Sportem ku zdraví, říká se. A k trvalé invaliditě, dodávají jiní. V případě horolezectví to ale může dopadnout mnohem hůř. Všechny ty světově známé vrcholky mají svůj smutný seznam těch, kteří padli při jejich zdolávání. A pochopitelně mezi nimi nechybí ani ženy.

In the wake of the devastation rendered by Hurricane Helene, Carolina Furfare released a newsletter on October 1 stating the cancellation of the event that was to occur this weekend, and indicating that the hotels and facilities were needed in order to assist with rescue and sheltering efforts after the Hurricane hit the mountainous region.

This weather event hit the top ten most fatal and costly hurricanes in the United States even before full recovery efforts could be finalized. People who pre-registered have been given the option to roll over to next year, or to Bewhiskered 2025; due to the cancellation being so close to event day they cannot guarantee refunds for now.

Our Republican leaders don’t believe they have the authority, they don’t believe they’re legitimate, they don’t see the threat. They don’t want to see the threat because they know they can’t face the mob. They know they’re too weak. And so they offer trinkets and hope the mob will go away, but it won’t. Mobs can’t be sated. We thought Republicans understood that. That’s why we supported them. But this crisis has revealed the truth. Now we know who they are. It could not be clearer and now it’s time to find new leaders. Continue reading →

Republicans are failing for a much more obvious reason, a more fundamental reason. They're failing because they haven't done much that is worth doing. They haven't tried very hard to improve your life. When the crisis came, they fled. They did nothing to defend you. They did nothing to defend the country. Continue reading →

Henry Barajas' Death To Pachuco , a Chicano noir set in the Zoot Suit Riots, is now live on Kickstarter

When I was an undergraduate at university many years ago, my deep enjoyment and love for the works of William Shakespeare blossomed. I had the privilege of taking a Shakespearean class and then during one summer in my undergraduate years, I was able to travel through Europe inexpensively on a bike and a Europass to see the great sites. A memory I remember most is going to Stratford-upon-Avon and watching a William Shakespeare play. I don’t know where my passion and love for his plays comes from but it has been a deep part of my life. His writings have also taught me many things.

When I was in England many years ago for the first time, I was standing in the back of the audience watching the play ‘As You Like It’ that was performed not too far from the ... Read More »

The post What Shakespeare Can Teach Us About Enlightenment: All the world’s a stage appeared first on Enlightenment Podcast.

For many years, the fees charged by investment managers of mutual funds grew ever so slightly, gradually approaching 1.5%. Over the last few years, though, the growth in these management fees has stopped. In fact, it reversed. Last year the average management fee charged for actively managed mutual funds was 1.38%, or 138 basis points, where a basis point is one tenth of one percent. But that average is badly misleading. It’s misleading because it treats all funds, regardless of size, as the same. When you adjust the fees for the size of the funds, you find that the dollar-weighted average for actively managed funds is now below 100 basis points. Three things have caused this reversal in management fees: low returns in the stock market, the growth of exchange-traded funds (ETFs) and a price war among the biggest players in the market.

The first two of these factors need little explanation. Over the last ten years, an investment in many bond funds out-performed an investment in diversified equity funds. These low returns have many investors focusing on the costs they incur for the management of their money. These costs include transaction fees for trading securities and management fees for the companies managing mutual funds or exchanged-traded funds. The second factor, the growth of ETFs, is somewhat less obvious, but important. ETFs have garnered a significant share of new money invested in equity funds over the last few years. Companies managing ETFs charge low fees for managing these funds because they have very low costs for shareholder servicing and some other administrative functions associated with investment management. Shrewd mutual fund managers have reduced prices in order to manage the gap in pricing they allow for their managed mutual funds compared to comparable ETFs.

These two causes of the fall in prices for investment management now have a third important factor. This third factor may turn out to be the most important of all. (See the Symptom & Implication, “The industry is seeing its first price wars” on StrategyStreet.com.) As described in other blogs (see blogs HERE and HERE), Vanguard has started, and continued, a price war in the ETF market. For example, iShare’s MSCI Emerging Market’s ETF and Vanguard’s Emerging Market’s ETF compete directly. Vanguard’s fund charges 27 basis points. The iShare’s fund charges 69 basis points. The iShare’s fund entered the market well before the Vanguard fund, and was much larger than the Vanguard fund. However, during 2010, the Vanguard ETF added $18 billion to its fund while iShare’s added about $4 billion. Price matters among peers.

The iShare’s funds are not always market share losers, however. The iShare’s Gold Trust is an ETF that competes with a larger rival, SPDR Gold Trust. Until June of last year, both of these ETFs charged 40 basis points. In June, iShares cut its management fees to 25 basis points. SPDR Gold Trust stayed pat at 40 basis points. Over the next few months, the iShare’s fund gained $875 million in new money, while the SPDR Gold Trust saw a net loss of $1.2 billion of money under management. Price matters among peers.

These management fees can even go to zero. One ETF today has no management fee, zero. It gets its revenues by lending out the securities in its portfolio. (See the Symptom & Implication, “Technology improvements bring falling prices” on StrategyStreet.com.)

Of course, as companies engage in price wars, they advertise their lower prices extensively in order to capture as much market share as possible before their competitors respond. The result: customers are becoming ever more price sensitive about the management fees they pay, simply because the management companies tell them to be more sensitive.

How long will it be until this fee warfare spreads to other smaller types of ETFs? Not very long, as long as price moves share.

The United Autoworkers (UAW) is on a new campaign. The union plans to organize workers in hither-to non-union foreign-owned automobile plants in the United States. This campaign may or may not work, but in the long run it will prove futile unless the union can compete in the international market, against all international auto workers.

There are 575,000 autoworkers in the U.S. Nearly 20% work for foreign-owned plants. All of these plants are non-union. The foreign-owned plants were intentionally placed in right-to-work areas, many in the South.

The UAW is likely to have some difficulty succeeding with this campaign. The non-union workers already earn highly competitive wages and benefits. To date, these U.S. workers in plants owned by Toyota, Volkswagen, Hyundai and Honda have shown little interest in unionization.

Why would the union be so interested in this initiative? To preserve its membership. The traditional problem with unions is less the rate of wages they demand and more about the work rules they impose. These work rules reduce the productivity of the unionized plants. That has certainly been the case in the U.S. auto industry. As a result, the UAW is losing membership as UAW auto plants in the U.S. close under the onerous costs the UAW plants carry. If the union can succeed in unionizing the domestic foreign-owned auto plants to the same extent they have unionized the domestic manufacturers’ plants, they will be able to impose the same work rules and produce roughly the same productivity. The result should, in the union’s eyes, be a reduction in the rate of jobs lost in the union.

But there is a problem here. The UAW has already seen that it was unable to stop new non-union plants in the U.S. How will it stop future non-union domestic plants? O.K., let’s say they can do that. Will they also be able to stop all foreign non-union plants from becoming established and growing? Certainly not. Unless the union membership can compete on an international basis with competitive costs and productivity, this unionization effort is wasted money. If it succeeds, the U.S. loses more plants to plants located offshore. Union membership still falls.

It seems that one of the problems for unionized employees is one of definition. Union members often call their compatriots in competing companies “brothers and sisters.” These are certainly not brothers and sisters. In a marketplace they are competitors. Union employees have to be able to beat, or at least stalemate, these competitors or lose their jobs. This is true as long as the UAW can not control the entrance of other less expensive competitors, either in the U.S. or elsewhere.

The long history of the DRAM semiconductor market illustrates this. The U.S. manufacturers of DRAM semiconductors faced intense competition from the Japanese in the 1980s. The domestic industry succeeded in slowing the Japanese by using the International Trade Commission. Then arose new and equally troublesome problems. These problems were DRAM semiconductor facilities in Taiwan and Korea. Eventually, the U.S. industry evolved to the point where it had only one domestic producer of DRAM chips. Intel was one of the early competitors to get out of that market to focus its resources in the more complex, and much more profitable, domestic micro-processor business. SX4MBURBCAJQ

Hi Everyone, it's me, Grace. You might remember that a couple of years ago I earned my Canine Good Citizen award with my foster dad. Well, my mom said to me about a month ago, "Hey Grace, I know you already know this stuff, but what do you say you and I take the Canine Good Citizen test again?" So I told her I would do it again, just for her if it would make her feel good.


So we practiced all these things like sitting, staying, coming, not pulling on the leash, and passing by dogs nicely without staring at them. I didn't mind it at all, because she gave me lots of treats for doing it.




This past weekend I went with my family to this place with a ton of dogs. They called it a "dog show", but there was no TV there. Anyway, I had to wait for a long time and finally, I heard them call my me and my mom's names and we went into this fenced area. There was a lady with a blue shirt and she told my mom to have me do all these things. She kept saying "nice" after I did them.




After about 10 minutes of doing what she asked me to do, my mom looked very happy and gave me a delicious beef tendon and told me we had passed the Canine Good Citizen test. It was a great day.

I had the opportunity to play a preview edition of Quests & Cannons: The Risen Islands  from Short Hop Games in advance of the game’s upcoming Kickstarter campaign. Designed by Eric and Shannon Geller, the preview edition arrived in a bright and colorful cover box that hinted at the beautiful artwork within.

We got it on the table for a family game straightaway. As we unpacked the contents of the box, I was impressed with the quality of the wooden components. Especially for a preview copy, everything was incredibly well made and sturdy, which speaks to the care and enthusiasm Eric and Shannon have put into the game. The illustrations on the components are just lovely! The artists (Lily Yao Lu, Tony Carter, Regis Torres, Sita Duncan, and Lilia Sitailo) did a really great job integrating the theme into the materials. 

Quests & Cannons  is very easy to setup and the rules are straightforward,  so you can get started playing pretty quickly; no one is going to be stuck spending an hour reviewing the rules upfront. The only thing you really need to work out is whether you want to play the game solo, cooperatively, free for all, or in teams.  Regardless of the mode you choose, you’ll sit down as a leader of a kingdom, tasked with bringing prosperity (i.e. victory points) to your people as you explore new islands that have suddenly cropped up in the sea. The revelation of the islands has coincided with devastating famine and drought hitting the kingdoms to varying degrees, so you’re also on a quest to find a way to reverse these plagues.

And since prosperity can be gained through attacking other leaders during explorations, you’ll need to be thinking about battle defense and offense.  My kids are teens, so they handled the attacks pretty well, but your mileage may vary with your youngsters, depending on their age and temperament.

The underlying mechanics of the game are pretty simple:

• Explore to gather resources across the islands and turn those resources in to complete quests (pick up and deliver)
• Follow explicit instructions on map clue cards to do X action at X location
• Attack rival ships

Players can do three actions on a turn, choosing freely between move, gather resources, and attack. 

All of the how-to and particulars governing these actions are detailed in the rulebook (and in video play-throughs online). Variability in movement rules, attack/defense power, and resource storage capacity is dictated for each player by the leader card they’ve chosen at the beginning of the game (each one comes with special powers and differing stats) and the upgrades performed on their ship.

I did find a few issues with the mechanics for the Geller team to address before the final version is distributed:

• Explain in the rulebook what should be done if the map clue drawn cannot possibly be used
• Add a 0 space to the action point track on each player’s ship to track the exhaustion of the final action point
• Implement monsters or other descriptive elements with differing effects into the treacherous sea spaces to add more complexity

Outside of these issues, I recommend Quests & Cannons as a family game for gateway gamers (i.e. new to the hobby) or those who gravitate toward light strategy games. It’s kid-friendly and there isn’t any analysis paralysis inherent in the game.  It plays in under 90 minutes, gives kids exposure to different play modes within the same game, tackles conflict resolution, and comes with a variety of board layouts to keep things interesting over multiple plays. Note that this is not a game I’d recommend for players who prefer deeper strategy. Highly experienced gamers drawn to seafaring themes and beautiful artwork can find similar mechanisms with a bit more depth and complexity in other games such as Islebound (designed by Ryan Laukat from Red Raven Games).

Shiva Baby [US, Emma Seligman, 4] The ambient social pressures of a post-funeral gathering skyrocket for a directionless college student (Rachel Sennott) when attendees include not only the expected ex-girlfriend (Molly Gordon) but also the sex work client she’s caught feelings for. Knife-edge comedy of emotional suffocation uses a plucky suspense score for that extra frisson of social anxiety.

If you've been missing family events during the pandemic, this film is the cure for that. Polly Draper and Fred Melamed appear as the loving but insufferably intrusive parents.

Night of the Kings [Côte d'Ivoire/France , Philippe Lacôte, 4] When the red moon rises over MACA, the Ivory Coast’s toughest prison, its inmate boss appoints the new arrival as storyteller—a post that results in death if the tale ends before sundown. Prison drama with compelling narrative hook widens out to encompass ancient warfare, contemporary politics, and even a wizard duel.

Spring Blossom [France, Suzanne Lindon, 4] Bored with her classmates, an awkward 16 year old (played by the writer-director) pursues her attraction for a ruggedly handsome stage actor (Arnaud Valois.) Character drama sets aside the sexual aspect of this staple French cinema situation to focus on the emotion, periodically breaking from naturalism to have its characters express their feelings through dance.

This year’s Q&As are Zoom interviews between the programmers and filmmakers, which drop on YouTube when the films become available for online viewing. In the Q&A for this one we discover that the director wrote it when she was 15, a year younger than her character. She’s 20 now. Lindon is the daughter of well-known French actors Vincent Lindon and Sandrine Kiberlain.

Get the Hell Out [Taiwan, I-Fan Wang, 4] Taiwan’s notoriously pugilistic parliament tips into arterial spray when the effluent of a controversial chemical plant triggers a zombie epidemic. Zombie comedy features an eye-searing palette and an onslaught of optical overlays, and is paced like a quarter kilo of crushed Adderall. 

It’s quite an achievement to find the worst hue of every color on the visible spectrum. Fortunately the underlying message, that government officials would respond to a pandemic by idiotically making it worse, has no bearing on anything that comes to mind.

Last week I finished a new service written in Common Lisp. It now runs in production© every mornings, and it expands the set of services I offer to clients.

It’s the 4th service of this kind that I developed: - they are not big - but have to be done nonetheless, and the quicker the better (they each amount to 1k to 2k lines of Lisp code), - they are not part of a super advanced domain that requires Common Lisp superpowers - I am the one who benefits from CL during development, - I could have written them in Python - and conversely nothing prevented me from writing them in Common Lisp.

So here lies the goal of this post: illustrate that you don’t need to need a super difficult problem to use Common Lisp. This has been asked many times, directly to me or on social media :)

At the same time, I want to encourage you to write a little something about how you use Common Lisp in the real world. Sharing creates emulation. Do it! If you don’t have a blog you can simply write in a new GitHub repository or in a Gist and come share on /r/lisp. We don’t care. Thanks <3

We’ll briefly see what my scripts do, what libraries I use, how I deploy them, what I did along the way.

Needless to say that I dogfooded my CIEL (beta) meta-library and scripting tool for all those projects.

Scripts n°4 and 2 - shaping and sending data - when you can write Lisp on the side

My latest script needs to read data from a DB, format what’s necessary according to specifications, and send the result by SFTP.

In this case I read a DB that I own, created by a software that I develop and host. So I could have developed this script in the software itself, right? I could have, but I would have been tied to the main project’s versioning scheme, quirks, and deployment. I rather had to write this script on the side. And since it can be done on the side, it can be done in Common Lisp.

I have to extract products and their data (price, VAT...), aggregate the numbers for each day, write this to a file, according to a specification.

To read the DB, I used cl-dbi. I didn’t format the SQL with SxQL this time like in my web apps (where I use the Mito light ORM), but I wrote SQL directly. I’m spoiled by the Django ORM (which has its idiosyncrasies and shortcomings), so I double checked the different kinds of JOINs and all went well.

I had to group rows by some properties, so it was a great time to use serapeum:assort. I left you an example here: https://dev.to/vindarel/common-lisps-group-by-is-serapeumassort-32ma

Dates have to be handled in different formats. I used local-time of course, and I still greatly appreciate its lispy formatter syntax:

(defun date-yymmddhhnnss (&optional date stream)
  (local-time:format-timestring stream
                                (or date (local-time:now))
                                :format
                                '((:year 4)
                                  (:month 2)
                                  (:day 2)
                                  (:hour 2)
                                  (:min 2)
                                  (:sec 2)
                                  )))

the 2 in (:month 2) is to ensure the month is written with 2 digits.

Once the file is written, I have to send it to a SFTP server, with the client’s codes.

I wrote a profile class to encapsulate the client’s data as well as some functions to read the credentials from either environment variables, the file system, or a lisp variable. I had a top-level profile object for ease of testing, but I made sure that my functions formatting or sending data required a profile parameter.

(defun send-stock (profile &key date) ...)
(defun write-stock (profile filename) ...)

Still nothing surprising, but it’s tempting to only use global parameters for a one-off script. Except the program grows and you pay the mess later.

SFTP

To send the result through SFTP, I had to make a choice. The SFTP command line doesn’t make it possible to give a password as argument (or via an environment variable, etc). So I use lftp (in Debian repositories) that allows to do that. In the end, we format a command like this:

lftp sftp://user:****@host  -e "CD I/; put local-file.name; bye"

You can format the command string and run it with uiop:run-program: no problem, but I took the opportunity to release another utility:

• https://github.com/vindarel/lftp-wrapper

First, you create a profile object. This one-liner reads the credentials from a lispy file:

(defvar profile (make-profile-from-plist (uiop:read-file-form "CREDS.lisp-expr"))

then you define the commands you’ll want to run:

(defvar command (put :cd "I/" :local-filename "data.csv"))
;; #<PUT cd: "I/", filename: "data.csv" {1007153883}>

and finally you call the run method on a profile and a command. Tada.

Deploying

Build a binary the classic way (it’s all on the Cookbook), send it to your server, run it.

(during a testing phase I have deployed “as a script”, from sources, which is a bit quicker to pull changes and try again on the server)

Set up a CRON job.

No Python virtual env to activate in the CRON environment...

Add command line arguments the easy way or with the library of your choice (I like Clingon).

Script n°2 and simple FTP

My script #2 at the time was similar and simpler. I extract the same products but only take their quantities, and I assemble lines like

EXTRACTION STOCK DU 11/04/2008
....978202019116600010000001387
....978270730656200040000000991

For this service, we have to send the file to a simple FTP server.

We have a pure Lisp library for FTP (and not SFTP) which works very well, cl-ftp.

It’s a typical example of an old library that didn’t receive any update in years and so that looks abandoned, that has seldom documentation but whose usage is easy to infer, and that does its job as requested.

For example we do this to send a file:

(ftp:with-ftp-connection (conn :hostname hostname
                                   :username username
                                   :password password
                                   :passive-ftp-p t)
      (ftp:store-file conn local-filename filename))

I left you notes about cl-ftp and my SFTP wrapper here:

• https://dev.to/vindarel/ftp-and-sftp-clients-for-common-lisp-1c3b

Scripts n°3 and n°1 - specialized web apps

A recent web app that I’m testing with a couple clients extends an existing stock management system.

This one also was done in order to avoid a Python monolith. I still needed additions in the Python main software, but this little app can be independent and grow on its own. The app maintains its state and communicates it with a REST API.

 

It gives a web interface to their clients (so my clients’ clients, but not all of them, only the institutional) so that they can:

• search for products
• add them in shopping carts
• validate the cart, which sends the data to the main software and notifies the owner, who will work on them.

The peculiarities of this app are that:

• there is no user login, we use unique URLs with UUIDs in the form: http://command.client.com/admin-E9DFOO82-R2D2-007/list?id=1
• I need a bit of file persistence but I didn’t want the rigidity of a database so I am using the clache library. Here also, not a great activity, but it works©. I persist lists and hash-tables. Now that the needs grow and the original scope doesn’t cut it any more, I wonder how long I’ll survive without a DB. Only for its short SQL queries VS lisp code to filter data.

I deploy a self-contained binary: code + html templates in the same binary (+ the implementation, the web server, the debugger...), with Systemd.

I wrote more on how to ship a standalone binary with templates and static assets with Djula templates here:

• https://lisp-journey.gitlab.io/blog/lisp-for-the-web-build-standalone-binaries-foreign-libraries-templates-static-assets/

I can connect to the running app with a Swank server to check and set parameters, which is super helpful and harmless.

It is possible to reload the whole app from within itself and I did it with no hiccups for a couple years, but it isn’t necessary the most reliable, easiest to set up and fastest method. You can do it, but nobody forces you to do this because you are running CL in production. You can use the industry’s boring and best practices too. Common Lisp doesn’t inforce a “big ball of mud” approach. Develop locally, use Git, use a CI, deploy a binary...

Every thing that I learned I documented it along the way in the Cookbook ;)

Another app that I’ll mention but about which I also wrote earlier is my first web app. This one is open-source. It still runs :)

 

In this project I had my friend and colleague contribute five lines of Lisp code to add a theme switcher in the backend that would help him do the frontend. He had never written a line of Lisp before. Of course, he did so by looking at my existing code to learn the existing functions at hand, and he could do it because the project was easy to install and run.

(defun get-template(template &optional (theme *theme*))
  "Loads template from the base templates directory or from the given theme templates directory if it exists."
  (if (and (str:non-blank-string-p theme)
           (probe-file (asdf:system-relative-pathname "abstock" (str:concat "src/templates/themes/" theme "/" template))))
      ;; then
      (str:concat "themes/" theme "/" template)
      ;; else :D
      template))

He had to annotate the if branches :] This passed the code review.

Lasting words

The 5th script/app is already on the way, and the next ones are awaiting that I open their .docx specification files. This one was a bit harder but the Lisp side was done sucessfully with the efficient collaboration of another freelance lisper (Kevin to not name him).

All those tasks (read a DB, transform data...) are very mundane.

They are everywhere. They don’t always need supercharged web framework or integrations.

You have plenty of opportunities to make yourself a favor, and use Common Lisp in the wild. Not counting the super-advanced domains where Lisp excels at ;)

• Common Lisp course in videos – it helps me, and you ;) I added 9 videos about CLOS last month, and more are coming. It’s 86 minutes of an efficient code-first approach, out of 7+ hours of total content in the course. After this chapter you know enough to read the sources of the Hunchentoot web server or of the Kandria game.

I have done some preliminary Common Lisp exploration prior to this course but had a lot of questions regarding practical use and development workflows. This course was amazing for this! I learned a lot of useful techniques for actually writing the code in Emacs, as well as conversational explanations of concepts that had previously confused me in text-heavy resources. Please keep up the good work and continue with this line of topics, it is well worth the price! [Preston, October of 2024]
