only be paid for by the tax payers if it is needed to save the life of the mother or if the mother was a rape victim. Otherwise - pay for it yourself, I do not want to pay for the result of your conscious and consensual act (after all, you could have used protection etc).

Just like I think that the government (I live in a country with national health care) should pay when somebody has to fix his tooth, but if you just want to make your teeth look whiter or implant a gold tooth, then you get to pay for it yourself.

No way, and your ISP will love the data cap overage charges if you try.

Depends on the ISP. I uploaded ~100TB last 31 days, no overage charges from the ISP. Still, I would not want to put my backups on a server I do not control.

I am thinking about tape, I used tapes in the past for archiving, it is not that expensive (not the latest gen, but I do not need the latest gen, currently all my data would fit on one of those 16TB drives, though my storage server uses raidz2 of 3TB drives) and since my data does not change much, the tapes could do double duty as archive (I certainly would not need to do a full backup very often) and have the advantage of being completely offline when not in use.

However, for now I cannot figure out a convenient way to automate all this (incremental, differential backups) on Linux. In the past my storage server was Windows and I used Windows software to do this, but now the storage server is Linux (and zfs) and I would like to attach the tape autoloader to the server.

Or, I guess I could get a small backup server with a few of these drives in raidz2, but it would most likely be more expensive than the tape autoloader with 20TB of tapes.

So that I do not need to buy new drives every time I want to add a file.

Also, when there is not that much free space left, zfs fragments badly, resulting in slower speeds. A slightly bigger hard drive (or more of them) is usually cheaper than putting the entire storage on SSDs, especially if I do not need the SSD speed.

As long as no water is leaked never replace the pipes.

Tell them that SHA-1 is the same as a lead pipe and IE6 is the same as a radium pipe. They may not leak, but it also may not be very healthy to drink the water that has been trough them.

However, some of the requirements are not reasonable. I agree that IE6 is really bad, but in some cases it may be running on a device that costs a lot to replace.

Is SHA-1 weak? Yes. But in some cases it may still be good enough. AFAIK, SHA-1 is weak against collision attacks (creating two messages with the same hash), but strong enough against regular attacks (create a message that produces a specified hash). So, if I use SHA-1 for authenticating VPN packets (quite a few devices do not support sha2), it should be good enough, since the attacker would need to change the encrypted packet such that it 1) matches the MAC and 2) is decrypted into something useful for the attacker.

Hey, even cracking a salted MD5 hash (to get the password) is still quite difficult.

This is different to the attack of me producing two contracts with different text and the same hash and then having you sign one of them, but later claiming that you signed the other.

Security and convenience (and cost) are opposite of each other. Because of this, you have to find a reasonable level of security.

meanwhile when you run yum or apt, it sends an HTTP request for each individual piece of software you're updating or installing back to a central server

I can download the whole repository and run my own mirror if I want to. Then whatever software I install will only be visible in the logs of my server.

Actually I do not really care about that. What I care about is Microsoft having access to my files. The way the privacy agreement is written it implies that Microsoft does have access to my files and is willing to let others have access too.

This is what I care about. I can disable Cortana, never use the Windows Store or OneDrive, that is not a problem. But Microsoft having access to my files is a problem.

Every keystroke you enter into your browser's search bar is sent to a remote server, where it's logged in Web server logs.

The difference here is that I know I am putting info in the search bar and that it is going to be logged at least by one server. My ISP (and all companies that control the routers between me and the destination server) can find out where I am connecting. That does not matter.

It's the difference between having your phone wiretapped and your room bugged. When I talk over the phone, I know that the conversation is going over insecure channels and I talk accordingly.
