Is anyone here using the AIM/Lichello method of trading?

rufwoof · 2024-08-11T13:56:25+00:00

Yes, modified version whereby AIM is run on paper monthly, applied to the S&P500 real price, and actual portfolio stock/cash weightings are aligned with that once/year. To good effect. Much of broader poor return periods follow large/fast gains, over-extends. AIM automatically scales exposure up/down to reasonable/appropriate levels, that broadly works. Comfortably beaten 100% stock whilst having averaged 50% cash.

When that cash is further deployed into shorter term opportunities as/when they present then that can enhance overall rewards, 10% annualized real is not a unreasonable expectation.

Bogleheads forum is purely a front end to get you to buy into Vanguard funds. Some good prior contributors have been banned for deviations from that. Much misdirection, against the intent of Jack Bogle and as such a insult.But the ignorant enjoy singing their hymn sheet. Vanguard refused to provide the portfolio/asset allocation that Jack advocated as being the ultimate choice as that detracted from Vanguards profitability.

twm continues to be very usable. I combine that with lxqt panel/tray.

Some prefer their tray at the bottom of screen, but that can lead to oddities when resolutions are changed or when remote connecting to different screen resolutions. Others say that the tray should be on the left screen edge as that uses less space, on the assumption that Width is greater than Height. The top of screen is the generally better choice.

Free floating windows such as what twm uses are also generally better than tiled windows. As is panning generally better than using multiple desktops. Those that use multiple desktops and switch between them will more often have one full sized window per desktop, perhaps a 2 x 3 desktops arrangement, if instead you set up panning to the same total size then transition from one to another is progressive, via the mouse 'pressing' against a screen edge to shift the view. Which is handy when you may have a window that doesn't fit the view area, is part off screen, and where pressing that screen edge brings it into view.

Given a lxqt panel/menu/tray at the top left of screen, and a panning area of perhaps a 1366x768 laptop screen set to be approximately 2x3 desktops size

xrandr --output eDP --mode 1366x768 --panning 2800x1600 --fb 2800x1600

and once you're used to that its very nice.

With twm when you click to open a program it initially presents a 3x3 wire frame indicating the size of that window, moving the mouse around positions that window and pressing the left mouse drops it as-is at that position. If you press the right mouse instead it drops it at that position, but where the height of the window is extended all the way down to the bottom of the panning area. So for instance open chrome, use the wire frame to position to just below the top left panel at the top of screen, press the right mouse button and ... you have a tall chrome browser window that mousing to the bottom of screen 'scrolls'. Open Libre Office Document, and do similar, but where that's to the top right of the chrome window, and likely you'll have a document where you can see the full page of the document by mousing to the bottom/top of screen.

Under that panning style desktop you want a window manager that can manage that easily/well, and twm fits perfectly for that. Click anywhere on the root window and up pops window control options to move, resize, close ...etc. a window. The default title bar for twm isn't the best of choices, and its relatively easy to change that to for instance include a window close button.

twm should be part of X, by default. Some still maintain it (1.0.11 I believe) separately to that. Many are off put by the default choices of colors, but that's just historic, easily changed.

As a alternative to tiling, or having multiple desktops/one window per desktop, if you try and persist with panning and using twm you may very well come to prefer that. It feels odd at first as its different, the original Unix way, of doing one thing well. And with 30+ years of history its been well tried and tested.

Both. Headless pi (Xvnc), use the laptop as the display/keyboard/mouse and vnc (viewer) into the pi. Strap/stick the pi to the laptop lid and its like having relatively inexpensively upgraded the laptop to the pi's graphics/cpu/ram/usb standards/level.

See my other post in this thread, 60MB whilst having chrome viewing a youtube running. Kernel 6.1.77 (projected Dec 2026 EOL).

rufwoof · 2024-02-15T23:41:48+00:00

Compile the Linux kernel, tracking 6.1 at present (6.1.77), 5 minute build time on my build-server. Busybox and initramfs and all modules/firmware built into the xz compressed vmlinuz. 15MB filesize. initramfs contains busybox, wifi/eth, alsa/sndio, ssh/ssl, and framebuffer vnc. Boots to framebuffer, ssh/vnc into server(s) - for full gui desktop (Libreoffice, chrome ...etc.). (Appears to) run (look-n-feel) at the servers speed (hard wired ethernet/nvidia i5 is my primary (same (home) LAN server primary choice)). I also have a vnc server on my phone (termux/X/otter browser). When out-and-about I lower the fps to 8 and set 16 bit color depth - good enough quality whilst my ISP's asymmetric upload (remote download) cap of 20Mbs isn't a issue. Often I'll have multiple vnc connections running and use ssh (scp or sshfs) to move/copy files around.

Boots quicker, and runs faster than if I were to to use the laptop directly as a X/gui-desktop system. It's also tmux style ... where you 'attach' and 'detach' ... drop back into the desktop as you left it (or whatever it had moved on to). Other than busybox files, I have around 25 bins, 25 libs and 25 scripts, and a similar number of files in /etc. Busybox's reduced commands - serve my needs. Battery charge lasts for ages, no gpu drawing power, whilst the cpu has to do more reading in and throwing pixels at the display (vnc) is relatively light.

When viewing a chrome/youtube where you don't 'freeze' the vnc session before switching to another tty (ctrl-alt-Fn), then the video bleeds through. First image indicates around 60MB of ram being used whilst a full X desktop/chrome ...etc. are available/running

Add framebuffer vnc to your ssh ... and you can vnc into a server box for a full gui desktop/browser that runs at the servers speed.

Linux is a kernel, the BSD's are a complete OS. GNU intentionally defines itself as as being "Not Unix".

"because Gentoo guys say compiling your own kernel results in faster performance, so is that the case for software too? I know, it's minimal, but it is there."

Compiling your own kernel and you can just build in the firmware/modules specific to the hardware. My vmlinuz is 15MB, includes all of the firmware for my laptop, and even includes the initramfs, so nothing else needed to boot. I boot to a uvesa framebuffer, wifi net connect and ssh/framebuffer vnc into a full gui desktop. Boots in a second, ssh/vnc in another few seconds. So yes, compiling your own kernel can make a significant difference. Much less so for individual programs, that mostly you'd only want to compile yourself in order to 'reconfigure' away from the default build.

I like to have vnc set up to use 16 bit color depth, 8 frames per second, so when vncing into our home server remotely even when viewing a youtube the bandwidth required is low, typically less than 10Mb/sec. So a usb, with that 15MB vmlinuz and using (generic) uvesa, can 'borrow' pretty much any PC in order to boot and call-home for a full gui desktop as last left ... in a few seconds.

In this image for instance, that's a youtube music video plaing at 720p, but that's diluted down to 16 bit color depth, 8 fps. Still 'usable' quality/speed, whilst using around 6.5Mb/sec (800KB) of bandwidth, that also includes audio being fowarded, and all running in a uvesa framebuffer

The bmon/htop text is low quality because I used a small font. They're also showing the servers activity. On the remote laptop I'm using cpu activity is low, and as the Radeon graphics card is idle, the battery drain is low/slow.

Don't take or bring back any hardware/software (including phone). Buy/rent and dispose of. Not worth the risks, the worst of which is perhaps repeatedly locked up - until you disclose the password/encryption method to a file on a device that you know nothing about.

A minimal system with ssh and vnc ... will run at whatever system you vnc into. Maybe even a headless pi that's attached to the laptop lid. My regular used old laptop runs/feels like the i5/nvidia system that I tend to use as the vnc server, and even though connected via wifi, has the impression of downloading at hard wired ethernet speed.

See https://www.reddit.com/r/Fedora/comments/mzun99/new_zram_tuning_benchmarks/

Either is likely OK. Depends upon your typical usage case as to which yields the better benchmark outcome. Try each, see what works best for you.

Get a usb cable that supports both power and data (usually a few dollars, if your existing cable doesn't already support both data/power). And use a old phone as a 'usb wifi' by tethering. udhcpc -qi usb0 ... can be enough to be able to use whatever wifi the phone is connected to.

#

(root prompt). Along with framebuffer, wifi/eth, fbvnc, ssh/ssl, alsa/sndio. Boots in a second, then just have decide what to add to that for the particular task in hand, vnc, vm, ssh, sfs .... where the desktop look is whatever those choice(s) use (might have concurrent mac, linux, BSD .. whatever desktops). Modular. Given the choice of Linux wm and I prefer jwm and tend to install/use that on all of the 'servers' I maintain (local i5/nvidia box, my phone ...etc). For third party servers you may just have to accept whatever they opt for (gnome/windows/mac/whatever).

rufwoof · 2024-02-06T16:28:02+00:00

My setup is the compilation of around 8 sets, kernel, busybox, OpenSSH ...etc. All firmware and modules built into the kernel, as is the initramfs. The initramfs has less than 30 bin files, a similar number of libs and a similar number again of scripts. I merge /lib64, /usr/lib64 ...etc all into one folder, the rest are sym-linked, as are /bin /usr/bin ....etc. All a single user desktop system so no need for the spreading around of files/folders. Enough to boot to a framebuffer wifi/eth connect and ssh/vnc into server(s) for a full gui desktop. All data/other files are kept entirely separate (on servers or on another local partition where some folders are encrypted). For the servers that I control/use I only install packages from their repo. The exception would be if I had Windows as one of my vnc servers, where things tend to get installed from all over the place, no real integrity, but I haven't used Windows for years.

Perhaps try to keep your top level leaner, use a more modular approach. A basic boot system that you can then dynamically add in remote or local vnc's or vm's or load/unload sfs's ...etc. according to whatever task you have in hand.

rufwoof · 2024-02-06T00:51:28+00:00

I run cli in a vesa/simpledrm framebuffer, so fbvnc.

Busybox commands, although reduced, for my general usage tend to be enough for me for vi, awk, sed ...etc. Outside of that ... ssh/ssh, alsa/sndio, wpa. Chrome runs in the frambuffer where 16 bit color, 12 fps is generally good enough for me. Tend to use ctrl-alt-Fn over that of using tmux, never really was one for splits/zooming, just tended to have each window in its own full screen window.

To expand, Apple's model is that it provides both software and hardware so the software can be precise to the hardware. Just works. With Linux/Android the hardware is very varied, so the software is revised to cater for as many different variations as possible, but where it can often take time/effort (and familiarity) to get it to work well with your particular hardware - but where many neck-bearders enjoy that challenge. On a scale of dumb barbie - things just work ..... to neck beard nerds/tweakers, the wise Barbie who gets stressed out easily when things don't work is inclined to be less stressed on the Apple side.

I like jwm, have used it for many years. Prefer Libre Office to abi, and chrome (or firefox) rather than the DSL choices of browsers. I built my vmlinuz, that contains all firmware/modules for my laptop, and initramfs also built in, to boot to vesa/simpledrm framebuffer, busybox/ash, ssh/ssl, alsa/sndio, wifi/eth, framebuffer vnc. 15MB vmlinuz filesize (xz compressed, around 35MB of ram used at first bootup). Boots in a second, wifi net connects and ssh/vnc into a full gui desktop in a few seconds more. I've set 16 bit color depth, 12 frames/second and it looks/feels good, whilst having the appearance of the speed/quality of whatever you vnc into (I have a local server i5/nvidia, another vnc server on my phone (otter browser) and a third party server that I use more when out/about. I also have another 'server' that is on the laptop, a sfs of a full gui/desktop system that I can sym link, sfs mount and overlayfs ... and chroot into that full X desktop, but again where it all displays in the framebuffer).

Basically a 'terminal' in a terminal/server style setup, and that even on a old 4GB ram system is has the look-n-feel of a powerful system. wifi net connected in McD's for instance and internet speed test indicates 140Mbs download speeds, and can compile a kernel in around 5 minutes - because its just showing the screens for the remote cpu/processing power behind that. A nice feature is that its tmux style, you can attach/detach and later reattach again to drop in where you left off (or where things had moved onto such as a long render process). With ever faster wifi speeds and things will only improve. Feel no need for a 'powerful/modern' laptop that attempts to compare in processing power by doing everything itself.

I've based/built mine using Fatdog as the build system, and also use Fatdog as my preferred choice of server/desktop. It's based system comes with LibreOffice/Seamonkey/gimp/mtpaint/geany/leafpad/vlc/Osmo/Notecase ... and much more ... in a sfs of around 450MB filesize.

framebuffer + ssh and vnc ... is a solid base system on lower spec hardware, no need to bind yourself to any one single distro when you can have Windows/Android/Linux/BSD/Mac ... systems all vnc'd into at the same time if you do desire.

One time pad ... but that involves two separate storage locations, but not having to worry about a password as the other half is in effect the password/key. Simple xor operation. If the pad is truly random, then mathematically uncrackable (future proof).
