AI so far

Writing this to see how it has aged in a few years.

I held back on using AI for a few years, especially running it on the cloud (meaning a datacenter which is wasting good water). Played around a bit with local models on an Nvidia 3080 but the results were meh.

In the end, I decided to go and experiment a bit more with it while it lasts.

Pretty sure that in a few years the AI as we know it now will go the way of the dodo, just not certain how. But if we look at the past, the giants of yesteryear are in quite a few cases the dodo’s of today (CompuServe anyone) or they pivot into another reality completely (Nokia anyone? ).

Maybe in a few years there will be no more AI, or perhaps only local-run AI’s. Perhaps on a small chip card. Who knows.

I decided on using Claude for a year, and I have to admit, it impressed me. Creating a program in python + flet, wiring schemata’s…. it can do it all.

My conclusion for Claude: as long as you know your stuff and get detailed enough, you can get it to create ‘stuff’ for you that would take ages for you otherwise. Just don’t be afraid to say that it must stop focusing on the wrong bit, and tell it to look at other alternatives. That also helps you save your credits.

At the same time, it scared me how easily I would think of ‘Ask Claude’ for trivial stuff, so I try to stay away from it for things I can go and search for myself (and even there the first response you get is usually from AI).

We’ll see how it goes.

55 today

Another year goes by, and as someone said, you are past half-time now… or if framed differently, you have survived 55 years already – plenty of other people don’t get that old.

Anyway, with my meager blender skills (still improving!) I managed to make this, still pretty happy about it that this at least I can already manage ! Perhaps a better 56 next year 🙂

Happy 55th birthday to everyone who also has his or hers anniversary this year !

Wordfence is the max

I’ve been a happy user of Wordfence on all my WordPress blogs for years now, and I just realised that, while I did do a lot of word-of-mouth promotion for them to other blog people and clients, I never did publicly state how much safer I feel installing their default (free!) Wordfence firewall solution.

So this little blog post just to say that the Wordfence people are absolute good guys, letting people install a free solution, and providing even more improvements if you go for the paying solutions as a few clients have done over the year.

Thanks Wordfence !

Twitter dying ?

I’ve been following the first week of Elon Musk taking over Twitter and all the changes he has implemented, including, apparently, firing half the workforce.

Moving to Mastodon is a solution, but then again, it’s totally different from Twitter (at least the last time I looked at it). Will have to look again soon.

I’m certain that there are other twitter clones out there being born as we speak…

Anyway. I’ve kept this blog up and running, with Twitter possibly going the way of the dodo, and Medium promoting paid content, it might be relevant to keep this blog around and start updating it again.

Curious to see what changes Elon will bring to Twitter next week.

Roborock 2.4Ghz Wifi issues and some solutions

Roborock S6 Pure vacuum cleaner and it's charging station.

I just bought a Roborock S6 Pure vacuum robot. Having 2 cats and plenty of hair every day lying around we needed something that could do a quick clean every day.

While I’m vary happy with it’s performance, there is a WIFI connection issue that has been plaguing all Roborock S5 and S6 vacuum robots.

The Problem

The problem I encountered was that it was not that hard to get the Roborock S6 connected to the WIFI.

Just make sure that your WIFI password does not have any weird characters in them (symbols) as apparently your vacuum cleaners’ wifi programming can’t handle that.

However, once it was connected, I couldn’t really control it from my phone – it worked, but only infrequently. If I was further away, on the other side of the house, then it worked, maps got loaded. But only sometimes, with frequent timeouts and slow internet errors. Weird, but it got me thinking…

As officially stated in the manual, Roborock does not support the 5Ghz Wifi spectrum. And nowadays that is becoming more and more standard in routers. Most routers still support both though, sometimes separately, sometimes transparant for the user. Some of the new ones only support 5Ghz, although for your own comfort, you are better off with one that supports both.

At home I have got a router that supports both, and automatically chooses how to connect to a device depending on the throughput – I have the same network name for both radio networks, so my phone only sees the one network name, but depending on distance it’ll be the 2.4Ghz or the 5Ghz network (the higher the frequency, the faster the connection, but the harder it is to penetrate walls with the signal; so the further away you are, the better it is to use 2.4Ghz).

And that caused the problems : when I was farther away from the robot and the router, I got notifications; I could access the amp, etc… because my phone automatically used the 2.4Ghz radio network. But when I wanted to change settings I automatically went close to the Roborock. And closer to the router, so the phone switched again to the better 5Ghz connection. All without me knowing it. And normally that’s not a problem. However, when you are communicating with a 2.4Ghz device, that IS a problem…

Solutions

Here are some solutions to your problems :

  • First, check that your WIFI password does not contain any strange symbols.
  • Set your encryption scheme from WEP to WPA. Honestly, if you are still running WEP, you’re asking for troubles. WPA or WPA/2 is better protection as WEP nowadays is eminently hackable.
  • If you only have a 5Ghz network router : you’re out of luck. You can still use your Roborock, but without the smartphone interface. But…
    Do check in your router that your router perhaps DOES have 2.4Ghz, but it is turned off. For that you will need to access the router’s administrative interface, which is different for each type of router and how it has been setup… Time to start searching for that router installation manual ! If it is turned off, turn it on, and then setup that network and connect your Roborock to it.
  • You have a router that supports both frequencies, and both are active but using different network names : eg. “RadioGagoo24Ghz” and “RadioGagaa5Ghz” – make certain to use the 2.4Ghz network name and *not* the 5Ghz.
    Additionally, the device you are controlling may need to use 2.4Ghz network as well. I’ve read reports from people that did not manage to control their Roborock using their recent iPhones, but did manage to do that with an (older) Android phone (one which probably only has a 2.4Ghz radio).
  • For those dual router, you could, if you want to, disable the 5Ghz network and force everyone to use the old network. But you are losing out on high-speed downloads, and some devices nowadays like USB network antenna’s (for plugging into pc’s without a wifi card) only support 5Ghz…
  • You have a router that supports both frequencies and meshes them into one network name (which is what I have) – and you want to keep on using that solution for whatever reason : what worked for me was to enable the 2.4Ghz GUEST network (and only that one) and link the Roborock to that. I also allowed devices on that network to connect to my network.
    Afterwards I set my mobile phone back to my regular network, but I can still control the Roborock ! This works because
    a) the Roborock now has a dedicated 2.4Ghz network and can save information like maps. And because it can talk to my internal network,
    b) my phone can see it and communicate with it.

I hope you manage to get your Roborock working. And honestly, Xiaomi, if you are reading this, an upgrade on your next model to 5ghz is something that you really need to consider. The problems selling this to European and/or American customers will only get bigger staying on just the 2.4Ghz network.

Installing HDX Media engine on Mac

This is a post to quickly detail a solution to the problem of installing the Citrix HDX media engine plugin for the Citrix Workspace app on your Mac.

If it keeps insisting that No, your workspace app is not installed while it IS installed (because, you know, you are actually using it!) then the problem might be that the script inside the installation package is not executed.

Why is it not executed ? Because the script is stored with a typo that only shows up on a case-sensitive file-system. And most Mac files systems are NOT case-sensitive.

Here’s how to fix it :

~ pkgutil --expand /Volumes/HDXRealTimeMediaEngine/Install\ HDXRealTimeMediaEngine.pkg Install\ HDXRealTimeMediaEngine.pkg                                                 
~ mv Install\ HDXRealTimeMediaEngine.pkg/Scripts/RTMEconfig Install\ HDXRealTimeMediaEngine.pkg/Scripts/RTMEConfig             
~ pkgutil --flatten Install\ HDXRealTimeMediaEngine.pkg Downloads/Install\ HDXRealTimeMediaEngine_custom.pkg  
~ open Downloads/Install\ HDXRealTimeMediaEngine_custom.pkg

Basically, it unzips the .pkg file (similar to .zip) , unzipping it, renaming a file in there by using the unix mv (move) command so that the script will run correctly, and then zipping it up again under another name.

Running that custom package (in the script above it’s saved in Downloads) will normally allow you to get this to work.

I found this in an online bulletin board from the HDX version 3 versions back. Apparently it’s still not fixed.

Using the Fritz!Wlan 1160 repeater to increase my wifi range [review]

Why I need a repeater and perhaps you as well

Recently with the hot weather we wanted to sit in our garden, but nowadays we take a tablet with us instead of a book.

Unfortunately the telenet router is all the way on the other side of the house, so the range is about nil and zilch once you go 2 meter further than our backdoor. So I needed a repeater, which is basically an extension for your wifi and is normally totally transparant to your tablet or laptop or smartphone.

In detail: your router talks to the wifi repeater (via wifi, no develo in sight here!) and the repeater is just a client on the network.
The repeater broadcasts the exact same wifi access name as your router (hence the name of the thing), and as it is closer to the devices that want to connect to the wifi, those devices use the more powerful radio of the repeater. Invisible to them, the repeater relays all those requests back to the router.

This is of course not optimal for speed but at least a slower connectivity is better than no connectivity. And it really depends on where you put the repeaters (yes, you can install multiple ones that connect to each other!). One caveat is that they need to be somewhere close enough to the router so that there still is a reasonable connection, but far enough that your devices farther away can still reach them.

So I recently purchased the Fritz!WLAN Repeater 1160, which I read some good comments about on tweakers and can be had for about 70 euros or slightly less.

It’s a stylish flat box with some red on it and some symbols so it is not the most un-noticable item in your room. If you can tuck it away in some powersocket nobody is using but still have good wifi connectivity, the better. On the box it says “Gigabit Wifi” but that all depends on how you configure it and how far away it is from the router (see above for more detail).

The front is actually quite well thought out.

You have a WLAN symbol, with below it the WPS button and under that status lights for power, WLAN and info.

The WLAN symbol lights up bars according to how strong the connection is to the router. In my case, I get about 3 bars, which is very good.
As such it gives you a rough estimation of how good the repeater can reach the router.

SETUP

Setup was so easy that I was actually doubtful that I done it :
1) plug it in somewhere close to the router
2) press the WPS button on your router
3) press the WPS button for 5 seconds on the repeater
4) done !

Connections can be either on 2.4Ghz or 5Ghz, or a combination of both, where you receive 2.4 and send on the 5 Ghz. This can help with the throughput speed, if you set it up right.

You can configure it manually if you don’t have a router with WPS, but for me WPS worked immediately. I actually reset it to factory settings just so I could try the other way as well. There are actually only 3 actions you can do with the device without going into the config screen :
– press the WPS button for 1s to turn the WIFI on or off
– hold the WPS button for more than 5 seconds : start the WPS handshake sequence
– hold the WPS button for more than 15 seconds : reset to factory settings

There was one problem that I had : once connected via wps to the router, I could not connect to the local fritz.repeater admin page that is described in the manual for further configuration. The only way I could access it was right after resetting it to factory settings. Once connected to the router the page was no longer accessible.

Performance

Surprinsingly good performance, and very stable. Both in seamlessly connecting to it and in the throughput to the router.
Absolutely no problem to watch youtube on the tablet all the way in the back of the garden !

So I heartily recommend this device if you want to extend your wifi for a low price !

G-Sync setup not showing in your menu ? Colors on your Dell S2716DG not right ?

I just bought this sweet, sweet new DELL monitor : the S2716DG monitor with G-Sync. This monitor has a TN panel that’s very good and can run at 144hz in G-Sync mode with selected nvidia cards like my GTX970.

G-Sync mode allows your card and your monitor to synchronize display refresh rates to the GPU in your GeForce GTX-powered PC, eliminating screen tearing and minimizing display stutter and input lag. The result in a game is no tear or blurry images, just buttery smooth gaming experience with crisp detail. I’ve tried Battlefield 1 before and after G-Sync and the experience is incredible.

One thing that bothered me was that when I initially searched on how to enable G-Sync, I could not find the menu entry in the nvdia control panel. I reinstalled all drivers and did a clean install of them just to be certain, but nothing changed. No “Set up G-SYNC” menu option. This really vexed me.

The solution seems to be a simple one, too simple really : just take out the displayport cable out of your screen or graphics card (you did use the dp cable to connect your screen, right?), then wait a moment, and plug it back in. After a second of hesitation, the “Set up G-Sync” menu option suddenly appears in the nvidia control panel. Problem solved !

The build of the screen itself is great, with small bezels, and can easely be lifted or lowered to the correct setting, as well as tilted or turned. The foot it connects to is solid and has a quick-release button.

But the default factory settings make the screen somewhat bright and harder to read than it should be. And the menu panel of the monitor doesn’t allow you to change the gamma settings, however with the nvidia control panel you can set it up correctly.

I found some settings on Reddit that I tried and quite liked. They are here for my own recall and perhaps your help should you want to try them out :

Nvidia Control Panel>Adjust desktop color settings:

  • Brightness-50% SAME
  • Contrast-50% SAME
  • Gamma-0.75% DIFFERENT
  • Digital vibrance-60% DIFFERENT
  • Hue-0 SAME

Click APPLY to save the settings.

DELL Monitor settings:

  • Brightness-30% DIFFERENT
  • Contrast-75% SAME
  • Color > Custom Color: R-97% G-99% B-96%

This definitely made the screen colors more vibrant and noticeable. The screen is a bit pricey, but not as much as the others, and the results are very good.

So true. How we get older…

“We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly.
We grow partially.
We are relative.
We are mature in one realm, childish in another.

The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations.”
 ― Anaïs Nin
