Job Hunting Tips: Say What??

You Need a Major career move, promotion, complete overhaul, change to something new altogether. Now what? Here are some steps to follow:

1. Target companies you’d like to work for. Research them, not only the bottom line, but their products (use cases), company culture, and the people who work there, especially people on the hiring team and HR. LinkedIn is a great resource for this.

2. Follow the companies AND the people at the companies, start commenting on their posts. These comments should add value to what was already said, and also tag the person who posted the information, state or reword what they’ve stated and add to it. Keep going, it’ll take time to establish a connection with people. Don’t ask for any recommendations or help, add validation to what was posted.

3. Find a unique issue that you can solve for the company. Then, begin to formulate a pitch deck for your solution. Find out what you can improve. Make your pitch about helping them, not about yourself. Find the opportunity to present your solution.

Make sure you find out what the Company’s goals and current/future initiatives are. Be the Solution /Bridge.

With your pitch deck show the value you’re adding, without making it about yourself. Add in industry data to validate your information.

5. Outline your ideas, THEN your background.

6. Send your contacts (after establishing them- see #2 above) an email asking for a chat about your idea. Have your pitch deck ready. Make sure it’s in a logical order, and succinct. Also make sure you have prepared some small talk based on what you’ve gleaned from your contacts posts and information pages. What groups do they and you belong to? Have that ready to go!

After the chat, and your contact is onboard with you – THEN the ask can come. Ask for the referral, now you have an in-house cheerleader.

What if you’ve worked with someone and lost contact over the years?

Ok, you’ve lost touch with someone. You met / were friends with someone while working and now Need to contact them regarding a job opportunity. What do you start with? “Hello” ?

Don’t over complicate it.

I’m trying to reach certain people I started out my career with, and worked alongside with for years, but that was 33 years ago too.

I did start with “Hello, it’s been a long time.” We picked up conversation like we hadn’t missed a beat, which I find a lot of in broadcasting. I loved working with and for just about every employer in my career.

Luckily, within the first conversation I was able to bring up the job opportunity, and “my person” said they’d be happy to help. You’ll find most people will, as they have or will need a similar recommendation themselves in the future.

Why We Care: PTP Clocks Hierarchy

PTP (Precision Time Protocol) is a protocol used for synchronizing clocks in a network. It is a time synchronization protocol that is designed to provide high-precision time and frequency synchronization for networked devices.

PTP (Precision Time Protocol) is an IEEE 1588 standard protocol that synchronizes real-time clocks of connected nodes in a distributed system using a network. This protocol establishes a leader-follower hierarchy among the nodes (referred to as clocks) where followers synchronize with their leaders, and the leader-follower relationship is determined by a Best Master Clock (BMC) algorithm. Through dynamic relationship determination, the PTP network can simplify the interconnect graph, resolving cycles down to a tree of leaders and followers. The grandmaster, located at the root of the tree, synchronizes with GPS and serves as the ultimate leader for all clocks. Interior nodes in this network are called boundary clocks (BC) and have follower ports and one or more leader ports. PTP can achieve high accuracy, even within sub-microsecond limits on local networks.

PTP works by sending time signals between devices, a best grandmaster, leader, and a follower clocks. The best grandmaster clock sends synchronization messages to leader clocks, and the leader clocks adjust their clock frequency and time to match the best grandmaster clock. The leader clocks send synchronization messages over their network(s), and the follower clocks adjusts their clock frequency and time to match the leader clock. Again, aka boundary clocks. PTP uses precise hardware timestamps to measure the time between devices.

PTP is often used in real-time systems, where accurate timing is essential, such as in audio and video production or industrial automation. It can also be used in some communication networks, such as 5G and industrial Ethernet.

Quick Reference: CDNs

A CDN (Content Delivery Network) is a geographically distributed network of servers that helps deliver content (such as web pages, images, videos, etc.) to users from servers that are geographically closer to them, resulting in faster page load times and better user experience.

A CDN typically works by storing cached copies of a website’s content on multiple servers distributed across different geographic locations, called edge servers. When a user requests content from the website, the CDN automatically redirects the request to the server that is geographically closest to the user, reducing latency and minimizing network congestion. The CDN also helps to distribute network load and protect against Distributed Denial of Service (DDoS) attacks, among other benefits.

Edge servers are a key component of CDN architecture. They are small-scale data centers that are strategically placed in multiple distributed locations around the world, as close to end-users as possible. 

When a user requests content from a website, the nearest edge server to the user intercepts the request and serves the cached content that exists on that edge server itself. If the content is not available, the edge server pulls it from the origin server, caches it locally, and then serves it to the requesting user.

Edge servers are designed to handle high traffic loads and to deliver content with low latency and minimal network congestion. They help improve the performance and reliability of websites by reducing the distance that data needs to travel, and by distributing network load across multiple servers.
