Explain OSI Model Layers Briefly.

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers. Each layer serves a specific purpose and communicates with the layers above and below it. Understanding the OSI model is crucial for networking professionals, and it's often covered in Networking Courses offered by Networking Training Institutes.

At the bottom of the OSI model is the Physical layer, which deals with the physical connection between devices, including cables, connectors, and transmission rates. Above that is the Data Link layer, responsible for error detection and correction within the physical layer. Next is the Network layer, which manages routing and forwarding of data packets.

The Transport layer ensures reliable delivery of data between devices, handling issues such as data segmentation and reassembly, as well as flow control. Above that, the Session layer establishes, maintains, and terminates connections between applications. The Presentation layer is responsible for data translation, encryption, and compression.

Finally, the Application layer provides interfaces for application services and network-aware applications. It is the layer closest to the end user. By grasping the functions of each OSI layer, networking professionals can troubleshoot issues more effectively and design robust network architectures. Networking Training Institutes offer comprehensive courses covering the OSI model and its practical applications in networking scenarios. Understanding the OSI model is fundamental for anyone pursuing a career in networking.

Wood Engraving Wednesday

James G. Todd, Jr.

Two years after his retirement as an art professor at the University of Montana, noted wood engraver James G. Todd, Jr. (b. 1937) published his memoir, Tales of the Cold War (Helena, Montana: Drumlummon Institute, 2022), recalling his experiences related to superpower tensions after the Second World War from 1944-1991. These engraved portraits are of some of the individuals he encountered during a 1984 visit to China for a Montana-Hangzhou exchange:

Once Don and I were in the hands of our academy hosts, we were secure and controlled. Their two objectives were to make a favorable impression on us, and keep our contacts with individual Chinese as limited as possible. We met many Chinese but these contacts were almost always under regular scrutiny.

Born in Minneapolis, and raised in both Minneapolis and Seattle, Todd has spent most of his adult life in Montana as a student, teacher, and artist. He became an elected member in two international British organizations, the Society of Wood Engravers (SWE) in 1986, and the Royal Society of Painter-Printmakers in 1997. He is also a member of the American Wood Engravers' Network (WEN) , and our copy of this book is warmly inscribed to WEN's founder Jim Horton, from whom we also received this book as a donation. Todd writes:

Jim, . . . your leadership of WEN and my membership was an important part of my career. [Canadian engraver]Jim Westergaard and I worked in isolation as wood engravers for many years, and then we became part of the wood engraving world through WEN and the SWE. . . . I came to know your work and that of many fine American engravers I otherwise would have never known.

I always felt that Black Hat, from CN's Villainous, was the most endearing and likably unlikable in the very first batch of shorts, and the later stuff like the pilot and orientation videos, took him in a less interesting direction imo. While I can get behind the idea of a near infallible threat who plays the role of a mysterious antagonist even for his employees, I originally read him in the first batch of shorts as still an incredibly competent villain and businessman with immense power and the walk to back his talk, but still prone to error, bad luck, and a good helping of humble pie whenever he gets too in over his head. I honestly prefer that for him

Black Hat: So, those are our latest amazingly antagonistic products! Remember, this can go one of two ways: you don't buy from me while your peers in the villain market capitalize on this offer and they- and I - get all the benefits, or you order now and get the goods! Either way, of course, I get rewarded, so at least you would too if-- what, what IS it, Flug, can't you see that I'm giving a spiel- ANOTHER ELECTRIC BILL?!?! [slams head on desk] Ouuuuughhhh, I, hate, my life.

man oh man i have so many thoughts about how insistently (and i think kind of blindly/uncritically) my university pushes us to frame absolutely every type of learning experience we offer to students in the language of "career readiness" and "career-connected learning" and "professional development." i totally get that we have a large first-gen student population who are making a big investment of time & money in a college degree and who want to be sure that doing so will grant them access to greater socioeconomic mobility. and i DO think it is important for us to think about like, ok, long-term, what comes after these experiences or after this four years in college, and what can we be doing to set students up for success as they transition out of college and into the rest of their lives. but like. idk man. i find it really bleak sometimes. just this relentless messaging that the only thing that matters in your adult life is how competitive you are on the job market. and i also think it pushes us to just like, kind of warp or distort the things we are offering students to make them fit under that rubric, or that particular framework for valuing things? like if we want to convince a student to study abroad we can't be like, living abroad is one of the most amazing things you can do. it's so fun/scary/exhilarating/awesome and it will expand your horizons in ways you can't even anticipate and it will expose you to different ways of seeing the world and you will get to interact with people whose perspectives have been shaped by totally different cultures & contexts and it will help you become more independent and more confident in your ability to handle unfamiliar situations and it will give you stories you will remember all your life and you will build strong friendships with the people you meet and you will take cool pictures or buy little knickknacks that remind you of those experiences in your daily life forever and it will motivate you to travel more and when/if you have kids of your own you will probably make it a priority to travel with them if you can or to encourage them to study abroad when they're older because you know how amazing that experience is and you want them to have access to those kinds of life-changing opportunities. like instead of saying any of that we have to say oh this will develop your skills in time management and project management and professional communication with your supervisors and it will give you something impressive to talk about on your resume or in job interviews and blah blah blah. or even if you use a more capacious definition of career readiness that focuses more on habits of mind (like, in the workplace you will sometimes have to navigate complex situations where expectations are not fully clear! you will also likely have this experience living abroad!), it's still just like... idk man... i find it so reductive lol like yeah sure but "get a skill that applies to your job as a project manager or an IT professional or whatever" just feels so much... Less... than the more humanistic appeal to like, this will enrich your life in so many ways, and you will, through these experiences, just become an all-around more emotionally mature, confident, and interesting human being who has engaged in an experience that challenged you and helped you grow. but then i am all in on the humanities and humanism in general so maybe i am biased here and someone who wants to be a software engineer or whatever would be wholly unmoved by that kind of appeal. idk. anyway. it looks like our team is going to be subsumed into our career center in the next year or two so like. what can you really do except to inwardly say "wow i kinda hate this"

Cecilia: had my big audition and I. . . (imitates a gunshot with her fingers) killed it!

Dark phantom: that’s great! Flug: good for you.

Val doom: excuse me I was in the middle of my story.

Cecilia: you found the paper clips, terrible story, anyway~~ the cast liked me so much I got offered the lead! It’s the role of a lifetime, much better than my role as Juliet at grade school; oh knife (grabs a fork) take me and let me die~. . . bleh~ (stabs food on table)

Val doom: what do you think you’re doing? That’s the big piece.

Cecilia: yeah. So?

Val doom: the big piece goes to the queen bee AKA me~

Cecilia: and what makes you the queen bee?

Val doom: um, everything~ I’m smarter than you, I’m stronger than you, I’m more ‘developed’ then you (small jiggle as two boys look over) easy boys~ (she winks to them; teasing them.)

Cecilia: sorry val, but anything you can do, I can do better.

Val doom: I can do anything better than you. 

Cecilia: no you can’t!

Val doom: yes I can!

 Flug: Clearly, they have repressed sеxual feelings for each other that they're channeling into hostility.

Ghoul: how’s that villain psych 101 class going?

Flug: it’s only day three, but I pretty much understand how the whole world works now.

Matt Gertz at MMFA:

In a Sunday rant on his Truth Social platform, Donald Trump lifted up a bogus claim of widespread election fraud during the 2020 presidential election, which he sourced to a guest of Tucker Carlson, the right-wing media star and sometime Trump adviser.  “An interview by Tucker Carlson of an election expert indicates that 20% of the Mail-In Ballots in Pennsylvania are fraudulent,” Trump wrote. “Here we go again! Where is the U.S. Attorney General and FBI to INVESTIGATE? Where is the Pennsylvania Republican Party? We will WIN Pennsylvania by a lot, unless the Dems are allowed to CHEAT. THE RNC MUST ACTIVATE, NOW!!!” Throughout his campaign, Trump has lied about election fraud costing him the 2020 race and baselessly warned that any defeat in 2024 could only be attributed to cheating by Democrats. On Saturday, he pledged that “WHEN I WIN, those people that CHEATED will be prosecuted to the fullest extent of the Law, which will include long term prison sentences.”

The former president’s social media screeds illustrate the state of the right-wing media bullshit pipeline Trump used to try to steal the 2020 presidential election, which he will use again to delegitimize the 2024 election if he loses it.

Trump’s claim originates with a bogus poll from a right-wing think tank’s “Socialism Research Center”

Trump appeared to be referencing an April interview Carlson conducted with Justin Haskins, a think-tanker at the right-wing Heartland Institute, as Mediaite noted.  Carlson introduced Haskins by falsely claiming that Trump faced federal criminal prosecution simply because he suggested “the 2020 presidential campaign was not on the level,” asserting that “it’s worth denying the legitimacy of that election,” and alleging that a poll Heartland conducted demonstrated that widespread voter fraud did take place.  Haskins went on to detail the poll, in which respondents who said they voted absentee or with mail-in ballots in the 2020 election were asked if they engaged in various illegal actions, like voting in a state in which they were not a legal resident or forging the signature of someone else on their ballot.  “All told, it’s at least — and I say at least — 1 in 5 mail-in ballots involved some kind of fraudulent activity,” he concluded.

[...] Trump’s Sunday social media post demonstrates that the pipeline that brought election fraud lies to the former president in 2020 is still online as the 2024 election approaches. But the right-wing ecosystem is more fractured and competitive than it was, as former Foxers like Carlson have left the network and attracted their own audiences. Given this ecosystem, we are likely to see the varied outlets and personalities — competing for Trump’s attention and favor — push each other to endorse ever-less-credible claims to support the GOP nominee’s contention that he can lose only if the election is stolen.   With the 2024 election shaping up to be a close one, the Republican Party and its propagandists turning election denial into a core value, and the right-wing ecosystem primed to rerun the demagoguery that helped bring about an insurrection, the next few months are looking grim.

Donald Trump’s election fraud lies that he parroted on TRUTH Social Sunday came from Justin Haskins, a member of the right-wing climate denialist think tank Heartland Institute. Haskins appeared on Tucker Carlson Network’s Tucker Carlson Uncensored this April.

Engineers Achieve Multiplexing Entanglement In Quantum Network

— By California Institute of Technology | February 26th, 2025

Laying the groundwork for quantum communication systems of the future, engineers at Caltech have demonstrated the successful operation of a quantum network of two nodes, each containing multiple quantum bits, or qubits—the fundamental information-storing building blocks of quantum computers.

To achieve this, the researchers developed a new protocol for distributing quantum information in a parallel manner, effectively creating multiple channels for sending data, or multiplexing. The work was accomplished by embedding ytterbium atoms inside crystals and coupling them to optical cavities—nanoscale structures that capture and guide light. This platform has unique properties that make it ideal for using multiple qubits to transmit quantum information-carrying photons in parallel.

"This is the first-ever demonstration of entanglement multiplexing in a quantum network of individual spin qubits," says Andrei Faraon (BS '04), the William L. Valentine Professor of Applied Physics and Electrical Engineering at Caltech. "This method significantly boosts quantum communication rates between nodes, representing a major leap in the field."

The work is described in a paper published on February 26 in the journal Nature. The lead authors of the paper are Andrei Ruskuc (Ph.D. '24), now a postdoctoral fellow at Harvard University, and Chun-Ju Wu, a graduate student at Caltech, who completed the work in Faraon's lab.

Just as the internet connects with the classical computers we are accustomed to using today, the quantum networks of the future will connect quantum computers that exist in different physical locations.

When working with the quantum realm, researchers are dealing with the miniscule scale of individual atoms and of photons, the basic particles of light. At this scale, matter does not behave according to classical physics; instead, quantum mechanics are at play.

One of the most important and bizarre concepts in quantum mechanics is that of entanglement, where two or more objects such as atoms or photons are inextricably linked regardless of their physical separation. This connection is so fundamental, that one particle cannot be fully described without reference to the other. As a result, measuring the quantum state of one also provides information about the other, which is key to quantum communication.

In quantum communication, the goal is to use entangled atoms as qubits to share, or teleport, quantum information. The key challenge that has thus far limited communication rates is the time it takes to prepare qubits and to transmit photons.

"Entanglement multiplexing overcomes this bottleneck by using multiple qubits per processor, or node. By preparing qubits and transmitting photons simultaneously, the entanglement rate can be scaled proportionally to the number of qubits," says Ruskuc.

In the new system, the two nodes are nanofabricated structures made from crystals of yttrium orthovanadate (YVO4). Lasers are used to excite ytterbium atoms (Yb3+), a rare-earth metal, within these crystals, causing each atom to emit a photon that remains entangled with it. Photons from atoms in two separate nodes then travel to a central location where they are detected. That detection process triggers a quantum processing protocol that leads to the creation of entangled states between pairs of ytterbium atoms.

Each node has many ytterbium atoms within the YVO4 crystal, so there are plenty of available qubits. However, each of those atoms has a slightly different optical frequency caused by imperfections within the crystal.

"This is like a double-edged sword," Ruskuc says. On one hand, the differing frequencies allow the researchers to fine-tune their lasers to target specific atoms. On the other, scientists previously believed that the corresponding differences in photon frequencies would make it impossible to generate entangled qubit states.

"That's where our protocol comes in. It is an innovative way to generate entangled states of atoms even when their optical transitions are different," Ruskuc says.

In the new protocol, the atoms undergo a kind of tailored quantum processing in real time once the photons are detected at the central location. The researchers call this processing "quantum feed-forward control."

"Basically, our protocol takes this information that it received from the photon arrival time and applies a quantum circuit: a series of logic gates that are tailored to the two qubits. And after we've applied this circuit, we are left with an entangled state," Ruskuc explains.

The team's YVO4 platform can accommodate many qubits—in this work, each node contained approximately 20. "But it may be possible to increase that number by at least an order of magnitude," says co-author Wu.

"The unique properties of rare-earth ions combined with our demonstrated protocol pave the way for networks with hundreds of qubits per node," Faraon says. "We believe this work lays a robust foundation for high-performance quantum communication systems based on rare-earth ions."

Additional Caltech authors of the paper, "Multiplexed Entanglement of Multi-emitter Quantum Network Nodes," are graduate student Emanuel Green; AWS Quantum Postdoctoral Scholar Research Associate Sophie L. N. Hermans; graduate student William Pajak; and Joonhee Choi of Stanford University, a former postdoctoral scholar from Faraon's lab. Device nanofabrication was performed in the Kavli Nanoscience Institute at Caltech.

If I had to choose between cutting off my hand and redoing grad school apps, I'd seriously consider the hand. Be gentle with yourself, it's a fucking slog. What kind of program are you looking into?

Thank you for the reminder to be gentle. This shit has been stressful, and having for various reasons only about a month and a half to actually do focused work on applying has SUCKED. Not looking forward to potentially having to do this again in the future (it's complicated but I'll explain why in a sec), but I am SO looking forward to two weeks from now when these applications are in and it's out of my hands, as much as the waiting game itself sucks in its own way.

As for programs, I don't want to get too specific. I was a double major in undergrad, and I'm not exaggerating when I say I've literally never met anyone else with those two specific majors. (Ftr one is a STEM field and the other in the humanities.) I want to keep studying both in some capacity in the future, but to make a long story short I'm stuck in a position where I have to hold off on applying to the program in the humanities for now.

As annoyed as I am about the 'long story' part of that, I'm totally fine with prioritizing the program in STEM for now. Hell, in some ways that's a good thing given the limited amount of time I have to work on applications. But at the same time, I've greatly limited the number of schools I'm applying to so I can focus on creating well-tailored applications for their specific programs and faculty, and that means each potential rejection would leave me with a far smaller share of options. It's a bit of a risk, but damn it I'm trying my best to show how strong of a student I've been and that I would work well with their specific people. Hopefully things work out in the end.

I hope your own efforts have paid off too, wherever life has taken you.
