Make your Van bought Speakers Not Suck

Coming soon, the project to bring your van bought speakers to mid-fi excellence. 

In light of Spectre the performance debate on HyperThreading is solved. Turn off Hyper Threading to help fix Spectre and mitigate Spectre-fix performance issues

There has been a relatively longstanding debate between various gamers and overclockers about the performance of modern intel HyperThreading (HT).  One group has suggested that turning off hyperthreading improves performance in gaming and results in lower temperatures and voltage thus allowing higher overclocks.  The pro  HT group points out the modest improvement in highly threaded workloads.

However, in light of Spectre its time to shut down HyperThreading from your bios.

Spectre attacks HT branch prediction, so you can either use Spectre fixes which will hurt the theoretical improvements of HT, or you can shut off HT and go for slightly higher overclocks or perhaps lower your voltage a bit to improve long term reliability of your chip and get better stability.

Today after much research I pulled the plug on hyperthreading, especially with the new higher core count processors, it really does not make a performance increase in most daily situations aside from perhaps CPU video encoding which should be done on a GPU if possible anyway.

So I recommend to everyone in light of spectre shut down hyperthreading, no matter what the official "marketing speak" from Intel suggests about fixes and how hyperthreading isn't terrible.  (I would still implement any spectre fixes though)

Brief LCD TV Buyers Guide

In my opinion no tv is perfect the trick is getting a good compromise for the space.  That being said here is my overview after owning (too many) TVs:

1) Size matters most.  Get the biggest size you can afford up to a point.  Be careful with panels above 70" or so, they can have issues with backlight uniformity and LCD Panels.

2) Backlight uniformity is very important,  perhaps one of the most under-rated issues with TVs.  So get a TV with the best back light uniformity possible.  Some of the older "thick" LCDs are very good at this. Very little is distracting to the experience as having lighting affects that are unusual and notable.

3) 3D, HDR and 4k:
a) 3D blu-rays are still available, and many major theatrical releases are still in 3D.  Most TVs are not able to deliver 1080p 3D passively, though some late LGs do.

b) 4k is very welcome on big format LCD and projectors or screens that you sit close to.  The close dot pitch of the screens will make it look brighter and clearer even if you are not watching 4k content.

4k content is subtle but noticable when A/B tested against similar content (4k Blu-Ray vs Blu-Ray).  The effect is clearer, more color, more lifelike images.  It is not as noticable as the jump from SD to HD.

c) HDR is noticeable but not everyone loves it.  It makes the directors vision more directly visible at home.

d) 120hz processing.  120Hz or 144Hz native screens are rare but a sign of a quality set.  Good 120Hz processing will often be labeled as "240 or 480" etc.  Very few sets will display 4k at 120hz interpolation and some early 1.4a HDMI sets are limited to 4k 30hz which may be good enough for watching movies if it is flexible.

Having a 120hz or 240hz set helps out with watching 24 or 48hz content, and sports.  It can also help with streaming.  Not everyone likes it but I believe having smoothing on helps content if indeed it is of high quality for example Sony or Samsung.

4) Curved screens feel natural and help with off axis viewing.  It seems to me our vision process the world in somewhat curved realities.   A curved screen helps when you have several viewing positions that are off axis and also when viewing the screen straight on by enhancing the illusion.

5) Smart tech.  I would not buy a TV or not buy a TV for Smart features.  Roku boxes are almost always faster and more seamless. And while rare it may be possible for their to be vulnerabilities in TV Smart code.  I wouldn't even hook up your TV to the internet if it is a Vizio as they put out updates that can hurt TV performance (check out 80" M series circa 2013)

6) Exotic technologies such as OLED. Organic LED are very nice, they have some issues with blacks and need a lot of information to display properly.  They can deteriorate so I would estimate usable life at 5-7 years.   Looking at OLED PS Vita vs LCD Vita it is clear the OLED has beautiful colors that are deeper and more vibrant than regular LCD.  OLED is more sustabtible to sunlight and direct sunlight.

It has been posited that OLED should be broken in on low back light settings and kept out of sunlight.

I would put curved TVs toward the end of the enhancements of the TV.  If you can get a nice 70" for the same price it I would tend to buy it over a 65" curved.

Reset Netgear Routers That Won't Reset -- Get Back to Factory Default Password

There are various methods suggested in manuals and on the internet to reset stubborn Netgear Routers.  Sometimes these methods do not work.  I will go through the three methods I know of and start with the most effective to least effective, which should likely be executed in reverse order.

  1. Hold the reset button in for 1 minute while the unit is plugged in.  This is what I believe to be the most effective method and has helped me reset a stubborn R7000. 
  2. Hold the reset button for 30 seconds and then unplug (while depressing the reset button) for thirty seconds then plug in router and continue to hold the reset button for an additional 30 seconds.  I have heard this method may not work with the newer Netgear routers such as the R7000P, R8000 etc. 
  3. Hold the reset button for 8 seconds.  This is the first option to take and should reset most routers.

Are Rolex Spring Bars Different? How Much do Gold Rolex Springbars Cost? How do you buy Rolex Springbars?

Are Rolex Springbars Different than Aftermarket?

YES! Using the same procedure above, go to the AD, buy the correct springbar for your watch.  Rolex springbars are different and they can change the fit, for example some presidential bracelets may slightly pop off with aftermarket.  Gold Rolex watches come with solid gold springbars which help not eat into the watch case or clasp.  

How Much do Gold Rolex Springbars cost? 

Small Gold springbars are approximately $60 each and long ones are approximately $100-120.


One of the springbars will be shouldered, that goes on the non-adjustable end of the clasp.  The other will have no shoulders, that goes on the adjustable side of the clasp.  While both may fit initially removing the springbars in the future will be much more difficult if installed incorrectly.

How to remove a tight springbar:

Do not just push on one side of the springbar with a small tool. Try to push on the whole springbar with a flat surface then pull from the other side from the "fat" surface of the springbar.  

The idea being that you do not want to put too much stress on the sprung portion of the springbar so for example push on the "stationary" parts of the springbar, or the whole springbar together.
