    I bought the Dell Latitude 11 5175 Win10 tablet because of its excellent specs for the price, but it has the weirdest problem.

    I had the tablet configured to connect to the Logitech M557 bluetooth mouse and the Microsoft Foldable Bluetooth Keyboard. When the tablet connects to a Wi-Fi hotspot generated by my Nexus 6P smartphone, it loses its bluetooth mouse and keyboard connections. The mouse and keyboard continue to appear on the bluetooth devices list as “Connected”, but no input registers. Repeated attempts to remove the device and connect it again will eventually result in a complete inability to connect the device to the two bluetooth devices. Only a system factory reset on the tablet will restore the ability.

    Just turning off the wi-fi hotspot, or disconnecting from the hotspot, does not restore the bluetooth connection. I need to turn the hotspot off, and restart the tablet. Then the devices work fine.

    Connecting the tablet to a wi-fi signal originating from a normal wireless router does not trigger this response. I observed it only on the Nexus 6P (Project Fi plan) and a T-Mobile hotspot device on a Project Fi SIM. Didn’t get to test it out with AT&T or other CDMA providers.

    I googled the Dell tablet with “bluetooth interference” to find this article, but in it it only indicates that 2.4Ghz signals, the standard Wifi spectrum, are also used by by bluetooth devices. Why is it only occurring with hotspots? Maybe the source of signal is too close to the tablet?

    I have used a variety of Surface line tablets and iPad pro, and don’t recall this problem in the past. Although, using the tablet over a hotspot connection WHILE using bluetooth peripherals is not something I purposefully tested on every device. (Never imagined that there could be a problem on that front).

    This is a bug that severely limits the utility of this tablet as a laptop.. I’m conflicted because a Surface Pro with 256GB will sell at $1,000$1,300. The Dell, although refurbished, was only $413. Also, I am not entirely positive that this problem did not exist on Surface products. I will try out USB tetheringt, and if that method does not cause problems, stick with that.

      Okay! I changed the Wi-Fi hotspot settings from 2.4Ghz to 5Ghz and now the BT device is not losing connection! Hooray!

    A brief intro to: Mordor, the Depths of Dejenol

    Watch this video on YouTube.

    Mordor: Depths of Dejenol is one game I had almost forgotten that I played it. But it’s likely that some nightmares when dreaming probably derived from the experience of falling into a pit to a deeper level on Mordor.

    I can’t even pinpoint the years I played this game. The game was released in 1995, but I was playing the demo version of what seemed like a pre-1.0 version. It just feels like I played this game after Baldur’s Gate, which was around 1998-99. I can’t remember who introduced me to the game – it was probably Sungwoo(sp?) . I recall the person introducing me to the game, and me spending months trying to minmax the race and class characteristics based on specific higher level spell and weapon requirements, and just starting to pick up intro level teleportation type spells, then visited Sungwoo and saw him playing with very advanced characters, flying over pits, etc. Which was a pretty standard experience on every game he introduced me to. I actually don’t recall Sungwoo’s correct name – the older brother’s name started with S, younger started with J. I must have spent at least one year on this game. Did dad play it? Did brother?

    The game’s help file extensively documented every aspect of the game, very much like wiki sites of these days. I think the scariest description of something that could go wrong was teleporting your party into a wall (rock tile). The thought of your body meshed into a wall, instantly dead, unable to see anything, was terrifying. This description was in the helpfile for lower level playthrough because it was part of the Morgue resurrection service – the resurrection service said “if you just died, it’s not that expensive. If you died by teleeporting into a wall, chances of success are low and also more expensive”

    I’m surprised I could remember the name of the game. I could recall it was “Mordor something”, so after some googling was able to find references to the game. Probably easier to remember given the other mordor in middle earth.

    The most incredible of all this is that the game is still selling for $15 – it ships a boxed set. And the binaries are still Windows 3.1 binaries – the updated demo file shows the developer did some touches in 2012 so that it can install up to Windows XP (although it’s unclear whether the actual game works on XP)

    Hmm so this was actually an earlier DnD experience than Baldur’s Gate, although Mordor is more of a hack & slash..

    Working on the @civiCRM Service Inquiry Form https://krcla.ourpowerbase.net/service2 and finding this dilemma:

    Going from the multi-column form https://krcla.ourpowerbase.net/en/k/service to a flat structure, the service categorization came out cumbersome so instead I tried a two-pronged approach:

    • have them first select the big categories of IRP/HAP/Housing, and then show a second list that goes into depth. (useful)
    • detect key words from the client describing their problem in the paragraph box, and auto categorize. since conditional “set to” creates unchangeable variables, create a checkbox to deactivate feature. (very nice)

    The problem is that the two methods each work, but canj’t be in place simultaneously. The second list method relies on the IRP sublist, HAP sublist being hidden and making them shown depending on which larger category was chosen. Because these lists are hidden, I can’t make the keyword detection both show the sublist and make selection from the sublist at the same time. If I just tell it to choose an item from the sublist, the sublist shows up (as per sublist conditional, not the keyword detection conditional), but no choice is made.

    Which feature to kill, which feature to kill…

    When four screens comes in handy

     
  • 10:57 am on May 24, 2017 Permalink | Reply  

    I dreamt that we were having a press conference to announce the Know Your Rights android app. It was someone tall and big (Karn? Staff 1) and.. Staff 2 ? doing the conference, I was sitting in the audience side. The dream started when the conference ended, and Staff 2 was about to say “Thank you for coming..”.

    So I quickly went to Staff 2 and told them that they hadn’t done the live phone demonstration yet. “Oh ok”. “We will show you how to install and use the app”.

    While this was happening, another staff, Staff 3, had already connected to Chromecast and for some reason was stuck trying to find the app among four superhero posters on the TV screen.. like the Incredible Four or something. Staff 3 I think was white.. they were like “where is it? It’s supposed to be around here..” So I went to the staff and said “Let me connect my phone, we can make this quicker” but Staff 3 started screaming “no, I can do it! This is when I need to practice”

    I could feel the reporters wanted to leave, since they were mostly done anyways. Then I realized that this was not June 3rd, the date for which (insde the dream at least) the conference was scheduled for – it was May 23rd.. or 30th? So I started thinking “what happened? Was this a press conf on something else and Staff 1 figured this was the time to announce the app?” That’s how the dream ended.

    I guess it highlights the importance of coordinating time information properly.
