How to fix a Lenovo Thinkpad Compact/Slim keyboard plastic

Fri, 30 Jan 2026 21:58:57 +0100

I have two Lenovo Thinkpad Compact/Slim keyboards. One if them is USB and the other is Bluetooth. I really really like them because they have almost the same keyboard as my x230. But what I like most is the trackpoint/thinkpoint. Avoiding mouse usage is great. Also more space in the table :).

BUT… in both of them my trackpoint was broken. I noticed that it was due to a very small black plastic that was broken.

Here in the comments we find some interesting info by the user seaboatsk:

Ms. Keiko Matsui, one of the three memembers of the band, is now teaching at a college in Japan. She has been in USA for some years and has been awarded for her excellence by a US smooth jazz committee in 2000 and 2001. In Japan in 80s, so many TV and radio programs put songs of smooth jazz bands, such as, Cosmos, Casiopea (Japanese), Fruitcake (Dutch), Mezzoforte (Icelandic), and Shakatak (UK), on air.

Removing JavaScript 3: Not adding it for YouTube

Mon, 09 Jun 2025 21:52:31 +0200

Still alive.

Today: Removing YouTube embedding. I saw something cool in the AAMSX web, so I decided to copy that. The idea was to use Lite YouTube, however… I got many errors regarding the CSP (Content Security Policy), as it is set to null and it was, again, including JavaScript. So fuck it.

So instead I did this Hugo shortcode:

{{- $videoId := trim (.Get 0) " " -}}

<youtube-thumb videoid="{{ $videoId }}">
    <a href="https://www.youtube.com/watch?v={{ $videoId }}" target="_blank"><img
        src="https://i.ytimg.com/vi/{{ $videoId }}/hqdefault.jpg" alt="YouTube
        Link" style="border: #FFFFFF 4px double;"></a>
<p><center><small>Click to watch in YouTube (New tab)</small></center></p>
</youtube-thumb>

And if you put this in layouts/shortcodes/youtube-thumb.html, you’ll be able to use it as {{< youtube-thumb VIDEO_ID >}} and you’ll get the video thumbnail in JPG and be able to click on it to watch it. The target="_blank" makes it to open a new tab. I kind of like it. It’s less functional compared to lite youtube, but it works and it does not add JavaScript on our side.

Fixing a Catit Pixie Smart Feeder that bumps and gets stuck constantly

Thu, 28 Nov 2024 20:37:39 +0100

One of my two smart feeders (the newest) was bumping and having problems putting the feed to my cats. After a lot of time, I went up online and found a Reddit post that had very valuable information.

Some users had good luck removing the rubber bands from the spinning part of the feeder, but the user Set-Condition-5 wrote the following:

Team, while removing the rubber guards helped, it turned out our jamming
problem was caused by the screw that connects the white main gear you see when
you remove the top housing ( the half with the food) to the motor being
completely loose. If you remove the small white cap on the gear you can access
the screw and tighten. This stops the gear from raising up which was causing our
jamming.

This screw is this one (click on the image to get a color one ;)):

I follow the YouTube Channel Music Radar Clan which is an excellent channel where the creator does small documentaries on a variety of topics related to music and musicians. If you understand Spanish, I highly recommend it.

In his video on Citypop he showed how this genre was the portrait of a growing economy and positivism that Japan lived in the 80s. Consumerism was everywhere, all was good as there was money and things to do with it. It was a golden age for the people living there apparently.

Hello! I’m still alive.

Just 2 years after our first edition of kicking out javascript here we are again, reducing the size and processing time of the website.

Yes, it was pretty light but we can go FURTHER! Also we want this to be viewable by obsolete browsers, of course. New things are not always progress when we can simplify.

The only javascript that I had at this moment was the highlight.min.js, a javascript code in charge of handling code highlights. Some time ago I discovered that Hugo has now included Chroma for syntax highlighting. This is done in compile time and colored with just a CSS file, so… I was up to try it.

Modifying a Sony Hitbit 10P to use a standard barrel jack power supply

Sun, 13 Mar 2022 07:37:39 +0100

Greetings everyone!

A couple of weeks ago I got a Sony HitBit 10p from a mechanical keyboard enthusiast from the University, a great guy :). He know where to leave MSX things. There was a particular issue: There was no power supply. After changing one power supply for a Sony HB-T7 I thought that it would not be much of a problem. And actually it was not!

I found a tutorial in spanish on how to do this with a phone charger. As you can see in the video, what he does is to use a soldering point below the switch connector to solder a 5v input.

Pyspark and UDF types problem

Mon, 02 Nov 2020 12:20:05 +0100

Hello!

Here is a fast note that might not be obvious. Beware with UDF types in PySpark.

from pyspark.sql.functions import udf
from pyspark.sql.types import IntegerType, FloatType


def very_fun(idk):
    return(22)
    
def floating_fun(idk):
    return(22.0)

df = sqlContext.createDataFrame(
    [
        (1, 'foo'), 
        (2, 'bar'),
    ],
    ['id', 'txt'] 
)
    
funfun_int = udf(very_fun, IntegerType())
funfun_float = udf(very_fun, FloatType())
    
floatingfun_int = udf(floating_fun, IntegerType())
floatingfun_float = udf(floating_fun, FloatType())

df = df.withColumn('funfun_int', funfun_int(df['id']))
df = df.withColumn('funfun_float', funfun_float(df['id']))

df = df.withColumn('floatingfun_int', floatingfun_int(df['id']))
df = df.withColumn('floatingfun_float', floatingfun_float(df['id']))

df.show()

And the result is not very amusing:

Get the most out of MSXHub

Sat, 12 Oct 2019 14:48:22 +0200

In this post I’ll introduce MSXHub and how to use it in a very “linuxy” way just by organizing our packages a bit. You’ll need an MSX with MSX-DOS (probably in a flashcart) along with a network card and your fingers.

Introduction to MSXHub

MSXHub is a superb repository tool for our MSX Systems that allows us to download MSX software (tools, games…) directly from our MSX without needing a computer. We just need a UNAPI compatible network card and a flashcart to run the software over MSX-DOS.

By default weechat doesn’t support multiline messages, but you can have that using the multiline.pl. In order to install it just run weechat and write /script. There you’ll see a lot of nice scripts to customize weechat. Write multiline and press return to filter the plugins by that keyword. Then just select it if it’s not selected already and then write i then return. Then you’ll have multiline enabled :).

CLI Recommendations

I will introduce a bit the applications and where to start without much detail, because there’s a lot of documentation already available :).

Well, here are my two cents for the first point, BitlBee. BitlBee is a service that acts as a gateway for several instant messaging services, e.g. Facebook Messenger, Google Hangouts or Slack. Ok, but… a gateway to what? IRC, of course.

SparkR gapply mess

Fri, 12 May 2017 08:56:31 +0000

Hello,

Do not assume anything. Never. Ever. Specially with SparkR (Apache Spark 2.1.0).

When using the gapply function, maybe you want to return the key to mark the results in a function as follows:

countRows <- function(key, values) {
    df <- data.frame(key=key, nvalues=nrow(values))
    return(df)
}   

count <- gapplyCollect(data, "keyAttribute", countRows)

countRows <- function(key, values) {
    df <- data.frame(key=key, nvalues=nrow(values))
    return(df)
}   
count <- gapplyCollect(data, "keyAttribute", countRows)

SURPRISE. You can’t.

You should get this error:

Error in match.names(clabs, names(xi)): names do not match previous names

Well, that’s weird. Why is this happening?

Sony HitBit 55/75P dead VRAM diagnosis

Sat, 25 Feb 2017 10:48:47 +0000

Hey!

Recently I bought a broken 75P just for fun (and well, it was cheap :)). It had a video problem which, after reading a couple of msx.org posts (Hit-bit With Broken Graphics and 75P black screen mainly), I believed it was a problem of VRAM as Grauw pointed.

That was a clever way to debug it. Watching how Basic characters are output, you can see which bit is broken in the ASCII chart. Why can you point to which bank is failing if a bit fails?

asMSX bugfix 1: Ifs on .megarom

Sat, 03 Sep 2016 12:49:45 +0000

Hello!

Finally some improvements on asMSX. At the start of this project JamQue told me that he had issues using ifs when the “.megarom” clause is active. The issue correction can be seen here in Github.

The problem was that when generating a byte (for example, an LD instruction) it checks if it is able to generate it if the condition established for this level allows it.

Original:

guardar_byte(b)
{
if ((!conditional_level)||(conditional[conditional_level]))
if (type!=MEGAROM)
{
 ...some code...
}
if (type==MEGAROM)
{
 ...some code...
}

The first if will only affect the if(type!=MEGAROM) as it doesn’t provide brackets to define a block, therefore it will get only the next sentence. Also instead of doing if(type==MEGAROM) I just did an else.

Learning Bison and Flex: The calculator

Sat, 20 Aug 2016 18:28:25 +0000

Hello everynyan,

I’m learning how Bison and Flex work with an O’Reilly book and there can be found an example on how to build a calculator (which has an error on the code, probably there are more in the book, that’s why it has that kind of critics, but it works.).

I ended up making an extension on it just to test my forgotten grammar skills. The code is the following:

Understanding asMSX Volume 2: lex.l

Fri, 19 Aug 2016 23:27:42 +0000

Welcome back to the mystery machine!

Today, the spooky lex.l. As we saw in the previous post this file is full with constants, but to be more precise this is the file where you tell how to treat every string found. In fact, constants are not defined in this file but in dura.y,

For example:

“ld return MNEMO_LD”: Whenever you find a string that’s which characters ld, treat is as a token with value MNEMO_LD (Mnemotechnic for Load instruction).
“0x[0-9a-f]+ yylval.val=(int)strtol(yytext,NULL,16);return NUMERO;”: Whenever you find 0x followed by 1 or more characters from the set {0-9a-f} (hence, hex), transform them to a long int (as strol can treat hex values directly) and then to an int and set it to the yylvval, which is the flex’s return value, and return that this token is a number.

So as you have seen, at least in this case, Flex is the one that is in charge of understanding the meaning of each token as defined in this file.

Tue, 16 Aug 2016 23:00:08 +0000

Hello!

Welcome to another trip into another dark cave. Today we meet asMSX, an assembler for MSX’s Z80 made by Pitpan and bought and released with GPL license by cjv99 (Thanks!).

Motivation

It’s known that this assembler has some bugs, e.g. skipping IFDEFs when using MegaROM so there is an interest on knowing the internals of the code in order to fix this kind of bugs. My goal is not directly fixing bugs of this code but to provide more information about the code so all the people from the community may get themselves the code and fix it if there are any new bugs.

On R and parallelism

Thu, 24 Mar 2016 01:20:01 +0000

R, that language that is has gained its momentum due to the people discovering the need of analyzing data. There are other several alternatives but this is my poison (or poisson!) of choice. In this post we will try to cover how to parallelize your R code with the package parallel.

Why bother?

One of my main concerns when I was starting with R is that WOW! Everything runs in one thread!. I was amazed by the fact that the language was still being used with that issue inside. How fool I was! Parallelism is doable in R. But, why must we bother about it? If we were still living in the era where we only had one core inside the CPU it won’t be an issue, but some smart guys thought that there was an issue when trying to set higher frequencies to the CPUs (power consumption mainly) and they decided to put more CPUs in a chip instead of going to a single faster core. That has been our paradigm for a couple of years and it appears to be working, right?

Well…

Hello. What is expected of the first post of a blog? Well, actually it’s not the first post as this blog was created by $ADMIN for me to put my webcomic on it and I had 3 posts with test for automatic music play in loop (vital for my comics). But I was lazy. Very lazy.

¯_(ツ)_/¯

Whatever. Welcome to the captain’s log on the spaceship to amazing knowledge and Nutella.
