I didn’t get into networking professionally until 1996. It was at a certain bank that is full of Americans in a hurry. Anyways, as part of the line of interrogation from some outside consultant he pulls out a vampire and does the old man rant of ‘I bet this kid doesn’t even know what this is!’ bit.
Except I did.
Although to be honest, I’d never seen one in person, but I’d read about them in some ancient book about Unix Networking that went over in great details how to put down the cable, how to pay attention to the black bands in the cable, as they are the only place you should be tapping, how to use the tapping kit, and how to secure the vampire to the cable, along with the appropriate AUI cable to the host (PC).
So yeah, I did get the job. The old guy was genuinely shocked.
When the best friend becomes an enemy, and the main villain becomes you yourself and blood flows like a river, someone will definitely have to answer the main question – Who is behind the awakening of ancient evil and is there still a chance for humanity?
I saw this ‘gem’ pop up on steam for $3.50 HKD (so $0.50 USD?) and thought what the hell let’s try it out. SharpShooter3D is well, a DooM mod of sorts, but it also feels a lot like Duke3D with the inclusion of vehicles and ‘moving room/vehicles’ like train cars. At it’s heart is GZDoom 3.3.2 which states in the license:
Parts of the voxel code in the software renderer use code from the BUILD engine by Ken Silverman and are used under the terms of the GPL v3 with permission.
Well isn’t that cool! The best of Duke3D and Doom! All in one.
It captures the imagined feel of the eastern block, old factories, nuclear power plants, lots of guys in trainers & Adidas all over the place, along with copious alcohol and milk (yes milk is the health thing here!).
Not to mention the punk sound track is pretty good for such a seemingly ‘low end offer’. Had this come out 20 years ago, it really would have set the world on fire, and probably set off quite the few controversy, but today it’s a discount mod that no doubt the devs did put a bit of work into.
I have no idea if the game is 90% off for the rest of the world, but I’d say it’s worth a look at the price.
(this is a guest post by Antoni Sawicki aka Tenox)
This is a lame duck, low effort post. And if you already know it it’s obvious. However this question seem to be asked a lot on the intertubes. I hope it will help someone else, as there is no good readily available answer out there.
Problem: I wanted to have SNMP on my Comcast/Xfinity router so I can monitor current bandwidth usage.
Possible to enable on vanilla router? – Nope
Do 3rd party, Comcast compatible routers do? – Nope
Can you SSH or hack in to the router to do it? – Nope
Can you load custom / hacked firmware to do it? – Nope*
Nope or very hard / unsupported.
So is it possible at all? Yes, but with a separate device. Comcast/Xfinity routers have so called “Bridge Mode” which essentially turns them in to a DOCSIS modem without router / firewall / wifi access point.
Solution: Turn on Bridge Mode in your vanilla Comcast router and buy a WRT firmware router / access point. I got Linksys AC3200 for $99 on Amazon. Ssh to the router and run: opkg install snmpd
So I picked up this board on AliExpress for about $200 USD. Natrually the x79 chipset is NOT a dual CPU chipset, so yeah it’s one of those ‘not exactly 100% legit’ Chinese motherboards.
One thing about Chinese companies that many don’t sell directly to consumers, instead they sell on Tao Bao, Alibaba, or to foreigners, AliExpress. The company’s site is http://www.huananzhi.com, as they had written on the box. Yes you need the www. portion of the name, as again many things are… well dated on the Chinese internet.
High-speed USB3.0, SATA3.0 interface transmission speed is increased
PCI-E expansion slot*4
RJ45 Gigabit LAN interface
North Korean heat sink with HUANAN logo
Yes, I don’t get the whole Korean heat sink thing either. Anyways I thought it’d be fun to try so I ordered the thing. It took 3 days to get to my office in China, and an additional week to get from China to Hong Kong. I hear these things can take upwards of a month to arrive in North America.
Also worth noting is that they will not ship with a CMOS battery, so you need to supply your own CR-2032 battery, otherwise the board will not operate correctly.
The contents of the box are VERY minimal, but they did include 2 SATA cables, some CPU thermal paste, a very bare and … well not very good manual, a CD which I haven’t even tried to read, along with an IO shield.
I decided to pair this with a pair of E5-2620 v2‘s that I got for $40 USD shipped, as I didn’t want to initially spend a lot of money in case all of this just exploded or something. These were the ‘widest’ and cheapest processors I could find, I wanted a v2 E5 as they are faster then the first generation.
Also worth noting is that the board is only capable of driving v1 & v2 E5’s. And they need to be the E5-2 type, which support operating in pairs, unlike the E5-1 set. I have no idea if the E5-4’s aka 4-way part would work in a pair. Although it may be an interesting experiment to try.
The board apparently doesn’t support overclocking or anything that fancy.
Although it reports itself as an x79 based motherboard, it is in reality an Intel C602, based chipset. I don’t know if they are harvesting them off of recycled servers, or if they have located a giant cache of repair parts that have been pushed beyond 5 year warranties, so they are prime candidates for being re-purposed as end user motherboards. Nice things about these boards vs standard server boards is the inclusion of a Realtek HD Audio chip, VIA USB 3.0 controller, and even the nice spacing out of the slots so you could really use all the slots.
Since this is a dual processor board you really want a PSU with dual 8 pin power connectors, however as mentioned in the poorly translated manual, you can take a PCI-E 6 pin adapter, and place it into the 8 pin socket, just position it backwards so that the 12v+ pins are facing inwards.
It may look strange (well more so as I’m using an extension cable that is sadly more focused on aesthetics than function, but heh it was cheap), but rest assured it works!
Another thing to keep in mind is that since this board uses a server chipset, not a consumer one, just as it is using server processors, you will need server grade memory. In this case it’s REG ECC DDR3 based memory. I went with 1833Mhz parts, which are the fastest DDR3 parts they made. Although the processors I chose have a maximum frequency support of 1600Mhz, but the memory works fine when underclocked.
Another gotcha is the CPU fans. These need to fit the Intel Xeon 2011, but have support for the 2011 motherbards. Which unlike the consumer versions don’t have a separate plate to bolt to the underside, rather they screw in all from the top. I had purchased a pair of cheap heatsinks that were about the right size, but didn’t include any of the mounting hardware for a 2011 board. I picked up these GELID Phantom Black CPU’s for about $80 for the pair.
They are quite big, and include a pair of fans for each processor which will make the end build look a little crazy.
I didn’t want to spend a lot, and went with the cheapest PSU I could find to output more than 450 watts. Although it did turn on and run with the lower PSU the machine did shut off overnight for no apparent reason. I’ve been okay with the larger and cheap Antec NX 650 PSU.
Although, this is the older style ‘bundle o cables’ type of PSU which I’m not such a fan of.
If I had charged up a cordless screwdriver this would have taken a few minutes, but screwing in the heatsinks was a chore, and they really do dominate the boards real estate.
I thought I had a case, but it turns out that it was for normal ATX sized boards, and this is an E-ATX board so it simply will not fit.
Another nice server like feature is that the board has an LED readout for early post codes, as booting this board will take some time. I think with 32GB of RAM it’s almost a minute.
I took the SSD & Hard disk out of my MacPro 2010 and put them into the new machine, and it booted up right away. Once connected to the internet Windows 10 picked up the new hardware and downloaded and installed the board drivers as needed. Interestingly enough Windows 10 also wanted a new activation code as the CPU/Motherboard was changed, although it didn’t complain about it.
When it comes to jobs that can run in parallel this is an incredible build. Obviously single core performance at 2Ghz is. well. terrible. I know going to a 4Ghz max E5-2667 v2 won’t be exactly magic either, but there is something nice about having 32 threads. Running stuff like parallel compiles, compression and video encoding is a dream on these massively parallel machines.
Games, are ‘okay’. I get 60fps with Fallout 76 on this current 2Ghz build on medium settings with the 1050 video card.
I do plan on getting faster CPU’s after the Chinese New Year, as right now basically everything is shut down (it sucks being the only person in the office building, literally), and shipments wont’ resume for at least another week.
I picked up an ‘interesting Chinese motherboard, a dual LGA2011 board, some DD3 ECC memory, and 2 of the cheapest ‘widest’ chips I could find, the 6 core E5-2620 v2. The board cost me $200 US, the memory was $90 and the CPU’s were $40. Although the board is E-ATX, and that means I’ll need to get a new case as it won’t fit anything I have lying around.
I think I finally got the hang of Vegas. It’s taken far too long to get here, but I was hoping to have received the board much quicker as it shipped from 30km from here, but they did their best to NOT ship to Hong Kong.
I know it’s far too long, and far too maranding. Oh well it’s late and I’m just babbling like crazy.
So retrohun is doing their blog thing on github of all things, and the latest entry, is of course Xenix tales. As mentioned in comments on this blog & other places they found another driver for Xenix TCP/IP!
Going back years ago, the tiny NIC driver support for the elderly Microsoft/SCO Xenix 386 v2 included 3COMA/B/C and SLIP. However it’s been recently unearthed that D-Link had drivers for their DE-100 & DE-200 models, and as it happens the DE-200 is a NE-2000 compatible card!
That means that Qemu can install/run Xenix, and it can get onto the internet* (there is a catch, there is always a catch).
You can download the driver either from github or my password protected mirror. Simply untar the floppy under Xenix (tar -xvf /dev/fd0) and do the install via ‘mkdev dlnk’
Setting up the driver is… tedious. Much like the system itself. I found Qemu 0.90 works great, and is crazy fast (in part to GCC 3) even though Qemu 0.9’s floppy emulation isn’t good enough to install or read disks. With all the updates to Qemu 3.1 use that, it’ll read the disks, and allow for networking.
To give some idea of speed I ran the age old Dhrystone test, compiled by GCC 1.37.1 and scored the following:
Dhrystone(1.1) time for 5000000 passes = 8 This machine benchmarks at 625000 dhrystones/second
When compared to the SGI Indy’s 133Mhz R4600SC score of 194,000 @ 50000 loops that makes my Xeon W3565 322 times faster, under Qemu 0.90! And that’s under Windows!
Setting up the commandline/launching is pretty much this:
qemu.exe -L pc-bios -m 16 -net nic,model=ne2k_isa -net user -redir tcp:42323::23 -hda ..\xenix.vmdk added SLIRP adding a [GenuineIntelC] family 5 model 4 stepping 3 CPU added 16 megabytes of RAM trying to load video rom pc-bios/vgabios-cirrus.bin added parallel port 0x378 7 added NE2000(isa) 0x320 10 pci_piix3_ide_init PIIX3 IDE ide_init2  s->cylinders 203 s->heads 16 s->sectors 63 ide_init2  s->cylinders 0 s->heads 0 s->sectors 0 ide_init2  s->cylinders 2 s->heads 16 s->sectors 63 ide_init2  s->cylinders 0 s->heads 0 s->sectors 0 added PS/2 keyboard added PS/2 mouse added Floppy Controller 0x3f0 irq 6 dma 2 Bus 0, device 0, function 0: Host bridge: PCI device 8086:1237 Bus 0, device 1, function 0: ISA bridge: PCI device 8086:7000 Bus 0, device 1, function 1: IDE controller: PCI device 8086:7010 BAR4: I/O at 0xffffffff [0x000e].

In the file /etc/tcp the default installation does a terrible job of setting up the NIC. I changed the ifconfig line to this:
So there you go, all 20 Xenix fans out there! Not only a way to get back online, but to do it in SPEED!
Thanks to Mark for pointing out that there has been tremendous progress with version 3.1 of Qemu, and it’s TCG user speed is up to the 0.90 levels of speed (at least with dhrystone/Xenix), and it just takes a little (lot) of massaging to get up and running with Xenix with the right flags:
Naturally it’s full of TeX & Mathematical writing, along with trees and other ‘fun’ CS stuff.
While we are overall drowning in cat videos, and other uh ‘multimedia’ content, it’s still amazing the wealth of information that is available to the world (well the part of the world that can view YouTube).
I have no idea what the licensing is, but it’d be such a shame if it was hosted on additional platforms to make them available to the larger world.
So, I thought my mic was working but yeah it’s not. I’ve shot a bunch a footage, and did some capture stuff too. Turns out the audio I though I had working isn’t. I should have started with a 10 second short to get things ironed out.
I’m using old crap I’ve had lying around in this case, software wise, I’m using liteCam Game: 100 FPS Game Capture, which I guess is ‘okay’ for video capture. It runs on my 2006 MacPro so that’s great, but the video compressor it likes to use, the RSUPPORT MPEG4 Codec isn’t understood by the video editor I’m using, VEGAS Pro 15 Edit Steam Edition.
Editing was a fun time flailing around figuring out how to cut tracks, fade in/out add in other layers, and that’s when I noticed that my MIC wasn’t capturing anything. And I didn’t want to try to literally phone it in, so it’s a test video.
I was kind of crazy, and used the 2006 MacPro to make the video file. I should have known with the ‘blazing’ speed of 0.407x doing the trans-coding that this was going to be SLOW. Obviously dual Xeon 5130‘s @2Ghz isn’t really ideal for video editing today.
Clearly I need a bigger boat.
But just like running Fallout 76 on a 13 year old computer, it still runs. SLOWLY.
I wanted to some crappy branding/art things, but as I made a new channel I’m too much of a n00b apparently to set custom thumbnails. So I need to fluff it out or something I guess.
So here we go!
Consider it more of a process test, I need to get some lighting, and figure out what is up with my audio, maybe hit SSP and get an old audio board or something. Let me know how terrible it looks/sounds… I’m still working on transitions and stuff. I got Vegas on sale for a tiny fraction of the price, I guess it’s high time to use it.
Well this sucks. OSnews has been around for a long long time, and like other long in the tooth sites (slashdot sourceforge etc) things tend to stagnate, and then eventually get exploited.
To be perfectly honest, when contemplating what needed to be done to properly move the site to a new platform, I considered just throwing in the towel and going offline permanently. Revenues from advertising don’t cover expenses, and though this could probably be rectified by exploring more creative sponsorship approaches, I don’t have the time.
I can totally relate to this kind of thing. Once you’ve been doing something for over 10 years, and like me, doing it kinda poorly there becomes a demotivational wall. One thing that keeps me going however is the user comments. Granted any time there is a popular blip I can easily get 30k+ visitors in a day, but absolutely zero engagement. It’s the long term stuff however that actually gets the engagement, along with so many thanks for either spelling things out, or pointing people in the right direction for their projects or work.
The one thing that I think has artificially killed OSnews is that they had limited comments to articles for 2-3 days which I can tell you with some articles garnering over 100k hits is that the torrential storm of interest, and eventual comments and engagement comes later. Sometimes YEARS after the fact (The Opus #1 cisco hold music has garnered a TONNE of hits, follow up articles and a stereo re-release!. All of which started well over a year from publishing).
One thing I lament is that the auto-moderator ends up killing legit comments from time to time, but the amount of SPAM I get is unreal. I have over 1,000 from the start of this year to give an example of the volume. It’s a shame. As much as I’d like to be more like reddit or something more cultivated, I’d need humans working 24x7x365 in shifts to guard and watch the site, and I know I don’t have the funding for that, nor is anyone insane enough to do it for free, so enter the bots.
So yeah… Old sites end up drifting in and out of popularity as the years go by, especially if they don’t magically explode in popularity. News at 11 so they say.
Oh and update your passwords, if you haven’t done so already.
I was just alerted to this playthrough of Quake 2 for MS-DOS by TheSlipGateUser which showcases the game play under DOSBox.
Honestly I’m terrible at Quake, QuakeWorld and Quake 2, but it’s great to see someone who knows that they are doing, and more so that under emulation the game is holding up.
I know the MS-DOS port isn’t exactly the most popular in the world, although I suspect if it had been a thing in 1997 there would have been an audience with people that didn’t want to have Windows in the background as a distraction.
That said, any new people will of course want to check out the excellent (if I do say so myself!) series “Porting Quake II to MS-DOS“.
