Laptops for Linux!
ASL includes the Accelerated X-Server, while LinuxLaptops runs the standard XFree86. According to Xi Graphics, there is usually a 40% to 60% performance improvement gained from running the commercial servers, as well as support for many more cards. I have not noticed any visible advantage; GNOME/Enlightenment is slow on both laptops. Nevertheless, if you do graphics-intensive work, there may be a benefit here. Both laptops use the ATI 3D Pro LT card, so the graphics performance is similar. Neither in X nor in console mode did I notice the lagging, slow updates associated with LCD screens of the past. Graphics on both are superb.
Well stocked, fully loaded
KDE or GNOME
Faster X server
Complete, functional laptop for Linux
Clear, flicker-free 14.1" LCD monitor
Console mode is ghosty
Disk access a bit slow
Has some unnecessary software
The window manager situation is a bit different. The AS-LT300 offers a choice between KDE and GNOME, and the Attache uses GNOME/Enlightenment. While the Attache's devotion to GNOME/Enlightenment (which is well configured) keeps good faith with the open-software movement, the window manager and desktop environment are a tad too resource-intensive for a mid-range laptop, not to mention being unstable and slightly buggy.
As is typical of Linux, audio support is a mess. The Attache awaits the release of the free sound driver, so other than beeps (which you can mercifully turn off with a volume control), you don't have audio support. The AS-LT300 has OSS audio support, which means you can play CDs, but the audio devices are not set up properly so you'll miss out on mpegs and the like (I expect ASL has fixed by now). Still, the microphone appears to be working, because at full volume, the machine starts generating horrible feedback when I type. What to do about MIDI? Might as well get a hardware sequencer.
Network support on both laptops is fine and simple. All you have to do is plug an Ethernet/Modem card into the PCMCIA slot, edit the network files (five minutes tops), reboot, and your system will be completely on-line. Networking is transparent and I even swapped the network card in and out of the computers while running and without any disastrous effects. The network card gets very hot, though; I worry it will melt. It would be preferable to have Ethernet/modem built into the laptop instead of using a PCMCIA card, since it looks less graceful to have this gizmo sticking out of the laptop's side.
Benchmarks are good general indicators of system performance, but they're often misleading and not entirely relevant. It is true these laptops do not compare well performance-wise to desktop machines or servers, especially in terms of disk access, but then, these laptops are not servers and servers are not particularly portable. Laptops are generally one- or two-user machines and will not be called on to do anything resource-intensive. As for disk access, you don't need a super fast drive if you won't have several dozen users reading and writing all at once, and you don't need too many megahertz or that much RAM to run vi or Emacs. Multimedia would be the one area for which a single user would need supercomputing power, but then multimedia support on Linux is not outstanding. So, Table 2 shows the Bonnie and BYTEmark results. The AS-LT300 shipped with a faster processor (and higher price tag) so its processor results are slightly better, while LinuxLaptops has spent much effort tuning for hard-drive performance, hence the better results here. I set both laptops to “Suspend to RAM” and “Large Filesystem”, and ran the benchmarks several times for best results. Bonnie's results fell into a broad range, due partially to variance in access speed depending on the location of the data on the disk. Laptop drives tend to be single speed, so the farther in you go, the slower your access speed.

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
