A very powerful tool for text manipulation under *nix systems is VI [Short for Visual]. I started using some 5 years ago, and it rapidly became my favorite text editor of choice under linux/unix and I use it on the windows platform too as gVim.
I’m not going to start explaining its power, I just want to share a VI cheat-sheet I found a few months back when I was working for Faculte.
The first image is the entire Cheat Sheet, and the rest are the training sheets for different actions you want to perform while text editing. So? How do you like it?
I stumbled on to an IPv4 depletion counter a few weeks ago, and that reminded me of the problem we are going to face in a couple of years. The crippling of the internet as we know it. Lack of IPv4 space will break a lot of stuff, starting from you watching HBO online, you getting your email delivered, your comics, and your Viagra spam mails. Even if not getting the Viagra spam mails is a good thing, we will still face a lot of hard time, ahead. That I can promise you!
Big players don’t have any interest in training their people to handle IPv6, or to handle dual stacking, they are not building their gadgets to support IPv6 yet, because it’s still far far away, but their costs will jump from a normal normal curve to a very steep one just because they did not plan ahead.
It’s only 96 more bits, it’s not magic, but someone has to know how to do it. If you have no clue about what I just said here, watch the interview below and ask your system administrator about it. If you are the system administrator, watch the interview below, start asking for funds and time to work on it but most important start dual stacking. Slowly, gently, get your experience with IPv6 otherwise you’re gonna pay the big bucks in the end.
Randy Bush on IPv6 Deployment
IPv6 provides enough addresses to allow the Internet to continue to expand and the industry to innovate. It is not, however, directly compatible with IPv4, meaning that a device connected via IPv4 cannot communicate directly with a device connected using IPv6.
Deploying IPv6 on a global scale is vital to the Internet industry, but it requires pro-active steps on the part of industry players: technology must be upgraded, staff trained, business plans developed.Â Uptake to date has been relatively slow, but this is now changing, and businesses need to be aware of the need to adopt IPv6. To ignore IPv6 is to risk your medium to long term business viability.
Ripe NCC built a website with a lot of starting points for deploying IPv6 at http://www.ipv6actnow.org I suggest you take a look at it, watch the interviews and start preparing.
Friday the 22nd Douglas â€œThe Bearâ€ Hazard sent a mass message trying to get out the word about some disturbing facts about SMF [Simple Machines Forum] an open source forum software that started sometime ago. I will not go into details here, because they have a full explanation of what happened here.
If you ever used SMF, take the time to read the article and try to help these guys spread the word out because one good piece of software is on the brink of extinction right about now.
If you never used SMF, but you are using a forum software that does not meet all your expectations, SMF is for you, but first, read the article, and help the community develop the software further.
Via Amec, zie “maghiarian” freunden, we have a nice joke today about the history of our medicine.
“I have a sore throat.”
2000 BC : “Eat this root” 1200 AD : “That root is heathen, say this prayer.” 1500 AD : “That prayer is superstition, drink this elixir.” 1800 AD : “That elixir is snake oil, Take this pill.” 1900 AD : “That pill is ineffective, Take this antibiotic.” 2000 AD : “That antibiotic is artificial, Here why don’t you eat this root.”
Most of you [geeks like me]Â probably know about the new computational search engine Wolfram Alpha which delivers answers based on facts rather than on search strings.Â [There you go Google, now you have some serious competition!]
They are able to compute quite a few complex answers, delivering correct answers for correct questions.Â
For example, they are able to tell me the distance from one remote town in Romania to some other remote town in Japan, or in the US with interpreted distances, and travel times by different means of locomotion like this orÂ this.Â It can tell you how many calories you had for breakfast if you use it like this,Â or compute a sumÂ together with its limit divergence/convergence, function graph etc.Â and many many more type of queries are available on their example page.
The funy part was today when I asked it about my birthdate, and I got the results in the image below.Â
