Re: A Bespoke Emacs Keyboard In Software

I'd really like to learn how you got Hyper/Super in Emacs and how you set it up in macOS. Thank you

Re: Decreasing Emacs Load Time

Alex Popescu — Fri, 18 Apr 2025 15:25:31 -0000

I read the post earlier today and thought I have to try this.
Many hours later I can only say two things:
1) it's very complicated
2) it's not very clear what is the deferred alternative for many :config snippets.
At this point I'm starting to doubt it's worth the effort. Except for learning the good practices of use-package

Re: Unloading Emacs Themes

Alex Popescu — Sat, 08 Feb 2025 13:20:35 -0000

I'll have to post the fragment of code I've put together that 1) chooses randomly a theme; 2) set a light theme during day light; 3) and a dark them in the evening.

The unload part is based on what I researched: (mapcar #'disable-theme custom-enabled-themes)

I can't really figure out what's visual-line-mode doing over the continuation lines (except the lack of the symbol in the gutter).

Happy new year to you too! To a better 2025!

Re: 24 Emacs Packages To Try During The Holidays

Alex Popescu — Sun, 29 Dec 2024 03:36:55 -0000

I'm almost sure this change was not caused by issues with undo-tree, but rather as an "optimization" (less extension code? better integration?)

Re: 24 Emacs Packages To Try During The Holidays

Alex Popescu — Sat, 28 Dec 2024 14:03:18 -0000

In my setup, I have replaced undo-tree with vundo.
Unfortunately I can't find any notes on why.

Re: Emacs Popups In macOS

Alex Popescu — Fri, 18 Oct 2024 13:10:31 -0000

I got it working locally and I will continue to test it.
I don’t have yet a good idea on how to suggest/provided the version with typos fixed.

I just tried to use the code from Grant Rosson's article and it doesn't quite work; parentheses look messed up.

Re: The end of the Redis adventure -

What you created is amazing. The position you took on things related directly or tangentially to what you created has been inspiring to me. I am eagerly awaiting to hear what coming next. Meanwhile my best wishes to you and all dear to you!

This moment made me think back in time... the first post I could find on myNoSQL about Redis is from Dec.3rd 2009 ("Why I like Redis"). Next year you announced support for SQL: https://nosql.mypopescu.com...

Re: WATCHES GIVEAWAY: Timeless Luxury Watches NBCF Nomos Club Campus His & Hers Pair

My favorite so far is the Timeless Ludwig; but the California dial in Nomos Club Campus is very intriguing and appealing.

Re: Sony taking on Beats in headphone market as it pushes more into fashion

Alex Popescu — Mon, 29 Oct 2018 21:39:34 -0000

Are the MX3 able to be connected to multiple devices? Reviews I've read mention that MX2s can only connected with a single device and I was curious if this got fixed.

Re: The Best 4K Monitors

Alex Popescu — Sun, 21 Oct 2018 17:11:04 -0000

The LG models included in the review are 1-2 years old which makes me wonder if there are significant updates in the screens or technologies that should be considered.

I'm leaving aside the price level as that's always subjective element; it's useful for comparison once more elements are known.

Re: I wrote a review of the Ultimate Hacking Keyboard for you nerds

Alex Popescu — Sun, 19 Aug 2018 02:36:02 -0000

I have found myself very much in that opening part on the struggles of having modifier keys away or in different positions then usual. That's the reason I couldn't really get into using the Kinesis Advantage.

I'm very curious how this keyboard will work for you (and keep my fingers crossed it will work given the "investment" :-)

Re: Some thoughts on How Apple could have avoided much...

Alex Popescu — Wed, 02 Nov 2016 01:32:16 -0000

I can fully echo the last part. And I'm almost sure that this fear & loathing of having to find a new home is what's behind the reaction I'm seeing in the developers' corner.

Re: New 15″ MacBook Pro supports four 4K or two 5K displays simultaneously, 13” more limited

Alex Popescu — Fri, 28 Oct 2016 01:21:41 -0000

Am I misreading the description of the dock linked from the article? It says 30Hz for UHD.

"MULTIPLE DISPLAYS: Mac:4K UHD 4096x2160 @ 30Hz, 2K QHD 2560x1600 @ 30Hz & 60Hz Dual Mirrored (MacBook's do not support two extended displays)."

Re: WATCH GIVEAWAY: Maurice Lacroix Pontos S Chronograph

Alex Popescu — Mon, 23 Nov 2015 02:41:38 -0000

I've never owned a dive watch to match it with a suit. But I was always attracted by the Omega watches. Now this Maurice Lacroix looks really good and I'd definitely like to wear it.

Re: WATCH GIVEAWAY: Squale 2002 Collection 1000 Meter Automatic Dive Watch

Alex Popescu — Sat, 24 Oct 2015 12:02:45 -0000

I've always wondered why there are so many diving watches. I mean how many people are actually diving and need a special watch. I assume there is something behind the way we perceive these watches and the message they carry.

You know there's an official pronunciation and continue to pronounce it differently. Why?

Re: The Monopolist

Alex Popescu — Tue, 13 Jan 2015 13:52:57 -0000

The part I'm not completely sure about is assuming the competition relationship being reflexive.

The 2 examples I'm thinking about: 1) MP3 players and iPod; 2) cloud services.

Takes completely separate, in the sense of removing all the ecosystem, I can probably see how for these cases competition is reflexive. On the other hand, at least in Apple's case (MS, Google, Amazon too), it's rarely the case that one can separate complete a product from the ecosystem. And in that case I'd say that competition is not reflexive anymore.

This is actually a similar conclusion of your article, but yours discusses it in terms of transitivity, while my comment is questioning the reflexive nature.

Re: The Monopolist

Alex Popescu — Mon, 12 Jan 2015 02:45:22 -0000

While the rest of the article stands, the mid-part on transitiveness of competition and the example used are incorrect.

The example says that if HTC competes with Apple and Dropbox competes with Apple. Basically that translates to "A competes with B, and C competes with B". Transitivity does not apply.

What I think you are referring to, at least in math terms, is reflexivity: if A competes with B then B competes with A.

Good catch! thanks

Re: Two questions about the Oracle in-memory database

Alex Popescu — Wed, 18 Jun 2014 11:46:17 -0000

That makes a lot more sense to me; the way it was written on the tons of articles I've read before posting totally confused me as hey made it sound like same data can be accessed in an either row or column way.

Re: The era of the No-Design DataBase

Alex Popescu — Wed, 21 May 2014 01:24:37 -0000

Edward, I think you are mixing things up: schema vs query language vs implementation.

If you think about it, not having a schema is almost equivalent with dealing with blobs. That implies quite a bit of complexity for any app that accesses that data (serialization/deserialization, versioning, type checking). Multiply that with the number of apps accessing the same data.

Basically it's another trade-off: initial speed of dev followed by higher complexity down the road vs a more involved ramp-up with a smoother maintenance over time.

The tricky thing here is that while a database that supports schemas can loosen the constrains, one that doesn't cannot help you with the basic constraints needed in the future.

Re: The era of the No-Design DataBase

Alex Popescu — Mon, 19 May 2014 18:32:48 -0000

I think we both can agree that there are various tones of "schema free". At one side of the options we have "complete schema free" (which is actually the my-code-only-schema) and at the other end is "recommended schema with dev & operational flexibility" (i.e. richer data types are allowed, there are some constraints imposed at the level of data types, updates to the schema are not only possible but also cheap from an operational pov).

While the flexibility of just dropping some blobs inside a storage engine is going to speed development in the first stages of an app, I once again think we can agree that the longer the app evolves and the more apps will access the same data the more complexity will have to built into the source code. And that's the time to have the latter option available.
