Comment Heavy? (Score 1) 215

The Nokia 5100 from 2003 wasn't heavy. Check the specs at https://en.wikipedia.org/wiki/...

It's 104 grams.

2007 iPhone: 135 g https://en.wikipedia.org/wiki/...
2011 Samsung Galaxy S2 116 g https://en.wikipedia.org/wiki/...
2011 iPhone 4S 140 g https://en.wikipedia.org/wiki/...
2015 Samsung Galaxy S6 138 g https://en.wikipedia.org/wiki/...
2015 iPhone 6S 143 g https://en.wikipedia.org/wiki/...

Phones got bigger and heavier, which is not a surprise also considering all the new stuff that got packed inside vs the feature phones era.

A social push for metric units? I can't see it coming. The best chance for metric in the USA is China becoming the dominant economic and military power (if it ever happens.) Then the USA must sell metric based stuff and services to them because they won't accept imperial units. There won't be any changes until the USA is the number one country. Scientists and some engineers will keep being "bilingual" (metric at work and imperial at home) and that's it.

How are chimps, gorillas and Co faring against those ape superintelligences called humans? Still alive, but some in zoos, others in labs, all of them progressively stripped out of vital space due to the exigences of their more intelligent cousins. I won't like to go the way of chimps so it's ok to develop some special purpose AI (vision, driving, etc), but I'd be very wary of connecting all the pieces together. It won't behave as a servant no more than we are servant to cats, no matter if cats actually believe all that infrastructures we built are for letting us be better caregivers to them

I have a small 32 GB SSD on this laptop (I keep the OS there) plus a 750 GB spinning disk (data). The swap space would have been on the HD (I think swapping to SSD is bad because of write amplification) so I could have made it as big as I wished. However I decided to go without swap and see what happened. After more than one year I didn't have any problem. Even if I didn't hit max memory once I'm pretty sure the OS would have swapped out some programs sometimes because it makes sense to move out inactive programs to make space for buffer cache (it's Linux and I saw it happen in the past) but with so much RAM I don't care about 1 GB less of buffer cache. I prefer to have programs respond quickly after a couple of days I don't use them. I was constantly hitting swap to some degree on the old 4 GB laptop and it wasn't pretty. Obviously I didn't leave programs around much. Firefox, Thunderbird, emacs, terminal always open, the other programs on demand.

I had that kind of problem until February 2014 (old Core Duo with 4 GB RAM) then I bought a new laptop with 16 GB upgradeable to 32 GB. No swap space configured. I keep leaving all sort of applications open (4 virtual desktops) and sometimes I got down to 3 GB free and started thinking about the extra 16 GB. Well, not until I'll really have to work with some VMs open all the time.
4 GB are not necessarily too little nowadays, but one should expect to be careful with the programs he runs. Like Android phones with half a GB of RAM.

Not on my Firefox 38 on Ubuntu. I copied the URL of this page, mid clicked on the new tab button and got an empty tab. I checked the preferences and I didn't find anything relevant (but I noticed that they are web pages now, not a dialog anymore - big surprise!). Maybe it's browser.newtablurl set to about:blank in about:config? No, it isn't that one because I don't get that behaviour with the default value too.

Comment Proxied ads (Score 2) 198

The workaround will be to proxy ads from the server. I bet that the ad networks will develop the technology for all the major frameworks. That will hurt servers' bandwidth, threads and CPU but it will make harder for ISPs to block ads because the URLs won't give away much. Unfortunately that will make the job harder for in-browser adblockers too so I don't welcome that move. I bet we'll end up with the same amount of ads and less ways of blocking them.
BTW, how are they going to deal with https? Are they going to block the IPs of the ad networks?

When I'm ssh-ing to a server I can usually tell the difference between WiFi or Ethernet. It seems that WiFi isn't good at sending many small packets (one per keypress) quickly in a crowded environment. At home I always connect my laptop to Ethernet unless I'm using it on the coach.

I always plug my laptop to the main and I use a USB drive once a day to back it up. Luckily it's got 3 USB ports and a separate DC port. I won't have any problem doing a backup on battery power but it's not likely that I'm doing it on a train :-)

Comment Re:Memorizing site-unique passwords isn't possible (Score 1) 267

First, you should not use somebody's else computer, Internet shop included. Use your phone or tablet over https if possible.
If you really can't do that, use a local password manager like KeepassX on your phone and copy the password by hand on the computer. You compromised only that site. However this can be extremely painful if you use fully random password like g27rkuqhLJcM46G9YsxV4rlF9ACtveB1. These are 32 characters with only letters and digits to limit the typing errors (think about entering punctuation on a very foreign keyboard layout). According to KeepassX its strenght is 191 "quality bits" defined as the "equivalent size of a random symmetric key."
If you use an Internet password manager on an untrusted machine you run into the problem you described and all your accounts are compromised.
By the way, assuming that passwords are stored as SHA-2 (64 characters) should we use 64 characters passwords to minimize the risk of collisions?
