Better Bash Scripting in 15 Minutes Some fantastic tips. I write a LOT of bash scripts and I didn't know many of most Kamagra Australia of these. At the end he concludes with a useful list involving "signs you should not be working with a bash script".
Welcome Shane Madden to StackExchange! I don't ordinarily link to my own writing, but I make an exception for this one. I have got a new coworker at StackExchange in addition to here is our blog publish about his arrival.
Rate limiting State If you use ISC BIND, you actually probably know Paul Vixie. If you run any DNS web server you probably want to read his brand new article about DDoS attack mitigation. "The exciting thing about huge data is not that it can be big."
Some things I learned this month:
When less is displaying a file, you may type S and it Kamagra Nz will start acting as if you had given of which option at the command line.
In Mac OS X, you can sort open R foo and it will display file foo in the finder pre selected (when if you had single clicked it). You can now simply drag it to a GUI based app.
MailChimp is actually pretty awesome. I'm thinking of doing some sort of monthly mailing about my book projects. If you'd like in order to join, give me your contact bits.
Within VIM, gqip reformats the current paragraph. I had been using !}fmt
Heartbleed has reminded me what equipment and products I deal with that are difficult to upgrade. While most people think of DevOps as "rapidly deploying software that your coworkers wrote", it is really about creating a world where we are able to make changes. because change is required to experiment, and Kamagra Oral Jelly Nz innovation requires experimentation. and that means being able to make changes. This includes not just in house software releases, but all operational changes we do. This includes software and firmware releases we get from vendors.
My new( ish) job at StackExchange has me actually touching hardware instead of living in the virtualized, everything is done for you, world of Google. All our networking gear is Cisco. Most of it is upgraded only when we have to.
I used to upgrade Cisco firmware in the 1990s (well, up until 2003 I guess). I figured, "How much different could it be?" (Wow, do I feel old for saying that).
The process hasn't changed much. It is still TFTP firmware from a server. The version numbers are all different, and much more complex selection process, but I can deal with that.
However I'm shocked that there isn't a Windows app that just does it all for me. Something where I enter the IP address of the router, my username and password, and it says:
"Hi Tom! It looks like you have a Cisco Wizbang 7600 running version 6.4.1.2.3.5(2)! The recommended release for this device is:
If you are conservative: 7.4.1.2.3.5(2)
If Kamagra Gel you live on the edge: 7.6.3.1.4(123)
If you are insane: 8.0.0.0(0)
Then I click on one of those 3 and it just freaking does the right thing: Gets it from Cisco, uploads it to the device, asks me to confirm and reboots it.
Hasn't anyone thought of this before? It seems so obvious.
I talked with my friends at Cisco and they told me that the "Prime Infrastructure" product does this but it is one feature out of a huge, expensive, product.
Why hasn't there been an open source project to do this? It seems so obvious.
It's two parts: Helping choose the version and upgrading the firmware. The first might be difficult unless Cisco provides an API to their vast sea of IOS versions. I can forego that part for now. The second half seems to be pretty straight forward. Half of the code is already in RANCID.
I'm not a network engineer so maybe this already exists.
Post a comment if you know of one.
The train station that is at Newark Airport is being repaired and is therefore shut Buy Kamagra down. The dates of this scheduled maintenance coincide exactly with the conference. Sigh.
As a sysadmin, I appreciate the need for scheduled maintenance Kamagra Oral Jelly and appreciate that it was announced in advance. At least this isn't catching us by surprise.
