Gadgets?

I'm to the point where I think I need a gadget box... but what should I put in the box? Well the purpose of a gadget box is to help me organize my every day carry and even my hiking gadgets. But when I think gadgets I'm thinking things that require power.

Just looking at my desk I have 6 flashlights each with different battery types including USB rechargeable. I have at least 5 headlamps. 3 power banks of different capacities. Many different cables and all warts. And my waterproof Lumix camera. And plenty of batteries too.

The thing of it is that these devices are spread all over and not just on my desk. Sure would be nice if they were all in one box.

how much is too much gear

Falling back on one of my themes about just in time manufacturing, lead times and the cost of custom gear I'm giving away gear to a local group because it'll be wasted otherwise.  These plastics are not going to last forever in the Florida heat. Just sitting in the garage they start to deteriorate. So I'm giving it away rather than cluttering the garage and making gear decisions before a hike.

That means if I have a failure I need to be able to order it and have it within a week.

It's a simple task but has consequences... the gear will probably be manufactured overseas, in bulk, and probably have some quality issues. Of course this is no guarantee that local sourcing will prevent that from happening or improve the numbers... But comparing the stitching on any of the custom work with Paria and it's no comparison at all.

My active inventory needs to be:

a 1P or 2P tent for when I know it's bad weathera tarp and bivy for when it's just hota hammock for those fu…

Amazon refuses a review

I like to review things I purchase on Amazon because somewhere in that machine is someone taking note that not all these products are worth it... and maybe they would protect the brand or even the consumer. But when Amazon allows the merchant to prevent reviews well that;s a shame on both their houses.



TITLE: not for candles

REVIEW:
This device is too big for every day carry as a lighter. Does not light candles well as it requires a steady hand not to get wax on the probes.

sizable cordage

Bushcrafters talk religiously about their 550 paracord. There are plenty of uses for paracord and survivor cored if you find yourself in the back country for longer than 3 weeks. And depending where you are and what you are doing a whistle or cell phone is sufficient because if you are in that kinda danger f*ck survival make a call.

Considering the volume and weight of 550 paracord I like this Dyneema from Atwood.
It's made from Dyneema and can support 550 pounds just like the 550 paracord. The best part is that this small 2 inch spool holds 61+ feet of this cord. Sure Dyneema is a bit slippery but it's manageable. But the compactness and weight makes it ideal to carry extra and it also packs downs small so more impromptu setups like wider trees or other configurations are possible.

Also from Atwood are some reflective and solid braided strands that are more compact at 125ft per spool. Let the testing begin.

NOTE: most tarp configurations need 50ft of cordage. Tents need much …

the cost of who's watching

I was watching a John Oliver clip on the last week channel on youtube when I noticed that youtube was offering season 5 for $24.99.


H*ly Sh*t and WTF!!
A normal broadcast TV season is between 23-25 episodes so to keep the math simple lets say 25 episodes. That means that Last Week costs $1 per episode. One can extrapolate that is about $1 per hour of regular TV where the dollars are divided up between the production company, the distributors, affiliates, residuals and so on. In the regular TV world that cost is paid for by advertisers because they think they are going to make that dollar back through sales.
What is interesting is that in the "over the air" world viewership is determined by systems like Nielsen where viewership is determined by surveys and lots of math. But in the cable and online world it's actual numbers captured by Tivo, and browser cookies. The former being essentially anonymous and the later being breadcrumbs through your day.
So my question is ... i…

what's in a color

When I started hiking I made the conscience decision to avoid gear that was red. The idea was that if I were bleeding I wanted to know and for it to standout. Then about 6 months ago I decided that black was an interesting color because it would dry my gear more quickly. That included my poncho and at the expense of being seen.



Last week I purchased a "Black Pearl" kit from Light My Fire. It's a Morakniv knife with included fero rod, a spork, and tinder; all black. Soon after I placed the purchase I found an orange spork in my kit that was dirty. At that moment I realized a black spork was a bad choice. If the kit was dirty it was going to transfer. Yuk!

more than one use

The challenge or problem with selecting kit where something does more than one function means that a malfunction means more than one use might be compromised. For example using a poncho as your shelter (tarp) means that a malfunction of either function compromises the other. Overlapping function makes more sense.

I am becoming more attached with my Snugpak gear because for the extra weight it is quite robust. For example the Patrol Poncho is a poncho but cannot be used for anything else.




Continuing; I have a jungle bag and a jungle blanket. In hindsight I'm not sure why I bought the blanket because the bag opens and can perform dual duty. They are about the same weight. The only difference is the internal pocket, mosquito mesh, zipper. (zippers might not be hammock friendly.)

Recently I have started to use my Patrol Poncho. The best part is the pocket. It keeps my hands warm and dry. But then Snugpak also offers a poncho liner. The liner is essentially a jungle blanket with sleeve…

Solar Camping

When I take the kids camping we depend on certain modern conveniences.
fan when it's hotiPad when their boredLED lights at night to see in the tent and prevent our friends from tripping over our guy linesheadlamps or flashlights for getting around6VDC rechargeable pump for the air mattresses Many of my peers rely on 120 and long extension cords, However, at some of our locations these resources are limited and from time to time the host vendor will unplug us. At least two peers have CPAP machines and they need the battery option to make it through the night.
Battery power has many challenges especially in large groups including kids. It's not like you can plug-in to any socket and expect to find it there when you return. During a recent trip a kid reached into my car's open hatch and to a friend said she was going to "steal" some bug spray. Steal suggests that she knew the difference between right and wrong. So something similar might happen with rechargeables whe…

Jupiterhikes - 6lbs on the PCT

Just another example where price meets going without but from the going without it's probably OK for a weekend:

Versa Blanket

This past weekend I slept in both a hammock and a tent. The temp at 2am was about 77F both nights. The blanket is not quilted so the shell will stick to any moist skin and getting the right lay can be a challenge depending how awake you are.



By comparison the Sungpak weighs 100g more, however, it is quilted and feels more like a proper blanket. In retrospect the jungle bag is the same product with a zipper and a bugnet. If I had sprayed the hammock with permethrin either one would have been perfect.


The Snugpak gives me more options although I would have preferred a more visible color.

Lastly, my biggest complaint about both is that the stuff sacks are tight fitting. You'd think that the compression straps would make up for any extra room but they don't. It takes effort. In the meantime I don't use the stuff sack instead I use a pack liner.

bushcraft kicks in

Another lesson learned from this weekend's camping trip, with my kids, is make your stakes.


For this trip I brought a tent, for the kids, and a hammock for me. I keep the stakes for the tent in the bag with the groundsheet. The hammock was new gear and I have not bundled the kit as evidenced by my misplacing the bugnet and forgetting the stakes for the tarp.

Unlike previous setups I used toggles for the ridgeline as the tarp has linelocs built in with cordage pre-installed with loops on the end. For the other tie outs I fashioned stakes from some branches. In hindsight I should have used some green wood rather I used what was at hand. One stake failed so I simply used an exposed root. toggles=no special knots.

The Perfect Bonfire

Getting the perfect bonfire is subjective, however, in my case I can define it... 15-20 ft flames lasting 1-2 hours. I'm no expert and there are no howto videos, blogs or manuals that I can find.


To the right is a pseudo Swedish Torch.  I took 5-6 log segments and formed a log; then used some bailing wire to hold it together. On the first night the torch was lit with "fat wood" from home depot and some lighter fluid. For an ignition source I used a yellow torch from Home Depot. On the second night I only used the fat wood. Ignition was achieved using a fat wood feather stick and a small lighter.

The bonfire was constructed from 3/4 cord of wood.The core of the bonfire was a log cabin about 5-6 coursesThe outside was a simple pyramid making certain not to block the holes letting air into the coreMore fat wood as kindling at the bottom of the log cabin with some extending to the perimeter of of the pit On the first night ignition was achieved with 3-4 liters of lighter flui…

Ready for a hike?

This weekend I took my kids for a camping trip with our Indian Princess group. No matter what I did I could not keep everything under control. The strategies for managing clothing pre-sorted by day and in Ziploc bags simply did not work. Finding band-aids or toothbrushes or water bottles or even the right snack was overly complicated. Amazingly the lists are VAST.

Hiking is no different. The number of pockets in a pack is going to make you less efficient. Too much or too little can define success or failure. Whatever it is there is a fine line to success.

traefik in a box

Before you begin there are a few decisions to be made. The most important is whether or not you want to support wildcard domains or strictly limited to well known host/domains. If you choose to use wildcards then you are limited to dnsChallenge and there are a limited number of providers not to mention that you need credentials. (see providers)
choose hardware and operating systemoptionally install docker-machineinit a docker swarmcreate a swarm networkcreate the 3 config filesLaunchBasic Authenticationmy app configurationLaunch my appAll in one FIRST you need to deploy machine that can be physical or virtual, however, in order for it to deploy SSL via letsencrypt you must have a public IP and registered DNS and nameserver. Depending on the DNS strategy you may need to create the A-record. The host OS you select should or must support Docker. I prefer CoreOS or RancherOS.

Not all OS' pre-install docker-machine and many container OS' use read-only partitions in order to maintain…

dynamic sizing and reporting services

Most developers and system designers underestimate the complexity of reporting systems. Sure the first few reports are easy and sometimes downright trivial but that does not last long as you become the product of your success.



First of all there is challenge with concurrent reporting... just how many reports can you run at once? That's partly a network bandwidth thing and a memory thing and a computational thing. But it depends where the reports are being executed, local or remote, and whether the DB is sized properly too.
Then there is the catalog of reports and the largest with the most computational stress and the variable idle time between reports. And then there is the reporting schedule and the manual demands; all of which have queuing theory challenges.
Of course then there's report delivery and it's challenges, archiving, replication, consistency between reports, formatting, and security. And it gets worse.
My current challenges right now is that my static reportin…

linked-OUT

Recently there was an announcement that Microsoft purchased or acquired LinkedIn. I do not know what the play is because it's not much of a social network and it's not much of a business network. When I joined, many years ago, I linked to anyone and everyone I could. That included recruiters, executives, and many 2nd and 3rd tier contacts. I had some stupid number of connections.

In recent years I have been getting connection requests from more and more recruiters. Non offered real jobs. Many were looking for programmers with 5 years experience... I've been a programmer for 30+ years. Why are these dolts contacting me? If they would spend 5 minutes on my resume they'd know exactly what I'm good for. I FIND AND SOLVE PROBLEMS.

And so I started dumping my connections.


REALLY! I only have 33 connections. None of the other 500+ connections ever reached out. These 33 have not either but they are more likely to respond to an email or a message.

PS what's also amazing…

it's a spork or trash

Pissed off


damn spork cracked while I was hand washing it. I admit I put some pressure on it but I was not expecting that.

Just rain

Last night the kids had soccer practice. The evening started off pleasant and I managed to start re-watching season 2 of Bosch. At 730p it started to mist and then quickly sprinkle and then it came down in sheets. Luckily for me I had my Snugpack poncho in my backpack so without skipping a beat I pulled it out and slipped it on. That's when the kids started to run off the field.


Sitting under my poncho I was very comfortable. I really like the chest pouch and pockets. The neck zipper and adjustable hood were excellent. Unlike other ponchos there are no side snaps it's already closed so it will not be useful as a tarp or groundsheet. As it is black it will dry quickly but it is hot in the sun.

I'll have to try the Sea to Summit next time.

PS there is something to be said for carrying my BOB to the soccer field.

traefik one domain multiple IPs

Things get crazy if you have a domain that you want to manage with more than one public IP address. You need to know a few things before you go crazy with traefik configuration so let's list things...

[a] you have 2 IPs
[b] you own the domain and have a nameserver
[c] you might set a wildcard A record and you might also set some hardcoded A records
[d] you configure traefik to update your nameserver and you do all that config foo

What I determined was that the system with the wildcard will get all the default or unknown name resolutions... that means that the second IP needs to have all of it's host subdomains set in A records.

I tried more than one domain as a wildcard. For the moment it seems to be working but there is probably a timeout or cache thing going on.  Let's see what testing does.

docker and system memory

I created a 1GB server on Digital Ocean, installed CoreOS, docker-machine, docker-compose, deployed traefik and a simple whoami container.


I'm pretty certain that it does not support swap even though it has not started to use any but I do see that just that little bit of work used up 800MB (including the OS).

What this tells me is that 32x 1GB machines are not the same as 1x 32GB machine. The overhead is just too damn high. On the other hand there is something to be said for adding systems to expand rather than taking the downtime to resize and re-deploy the resident apps.

SSL sucks

Don't read this post unless you want to read about FAILs.

Trying to deploy a secure "developer in a box" domain is non trivial. Which also means that trying to deploy any kind of domain is also non-trivial. The challenge is the bootstrap which is also a "race condition" or a "chicken and the egg".

For example in my system I have a single public IP address. The router forwards ports 80, 443 and a few others to my traefic server. My traefic server allows my projects to register with traefic so that their various network requests are forwarded properly. However, since my traefic server is also version controlled in my private git repo and I cannot deploy traefic until my git server is also in place. And therefore the chicken and egg.

As for the SSL title... when you let your SSL certificate expire because it's too hard to remember what you had to do last time to renew and reload the certificate or that you've imposed too many guardrails in the or…

you bought what?

I have no idea what this guy was thinking or if he's even telling the truth. As I listened to him wander about his condo home office telling us about moving and putting things in storage he started talking about his computer that he dismantled. WTF! I've moved many times and I've always boxed my computer last for the same reasons. Then he goes off and spends some stupid money on a non-modern laptop with an exotic docking station. Then we hear that he has a mac at work.


So maybe he does not work at home. But what's with the exotic docking station and the older laptop with a "maybe" runs Windows 10?

I clearly missed something in the video but if all this was really all that important why not just get something that could run Chrome or even a ChromeOS machine and use it for the basics? For that matter get a tablet and a bluetooth keyboard; that way when your home station is restored you have a different use-case...

or is there some untruth in there?

when 25 is less than 18

Two packs.... a Naturehike 25L and a Klymit Dash 18 (18L) The pictures are not to scale...


But when you picture them


The 18 is clearly bigger than the 25.

The ultimate backpack

I'm struggling to find the perfect pack and it seems that it should be possible. It seems obvious to me that the pricing is a function of labor costs and materials so generally speaking if the packs are made assemble or manufacturers in bulk the cost will be lower. And for the same reason as before something that can be shipped in 24 hours has an advantage.

1) Price: $15-$50.

2) Weight: under 1 lb

3) At least 1 stretch pocket for instant access to food, larger water bottles, rain gear, tarp etc

4) shoulder strap pockets for water bottles

5) One main compartment 30L with a drawstring closure and an inside pocket.

6) Some way to carry a bedroll/cell mattress

7) carry capacity 25 lbs (10 lbs food, 2-3 lbs water, plus other kits)

8) comfortable straps

9) foam pad back

10) overnight delivery

Hyper Dynamic Development

Back in the day IBM decided that it was cost effective to turn off the lights, turn off the monitor and computer.... and to wait for it to boot up in the morning when employees arrived. Similarly there is a daemon called inetd that would listen to various network ports for remote access. When it sensed a connection it would launch a command. Basically responding to a request on demand. This had a number of side effects in latency and performance but it did mean that system resources would not sit idle consuming resources.

I have 4 Intel Nuc systems on my desk. Each cost between $600 and $1100. That goes a long way especially when trying to get some work done. One real challenge is that 2 of the machines are running CoreOS and 2 are running VMware and I just cannot control the upgrade process and maintenance. Additionally Let'sEncrypt SSL certs are painful to manage. And in any 24 hour day I'm not always writing code or sitting in front of the console. I really want to be able …

Docker vs VMware .. again

I'm staring at Google+ and switching through my browser tabs and I stop on the Digital Ocean NEW Droplet tab. I see GitlabDiscourse and Ghost one-click machines and I'm sad. At the moment I'm thinking about a developer in a box approach to dev-DEVOPS and what happens once a second person joins the team. The fact of the mater is you cannot just roll an entire system that people depend on for an upgrade of the base system(s).... whether it's VMware or Docker makes no difference. What's worse is that I have docker systems running on VMware systems and it's clear that recycling the hosts is a challenge with an interruption of service consequence. Bare metal solutions do not solve that problem either.

The only way any of this seems to work is if you have twice the basic hardware so that things can be located and relocated as needed.

3 Variety hamburger casserole

There are so many variations of the hamburger casserole out there but they all start like this:

Google Plus no more

Whatever happened Google seems to be dumping Google+ and I'm OK with that. Google+ seems to be pretty useless... it was never a better twitter than twitter and never a better blog than a real blog. On the other hand Blogger (this platform) has yet to receive any sort of face lift. MEH

Now, if only there was a way to import my content from Google+ to my blogger timeline?!


Stripping down

I have bunches of ziploc bags all over my space and it's driving me crazy. Also this weekend I cut myself at my daughter's soccer tournament and I realized I did not have band-aids or tape even though I was carrying everything in a pack. Now that I have everything tucker neatly into my Klymit Dash-18 I need to figure out what kind of EDC I need.
This started off as a crappy mess. Too many bags.


Now that I have removed the bags and de-duped let's organize.


I've organized the first-aid, daily, fire kit, everything else.


Now I have everything, except the food, in a one gallon bag.


And then I pulled out the first-aid and daily kits for my travel bag with the kids: sunscreenbug repellentlip balmhand sanitizerduct tapeband-aidsneosporinfoot balmswiss army knifetweezersTumsImodiumAquamira tabsTylenol and AdvilBenedrylleukotapepadded tape Watching some of the SUL hikers pack their bags I could do with about half this stuff but there is something to say about having it too.

MSR Hyperflow and Nalgene

Filtering water in the everglades is necessary as there are all sorts of bugs and floaties out there and it's also necessary to prefilter too as there are many sources of water that may damage normal sawyer-type hollow fiber filters stranding you in a place without water and few options other than getting off trail and genuine risk to human life.
Drink unfiltered water at your own peril. Lot's of hikers have their own way to collect and filter water in Florida. Many use their Gatorade bottle to collect dirty water and filter that through a coffee filter into smartwater bottle. Some will filter that water into a clear bottle and some will drink directly from the filter. I'm not a fan of the later due to the possibility of cross contamination.

After my latest experience I have a new plan.

STEP 1: tie my sil-bucket to a piece of cordage. Put a rock in the bucket and toss it into the water. Pull it out and find a spot away from the waters edge.

The right pack

Today's adventure was not really a hike although given the size of the park it could have ended up that way. My kids started a two day soccer tournament this weekend. That meant folding tents, ponchos, a small tarp tent, 32oz water bottle, few snacks.

When we arrived at the field I was watching the game before us. I had my pack and the folding tent was still in the car. At one point the rain started and about 5 minutes into the rain, wearing my poncho, I decided to setup my tarp. It was a half pyramid with 5 guy lines and one pole. I managed to finish the setup only to get a call from my wife that we were on the wrong field. So I broke everything down and just balled it up into my pack.


LESSON #1 - If the pack is just the right size then there is no room for rushing. My kumo pack is huge and so there was plenty of room, however, I'm reminded that the "hikers" talk about keeping the days tools in the outside pockets. And now I know why. Rushing to get in and out of th…

I'm not a coach but...

When I was a kid I played baseball in the spring and soccer in the fall... or something like that until I was in high school when I finally tried out for the Sr soccer team (as a junior). As a goalie I was not cirque de soliel but more hulk smash... and fearless. So I got the starting in net; and I fought to keep my job every day. At least that's how I remember it. I did not finish my senior year on the team and that was my choice not to mention another story.
After playing 2 years of rec soccer between the ages of 5 and 7 my daughters have developed an affinity for the sport. They are actually pretty good. Last year we moved them from the rec team to the affiliated travel team. Both are interested in what they call "player development". There are many facets to player development that I think we can agree are partly mental, endurance, skill and aptitude.
Last year they completed a 4 month section with the team and they spent most of their time learning to dribble. The f…

IT infrastructure best practices

Yikes! Do the masses get lost and confused in the buzz word and buzz tech of the day. Let's consider:

Taken separately each item in the list seems like a good idea and together they feel like powerful tools. In practice, however, there is no magic brush that allows you to paint the Mona Lisa in a single stroke. Even in the most ideal HA cluster scenario there are so many dependencies that have to be addressed and at some point you have to make decisions on the many single points of failure and risk.
For example; building a docker swarm from scratch from a batch file is pretty simple. Just configure and license one or more VMware or bare metal docker servers and deploy to your heart's content. Make sure that the containers you install are tru…
