  • Nice info! A few notes:

    Volts are not energy. Volts are a component of electrical energy. The drop in voltage is because of the additional load on the circuit that the charger represents. Energy losses come out as heat. If something gets hot while it’s doing its job and its job is not to heat things it means that it’s got a loss of energy somewhere. I’d bet that the charger warms up in use, and the loss is likely greater than the 1.75% loss that you were thinking you had with the voltage sag.

    L1 charging is less efficient for a few reasons, but the biggest increase you get in efficiency from the L2+ charges is time. Triple the charge rate gets you full in an afternoon rather than overnight. But then you can parlay that into cost savings by timing your charge to off-peak times and charge up on cheaper electricity, if it is available in your area.

    Electric cars do have an easily measurable range drop in cold weather for the reasons you outlined. Gas cars really shine in cold weather because not only do they not perform measurable worse in terms of range when the thermometer drips, but they also make their own heat, ALL THE TIME. In electric cars you have to use battery power to heat both the battery and the cabin, which is yet another drain on range. But, that gas combustion heat is loss in the summer when you’re not using it. Like the waste from your charger, but this time it also comes with emissions.





  • Only if he shows me that he wasn’t destroying the company, but building networks to leverage crises into profit.

    Which, it would seem, is what he and the rest of the C-suite team did.

    They bought out the old owners and signed up a bunch of new customers that we didn’t understand how to work with (new industries with different requirements, we were very specialized toward a few professions and our staff’s knowledge and skills reflected that). They also brought in fresh, inexperienced people to manage the clients, so we didn’t really get very good on-boarding results and didn’t generate good documentation for the help desk to work off of. Right off the bat we did a bad job for these new customers and it took us a long time to do it, while our long-time customers had their wait times go up by an unacceptable amount.

    My team was running at their limits, but I was not allowed to let up at all because we needed to get the tickets down. 9 hours days were the minimum, 9.5-10 were the norm. We hadn’t hired any new people when we added the new clients and the new clients generated tickets at 1.75x the of rate existing clients, and they were still signed up more. After months of begging, they hired two people for Tier-3 positions without testing them technically. They were both from corp call centers and had previously read scripts with troubleshooting steps on them. Neither had ever logged into a router. This is where I quit.

    Within four months of my departure (and a few others at my level around the same time, we had all had enough) the company had lost 30% of their clients, two of which were huge 250-person entities that were cash cows for biling. Four months later the owner-operators sold the whole thing to another company, getting high level jobs, equity and cash out of it. As far as I know they’re all still working for the bigger company. Even if they lost money buying and selling, chances are they’re on top in the long run.










  • Ditto. 7800X3D is a beast for games and I don’t give half a shit about productivity performance on my gaming machine. I got mine for around $350 early this year and I’m absolutely floored that it’s now over $400. That’s not the direction things are supposed to go.

    I think we may be in the last generations of x86’s desktop and laptop dominance. All phones and now all Macs run on ARM-based chips and they do just fine while sipping watts, compared to x86’s two big proponents both having faltering launches on their latest generations with ever higher TDPs where you only get more processing power by using more electrical power.
