This can easily be done with a small shell script and standard linux commands. #!/usr/bin/bash MAILTEXT=$(grep "dbkey" db.txt) cat emails.lst|while read ADDR NAME do mail -s "Subject

Another reason is that farming machinery compacts the soil. Techniques such as min-till and no-till aim to minimise soil disturbance (to reduce emissions from deep ploughing and improve soil fertility), but to achieve this you really need t

grep has a bad interaction with set -e, since it (infuriatingly) exits with 1 if no lines are matched.

I remember back in the day these were used by the A86 assembler to identify code assembled with the unregistered version of the software.

I think it was because in the 80's the US was wealthier and systems with disk drives were a lot more common. People would swap games on disk, and there was less pressure to learn how the underlying system works. Having a disk drive als

The thing I miss about Usenet is maintaining article and comment scoring in trn (based on the subject, keywords and/or author) With this I could easily surface interesting articles or replies by insightful people, while avoiding subjec

I'm curious - are there any features of System/360, that we don't have in modern operating systems, that would be worth implementing?

1) The contracting scene in the UK is massive, that's where a lot of the higher paying UK tech jobs are. I suspect this skews the salary averages. 2) I'm in South Africa, I've recently been approached on linked-in to (quote)

It's not really a conspiracy, just the natural outcome of design optimization - any part that still works reliably at the end of the design lifespan is a candidate for cost cutting in the next iteration.

Ben Eater's Youtube series building a simple CPU from scratch was a real "lightbulb" moment for me. After 40 years of programming (including Z80 assembly back in the 8-bit days), it took my understanding of the CPU from a mys

What I find fascinating is that Lisp, commonly perceived as too high level to be practical, is actually at its core (in its original implementations!) an incredibly low level language.

The problem is latency, which actually will get worse as bandwidth increases. 1 request pulling down 1 Mb can be quicker than 4 requests for 10Kb each.

Typically an architect's design would need to be signed off by a structural engineer before construction begins. The structural engineer would take on the liability for safety critical aspects of the design. The architect and engineer

Use my new app! It's a special folder. When you put an app in the folder it will DELETE the app from your phone and store it like a symlink. When you try to open the app from the folder it will install it again for you. Think of all th

Double that to get the agency rate, and no one wants an app completely designed by juniors, you'll need at least one senior resource and probably a PM.

Eros and KeyKOS had some very interesting ideas in addition to capabilities. Global process persistence meant that you could pull the plug on a running system and start it back up right where it left off. It was constantly journalling syste

Interesting. I wonder how does this compare to: 1) Buying every month 2) Only buying at some set period after each correction (e.g. market drops x% over 7 days). Are there any online tools that make it simple to work out these ideas?

I think that in most large companies the efficiencies produced by economies of scale are mostly captured by the management hierarchy (in terms of executive compensation and the support apparatus provided by consultants) And why not? - the m

I'm not so fussed about ads I can ignore, but (along with analytics and stuff like social media buttons) - they all add latency to web browsing with extra DNS lookups and HTTP requests. It's especially bad on mobile. So no matter

You know, you're right - that does sound a lot like Erlang. Which is generally considered an extremely pragmatic language. I guess it all goes back to the Actor model and the origins of OO in Simula.

I'm starting to think that different programming styles are more suited to different levels of abstraction - maybe you can program in an OO style at a high level, use functional style code for the low level implementation.
