Anders Live | Build 2016 | Channel 9 – on Turbo Pascal, Delphi, C# and TypeScript

Posted by jpluimers on 2016/04/06

Anders Live - Build 2016 - Channel 9 Stage C907 - Speakers: Anders Hejlsberg, Seth Juarez

Anders Live – Build 2016 – Channel 9 Stage C907 – Speakers: Anders Hejlsberg, Seth Juarez

Anders explaining about being a pragmatist ever since he started working on the Turbo Pascal predecessor in 1981. It’s been a long way to TypeScript and beyond (:

Lot’s of interesting tidbits about the future of TypeScript and how it relates to other languages.

PS:

The Turbo Pascal predecessors were called Blue Link Software Pascal, Compas Pascal and Poly Pascal as I learned last year while teaching a workshop for DAPUG in Denmark when I bumped into some people working with Anders while he still lived there a long time ago. Later I researched the above links.

Cygwin first run and a few aliases

Posted by jpluimers on 2016/04/06

Cygwin first run looks like this:

Copying skeleton files.
These files are for the users to personalise their cygwin experience.

They will never be overwritten nor automatically updated.

'./.bashrc' -> '/home/jeroenp//.bashrc'
'./.bash_profile' -> '/home/jeroenp//.bash_profile'
'./.inputrc' -> '/home/jeroenp//.inputrc'
'./.profile' -> '/home/jeroenp//.profile'

jeroenp@msmxp ~
$

It will copy some default files to your profile so you can modify them.

Since Cygwin will run ~/.bash_profile on logon, and that in turn starts ~/.bashrc (see below), I’ve modified the latter to run ~/.bash_aliases and bring those a bit in sync with my regular Mac machine:


# New user-defined bash aliases file
# Is executed from a modified .bashrc file
# .bashrc is executed from .bash_profile on cygwin
# on other systems, see http://www.joshstaiger.org/archives/2005/07/bash_profile_vs.html
## This is the portion in .bashrc you need to edit in cygwin to enable .bash_aliases:
## Aliases
##
## Some people use a different file for aliases
## if [ -f "${HOME}/.bash_aliases" ]; then
## source "${HOME}/.bash_aliases"
## fi
alias ls-8601='ls -l -T'
alias ls-full-8601='ls -l –time-style=full-iso'
# octal file modes through http://stackoverflow.com/questions/1795976/can-the-unix-list-command-ls-output-numerical-chmod-permissions
alias lsmod='ls -al|awk '\''{k=0;s=0;for(i=0;i<=8;i++){;k+=((substr($1,i+2,1)~/[rwxst]/)*2^(8-i));};j=4;for(i=4;i<=10;i+=3){;s+=((substr($1,i,1)~/[stST]/)*j);j/=2;};if(k){;printf("%0o%0o ",s,k);};print;}'\'''
# silence the progress meter on Cygwin with -sS via http://stackoverflow.com/questions/7373752/how-do-i-get-curl-to-not-show-the-progress-bar
alias whatismyip='curl -sS http://whatismyip.akamai.com && echo'

cURL has some idiosyncrasies, for instance Cygwin shows the progress meter by default, but Mac OS X does not. I wanted to disable the cURL progress meter and you heed -sS for that.

ls doesn’t show you octal file modes by default, but chown and umask use them, so I’ve got the lsmod alias through stack-overflow.

Bash initialisation

Getting your bash initialisation right can be tough. There are lengthy discussions about which .bash* files run under what circumstances:

A future Delphi won’t download start page content from the Embarcadero site

Posted by jpluimers on 2016/04/05

The “Official statement” of Embarcadero about their recent hacks are in the form of comments on public messages mentioning the hacks, some asking to take discussions offline.

They forgot to comment on Delphi: disable or change your welcome page to not use the Embarcadero site (as that site has been hacked twice this weekend) « The Wiert Corner – irregular stream of stuff, so here is their comment from the G+ thread I posted:

FYI: Future versions will no longer have the banner pulled from the website on the start page.

Source: This weekend, the Embarcadero web site was hacked by AnonCoders. once…

I hope it will be the upcoming Delphi 10.1 Berlin version, but given their speed at responding to security threats, I won’t hold my breath.

PS: what a coincidence that I wrote this yesterday on G+:

I know of a few companies that could benefit from more openness.

cURL is not a wget clone (so cannot do mirror) – via: MacNN Forums

Posted by jpluimers on 2016/04/05

Even though cURL seems to handle https better than wget, it is not a wget replacement.

From the cURL FAQ :

1.3 What is cURL not?

Curl is not a wget clone. That is a common misconception. Never, during curl’s development, have we intended curl to replace wget or compete on its market. Curl is targeted at single-shot file transfers.

Curl is not a web site mirroring program. If you want to use curl to mirror something: fine, go ahead and write a script that wraps around curl to make it reality (like curlmirror.pl does).

Curl is not an FTP site mirroring program. Sure, get and send FTP with curl but if you want systematic and sequential behavior you should write a script (or write a new program that interfaces libcurl) and do it.

Aiding parkinson paitients: TEDxDelft 2015 | Mileha Soneji | Empathy is the Key to Great Innovation – TEDxDelft

Posted by jpluimers on 2016/04/04

Her uncle had parkinson. This simple yet innovative solution helped him big time:

she questioned how her uncle walked up and down the stairs.  Surprisingly, he was able to do this without any problem, but as soon as he stopped, he had trouble walking again.  She decided to apply a “staircase illusion” to the floor by having the illusion of a staircase flowing throughout her uncle’s house.  To her surprise, this simple solution was able to help her uncle move around the house faster and easier.

Tools that Isotopp installed on his Mac…

Posted by jpluimers on 2016/04/01

IRC so: »i> Isotopp: Ich habe jetzt nen Mac als Arbeitsplatzrechner… Was will man als UNIX Hacker zuerst an Tools installieren?«

Source: IRC so: »i> Isotopp: Ich habe jetzt nen Mac als Arbeitsplatzrechner… Was will… by Kristian Köhntopp.

Since G+ is very bad at searching, I created this summary of the tools; read the full G+ post (Google Translate is quite OK), including comments on why.

Edit: 20160402 – I’m posting regular updates based on the comments for that G+ post. I’ve changed or added German iTunes store links to US-English ones.

From the #alleskaputt -Dept: Hotel, Internet of Shit Switches, Predictable IP… boom!

Posted by jpluimers on 2016/04/01

From the #alleskaputt -Dept: Hotel, Internet of Shit Switches, Predictable IP Addresses (== Room Number) and no security. Right. – Kristian Köhntopp – Google+

referring to: mjg59 | I stayed in a hotel with Android lightswitches and it was just as bad as you’d imagine

And then I noticed something. My room number is 714. The IP address I was communicating with was 172.16.207.14. They wouldn’t, would they?

Then you get this:

Official Gmail Blog: Introducing Gmail Mic Drop – April 1st retracted because of too much of a success

Posted by jpluimers on 2016/04/01

The Mic Drop button worked so well (besides confusing the heck out of many people, it sometimes even got activated while sending a normal email) that GMail has retracted their April 1st joke.

What a prank (:
