I'm using cmder on windows, it's pretty and it comes with a lot of unix tools (cat, ls, bash, ssh, more, grep...) and pipes and streams and... I can use vim in the console. Not emacs, vim. I do have emacs on windows but I don't think I can do a
emacs -nw to just use it from the console. So let's go back to learn vim, because I hate being slow. And here is a nice way of doing it!
you can find several pictures of a keyboard aiming at teaching you step by step how vim works. This is all I needed!
I'm digging into the code source of Sage and I see that a lot of functions are implemented with Shoup's NTL. There is also FLINT used. I was wondering what were the differences. I can see that NTL is in c++ and FLINT is in C. On wikipedia:
It is developed by William Hart of the University of Warwick and David Harvey of Harvard University to address the speed limitations of the Pari and NTL libraries.
Although in the code source of Sage I'm looking at they use FLINT by default and switch to NTL when the modulus is getting too large.
By the way, all of that is possible because Sage uses Cython, which allows it to use C in python. I really should learn that...
This implementation is generally slower than the FLINT implementation in :mod:
~sage.rings.polynomial.polynomial_zmod_flint, so we use FLINT by default when the modulus is small enough; but NTL does not require that
`int`-sized, so we use it as default when
n is too large for FLINT.
So the reason behind it seems to be that NTL is better for large numbers.
Silk Road's trial just closed and I ran into this old (?) journal of Ross Ulbricht that contains quite a bunch of interesting passages. I think this will turn into a movie.
server was ddosed, meaning someone knew the real IP. I assumed they obtained it by becoming a guard node. So, I migrated to a new server and set up private guard nodes. There was significant downtime and someone has mentioned that they discovered the IP via a leak from lighttpd.
being blackmailed with user info. talking with large distributor (hell's angels).
commissioned hit on blackmailer with angels
got word that blackmailer was excuted
created file upload script
started to fix problem with bond refunds over 3 months old
got death threat from someone (DeathFromAbove)
withdrawals all caught up
made a sign error when fixing the bond refund bug, so several vendors had very negative accounts.
switched to direct connect for bitcoin instead of over ssh portforward
received visual confirmation of blackmailers execution
gave angels go ahead to find tony7
sent payment to angels for hit on tony76 and his 3 associates

market and forums under sever DoS attack. Gave 10k btc ransom but attack continued.
attacker agreed to stop if I give him the first $100k of revenue and $50k per week thereafter. He stopped, but there
appears to be another DoS attack still persisting
paid $100k to attacker
paid the attacker $50k
rewrote orders page
paid attacker $50k weekly ransom
$2M was stolen from my mtgox account by DEA

red got in a jam and needed $500k to get out. ultimately he convinced me to give it to him, but I got his ID first and
had cimon send harry, his new soldier of fortune, to vancouver to get $800k in cash to cover it. red has been mainly
out of communication, but i haven't lost hope. Atlantis shut down. I was messaged by one of their team who said they
shut down because of an FBI doc leaked to them detailing vulnerabilities in Tor.
Had revelation about the need to eat well, get good sleep, and meditate so I can stay positive and productive.
All of this sounds so surreal. He is making a huge amount of money for sure. A million dollars doesn't seem much for him. He is constantly buying servers and he seems to be coding a lot. He also seem like a normal dude.
And here's a funny thread on who's Variety Jones
I was looking for a way to know what are the real differences between magma, sage and pari. I only worked with sage and pari (and by the way, pari was invented at my university!) but heard of magma from sage contributors.
From the sage website: The Sage-Pari-Magma ecosystem
The biggest difference between Sage and Magma is that Magma is closed source, not free, and difficult for users to extend. This means that most of Magma cannot be changed except by the core Magma developers, since Magma itself is well over two million lines of compiled C code, combined with about a half million lines of interpreted Magma code (that anybody can read and modify). In designing Sage, we carried over some of the excellent design ideas from Magma, such as the parent, element, category hierarchy.
Any mathematician who is serious about doing extensive computational work in algebraic number theory and arithmetic geometry is strongly urged to become familiar with all three systems, since they all have their pros and cons. Pari is sleek and small, Magma has much unique functionality for computations in arithmetic geometry, and Sage has a wide range of functionality in most areas of mathematics, a large developer community, and much unique new code.
I also noticed that Sage provides an interface to Shoup's NTL through
ntl. functions. Good to know!
here's an entertaining piece about NSA backdoors through history: http://ethanheilman.tumblr.com/post/70646748808/a-brief-history-of-nsa-backdoors
1997 Lotus Notes: The NSA requested that Lotus weaken its cryptography so that the NSA could break documents and emails secured by Lotus notes. This Software was used by citizens, companies and governments worldwide.
I talked about this one here.
I'm leaving soon for Chicago and I haven't found the "let's give you a crash course of the city's inside" kind of guide I was looking for. I've also wanted for a long time to write a no bullshit guide on how to manage moving to Bordeaux. So here it is. It's gonna be short, concise and maybe not very ethical.
- avoid the only hostel of the city at all cost
- avoid the kind of agencies where you have to pay a fee (more than 100€ usually) to be able to visit places.
- if you are looking for an apartment during July, August, September... you're in for a bad time. Don't bother finding a real place, just find a sublet for a couple months until things calm down.
- how to find a place? Go on leboncoin (and nowhere else). check "particuliers" to have only landlords, refresh the page and call asap. Always have plenty of documents on you because if you find the place of your dream you might have to fill and sign on the spot. If you don't know what documents you need ask the first landlord you call.
- If you can't have a garant (guarantor) then check out Clé Acquitaine
- need furniture ? cutlery? a bike? Wait for periods when people are leaving: December/January or May/June. People dump free stuff in the streets (really) or sell them for an incredible low price. The Erasmus facebook group of the current year is where it's at. Don't hesitate to bargain, and take your time.
- see the map I posted here? You want to live in the yellow or the orange. The city is pretty small so the other colors should be ok as long as you don't go too far. Never go to the other side of the river though.
- you should buy a bike. Not too expensive because you will probably get it stolen.
- don't pay for a pass, you will never see ticket inspectors. And if you meet one, be sure to have one ticket on you so that you can get a 50% discount on your fine!
- need to go to the airport ? Take the line 1 at Quinconces.
- Never go to KFC and subway. Nobody go there and it's never fresh. Avoid 2€ kebabs. People will tell you about the Coluche being the best kebab place of the city but you will want to avoid this as well. L'Entrecôte and Fufu have huge lines but they are not that special. Go check out Santosha and Pitaya, amazing thaï/vietnamese places.
- check Del'ice n'coffee or Verde Nero.
- iBoat should be a safe bet. Although it might be a bit selective and far away. La Plage is the biggest club I've been in France, it's close to the center, it's free on Thursday and it's full of girls.
- There are quizzes everyday in Bordeaux. Just ask your favorite bars. Avoid Place de la Victoire. Try not to always go to Charles Dickens or HMS or...
- La Maison du Vin. Go to this place. As much as you can. It's cheap, classy and the wine is very, very, very good. Try some Sauternes or some Loupiac or some Montbazillac.
- There are other more expensive places you can drink wine at. Check La Bbelle Campagne or in the same street rue des bahutiers.
- I said earlier never to go to the dark side of Bordeaux (across the river), but you can go if you want to see Darwin. It's a place with many things to do and I won't spoil it for you.
- If you need to buy alcohol late. There is a casino that sells until 10pm near the tram tracks between Victoire and Musée d'Acquitaine. Other small shops Cours Victor Hugo or Cours de l'Yser might as well. After 10pm check around Place du Parlement and you will find some shops selling illegally.
Internet & Phone
- every year in june/july/august/september even november. When people move and need to subscribe to a new internet company, you usually have extremly cheap offers where you would pay like 2€/months for a year instead of 20. Check vente-privee.com this is where everything is at.
- still on vente-privee.com, and during the same periods, you will find mobile company doing the same agressive offers. This is the moment to get real cheap plans. It really doesn't matter what company, they are all the same. Although you might not have a great internet connection with "Free".
You can get the .xpi on the github repo.
Just open it with Firefox and no restart is needed! (
Ctrl+O in firefox)
For now it's very basic. You will see this icon next to the close button:
Yes I know I should create a custom icon :D but I was too busy coding.
You will then see some basic statistics of the day.
I'm now working on making this page nice with pretty graphics and more statistics (week, month, tracking of the most visited website of the week...).
So if you want to try my plugin, know that it works (so far)! And that you should pay this blog a visit because I'm planning on updating it.
A step by step tutorial showing you how to get admin credentials on a windows machine: http://imgur.com/gallery/H8obU
- reboot in start-up repair mode
- read privacy statement of one menu should open notepad
- thanks to notepad replace
sethc 1 with
- so now when you press 5 times on
shift it will call
cmd instead of
- you know have a shell, use command
net localgroup Administrators to get a list of the admins
net user <ACCOUNT NAME HERE> * to change one account's password.
If you're looking for a "fix", microsoft advise you to turn off sticky keys all completely
And here's another exploit for windows 98
Note that as soon as you can access the hard drive, you don't need to use the first trick and can switch around programs in system32 as you wish (except if windows is encrypted with bitlocker). For example you can do this with an ubuntu live cd and swap
cmd with the
magnifier tool and you will be able to do the same thing.
