  1. Re:Perhaps on an island subject to hurricanes... on NASA Images of Puerto Rico Reveal How Maria Wiped Out Power On the Island (jalopnik.com) · · Score: 5, Interesting

    Failure rates for underground cables are higher in normal operation, and are more sudden and difficult to repair compared to overhead. You might get it for a residential subdivision, but not for the distribution network.

    The real problem is that the poles are too far apart resulting in dramatically higher wind loading in a direction they have little capability to resist. Coupling that with the complete lack of maintenance, poor quality repairs, extremely high centralization of substation infrastructure, and transmission towers that are likely as under-designed as the island's cell towers, it is pretty easy to see why we are here.

    We were trying to get a redundant feeder to a site there, and it was essentially impossible. Their grid was bare bones to say the least.

  2. Re:Diverted resources to Australia batteries? on Tesla Badly Misses Model 3 Production Goals (wsj.com) · · Score: 2

    Doesn't sound like it; the Australian project is 50% complete and due for full completion in December, and it doesn't seem to require huge engineering or manufacturing resources. Batteries are a minimal concern relative to the total auto production numbers as well-- they delivered 26k cars total.

  3. Re:Ridiculous -- why not enhance the use AIS & on Navy Returns to Compasses and Pencils To Help Avoid Collisions at Sea (nytimes.com) · · Score: 1

    AIS is great on a ship until you end up at Moscow Airport. The fact that the Navy didn't use it in busy shipping lanes previously seems quite stupid, and if their ships have radar absorbing properties it becomes all the more important.

  4. Yes, but accounting is a pretty high risk with a direct attack.

  5. Re:Cost comparison on Britain Opens Its First Subsidy-Free Solar Power Farm (reuters.com) · · Score: 2

    The only challenge is that winter months you get 25% of the output compared to summer with a fixed array (16% with a 2-axis tracker). I would expect winter demand is also significantly higher than summer-- likely at least 50% higher if you aren't using electric heat.

    This makes solar a good part of your power mix-- up to about 10% of winter demand or 50% of summer demand-- but you need other sources. Wind obviously can make a good dent as well-- annual profile is pretty flat and reliable so 50% of a diverse set of sources could possibly work. Both of these would need storage for that level of penetration.

    By my math, that still leaves you with additional needs on a seasonal basis.

    They really needed Lotus Notes though to make it work. IBM wasn't at the right point then, and AmiPro was a good step down from WP.

    No, Corel blew it in 1999. They had Word Perfect and Corel Draw on their distro, and a PC that was low cost and ready to work. They were a year late and a dollar short for what could have been The Year. After that, Outlook became entrenched.

  10. A general contractor would mark up a sub contractor by at least 15% in construction; depending (entirely) what the task rates are, it isn't that bad of a deal.

  11. Wow, that summary sure editorialized. Task Rabbit, from what I can tell, sounds much more like a contractor than a "gig."

  12. Re:One good EMP from DPRK... on Companies Are Once Again Storing Data On Tape, Just in Case (marketwatch.com) · · Score: 3, Insightful

    It is pretty easy to protect cold tape from an EMP, even if it is at a close range.

    The problem is that Tape really isn't any more secure than anything else-- just modifying the tape drive firmware could easily corrupt data. With a little extra work it could encrypt the data and allow DR simulations to run as long as the event horizon hasn't been reached.

  13. Re:BAD Project Management kills everything on Is Project Management Killing Good Products, Teams and Software? (techbeacon.com) · · Score: 1

    The technical coder is effectively a project manager in your example-- the problem isn't that developers can't coordinate among themselves, but rather that it becomes less efficient as project complexity increases. If you have a team of superstars you can pull it off, but you are stuck finding superstars for each position. There are places for B-Team players on most projects.

  14. Why do you think they can't mitigate well crafted large scale attacks? Some of the things they do only balance the asymmetry of an attack, so that the resources used on the remote machine is comparable to the resources required on the host.

    I am honestly curious what happens when average residential connections are gigabit, but I am sure they are planning for that.

  15. Re:Product Development isn't mathematical. on Is Project Management Killing Good Products, Teams and Software? (techbeacon.com) · · Score: 1

    It is easy to think that way, but you miss out on many of the benefits of a good project manager. A good PM isolates the team from the politics, manages the scope, and tracks financials-- things programmers and engineers generally hate.

    Software really isn't that different from any other creative field in terms of trying to benchmark in real time. It can be done, but with a lot of caveats, disclaimers, and SWAG. Project managers understand that enough to control the process.

    Working with bad project managers is miserable though. Two hour daily conference calls for something that isn't going to change for three weeks... over Christmas... I can think of one PM I will never work with again.

  16. BAD Project Management kills everything on Is Project Management Killing Good Products, Teams and Software? (techbeacon.com) · · Score: 3, Interesting

    On anything with more than 5-6 people on a team, a project manager is a necessity. It is inefficient in first-order terms, but keeping people focused on what they are good at (and a dedicated person managing scope) dramatically improves productivity. Generally, less than 10% of hours should be in project management.

    Bad project management is a different beast. Bad project managers add needless complexity, waste time, and draw focus to aspects of the project that participants cannot control.

    This kind of population has always existed; many people don't really have enough money saved to retire, especially when they are concerned about things like long term care costs at the end of life.

    A little extra income for a season can make a big difference.

  19. That is traditionally how the cycle works, and my experience today in hiring engineers (EE/ME/ARCE).

    When the job market improves, more people consider changing jobs, which makes it easier to hire people with experience. When it is weak, you get a lot of marginal applicants. Somewhere in the middle, your best investment is in training inexperienced people.

  20. Be careful. Your line of thinking is how real-estate bubbles grow and pop. There really aren't any safe investments today that even outpace inflation long term.

    The best strategy is diversification and living below your means while the going is good.

    From what little I know of T-Mobile's operations side, I think they are well ahead of Sprint for long-term planning and have a much better/leaner operational model. The value of Sprint is almost entirely in their subscriber base, and T-mobile would be paying a premium for them through a merger.

    Sprint used to have a lot of their own fiber, which could be a value for smaller regions or POPs, but again it is limited.

    While I would prefer four viable competitors, that doesn't appear to be viable much longer. Bankruptcy seems the better strategy for the market.
