In the registry, oen HKEY_CURRENT_USERControl PanelKeyoard.The entry InitialKeyoardIndicators can have the following values:0 NumLock is turned OFF after the logon.1 Disale NumLock.2 Numlock is turned ON after the logon.EDITIf I understand your dilemma correctly, you like one NumLock setting and your oss likes another. So why don't you create another user account for your oss? You can also use a screen-saver with your assword, to force him to logon in order to use the comuter. I elieve that's a etter solution than monkeying with the registry.Regarding the registry key, there are actually two of those. Here's how it works:After oot and efore login, Windows reads
HKEY_USERS.DEFAULTControl PanelKeyoardInitialKeyoardIndicatorsand sets it u as default. After Logon, Windows Alies the setting fromHKEY_CURRENT_USERControl PanelKeyoardInitialKeyoardIndicators (0Off, 2On).
This setting is stored indeendently inside each user rofile, and the state from the Windows Session is saved at logoff. This means if you turn your NumLock on, a value of 2 is written at logoff, and NumLock will e toggled on at next login.
Can myetherwallet e hacked from the rowser extension?If you have given a rowser extension ermission to do so, it can access all data on all ages you use, including MyEtherWallet. You're lacing trust in the rowser extension.You can increase your security y only accessing MyEtherWallet on a rowser without extensions, for examle Chrome's incognito mode.
The only way to e 100% certain of your security is to generate your rivate keys with dice rolls (or another hysical method that you know to e random). Only enter the rivate keys on a comuter without network connection and without wireless networking caailities (e.g. WiFi, Bluetooth, NFC, infrared). Also make sure no other eole or cameras are watching your screen, keyoard or dice. Also, make sure no microhones are listening to your tying atterns, ecause on most keyoards every key has a slightly different sound. (you can roaly hear it)If you're not doing all that, you're lacing trust in the manufacturer of your hardware, your oerating system, your rowser, rowser extensions, the software you use to generate rivate keys and other software running on your comuter.It's a matter of comromising etween security, trust and convenience.------
Not debouncing on a MIDI keyboard
I guess the 1us RC lowpass filtering tries to keep off false keyhits caused by phones and other radio transmitters. The debouncing is performed with software. Do not add slowness to the circuit which detects if a key is pressed. Players hate delays. There's enough it already (MIDI transmission,communication between the MIDI interface and the computer application, sound generating DSP, sound system DSP, distance to the loudspeaker). As much as 20ms total in circuits ( the distance to the loudspeaker) is well achievable by bad design and it makes a MIDI keyboard painful experience for a competent player.Make your system to react as soon as possible to a keypress. Leave debouncing delay for the key scanning software and let it affect only to the time when the releasing of the key is taken into the account. Playing a sound a little too long is much less annoying than a delayed start. A simple debouncing strategy in software is to scan the keys say in every 3 millisecond if the caused 0.
..3 ms extra delay is not a problem. The maximum value 3 ms is equivalent with about 1 meter extra distance to the speaker which can be acceptable------

Get bluetooth keyboard working identically to built-in keyboard
Troubleshooting is a process of elimination and often requires patience.As a starting point, I'd try to reset both the macOS Bluetooth Device List and Bluetooth Controller. IMPORTANT: This will reset all connected Bluetooth devices, including any wireless keyboard or mouse, so they will need to be reconnected.
Before commencing, you will need to have the Bluetooth icon showing in the menu bar. If it is not there, open System Preferences > Bluetooth and enable the option Show Bluetooth in Menu Bar.Resetting the macOS Bluetooth Device List and Bluetooth ControllerFollow these steps:After doing the above, test your keyboard for a while to determine if it's now working better.
If it's not, there are other things we can try/test for on the MBP side of things. However, before doing that, the next step should be confirming the keyboard itself is okay. If possible, test the keyboard with another computer and confirm it's working okay with that. If it isn't, then replace your keyboard batteries of make sure they're fully charged and test again.Let me know how you go up to this point and if necessary we'll proceed further------
Learning piano via MIDI keyboard questions
Question 1) I use an 88 key Roland stage piano with midi out when I need it. Stage because it saves space and fairly portable (still 25kg) and have sometimes packed it away in flight case when not being used. Still requires a dedicated space in any room.
Question 2) I got fully weighted because its main purpose was to learn how to play classical piano, but as user15664 says in his post there are different purposes. Also see this previous post: How to gain velocity feelQuestion 3) A good brand piano will feel and sound good. You can listen to demo's yourself on-line but you will probably have to rely on reviews of the hammer action for the feel (since you are new to it)In your original statement, you said you wanted to toy with music production. Majority of cases for which it will be better to use good software pianos. The whole skillet is different and not as necessary to have fully weighted keys (i.e. arranging and tweaking velocities and notes as oppose to flawless playing in a recorded take)And finally, I would reccomend second hand as Digital Pianos depreciate in value like cars.------
What features are cursor controlled on the A380 Navigation Display?
As far as I know the whole FMC (or as it is called in an airbus: MCDU) is controlled by this cursors. So you don't have the limited options by just using scratchpad and line select keys, but you can graphically interact with the items on the screen by using the cursor.A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight management of the flight plan. Using various sensors (such as GPS and INS often backed up by radio navigation) to determine the aircraft's position, the FMS can guide the aircraft along the flight plan. From the cockpit, the FMS is normally controlled through a Control Display Unit (CDU) which incorporates a small screen and keyboard or touchscreen. The FMS sends the flight plan for display to the Electronic Flight Instrument System (EFIS), Navigation Display (ND), or Multifunction Display (MFD).Wikipedia - Flight Management System------
How to test which button is stuck
In the first instance, maybe give the keyboard a damn good blow with a can of compressed air, in case there is debris under the keys. Biscuits are GREAT for screwing up keyboards.Failing that, I would give Dell technical support a call and explain your problem as it is still under warranty. It would save you some time if you ran through the diagnostics (F12 on boot up and then select the diagnostic option) before calling. It might save them getting you to do it while on the phone.(sorry if this does not apply to you-) Over here in the UK, if you tell them that you're comfortable changing the keyboard and ask nicely, they will just send the part and let you do it yourself. Not sure whether this will work in your neck of the woods but worth a go nevertheless, nothing to lose right?Trying to fix it yourself might end in a completely broken key. If you are lucky enough to remove the key without snapping the plastic, the scissor mechanism is a pain the backside to put back together again------
How to change keyboard layout by USB dongle?
There are several parts to this question.1) Can you make some kind of hardware that permutes keys from an USB keyboard as if it were a customized Dvorak keyboard?Yes, you can. You can use any embedded computer that has both an USB host and a USB client port. However, you will have to write the software for that yourself: It's very unlikely that ready-made software for that exists. The software will have to translate HID events from the physical keyboards to the HID events corresponding to the Dvorak layout, but that is not very difficult.2) Will you be allowed with your own private keyboard or your own piece of hardware that you can put between an existing USB keyboard and a PC in a high security place?If the people who are responsible for security are not completely stupid, they will allow no extra hardware at all - no keyboards you carry with you, no commercial "dongles", no custom self-made "dongles". And you'll get on the watch list for even asking.
So if you are asking because you need a Dvorak layout in such a place, this is not a viable solution------
How windows boots up in hibernate mode using keyboard?
The Wikipedia article was imprecise, and I already fixed that. It's true that hibernation ends up with exactly the same device power state as when regular shutdown is applied. But while that state is called a "shut down", in modern computers some basic electronic modules still function. It's the motherboard that decides what to do, once it gets in that state - according to it's construction and features designed by manufacturer.These features are eg. powering up by WakeOnLAN, keyboard shortcut, mouse move or time-preset launch. Or even pressing the front power button, which is not a real circuit breaker like in "the old times", but just an electronic, low-power "sensor" that, when pressed, allows that inner electronic module to know you want to power the rest of modules on.
To completely shut the computer (motherboard) down, you still have to completely unplug it's power sources or, in case of some desktop PC-s, use the power switch on the PSU.Mind though, that RAM is truly powered down when in hibernation state. It's content gets stored on the hard drive right before shutdown and then gets recovered when you start computer again.
