  1. Re:And yet still can't tell TAB from Ctrl-I ... :- on Vim 8.0 Released! (google.com) · · Score: 1

    I use IJKL for character movement along with Ctrl IJKL for screen movement which means I can't use Tab and Shift-Tab for insert a literal TAB (say for Makefile) and/or indent / unindent . The work-around is to use the slightly awkward Shift to indent/indent and and Ctrl-Q Tab to insert a literal tab respectively.

    I see. I don't mind the arrow keys, however I use pg up/dwn, home/end in combination with Ctrl. Ctrl+left/right yields a word progression as opposed to character progression. So I press Ctrl for large movements and arrows for character movements. I think there are a few more I use unconsciously as well that don't come to mind immediately.

    I'm very fussy about keyboard customization and optimization of minimal keystrokes

    I very with you on this. I think it's important because it is the limiter on the throughput you have to your machine, fatigue and injury using a computer, in my experiences.

    I don't remember when it happened, however the left or right click terminology for mousing stuck when users were trying to understand how to use a computer en masse, however it doesn't translate to the left side of the body. For context, consider using a right handed mouse. The right hand index finger is on the left button called 'select' and right button is called 'context' or 'menu'. The middle button is called 'middle' and introduced paste, then later scroll wheel and left/right. Now consider the same thing with a left handed mouse, left and right click no longer makes any sense.

    I realised this when I first helped left handed users get set up ergonomically. Later injury forced me from being a right hander to left for some time and I got to experience their frustrations. I ended up ambidextrous (and a pretty good drummer), so I use two mouses to satisfy the ergonomics I have requirements to avoid re-injury.

    I don't know if that is formally defined somewhere or I've unconsciously picked it up along the way, however to communicate it specifically during training sessions, I started referring to them as 'select' as index finger click, middle as middle finger click and 'context' as outside finger click, so that it makes sense to left handers as well.

    The reason I told you all that is..

    This works but I find it clunky.

    If I may offer a suggestion, you may find some favourable vim functionality by using it with cygwin/X term, it's (DEC VT100) vs (ansi) terminal type. So when manipulating text an index click positions the cursor, a double index selects a word or a begins a drag to select, and a triple click selects a line (as normal). However you add the middle click and that becomes your first paste buffer, which is also a visible buffer.

    Find the right terminal type (like xterm under linux) and vim will support the scroll wheel to page text, the mouse to position the cursor which *might* help the issue you are facing .

    -- which is the main reason I love Vim's modal style.

    When you add text in the edit mode of vim then select an add or insert at a certain position you can continue to select and paste text into the edit point by only using index and middle clicks. It is a simple, but powerful facility that I use in combination with command mode. For example apply the same regular expression over a range on some things over a number of files by middle click and y/n, :'a,'b g/expression/ s/find/replaced/gc :wn

    I _would_ use Ctrl-# for bookmarks, and Buffer Management, along with other macros I use daily.

    Interesting. I tried Ctrl-#, but I'm not sure how it should work? Would you mind sharing what I am missing?

    I don't know your preferred hotkeys and shortcuts so I can't say. Probably not.

    I use bookmarks, however I think I might be using vim differently. First I use "m" (for mark) and then a upper

    Class A uses the most power (~20% efficient), Class AB about 60% and D comes in a little under 100% (~90%) or so because the semiconductors are acting as switches dissipating very little heat. The downside is that the high frequency switching can induce all manner of interference which will cause havoc if not properly dealt with.

    You are right. I was confusing a class D amp construction with an amplifier type that has only a single power amp transistor on the output phase - thanks for pointing that out.

  3. Re:No no no. on Ask Slashdot: How Do You Build Your Own Vacuum Tubes? · · Score: 1

    Actually that's not true, just ask a guitarist (and IAAG - I Am A Guitarist!)

    Vacuum tubes create a noisy signal, but in a weird coincidence, they do it in a way that is pleasing to the ear. The clipping and distortion sounds "warm," and there's an added depth in the sound (harmonics) that you don't get via transistors....So, sir, you might argue that you dislike what a noisy tube does to your signal, but you can't say some people won't perceive it as improved, as it's about personal taste.

    IAAP and Vacuum amps add a 'third harmonic distortion' to an input signal. Whilst this is desirable for a guitarist, for home listening it introduces distortion that I did not intend to be there when I produced your excellent performance. All that time I spent adjusting the attack and release on the compression to capture those really cool movements of your fingers on the strings are lost because a 'audiophile' decided that they knew better that the people who produced the music in the first place.

    Transistor based amplifiers also introduce distortion. Referred to as THD (Total Harmonic Distortion) I like to think of it as 'temporal' distortion. It occurrs when the push and pull sets of the amp cross the waveform (sine) over 0v. It takes about .6v to activaste the transistor and this translates to a 'jag' at 0v of the waveform. It is unlikely that you are ever going to hear it - however that is what semi-conductors are all about, getting more accurate. I think the new class D amps eliminate even this issue, however they use more electricity.

    You're right - to some extent it is a matter of personal preference. However home stereo valve amps reduces the "accuracy" of what was intended to be presented to you, the listener and to some extent being an audioophile is an oxymoron. If you like the 3rd harmonic distortion then that is ok, however many audiophiles like to claim this is an 'accurate' representation of a playback, when in fact it is distortion.

    Now pick a valve amp for an instrument, then that is different because the valves and electronics are being vibrated by the amplification of yor playing - it sounds cool. You don't get that same effect from a semiconductor guitar amp. My friend and I like to mess around with these amps and do things like changing the transformers to give the amp a more 'ballsy' sound. We took a Musicman 130W valve amp and used Australian sourced transformers as the iron used in them is denser (I'm told) which seems to make the sound more meaty - so it is not just about the valves in the amp.

    For my next trick a valve amped Theramin - at least for the pre-amp stage :)

    Back in the 90s I was obsessed with WTC as a place I wanted to visit and possibly work at.

IIRC one floor was engineered to take the weight of 1-2 of the floors above before it would pancake. It was also designed to take the impact of a fully fuelled 707, so I don't know how that compares to a 767.

    The only thing I didn't see in those specs was that one building would fall because another tower did, that does not make a lot of sense. Perhaps a forensic investigation would have had a civil engineer available to answer those questions for us.

    It is useful functionality.

    Getting rid of the analog port obsoletes all analog headphones released, ever. Drag.

    You also have to keep in mind that you want to be able to have a private wired connection to the phone. That is not just useful, but essential to the function of a communication device like a phone, a hard-wired connection.

    But - allowing an outboard wired DAC is a Good Thing.

    Yep.

    Right now, several popular phone models have DAC and analog output stages that are excellent but the presentation is completely marred by replay gain and digital volume control, among other processing.

    If Apple puts a big fat "ZERO SUM" option somewhere in iOS that forces software out to be forwarded to the jack unimpeded, I would be completely on board.

    Well, this will be a huge vector for DRM control of audio experience. Get ready for more advertising.

  21. Let us be a bit pragmatic about this by analysing the electronics and the data stream.

    I'm a fan of the jack because it allows me to choose the headphones. The only thing I don't have control over is the DAC in the phone.

    For general listening Beats are a heavy headphone and after seeing a construction breakdown on /. some time ago found their specs to be average. A good set of senheiser headphones would be a better investment. Bose look and sound good however I had a hard time tracking down specs last time I was shopping. I'm pretty fussy and my headphones have a response range 16Hz - 28kHz and handle 200mw of power. I have to wear them alot for mixing so they have to be leightweight and they also have interesting features like auto muting when I take them off. I found AKGs to be perfect here.

    Apple's decision means I can choose higher quality DACs for headphones however it also means the end of the era for lightweight quality headphones as it means these devices will have to carry a battery, receiver, DAC, amplifier *AND* audio membrane. More likely, significantly more functionality.

    Considering iTunes accepts music at 96Khz for the masters it is likely this is the next phase of innovation Apple is suggesting where DAC converter in headphone technology improve as consumer grade headphones are able to process higher bitrates with better sound quality and still deliver an enjoyable power delivery and battery life. What it means for people like me is that my high quality gear exposes the limitations of the phone.

    It also means all the associated DAC technology on the phone only has to match the bandwidth of the phone's speakers. I can see why this is a plus for manufacturers as I doubt the DAC in many phones now could deliver the dynamic range that my AKGs can handle and the only way to improve that is to have better DACs and amplifiers on the phone. By not having to have that shootout with other phone manufacturers all manufacturers reduce cost, complexity and, power consumption of their phones.

    However it also means the end of private analogue connection to the phone as locally eavesdroping on unencrypted bluetooth connections becomes more probable.

    This is a new type of market, that apple is creating because now they race is to produce phone headphones that are hyped or actually can deliver quality audio to consumers at a rate more frequent than the delivery of a new phone. Neither bad or good, but a change to the market for headphones.

    The laws justified after 9/11 were the very ones that enabled the type of police state monitoring of citizens that not just US, but many other countries like the UK, Canada, Australia and, others all endure today. Before 9/11 western governments had not passed laws to remove our freedoms (that terrorists hated) because adequate laws were already in place to deal with terrprism. Those laws were based on what was learned by the UK government dealing with the IRA's terrorism.
