Information Security Considerations for Investors pt.1

This is some general notes and a suggested checklist on Information Security and Privacy as they relate to financial information you as an investor, should consider. It came from a general discussion between investors about “How much of your financial information do you allow on the cloud”

TL;DR

  • Require 2FA on your Bank and eMail accounts
  • Use a Password Manager tool, follow the recommendations

Background. 
Data that is truly secure is data that is inaccessible to anyone, you included. The internet is all about accessing information easily.  You may notice these things are opposites.

You can of course go far more extreme and attempt to keep your finances offline entirely, this is however exchanging one set of risks for another. 

Your financial information is stored in many places. Keeping that information private is an exercise in risk management, not risk elimination.

Your information is not totally private today. Large retail conglomerates already know much about you and track you between their stores. 


Who has copies of at least some of your financial records / behaviors today –

  • Retailers – anywhere you shop
  • Bank / Credit Card companies
  • Govt Tax Office
  • Employer
  • Brokers / Agents / Where-ever they store their data and backups
  • Accountants / Lawyers / Where-ever they store their data and backups
  • Lands Offices / Local Government
  • Property Information Companies
  • Utilities – Water, Electricity, Council etc.
  • Loyalty cards / Frequent Flyer programs
  • Google / Facebook
  • Financial aggregators

This is mostly thinking about how to 
a) Keep your financial accounts from being misused
b) Keep some information moderately confidential. 

This is not about identity theft, which is a larger more complex topic. 


Financial Account Access

If it is important – then a password alone is insufficient protection. 
You MUST have 2FA (Two Factor Authentication) on these accounts at a minimum. 

  • Banking / Brokerage
  • email address used for Banking or Banking Recovery
  • Google or Apple account for your Phone
  • Cloud storage used for financial records / data
  • Password Manager – Lastpass, Onepass etc.

Many products rely on your primary email address to contact you for password resets. This means if your mailbox is compromised, someone could reset your financial passwords. This is why 2FA is needed on the email account you use for this function. 

The problem with 2FA is it works. Recovery from losing your token can be difficult or even impossible. Sorry, security nearly always makes things harder for everyone, attackers and users. 

I would recommend planning for account recovery before you need it. It’s much more difficult after things have gone wrong. This will also show you where you might have weaknesses.

This space is relatively new and still developing. 
If you have no choice other than a password, follow these rules

  • Use a random password generator w/ >16 characters
  • Use a password manager tool
  • Use a separate password for each application / website

If you have an option to turn on alerts for transactions / logins, so you get and SMS or email, this can help to reduce fraud. 
Consider all places where you have things of financial value or credit stored, including Frequent Flyer accounts, Superannuation etc. 

Stored Data

Nothing can be kept entirely confidential.If it’s connected to any network, at any time, it is at risk. 

I do not consider “the cloud” to be of significantly different overall risk than any other data. Whilst some risk areas are increased, others are decreased, resulting in a net overall equal or potentially reduced net risk. 

The largest risk driver I see today is not location of storage, but ease of connectivity. If data is more accessible to you, then it is likely more accessible to bad guys. If you take lots of backups to prevent data loss, those extra copies increase the likely hood of someone accessing your information. 
If you do the following steps, you will reduce your overall net risk. Every action you take introduces potential new risks, the trick is to reduce overall exposure. 
You should – 

  • PC / Mac
    • Run the Latest Operating System, All patches and Updates. Don’t be cheap here. 
    • 3rd Party Anti-malware / security tools are not recommended – stick with the builtin tools from your OS vendor. 
    • Encrypt your Backups. Be careful where you store the key.
    • Encrypt your Computer. Be careful where you store the key.
    • Be careful with storing data on USB disks
  • Cloud storage is generally as secure as the account used to access it
    • Use 2FA and strong passwords
    • Use a separate password for every website
    • Use a password manager tool
    • Use well known providers and stay aware of risks
    • Read up on the vendors security options
  • Phone / Tablet devices are often quite secure from factory. For average users, Apple devices tend to be more secure than Android. 
    • Enable find my device
    • Enable backups

FYI – Bio-metrics are surprisingly insecure. They are not secret (eg. You leave your fingerprints everywhere. They cannot be changed when stolen (well, you will run out of fingers to cut off after 9). They work well only in very specific circumstances. Do not consider bio-metrics a replacement for passwords.
The reason bio-metrics are effective with your phone, is that the device is the second (2) factor authenicator. You cannot use your fingerprint with Apple, only with that device.

2014 Specialized Brain to 120mm?

Question – Rockshox SID B (2014) has travel from 80, 100 and 120mm. My Epic with Specialized Brain is 100mm. Can I upgrade this to 120mm?

IMG_7095.jpg

Short answer – No

Long answer – No, the Brain Cartridge connects the fork Upper and Lower sections and has 112mm of travel at best and really only 107mm usable.

If you get rid of the Brain damper and buy the parts to convert it to an RL, RLT or RCT3 damper, the the uppers and lowers are seperate.

Also – if you are wondering how to disassemble your lowers, you need a 10mm box wrench. No shortcuts.

Philips Hue vs Philips Wake Up Light

Philips leads many areas of lighting, and I appreciate a business that knows to specialise and do well in their chosen area.

I have been using a Philips 3520 Wake Up Light for over a year now. I find it very gently wakes me up, especially in winter, and suits my rhythms well. I hate sudden loud alarm clocks and this solves that problem well.

I recently bought a clever Philips Hue kit to play with and compare.

Both are high efficiency LED based units with some clever tricks. This should give you some comparison information.

Philips3520 vs Hue

 

Feature Wake Up  Hue 
Power Outage Behaviour Forgets Time – No Battery Backup Turns on Full Brightness.

It is VERY annoying to have lights turn on in the middle of the night after a power outage leaving you fumbling for your phone to turn them off.

Does not forget time or schedule with power interruptions.

Gentle Wake Up 40 Minutes, very gentle and pleasant. 9 Minutes with harsh sudden start at about 30% brightness
Colours Fixed Huge variety
Programming None All sorts of clever options, especially with IFTTT
Style Light comes from 80% from front of unit. Use any fitting you like
Alarm (Sound) Function I never use it None
Reading Light Very good.

Small fiddly buttons.

Unfortunately easy to disable alarm by accident.

Very Good. You need your phone handy.
Power 24V DC 220V AC
Comments Light from the rear of the unit bounced off the wall would be much more gentle on the eyes.

It really needs a battery backup. I have actually hacked a 24V battery into mine to be sure it works no matter what.

Powering on to full brightness after a short power outage at 2AM is very unpleasant.

The harsh startup is also a bit rough. I’m sure both of these could be fixed in software.

If Philips merges these two products, they could be onto a really good thing. Some usability bugs could be readily improved.

Oh – and a good battery backup.

 

 

 

 

 

SSD Sadness (and the Cloud to the rescue)

My first SSD, a 60Gb OCZ Vertex II ceased to be last week. I didn’t take “no moving parts” to mean “no pulse”. This wasn’t the vague threat of “SSD wearing” – but simple undetectable dead drive.

Luckily, I sync most of my data to the cloud, so the interruption was inconvenient, but not catastrophic.

SSD’s – great new tools, but they still fail. I mustn’t get complacent.

Unfortunately everything on my desktop was gone. The most commonly used “workspace” – but it doesn’t sync readily to the cloud. There goes quite a few hours work. I’ve since made a simple script to copy the desktop to the cloud folder each night – at least that will reduce the future impact to just a day’s work.

It did certainly get me to thinking though. A free consumer cloud service just saved my bacon (as I always hoped it would). How many of my customers are using this? It complies with no corporate standard, but offers so much value. And I have nothing that can compare or compete. Sure, I could buy some products, and run my own PC backup service. I doubt it would compare for features or functionality.

So, again we have the balance between great user experience, and poor corporate compliance.

I firmly believe the user experience wins in the long run. This has been proven time and again. PC’s proved it over IBM. Windows over Novell. Apple is busy proving it again.

So how is an IT team to meet yesterdays compliance requirements in tomorrows user driven world?

Easy Trailer Review

I needed a trailer to replace my XF falcon ute. To be flexible enough to replace the ute, I wanted a flatbed with removable sides. That would let me carry longer loads, larger loads, and store it where I wanted. I did not want a box trailer – too many limitations for my needs.

P5010017

I own a large heavy car trailer, so this was to be light and simple instead. Up to the legal un-braked limit of 750kg. As I am legally limited to this weight, it made sense for the trailer to be as light as possible. This would leave more room for payload. Making it extra heavy duty wouldn’t let me carry any more load. I wasn’t planning on using it off-road.

The flat bed with sides would let me use it in more ways. I also wanted to store it winched up to the roof of my carport, over my cars. This would get it out of the way when not needed and keep it out of the weather.

Shopping around at various trailer manufacturers offered almost nothing in the way of flat trailers with removable sides. Several quotes where well over $2000. I considered making my own using an alloy ute drop-side tray, but the cost was still up there. Several manufacturers actively laughed at me when I said I didn’t want a  “heavy duty” trailer. I laughed at them when they said their trailers weighed 200+kg, leaving less for payload.

Then I came across Easy Trailer. A company that gave me lots of options, made a lightweight trailers, and encouraged their customers to customise their trailers. They order over the web and deliver to you.

They specialise in folding trailers, but for me that wasn’t a critical feature. Mine would be stored on the roof, not folded against a wall.

What I wanted would cost me about $1000 from them, and about $400 in extra bits. With rego that’s under $1500, not bad.

Options

I selected a 8ft x 4ft trailer that could tip as well. I added a spare tyre and tie down loops. I recommend 8 tie down loops.

The floors have an option of steel or ply. Aluminium is not an option. Plywood is very good as it gives a “softer” surface that won’t damage what you are carrying. I had 5mm alloy checkerplate at home, so didn’t need a floor supplied.

The sides are the optional heavy duty sides. The front and rear gates double as loading ramps for anything you want to roll onto the trailer. They can come open or with a steel skin. No aluminium option.
Again, for weight and corrosion reasons, I went with 2mm aluminium from a local supplier.

The jockey wheel they have as an option didn’t do what I wanted, so I grabbed a lightweight folding one locally from Repco.

Electrical

The lights supplied are conventional bulb types – that means unreliable. I threw them in the bin and bought better sealed LED lights from eBay. Lights on trailers are a constant source of problems and I hate chasing dodgy light peroblems on my trailers.

To mount them properly, the LED lights I used do need a small backing plate made up to cover the rear. 1.6mm alloy is fine for this. You’ll also probably have to move the number plate and get a light for it. Whilst most conventional lights have a number plate light built in, this is uncommon for LED lights.

As far as I could find, on this size trailer, clearance lights are not required. Despite this, I fitted a set of low profile LED clearance lights to replace the clearance lights supplied with the trailer.

The wiring supplied uses the trailer as an earth – a likely problem spot. As such I used some of my own wire to run a full earth, ensuring all connections where sealed. I don’t solder vehicle connections anymore, finding a soldered connection less reliable than a well sealed crimped connection. The heat causes more fatigue on the wire and corrosion seems to get into the wire further.

Assembly

The trailer comes in lots of bits, with a lot of bolts. Plan on 4-6 hours to assemble it for a first time user. It’s easy enough, just a little tedious.

My assembly tips would be

a) Watch the direction of the C channels, it matters

b) Don’t fit the brackets for the timber stakes, you’ll just have to remove them later.

c) The tie downs replace bolts, figure out which ones as you assemble to save re-doing it.

d) Consider fitting nutserts / captive nuts to hold the sides on. Much less tedious than nuts and bolts.

Review

The trailers are imported from Taiwan, and in some ways it shows in the quality. They are obviously sold worldwide, as I saw one used on the tyre throwing rig on episode 80 of  mythbusters.

The powdercoat finish is ok, but the corners are sharp and will rust there where the coat is thin. I personally wouldn’t leave it out in the weather for too many years, but I say that about any trailer that isn’t hot gal dipped.

The frame is folded U channel steel, bolted together. This gives some flex that should relieve some point strain issues. Unlike a welded trailer, it is unlikely to crack from fatigue. The nuts are all nylocks, so it shouldn’t rattle apart too easily, although it would pay to check the bolts every so often.

The axle is folded steel, not solid bar. It would not stand overloading well. The drawbar is also C channel, so I wouldn’t overload it.

The compliance plate on mine was for 500KG. I spoke to Easy Trailer and they sent me another one for 707kg, the advertised max weight. The design is clearly for a distributed load, so if you are planning on carting large rocks or engines, be careful where you load them.

The wheels are 12” cross ply tubeless tyres on cheap steel rims. This is good for me as they keep the trailer low to the ground and keep the overall weight down. Cross ply tyres have a much heavier load rating, – these are a small narrow tyre.  The studs on the hubs weren’t drilled particularly square, my only complaint. Some people worry about small tyres at highway speeds. Mini’s work just fin on 10″ wheels at much higher speeds than this trailer will ever see. A wheel bearing’s RPM has nothing on a tailshaft.

I added an extra brace for the spare wheel to stop it twisting when stood on. I also added a swing up jockey wheel and extra tie down points. I tend to modify my stuff though.

The assembled trailer with sides on weighs in at just over 100kg, leaving 600kg of payload.

I have used it to transport my 200kg motorcycle, mates bikes, mulch, cane mulch bales, timber and other random items so far. I would not overload it badly. I would not take it over 1000km of corrugations and expect it to survive.

I like it, I love the lightweight design, I like the suppliers attitude to customising it, and I like the price. It tows well and is very flexible.  It’s unfortunately invisible behind the Landcruiser, I’ll need a reversing camera to see the thing.

An LED Birthday for all my Maglites

P5010019

I love my Maglites. I know technically there may be better out there, but they have such a nice solid feel to them as you thump them over someone’s ….. err, well, anyway.

Whilst they are good quality, they very old tech, so a swap to LED’s was in order. LED’s offer greater output, 5 – 10x battery life, and are much more shock proof.

The debate as to “which bulb is best” goes on endlessly, so I settled for those that I could source from eBay and post to Australia.

The direct bulb shaped replacements are very rare in high output versions. Most inserts offer an unusual shaped fitting and often a different reflector.Standard shaped bulbs often can’t dissipate enough heat to keep an LED cool. LED’s hate heat for effective output. Some LED’s will start out quite bright when turned on, then dim somewhat as they heat up.

The Maglite brand LED replacement bulbs are nothing special according to most reviews, and I wanted something with some more power.

Manufacturers appear to have come and gone, so don’t be surprised if the bulb you want is no longer around.

One downside with many inserts is you lose the focussing ability. In some cases they are do much brighter it doesn’t matter.

Terralux has a good range of inserts, with a balance of cost, features, output and availability. They are readily available on eBay US.

Candlepower Forums has in depth discussion and reviews, detailed comparisons etc. As the space changes so quickly, many of these are out of date.

Regardless of which bulb you choose, it should by preference be regulated. This keeps a constant brightness and gets best possible use out of the batteries. You don’t need to throw them away until they are fully used up, and lose very little brightness as they discharge.

Alkaline batteries have limits on how much power you can pull out of them. Essentially, if the bulb you choose will flatten the batteries in under 10 hours, the battery won’t give it’s full rated output.

When I started this I was going to do lumen comparisons and shots of beam patters, but honestly, it changes so fast, and others have done this already. I figured I would just put down my experience and you can pick bulbs on your own.

Maglite 4D CellTLE-300M-EX
The brightest insert I could buy, with 3 x 2w elements. It’s not focusable, but so bright, it doesn’t matter. 3 brightness levels. The three elements produce a consistent beam pattern. 700 Lumens. About $70

All the other bulbs have been discontinued already.

An eBay search shows most bulbs are around 100 – 300 lumens and about US$20ish.

They are all an upgrade. Every brand and model seems to differ in it’s focussing.

Factors I would consider are

  1. Price
  2. Lumens Output
  3. Focus – ability
  4. Regulator

Not pictured is my Maglite solitaire, it was upgraded with one of these.

Yes, that is an active device, there is a regulator in the round disk.

For about $150 all up, it was well worth doing the six lights.

Media Centre – New Hardware

I rebuilt the media centre recently, as the AMD was only a temporary stand in. It was using far too much power compared to the old mobile CPU.

The new i3 is perfect for this. Enough CPU grunt to ditch the 3rd party video card power hog, everything on board. I’m an energy saving nut, so this is the lowest power system I could put together.

Finally – Reliable Cordless Phones and VOIP on Naked ADSL

When I changed over to Naked ADSL2+ with Internode, I had to sort out a replacement for the home phone. It was a tough journey and about 12mths of problems before I found a reliable combination of devices.

The problems ranged from

  1. Failure to ring
  2. Low Volume
  3. Dropped calls mid call
  4. One way voice
  5. Poor call quality

After 12 mths of drama’s I found only Panasonic DECT handsets where reliable with the VOIP solutions.
I also found that running a “single box” solution is less hassles than “multiple box” solutions.
DECT has a much greater cordless range than most other handsets.

Here are the combinations I tried and the issues associated.

Routers

Netgear WNDR5500 + Netgear DM111p + Open Networks 812L VOIP

  1. Rubbish combination, awful reliability, even after warranty replacement.
  2. VERY unreliable, mostly due to router
  3. Telstra DECT and Uniden WDECT = heaps of problems as well
  4. My WNDR3300 review here

image image image

Netgear DG834G v3 + Open Networks 812L VOIP

  1. Very reliable, very stable, but limited features
  2. Reliable with fixed handset
  3. Unreliable VOIP with Telstra DECT and Uniden WDECT Handsets

image image

Billion 7404VNPX

  1. Single box resolves interop issues on volume and ringing
  2. Took a few firmware versions to improve reliability
  3. Still needs rebooting for DHCP reliability
  4. Fast
  5. First unit was buggy, replaced under warranty
  6. Reliable calls only with Panasonic handsets
  7. Billion recommends only using fixed handsets, not cordless (from their support line and whirlpool)

image

Cordless Phone Handsets

I prefer to use 1.8GHz DECT handsets where possible, they have MUCH (2x-10x)greater range than 802.11, and don’t use the same 2.4GHz wireless spectrum. 5.8GHz has worse range than 2.4Ghz or 1.8Ghz. Higher frequency = less range.

There seems to be some issues with call stability and cordless handsets. I can only guess from all my testing that it relates to off-hook detection. I played with every setting under the sun, and nothing helped. 12mths of stuffing round to find that Panasonic handsets work well.

  1. Telstra Touchfone T200
    Fixed handset – works well in all circumstances, if the router allows the call in.

  2. Telstra DECT Cordless – Poor quality and hang up problems, poor call quality and cheap handsets.
  3. Uniden WDECT – LOTS of problems with VOIP, don’t bother. AWFUL.
    The problems are twofold. Radio interference is a nightmare, even when seperated by 10+M
    The on/off hook sensing of the router and the base station appear incompatible, hanging up on calls all the time.

Dorcy LED Torch

Cheapest LED Bulb

Here’s a great hack. KMart is selling these torches for about $3.50 with batteries. The LED in this is fitted to a normal sized bulb fitting, meaning it can be taken out and put directly into any 2 Cell torch, AA, C or D.

P4090002

http://www.dorcy.com/products.aspx?p=412503

It’s a very bright 10mm LED in a normal bulb fitting. No regulator circuitry.

This has to be the cheapest source of LED drop in bulbs for torches I have found. Or you could just use the torch.

The beam is much brighter than a normal 2 cell torch. Runtime would be significant, although I haven’t done a full runtime test. You’ll use far less batteries, better for the environment.

Beam pattern is an average spread.

The "Works Every Time" method for car Automotive Driving Light wiring.

image

I frequently see wiring diagrams for Driving Lights that just don’t work in many cars.

Toyota nearly always and Nissan often use a what is known as “switched earth” wiring for their headlights. They do this so that each headlight can have it’s own 12v supply and fuse, meaning in the event of a problem, you only lose one light.

In a switched earth headlight, assuming you are using a H4 bulb with 3 pins (very common) the power is switched twice. +12V is fed through a relay or switch to the common pin, and then either one of the other pins (one for High, one for Low) is alternately connected to ground through another relay or switch. If you go looking for +12V to power your driving lights or their relay in this system, you wont find it easily.

A far easier method is to always wire the trigger for your relay ACROSS the high beam bulb circuit, instead of from +12v to ground. This means that regardless of the vehicle wiring, positive or negative switched, the driving light wiring is the same.

There are several other benefits to wiring in this manner.

a) It works with either positive of negative switched headlights

b) It avoids problems with the relay not dropping out. The high beam indicator inside the car can trickle enough power through to not let the driving lights drop out. It takes about 8-9V to trigger a 12V relay, but only about 4V to hold it in.

c) It avoids problems with the relay not dropping out due to a poor contact on the headlight connection. This common fault can setup a circuit through the other filaments and cause enough voltage to be present on the high beam filament to hold the relay open. This voltage is far less across the filament than in relation to ground.

image

image

So how do you wire it?

It’s easy really. I have gone with text, as many people have trouble with electrical diagrams.

Power CCT (Heavy wire)
Battery – Fuse – Relay (Pin 87) – Relay (Pin 30) – Driving Lights – Chassis (Ground)

Switch CCT (Light wire)
Headlight Common Pin – Switch – Relay (Pin 85) – Relay (Pin 86) – Headlight High Beam Pin

Simply tap into the headlight wires / pins with vampire taps.

Presto – I guarantee it will work.

If you don’t have H4 bulbs, even easier, simply go straight across your high beam bulb wires for the trigger.

What was Microsoft smoking when building their QoS stack?

 

QoS is somewhat of a confusing area. The most common method of marking packets at Layer 3 (IP) is with a DSCP tag. This method replaces the earlier Type Of Service (TOS) tag, and uses the same space in the IP header.

Whilst DSCP has a far greater range of values than TOS, there are some that are commonly used in most implementations. DSCP values also overlap with TOS values.  There is a table showing the relationship between DSCP and TOS here. This is all likely to lead to confusion in implementation.  

Whenever talking about this stuff, there is one very common area of confusion. Numbers. That is, whenever a number is given, is it in Decimal, Hex, or a “type” number. It can also be given as a full byte (non-offset) value – -effecting it further. The DSCP table linked above helps show the different ways a single value can be represented.

eg. 34 = 0x22 = AF41

Be VERY sure you know what they are using in any document you read. The vendors switch between the values in their own documents with remarable dexterity and no explanation.

So – back to Microsoft’s weirdness.

VOIP traffic is generally tagged as “EF” (Express Forward), one of the highest priority values. Microsoft chooses however to use DSCP marking of “CS5”. That would make sense if they where tagging using TOS, as that matches the common practice for TOS values. BUT, their own documents state they are using DiffServ which is based on DSCP markings. DSCP recommends EF for voice, not CS5.

In short, it looks like they have mixed up the older TOS standard with the newer Diffserv standard, and gotten confused along the way. This causes problems with the mappings not classifying correctly if you are using vendor managed L2 prioritisation such as Telstra’s IPWAN DCOS services on their MPLS networks.

This behaviour is consistent across:

LCS 2005
OCS 2008 R2
Server 2003
XP
Vista
W7

The only take away I can get is that Microsoft does not recommend the use of QoS in general, and offers that OCS using RTAudio codecs does not require or recommend the use of QoS due to the protocols in use. I have found however that on services that suffer from congestion, it helps improve the quality of the service.

Versys KLE650 vs VStrom DL650

Review from someone that has owned both.

image image

Summary

Despite very similar specs, these are two very different bikes.

Versys is more “fun” to ride round town, but not so comfortable on longer rides in stock form.

VStrom is better to customise and tour on. it has ABS.

 

VStrom Versys
Vague Steering (until modified)

Falls into corners like cruiser

Smooth motor @ cruise

Vibey motor @ high revs

Motor torque has OK pull

Won’t wheelie

Limited tyre feel

Good seat U shape

Great dash

Dull brakes

ABS available for only $500

Limited leg room

Lots of Acc’s available

Long front guard

Great headlights

Weight more on rear wheel

Long, very long wheelbase

Brilliant 350-400km fuel range

Sharp at low speed

Tips in like sports bike

Vibey @ cruise

Smooth at high revs

Motor Pulls like a train

Wheelies (lots)

Harsh suspension, ok feel 

Seat tips forward

Lousy minimalist dash

Sharp brake feel

No ABS in Australia

Good leg room

Limited accessories

Front guard too short

Headlight average

Neutral weight balance

Short wheelbase

Average 300km fuel range

The Versys had Michelin Pilot Road 2 tyres – wonderfully sticky. Despite having very similar dyno charts, the Versys definitely feels more torquey and pulls much more when over 160km/hr. The Versys suspension is far to harsh on less than perfect roads, even after tuning it as far as I could. I find this a major failing on a bike sold for it’s long travel suspension.

The VStrom tyre choice on road is not as sticky, but has a better range of off-road tyres.
The VStrom with Racetech fork valves and springs is a much better beast than stock, with steering sharpening up, and brake dive disappearing. Before it was a bit soft and somewhat harsh.

Drag racing them side by side shows the acceleration from 1st to 6th is basically exactly the same. Seat of the pants though feels like the Versys is MUCH snappier. Ass Dyno wrong again.

Braking is interesting. The ABS gives the VStrom an unfair advantage. I have tested the ABS in both wet and dry conditions finding it reliable in both. It tested at 1.05g using Dynolicious on the iPhone, vs only 0.82g for the Versys.

I am replacing my Versys with a VStrom, as I prefer the range of parts available, ABS and the different feel especially on the highway. The Versys is more fun to ride round town, if you can ignore the issues.

Great new CFL Downlight

When I renovated the house I installed a heap (18) CFL downlights in the ceiling which I reviewed. These 15W reflector CFL’s warm up fast(ish) and provide good light.

I was never happy with the kitchen bench though – it wasn’t bright enough. I recently bought a light meter from eBay and confirmed my suspicions. 60 Lumens at the bench top whereas kitchens are recommended to be around 150 lumens.

Surprisingly under my range-hood with it’s pair of (yuck) 20w G4 halogens scored 140 lumens.

I tried replacement bulbs in the downlights to get additional brightness with no success. The 18W Philips reflector is larger and does just fit. It’s only available in Warm White which made it seem no brighter and not match the rest of the house. I tried a larger 23W Par 38 spotlight, but it doesn’t fit into the housing, and is too large and heavy.

I thought I might need more spotlights on the wall until I made a new discovery.

http://www.pierlite.com.au/au/3091/dot-110 is a silvered reflective downlight housing that takes a normal ES bulb. By putting the silvered reflector in the housing, rather than the bulb, means you can use a normal bulb without losing all the light.

It comes with a Philips 20W ES Warm White bulb. I tried both a Philips 23W Daylight and 23W Warm White, much preferring the Warm White.

I’m impressed – this thing is BRIGHT. You do not want to look at it running. The benchtop now measures 160 lumens, up from 60. Great for a kitchen

23W is 3W above the rating of the fitting, but being CFL – I’m confident it won’t bother it. The 20W is also available in Dimmable, for those that want to replace 50W halogen downlights, although an electrician will be required, and the fitting is somewhat larger.

Another excuse not to go CFL’s down.

Are the MTZ’s tough enough?

Whilst my Mickey Thompson MTZ’s are on the best on-road tyre, they are pretty damn good offroad.

Their wear rate has been a little high so far, and they are vague on the bitumen, tracking and wandering a bit. It is improving as they wear down, but s straight line tyre they are not.

Here is a pic of them working over nasty stuff, mostly at 17PSI with a 100 Series Landcruiser and gear on top.
