Using Github Actions to audit pip library versions

I’ve got several Python and TypeScript projects scattered around that need constant dependency babysitting. Dependabot does a decent job but keeps missing Python pip security issues that pip-audit catches. The problem is pip-audit wants everything pinned to exact versions, but I prefer flexible >= constraints in my requirements files.

After getting tired of manually running security audits and then forgetting about them for months, I built this GitHub Actions workflow to handle it automatically. You can see it in action on my Shiny Quiz repository and Django demo application.

I’ve been doing more experimental stuff on my Windows 11 laptops lately - testing sketchy PowerShell scripts, trying out random software, and generally doing things that could completely wreck my system. While I have disk images for recovery, that’s a nuclear option that would cost me a day or two of rebuilding.

Turns out Windows has had a built-in solution for this exact problem: Windows Sandbox. It’s basically a lightweight, disposable VM that resets itself every time you close it. Perfect for testing things without the paranoia.

After my Windows 11 upgrade, I have a need for a quick way to start my screensaver but not lock my computer. So the Windows-L (lock) is not a desired options for this use-case. I want to quickly get back to my screen without logging back in.

I remember an old Windows NT tool and built-in MacOS feature called “Hot Corners” that let me do this by shoving my cursor to a corner of the screen. But I don’t want to load another tool for this. I’m using Power Toys “Mouse without Border” to link up a couple machines with virtual KVMs so the hot corners isn’t an option because of that.

So how do I solve this?

Upgrading to Windows 11 on my ThinkPad T480 laptops turned into a performance nightmare with some unexpected solutions.

My super lean Proxmox 8.3 testbed cluster running Ceph occasionally just decides to lockup a node based on it being incredibly limited on RAM and CPU. As much as I hate rebooting Linux/UNIX systems, this is a case where a nightly reboot of the nodes might help with reliability.

I want an extra ~350w of power available for a GPU that cannot run off PCIe bus power of 75w or 25w in some very old Dell Optiplex 990 Mini Tower nodes in my Proxmox cluster.

When one of my power supplies died earlier and I bought on eBay a NEW 750W Dell OptiPlex 9010 990 790 Power Supply Replace / Upgrade that was ~750w and the same form factor as those nodes PSU. This was just fast purchase to grab something that would ship the next day with no plan for an upgrade but I did pay attention that was both better and newer with a warranty.

So I have one machine that has the extra wattage available for a much better GPU like a Nvidia GeForce RTX 3060 12Gb.

My test Proxmox Cluster is used for testing and along the way I broke the Ceph Cluster part of it badly while doing a lot of physical media replacements. The test cluster is the right place to try out risky stuff instead of on my main cluster that is loaded up with my data. Fixing it often teaches you something but in this case I already know the lessons and just want to fast track getting a clean ceph cluster back online.

I need it back in place to test the Proxmox 8.2 to Proxmox 8.3 upgrade of my main cluster. So this is a quick guide on how to completely clean out your Ceph Cluster installation as if it never existed on your Proxmox Cluster 8.2 or 8.3 environment.

I swapped my physical disks around in my low-end testing hardware cluster. I have a mixture of soldered to the motherboard eMMC and an external USB3 Thumbdrive serving for a root file systems and external /usr volumes now. I would like a quick performance check on reading and writing to those file systems. I also don’t want to setup a huge performance benchmark suite or additional tooling. I just want some quick results at this point.

My basic question is what did I loose in this decision to break out my /usr out to an external USB3 drive. How much performance did I loose?

I have a pile of first generation Google Wifi units that I’m upgrading from to the latest Nest Wifi Pro that has WiFi 6e support. I want to reuse the older network devices for a secondary network but want greater control over them.

The Copy/Paste of an Event in the Outlook Calendar is no longer offered and cut off without much notice. I can confirm this in Outlook on the Mac as of 4Q-2024. This appears to also impact Windows users but they have a registry workaround to re-enable it. This is not a bug but functionality that was intentionally removed by Microsoft for reasons mentioned in their post below.

Outlook blocks copying meetings with “Copying meetings is not supported.”

This change drove me insane as I historically used calendar events to track my work and export it for hour accounting against projects. Using Tempo with Jira integration made this even easier. Before this change, I would just copy some work event from earlier and move it to a new time that had my project code and description of the project. It was a massively convenient piece of my workflow.

So, deep breath, I finally found another method to make copies of Events that was not obvious.

“Don’t bury the lede”

A working HP ProCurve Java WebUI screenshot to show that I got it working.

My earlier post HP ProCurve 2800 initial setup discussed an initial configuration of a network switch and mentioned in passing that I got the ProCurve Java WebUI working in a relatively safe manner. Here is how I put that together on a modern machine running Windows 10 Professional 64-bit.

^{_{WARNING: It should go without saying that you should not use the FireFox Web Browser from January 2017 that we are setting up here for the very old Java Web App supported on hardware released in 2004 and EOL in 2013 on the public internet. You will be hacked without a doubt in seconds. These are completely unpatched versions of two very very very old pieces of software. You have been duly warned.}}

I inherited, from a stack of old junk hardware, two Netgear Powerline 500 Nano XAVB5101 plugs. I thought I would try it out for a quick network connection between two floors in my new house using the existing power cabling.

Wow did I learn a lesson in a combination of networking and electrical power the hard way… with a repeatedly blown breaker.

An extended power loss for my primary Proxmox 8 cluster, while I was remote, took half of my cluster nodes out of commission into an unbootable state. This unbootable half of the cluster would not show up on the network after the power came back even with manual physical rebooting. The other half would boot up and show on the network. All the nodes had a second problem that they would not open a PVE WebUI Console Shell or show any output on any of the video output ports for either the Nvidia PCIe GPU or the Intel iGPU. So I have to figure out what looks to be a set of overlapping issues and clean up this mess. There were several lessons learned and re-learned along the way.

First, I need a “crash cart” to recover these to a bootable state. What is a “crash cart”, well that is usually a rolling cart found in a data center that you roll up to a broken server. They typically include some sort of serial terminal and/or a monitor, keyboard and mouse with a lot of connectors and adapters to hook up to random port for the equipment you are fixing. Mine includes adapters for VGA, DVI, DisplayPort, HDMI and both USB and PS/2 keyboard and mice. I’ve even thrown in a spare known good Nvidia K600 video card for troubleshooting graphic cards. A trusty and up to date Ventoy Bootable USB is sitting on there as well. I have a laptop that I could use for a serial terminal if we get to that point but I was hoping I didn’t need it since those are mostly for network equipment.

Here is my quickly thrown together trash can crash cart (TC³) for this adventure.

My earlier post for ProxMox 8.2.2 Cluster on Dell Wyse 3040s mentioned the tight constraints of the cluster both with RAM and DISK space. There are some extra steps involved in keeping a very lean Proxmox 8 cluster running on these extremely resource limited boxes. I am running Proxmox 8.2 and Ceph Reef on them which leaves them slightly under resourced as a default. So when the Ceph would not start up the Ceph Monitors after my upgrade from Proxmox 8.2.2 to 8.2.4, I had to dig a bit to find the problem.

Ceph Monitor will not start up if there is not at least 5% free disk space on the root partition. My root volumes were sitting right at 95% used. So our story begins…

Google Docs uses a URL based clipboard method to copy/cut and paste images and other media. That happens to works great between Google Docs but it completely fails when I try to take images from Google Docs to my Jekyll Posts when I need an actual image file. This is a small things but took some digging to figure it out for both Windows and MacOS.

I have been using the Dell Wyse 3040 as awesome little systems for my Tailscale nodes in my multiple joint homelab networks. These systems are super low power consuming and physically small enough to just plug and go. Truly, deploying a WireGuard®-based VPN solution could not be any easier. I have four of these units connecting my homelab networks across three geographically diverse locations.

This is an out of place post but I figured if setting up Touch ID with sudo on my MacBook Pro stumped me that it would cause others issues and worth a quick write up. Also worth having around when I get a new MacBook Pro in the future.

So to start, I use a MacBook Pro M2 Pro for my daily driver machine at work. It is the closest I can get to a Linux machine in the office. I end up using sudo frequently enough that I liked the idea of Touch ID rather than type a password in a dialog. I encountered a couple of hiccups along the way with tmux, iTerm2 and DisplayLink that had to be fixed.

What is Ceph? Ceph is an open source software-defined storage system designed and built to address block, file and object storage needs for a modern homelab. Proxmox Virtual Environment (PVE) makes creating and managing a Hyper-Converged Ceph Cluster relatively easy for initially configuring and setting it up.

Why would you want a Hyper-Converged storage system like Ceph? So your PVE that runs Virtual Machines and Linux Containers has a highly available shared storage service making them portable between nodes in your cluster of machines and thus highly-available services.

There is a significant learning curve involved in understanding how the pieces of Ceph fit together which the Proxmox documentation does a decent job of helping you along. Proxmox VE sets some decent defaults for the Ceph Cluster that are good for an enterprise environment. What they do not do is help you set default to reduce wear and load on your Homelab system. This is where I am going to try out a few things to reduce load and wear on my Homelab equipment while maintaining a relatively high-availability environment.

My post on Ceph Cluster rebalance issue from earlier was from figuring out issues in an unbalanced cluster from a strange data loaded into a cluster. This post is focused on a regular running cluster that needs some optimization for the homelab.

I want a place to test and try out new features and capabilities in Proxmox 8.2.2 SDN (Software Defined Networking). I would also like to be able to test some Ceph Cluster configuration changes that are risky as well. I do not want to do it on my semi-production Proxmox 8.2.2 Ceph enabled Cluster that I have mentioned in earlier posts. With 55TiB of raw storage and 29TiB of it loaded up with content, that would be painful to rebuild or reload if I made a mistake during my testing of SDN or Ceph capabilities.

The Dell Wyse 3040 is a nifty little machine that is extremely small and a low power consumer. They are however not without issues. This is my foray into trying to get a couple of them working on my homelab. I bought a couple in early March 2024 based on watching Apalrd’s videos Dell Wyse 3040 Thin Client Teardown and Installing Proxmox VE 7 on Debian Bullseye with the various Dell Wyse thin clients.

I have collected nine (9) mostly functional Dell Wyse 3040 thin clients for use in my experimentation with Proxmox Clusters and SDN and Site-2-Site VPN configurations with Tailscale. Yes, I know I have a problem. :)

On the upside, they are very small low power consuming Debian 12 servers that have a 1Gbps NIC and run headless nicely once you fix the BIOS settings and Debian configuration correctly. What is not nice is their CMOS batteries are all mostly dying on me and their connector is a odd type that is not supported by many vendors and are between $8-$12 USD to replace. For example the Rome Tech CR2032 CMOS BIOS Battery for Dell Wyse 3040 is about $9.89 USD as of posting this. This bothers me intensely as the actual CR2032 can be picked up for well under a dollar ($1 USD) each at LiCB CR2032 3V Lithium Battery(10-pack) for a pack of 10 for $6 USD. Also, I’m picking these units up with power adapter for between $20 and $45 on eBay and the $10 bite jacks my price per unit up a good bit. So what to do?

I have a significant investment in my WSLv2 Ubuntu 22.04.3 LTS installation. It has my Nvidia GPU setup nicely integrated and several machine learning demos and tests I’ve built and use for keeping current on machine learning. With Ubuntu 24.04 LTS released, I now want to play around in the newer version but don’t want to move or worse copy my entire set of models and repositories across. I have well over 500Gb of content and absolutely don’t want two copies of those floating around. I’m looking for a solution to this and figure others have encountered it.

We live in a world with a penny ($0.01 USD) per GB of storage. I just found this bare drive MDD (MD20TS25672NAS) 20TB 7200 RPM 256MB Cache SATA 6.0Gb/s 3.5” Internal Hard Drive (for NAS, Network Storage) - 5 Years Warranty (Renewed) for $199.99 USD. I also found Avolusion PRO-X USB 3.0 External Hard Drive (Black) - 2 Year Warranty (20TB) for $229.99 $219.99 USD with the USB C enclosure.

I am in the process of building a Proxmox 8 Cluster with Ceph in an HA (high availability) configuration using very low-end hardware and questionable options for the various hardware buses. I’m going for HA, cheapfrugal and reuse of hardware that I’ve gathered up over the years.

Over the COVID lockdown, I was running a Plex Media Server (PMS) on an older Dell Optiplex 390 SFF Desktop that I cobbled into it several Seagate USB3 portable drives that I just slapped on it as I needed more space. It hosted my extensive VHS, DVD and BluRay library as I ripped them into digital formats. To improve the experience I threw a Nvidia Quadro P400 into the mix and a PCIe USB3 card for faster access to the drives. Eventually, I had some drive issues and wanted to get some additional reliability into the mix so tried out Microsoft Windows Storage Spaces (MWSS). Windows and the associated fun I had with MWSS left me incredibly frustrated and I was trying to make an enterprise product work in a low-end workstation with a bunch of USB drives. The thing that made me fully abandon MWSS was the recovery options when you had a bad drive. MWSS probably works well with solid enterprise equipment but was misery on the stuff I cobbled together. So exit Windows OS.

For about ten (10) years, I had run an VMWare ESXi server that let me play with new technology and host some content and services. I let it go awhile back while I was in graduate school and working full-time but have missed this as an option ever since. So adding a homelab server or cluster will let me get some of that back.

Adding another SSD Drive

In my etermal tinkering with my Lenovo Thinkpad T480s, I have continued the trend of adding new features. So earlier, in A new to me but old laptop and New Laptop update, I threw out a bunch of enhancement options. Some of those I’ve done and some I left on the backlog as things that just cost too much on my metric of usefulness per dollar. The WWAN SSD for extra storage was one of those that just seemed like a bad bang-for-the-buck for storage. I also like the option to add a SIM card and have cellular network available in case I have to go back to consulting on the road.

How to run Github Pages locally in my Microsoft Windows 10 Pro WSLv2 Ubuntu 22.04 LTS environment and using Visual Studio Code to modify the contents. I’m not a Ruby or Jekyll expert by any means but just wanted a quick guide on running my Github Pages website locally to review them before pushing to this website. Seemed like an easy enough thing but there were a couple of hiccups to sort out so thought I’d write them down for future me when I try this again.

This should also lets me test out new plugins, new versions and changes to templates without breaking the public website. I’m still sorting out how to do the abstracts and formatting of the archive pages correctly.

Get access to switch console

You will need a console serial cable to get into your HP ProCurve 2800 switch.

Here is the one I bought from Amazon OIKWAN - USB Cisco Console Cable, USB to RJ45 Console Cable which has been useful on some other project as well. I have a break out for the RJ45 to let me use this on an old BlackArmor NAS and to interface with some robotics equipment. You mileage may vary but this one works great for me.

This is the ProCurve 2810-24 that is all 1Gbps ports with four SFP (not SFP+) ports that you can use with fiber or DACs. I bought three of these so I have a SAN and two home networks… then I picked up another one as a spare because it was less than $25 on eBay. So I’m all in on this switch for my home networks.

This is rough draft that I’m just pushing out as it might be useful to someone not stay in my drafts folder forever… Good enough beats Perfect that never ships every time.

I think I have mentioned my ProxMox/Ceph combo cluster in an earlier post. A quick summary is it consists of a five (5) node cluster for ProxMox HA and three of those nodes have Ceph with three (3) OSDs each for a total of nine (9) 5Tb OSDs. They are in a 3/2 ceph configuration with three copies of each piece of data allowing for running if two nodes are active. Those OSD / hard drives have been added in batches of three (3) with one added on each node as I could get drives cleaned and available. So I added them piece meal in a sets of three OSDs, then three more and finally the last batch of three. I’m also committing the sin of not using 10Gbps SAN networking for the Ceph cluster and using 1Gbps so performance is impacted.

Adding them in pieces as I also loaded up the CephFS with media content is what is hurting me now. My first three OSDs that are spread across the three nodes are pretty full at 75-85% and as I added the next batches, the cluster has never fully caught up and rebalanced the initial contents. This impacts the results of my ‘ceph osd df tree’ results showing I have less space then I actually have available.

Something that I’m navigating is Ceph will go into read-only mode when you approach the fill limits which is typically 95% of space available. It starts alerting like crazy at 85% filled with warning of dire things coming. Notice in my OSD status below that I have massive imbalances between the initial OSDs 0,1,2 versus 3,4,5 and 6,7,8.

This is a meandering post without an immediate happy outcome.

I am working on a five node ProxMox 8.1 cluster with three nodes as a Ceph cluster to host my media collection. I’m learning a bunch about Ceph and Proxmox which I’ll post about later. The media collection I am importing into Ceph is a little over 16Tb from ripping my VHS, DVD, BluRay collections of movies and tv shows. Movies end up being less than a third of that content.

This is a project I’ve been thinking about for a long time… how to get 10gbpe+ networking in a homelab without breaking the bank.

First option is just getting some DAC Cables and dual port 10Gbpe NICs then build a point-to-point ring network. That is relatively cheap and would set me up for future switched networks. DACs could be swapped out for GBics that use copper (thermal issues) or fiber (delicate).

Next is a relatively cheap at a couple hundred dollars switch with likely a low number of SFP+ ports. This is ~$200-$500 with anywhere from 2 to 16 ports at 10Gbps. Often switches with 10Gbps advertised only have one or two ports at that speed so shop carefully. You still have the cost of the NICs and cabling but only need one port on the NIC.

Lastly, you could go all in with an enterprise switch like the HP ProCurve 5406zl which is a module hosting monster of a switch. These are massively upgradable but come with a lot of complexity to set up and manage. They are also incredibly loud (intended for server rooms) and suck a ton of power which generates lots of heat (thermal load). These are getting cheaper but are heavy to ship and still usually several hundred dollars with modules that can cost thousands. Don’t expect a warranty on these as they are being pushed out of enterprise usage as end of life.

I have developed something interesting for my graduate class in Computations Photography for the final project. As background, for the class we had an assignment in which we used the Microsoft Photosynth service to generate a 3D walk thru of an area by uploading several hundred photographs. On the back-end the Photosynth web service does feature extraction on all the photos and then related the photos in three dimensions to each other and the feature points. This generated a point cloud of related points between the photos.

I’m live with the Lets Encrypt certificates for the blog.mcgarrah.org website. This has been awhile in the making and I’m kind of excited. I’m on a legacy environment with Ubuntu 12.04 LTS so part of the process is manual but certificate update just happens nicely. Updating the Apache config files has a little bit of effort but nothing too bad.

Artificial Intelligence for Robotics (CS8803-001)

Associated with Georgia Institute of Technology

Fall Semester 2015

The goal for the final project in CS6475 AI for Robotics was to create a robotic platform to investigate computer vision technology. The platform included an Arduino with sensors and motors and a Raspberry Pi 2 for the vision and primary control system. The project URL is a video channel that shows the progress and challenges.

For an assignment in my robotics class, I need to have an autonomous system react to the environment around it. Reacting can be as simple as flashing a LED if a sensor detects a change.

I have two objectives for the Raspberry Pi 2 (RasPi2) and those are to take a picture using the 5mp webcam and flash a LED. I could use the standard GPIO pins and setup a separate LED but noticed we have two perfectly good LEDs built into the board.

Reading on these built-in LED did not elicit any clear way of interacting with them from the regular Linux documentation. I informally called them the Red Power and Green DiskIO LEDs. It was by reading the headers to the source for Windows 10 for Raspberry Pi 2 that I found the GPIO pinouts for these two LEDs. They are:

35 Red Power LED
47 Yellow DiskIO LED

I needed a quick understanding of the Python 3.3.0 datetime functionality to do a difference in times across days. Python make it amazingly easy.

import datetime
from datetime import timedelta

# get current timedate
now = datetime.datetime.now()
print "now: " + str(now)
# get one day of time oneday = timedelta(days=1)
# make one day in the future and past
tomorrow = now + oneday
yesterday = now - oneday
print "tomorrow: " + str(tomorrow)
print "yesterday: " + str(yesterday)
# compare times
if now < tomorrow:
  print "now < tomorrow"
elif now > tomorrow:
  print "now > tomorrow"
else:
  print "now must be equal tomorrow"
if now > yesterday:
 print "now > yesterday"
elif now < yesterday:
 print "now < yesterday"
else:
 print "now = yesterday"

The expected results are:

CMD> python time.py
now: 2015-03-19 14:30:31.083000
tomorrow: 2015-03-20 14:30:31.083000
yesterday: 2015-03-18 14:30:31.083000
now < tomorrow
now > yesterday

I hope this helps someone.

I’m working on a problem with Windows 2012 RTM server running an IIS web service. To load balance it, we decided to use Rackspace Cloud Load Balancers. Periodically we receive some errors that appear in the system event logs.

"A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 40. The Windows SChannel error state is 1205."

I’m beginning to setup enough infrastructure that a wildcard certificate would be nice but I’m uninterested in paying several hundred dollars a year for that certificate. The free certs that used to be around just are not there anymore so far as I can see. My goal is to setup SSL certificates for both my email server and all the virtual host web sites I’m hosting under my mcgarrah.org domain for less than a hundred dollars a year.

Okay, full disclosure, I hate change or at least useless change. Skip over the rant to the HowTo fix Skype if you want.

I found a fun little website to make fake diplomas. This struck my funny bone.

I hung it in my office next to my Bachelors degree in Computer Science and waited for someone to read it. It is the gift that keeps on giving.

I’m taking a graduate course in computer networking at Georgia Tech. The tools they are asking us to use are all open source and allow for some pretty interesting projects.

One such tool is the Mininet software that allows for building realistic virtual networks with real switches, routers and applications running on a single system. We are using a virtual machine that contains a copy of the Linux operating system and the virtual networking software. So far we are encountering minor issues with the OS and VM software.

One of this issues I ran into with bouncing between VMware Player 6.0.3 and my VMware ESXi 5.5u1 server is the hardware level of the virtual machines. ESXi 5.5 without the vSphere licence will not manage the newer virtualHW.version = “10″ virtual machines.

Some addition research into WP plugins have a couple more worth reviewing.

I’ve been back to the toolchain for ESXi again and had some success.

I was really getting frustrated with my lack of success in building the VMware ESXi 5.5 toolchain and compilers. It was a multi-week effort and I’m usually able to get something like that working eventually. I took a couple of month break from it while I worked on some other things including this website(WordPress) and my email servers. This gave me some perspective.

Researching plugins and extensions for WordPress has been an experience.

I’ve got a pile of certifications that I’ve accumulated over the years.

Below are my Redhat Linux, Microsoft, Sun Solaris, Nortel Networking and ITIL cert logos. I think the RHCE and Sun Solaris certs were probably the hardest of this bunch.

Here are my SAS certifications that took me six months to complete on my own time. The Clinical Trials Programmer exam was by far the hardest of this set of tests. I mostly use my SAS experience now to port software to R.

I’m interested in the security CISSP and VMware VCP5 certification but have not had the inclination to spend the money or time yet.

Hajo on the BlackArmor Forums has an older posting about getting Debian Linux 5.0 (Lenny) installed on BA NAS 110/220/4x0. This is not a port that includes the kernel but simply a minimum install that gets the system setup to install binaries out of the Lenny EABI ARM platform. The kernel that comes with the BA NAS is compatible with those binaries. The newer kernel for the Debian 6 or higher is not compatible with the BA NAS. This has some limitations but offers a way to get to some newer software pre-compiled. I don’t want to loose the existing functionality on my test system but the draw to DLNA services is pretty strong right now.

To top it off, Debian has a nicely setup cross-compilation setup documented for people working on non-Intel platforms. This offers a way to compile newer software without killing myself anymore on building the entire compiler and supporting software myself.

The goal has always been to make the NAS device useful and I want to play my movies off it to my TV upstairs so this might be the next thing I play with on the development NAS.

I figured out something simple but neat on the Black Armor NAS 110 (BA-NAS110) device. It has rsync a powerful file-system replication tool from UNIX.

Caveats are that in order to do this you must have root on the device and a ssh connection with the command line. I’ll write a friendly doc on how to get ‘root’ later. (Just search for Hajo Noerenberg’s work on the subject sans the friendly write up if you want to do it now.)

So, the BA-NAS110 is capable of using rsync from the command line to replicate its data to another NAS or Linux system if you have root on the system. Getting it setup was simple enough but knowing that the rsync daemon and client were on the systems was the trick.

You have to create a rsyncd.conf file since there isn’t one pre-built. Syntax is common to the typical rsync 3.0.4 version.

I found something fun.

The Seagate NAS (Network Attached Storage) that I’ve been using at my house is running an embedded Linux. A NAS is a big network hard drive you can share between computers. I got a root account on it and have found a whole world of fun that could be done in there. Root is the master administrative account for UNIX systems that let you do extra things beyond the normal.

First steps is getting a functional toolchain and then build some trivial tools. The goal would be to have a full set of GNU tools available in a package format for people to use. I want to publish a full working OpenSSH with scp support and rsync for this thing as a starting point. Maybe add some features for NFS. Just digging around on this thing reminded me how much I enjoy hacking on hardware.

“Senior Design: NetApp iSCSI with RDMA/TOE” (Fall 2010 Capstone Project)

Aug 2010 - Dec 2010

Summary: Develop a methodology for 10Gbps iSCSI that utilized RDMA and TOE to reduce primary CPU and memory usage. Document and managed the project as a team leader. The resulting iSER implementation was utilized in a related NetApp Phd project at the University of Bangalore India.

This is a very old set of notes but might be useful for a developer dealing with Microsoft Visual Studio 6.0 for DOS and Windows 16-bit coding. This is from the era of Borland and Zortech Compilers being in play. I migrated this from my defunct darkmagic.org website.
