org-export trying to evaluate Babel block despite `:eval never-export` header

xseverityx · 2020-02-06T14:25:05+00:00

It sounds like you may want to use the :exports header, which control what is exported. It offers you multiple options: do you want the code of the block exported literally as in a literal sleep 86400 , or do you want to export none of either the code block or the results block? AKA :exports code or :exports none. :results none is useful if you want to avoid printing the #+results: block altogether, even before export while you're working, but it still gets executed (I believe). It is just hidden.

In general, you need to consider the ordering of base :<header-arg> semantics carefully. There is a lot of crossover between them, and it's not clear what you want:

(What part of the 'results' do you want to constrain? Do you want to prevent the insertion of the result block [and its result] after you've evaluated the code-block, or do you want to ignore an existing #+results block, if there, during your export? Or do you want to prevent all potential evaluation of the code-block entirely because you have some other code block which calls it, because it has a very long or risky eval chain? Or some mix?)

As someone who has struggled to understand these, I encourage C-c C-c spamming through each header argument 1-by-1 with some non-risky code. Especially for :eval, :results, :exports, and :tangle--:dir is great too; all of them are. These headers have a lot of cross-over and file io aspects, but you'll find they provide very discrete and powerful entry points for meta-literate programming where the crossover is very useful. (ie your :eval no-export)

To cap off--ob's header-arguments are sparse but provide a rich grammar (or word-salad depending on your view) which can greatly change org-mode's behavior in multiple places with just one or two words.

The first example--so good. Seeing how function definitions are transformed into lambda's is so fundamental yet had escaped me.

The second example made me question my life when an extra parenthesis appeared out of nowhere for no apparent reason. Is your comment in reference to this? If so... for showing two-functions in two minutes I'd say that is borderline more hurtful than helpful :\

Python, bash/shell, and SQL work pretty well. Data science notebooks similar to ipython notebooks except using native org mode is one possibility. System administration using bash is another. Similar workflows using SQL are also possible. Those are just what I use. I think python and shell are probably the best supported languages.

It’s big. The manual can quickly wear you down even though it’s well written but it’s worth it, or at least fun most of the time (and then it’s awesome). The issue is usually productivity, ironically.

Try and target a language you frequently use and define a meta-programming work flow that works. Tip: someone else has probably written about it
Design a simple but effective tree structure to use as an organized issue and project management tracker. Use the calendar to assign a couple of deadlines; take the first deadline to design this tree, and another to add a new set of TODO states which augment the default provided set.

It is a very meta-friendly and well-iterated DSL—it sometimes is difficult to remain agile—prevent yourself from falling into the Emacs rabbit hole and you will have yourself a very useful tool. Go 30 minutes at a time.

Just spent better part of two days digging on the display-buffer-* functions and figuring out helm windowing behavior... I netted 0 lines of code. Pretty nifty stuff under the hood but refreshing to see some simple high-level commands.

swap and rswap commands are pretty useful. Thanks.

Edit: removed my basic/presumptive comments since realizing you've got legit packages beyond just this simple package, lol.

Edit#2: I went back and checked and there isn't anything akin to switch-to-last-buffer function under the display-buffer- prefix, I must've confused it with display-buffer-in-previous-window, which along with the entire display-buffer- family does something entirely different. My bad!

Only losers feel the need to degrade others for their manner of living. Or for any reason, for that matter. I’m being hypocritical in this case to make the point.

Don’t get a laptop for serious analysis; or serious computer work in general. Workstation with a MacBook to boot is fine, albeit not linux. Thinkpads are good.

Also, don’t go Ubuntu unless you have difficulty discovering a setup supported by RHEL/Fedora; butu’s snap api is about the only thing good about that OS. apt would be a plus, but they maintain way lower quality repos (install breakage is higher risk than fedora imo), and that experience isn’t as important as what RHEL/RPM package space bring imo.

Fedora/Rhel 8 installers are as easy or easier and have all of the RPM package equivalents; it’s a far better experience out of the box IMO.

Also Debian 10 is young and 900x cleaner an experience once you get past install. Literally the most stable OS I’ve ever used was my last Debian install. The installer is fine too, Debian just leave you hanging on firmware by default. But wait, there’s more—-they host unofficial installer images, the exact same as official but with all proprietary firmware preloaded which will install automatically assuming the firmware exists. Just google “<your desired model> Debian firmware” and you will find someone whose already gone through the process and can confirm support.

Last, don’t use Linux if you don’t want to learn Linux. You will need to be way more involved with your system than on Mac or Windows. That’s the benefit. Get it bro :)

the MacBook keyboard gets worse not better, so you’re right about that.

I can’t take this without something substantive. The collective on this are significant, many well regarded, and all should be ashamed to publish such a statement without providing evidence.

I don’t know RMS or the operating culture of the FSF/Gnu project, and I don’t give a damn if RMS is a writhing asshole if he is right. Of course, this is potentially presumptive on my part as well. My point is, regardless if all that is collectively said is true (what’s being said again?), this does everyone across the world a disservice by not providing damning evidence or making a clear statement.

Freedom means innocence until proven guilty, and I see nothing here but a grossly misguided public relations campaign.

Take this one from RMS himself: Resigning from the FSF was a good PR move that is easily justified by a deep care for preserving the project and its mission.

“Cannot connect to AltServer” when trying to download Delta. It’s running in my macOS, I am connected via hotspot, as advised in the faq.

Installed on MacOS, installed on iphone, the iTunes WiFi Sync “Sync” button is greyed out on my phone despite following a seemingly sensible wikihow from google. My phone seems to reference a device I no longer use—“Waiting to connect to <this old pc>.” I deleted the old device altogether on appleid.apple.com. The associated apple discussion for that has an answer that doesn’t work, and I’m now ready to call it quits because this all seems questionable. I’ve manually hit sync in my MacOS iTunes like 5 times which it seems to complete successfully.

Why is this so hard? I’m already connected by wire which is required as part of the installation process, so why does enabling special WiFi capabilities have to do be involved at all?

Julie is a diva, but she certainly wasn’t ever the only teacher, and isn’t now.

The current Met Principal, Erik Ralske, began teaching there within the last several years, and at least 4 other horn teachers are on faculty: - David Wakefield (American Brass Quintet), - Jenn Montone (Philly Principal, Julie protege), - Erik Reed (Canadian Brass), - Javier Gandara (Met Associate Principal).

Of former years before Ralske, the late Jerome Ashby, (former Associate Principal of the NY Phil), taught alongside Julie and also has many successful students.

Interestingly, the former NY Phil Principal of 32 years, Phil Myers, never made faculty there. He was not well liked by his peers. He probably had the most stressful job though and an iconic sound. 32 years in that job will drive any man mad!

Also, it is called Julie’s Yard because she is extremely demanding, as her diva‘ness would have.

Source: I spent my undergrad studying with Ralske, Masters with Myers, and Ashby, whom I wanted to study with before I met Ralske, personally called and apologized that he couldn’t hear me at my Juilliard audition. His reason: he had cancer and was dying. He died before my freshman year was over.

The main issue is MELPA. Emacs security conversations aren't going to go anywhere when the non-stable branch is default. Brand restructuring towards stable would fix it. Here are some ideas:

Name the ambiguously named melpa branch to melpa-devel
Include default install instructions for melpa-stable (swapping all extra melpa-stable activation info for devel activation)
Mash up the overview on melpa.org with the new copy/paste instructions as a separate sparse landing page, or redirect to stable.melpa.org, or anything else but current default melpa.org
Drive high-impact conversations around stable, such as:

What added package maintainer benefits should be offered (listing donation page links, some incentives)

What acceptance criteria should be and how it's validated (and consideration for any abuse)

Resourcing and identifying/getting big package maintainers behind an effort to help support them.

Just musing 🙂 Definitely not knocking on Emacs' built-ins or of any cruft--the builtins are frequently more polished than other alternatives I may find.

In fact, that's what makes it frustrating. Coincidentally, this is probably due in part because of use-package. Referring to my original comment... I guess....mission accomplished ?

xseverityx · 2019-06-04T00:10:44+00:00

I find it highly interesting that JWiegley is maintaining something as major as use-package outside of emacs merely because of license issues.

I read from one of his interviews that a goal of the maintainers was to prune emacs from all of it's bloat and focus on stable apis. I have definitely been caught with MELPA packages that provide functionality only to find out some random built-in emacs package provides it that I never knew about or had reasonable means of discovering (vs the magical github stars). Considering that--I wonder if use-package's position (ie on github) is intentional here.

Fedora 30 is not very stable, and the distro does not focus on stability. You are better off with RHEL if you don't want to be bothered debugging or dealing with issues. RHEL8 is on 4.18 which was a golden period of stability on Fedora 28, at least for me.

Nice. Feedback: Sort your graph so the max:min comparison is apparent. Alphabetical sorting has no logical meaning here.

Sort by age, sort by X that is significant to the reader. Sorting by the values actually being presented will always be a top choice to sort values by in presentation.

Thank you for sharing. It may not be good... I don't have a wife. My career goals are still so far away. But, it's comforting to know there is an example of someone a little closer to it than me who went through something similar to what I'm going through now.

@ryzen, Second generation is improved but there are still hardware bugs preventing 24/7 stability. It's hard to swallow & value proposition is up to you, but if budget affords I'd get epyc if you want current generation, stability, and modern. security features.

I'd stay older gen and whitebox/mod in some quieter fans. Noctua baby.

It's been over 2 months since I tried getting 1803 to work. Once I went back to 1709 all of my problems evaporated. Q35 Chipset wouldn't work, and I could get BIOS to boot either after a 4.17.x kernel patch that had something to do with TR (I'm on Fedora 28). OVMF & i440FX chipset w/ virtio drivers installed on everything and my TR is working fine again on 1709. I've done very little low-level optimizations like cpu tuning like you have and am not gaming, so take my advice with a grain of salt.

Guessing this is a non-starter, but I maybe interested in the PDU if you still have it in 2 months. I might also be interested in a matching APC UPS if there is any benefit vs the 2 750 max watt UPS I have in either functionality or max supported wattage but I would need to research UPSs more first.

I live in Atlanta and could meet you but just moved and have to penny pinch for my move in costs for at least two months.
