Mystery of Milwaukee M18 XC battery resolved or "Will my saw work on compact battery?!"

Recently I had to do some emergency house repair: few planks of my entrance staircase gave up under my foot after rain turned to blazing heat. I went on replaced them with Trex. I needed some new tools for this project and that how I ended up with Compact drill and Impact driver M18 kit from Milwaukee. I had to upgrade a circular saw as well and as many people who read review

http://www.homedepot.com/p/Milwaukee-M18-18-Volt-Lithium-Ion-6-1-2-in-Cordless-Circular-Saw-Tool-Only-2630-20/202196549#.Uege7RZHY_U

I was a bit confused. Will Milwaukee M18 circular saw work with compact batteries I got in drill/driver kit? Some people said, no, it will not even fit in. You need big, XC one. Others said that it will work just fine and indeed from outside both batteries looked about the same, with XC just a bit bigger.

I picked tool only saw in HD and my compact batteries worked just fine. I looked trough manual, but could not find anything mentioning batteries. Yes, M18 circular saw did not seemed as powerful as corded Hitachi I had before, but it did what I need and set me free from long an annoying cord that was tangling on my deck.

Few days ago I finally found a website that explained the mystery :) and I run downstairs to check my tools and batteries.

The key is in special plastic guide rails on M18 battaries. It is very small and unnoticeable feature unless you know it is there :) The post I came across claims that compact battery have two rails and XC only one. Some tools have only one and that should prevent inserting incomparable battery even if it looks like it will fit.

Apparently both reviewers are right and it may depend on version of battery. My compact battery has only one rail, just like XC should and my saw has only one guide, while both driver and drill has two.

Speculation was that Milwaukee incorporated some overload protection in XC and probably they did same to compact version as well.

XC should certainly give more run time (40%) and it also claims 20% more "power" - it may be a good idea for more power demanding tools like saws. As for me, compact M18 batteries worked just fine on all 3 tools I got so far.

I love Milwaukee M18 tools and doing my deck without Impact Driver would be virtual impossible. Drill came very handy too, as despite a special composite deck screws that suppsodly can drill itself in, it was only working half of the time and I switched to pre-drilling to get a better results. While I did front deck with corded Hitachi - major workload of cutting, I switched to Milwaukee cordless circular saw for backyard and under deck repairs and it worked great (if not as forgiving when wood grabs the blade :)) and I loved cordless freedom.

iPhone 5 on ATT network use cellular when on WiFi with a scary rate



I got this bug too: iPhone 5 on AT&T "burns" cellular data on WiFi while idle and locked at approximately 5Mb per hour rate in my case. It started with suden battery drain on Monday, December 3. iPhone was out of juice in 4 hours  while in the pocket. It munched on about 20Mb of cellular data.

Contacting AT&T: not helpful. They said they NEVER hear about this. Yeah, right:

http://forums.att.com/t5/Wireless-Billing/iPhone-5-cellular-data-charges-while-using-wifi/td-p/3325005

Googling this issue revealed that Verison users had this bug:

http://news.cnet.com/8301-1035_3-57523893-94/iphone-wi-fi-glitch-may-affect-users-on-other-carriers/

and as it seems AT&T and other too now.

http://www.gottabemobile.com/2012/10/01/att-iphone-5-may-also-be-using-lte-instead-of-wi-fi/

I talked with Apple care several times and of course they also will not admit the issue :) Surprise.

Do you see pattern here? https://discussions.apple.com/thread/4348072?start=105&tstart=0

As what is nature of bug is not clear.

http://appleinsider.com/articles/12/10/01/bug-causing-iphone-5s-to-use-cellular-data-while-on-wi-fi-may-not-be-limited-to-verizon

AT&T suggested : "you installed the app!" and "50Mb per hour is OK. We seen that!"

Apple said to wipe the phone and sync it back.

I spend few days debugging "old image" and turning off all kind of "background" things like iCloud. I must tell - mess. iOS 6 became so bloated with crap - you have to flip many switches to make sure nothing is done behind your back. Bottom line - did not helped. So I wiped.

Interestingly enough it seems to help till I added 3d e-mail account. Then it started to use cellular again. One of the "cool features" is that every time I was using email account, some few K went over cellular.

Apple care again: we come to conclusion to turn LTE off: apparently LTE is evil and 4G/LTE hooping in  boundary area some how use cellular data just for search. Megabytes per hour? BS! But OK. It is OFF and for 10 minutes it seems to help. But ... it did not. While in the pocket on WiFi in company it eat another 4Mb or so.

AT&T account show exact correlation - I am billed for all this data.

Called Apple again - long story short - all email is now in Manual. Exchange server admin now is one to blame for this mayhem :)

Celular is ON again - testing...

One more theory is that WiFi modem is off when phone sleeps so cellular is used. This is clearly BS: nothing changed in use pattern that for this phone was under 160Mb a month (it is virtually always on WiFi) and my 4S with more cellular use only use Kbs especially for send - while iPhone 5 use Mb for idle send.

Well, nobody admitting the failure and nobody offer me refund as of yet :)

I keep my fingers crossed for Apple to fix this bug ASAP. It is REALLY very annoying and turns "smartphone" to "stupid phone" again as you can not keep cellular on and you can not trust your device anymore after this crazy outrage.

If you ask me iPhone should be 100% accountable  and transparent for data traffic and I should be able to "ban" all underground activity with ONE SWITCH if I must. Let it ask me if I allow application to use cellular internet and for what.

My 4S is Unlimited, but this is not just matter of $: data modem use means battery drain. I so miss iPhone 1 without multitasking and background sync crap :)

iPad mini review and how it compares to Nexus 7 and iPad

As you all know, iPad mini is out :) great, but how to get it? I was looking to get Kindle Paperwhite but no luck - 5-7 weeks wait?! I liked it - one of my friends got one, going through all generations and he confirms that it is a best Kindle so far. I called Apple store but no luck, so I went to another super secret local store and was able to compare iPad 4 and mini. I wanted to upgrade my generation 1 iPad. Not because I did not like it - still use it everyday but because I need to pass it over and get myself a new gear - I really have no issue with the old version device number 1, even if it only goes up to iOS 5. I mostly use Safari, Kindle, the mail app, and games - all works just great for me, but 4 generations, may be I do need an upgrade. So I was naturally thinking about iPad 4 - I like the size and I like smaller Android tablets less. But it was enough to just hold the iPad mini and I was sold - screen size is not that much smaller but it weighed like half of the android tablet and was so small - magic :) it also cost less, worst margin for Apple ever - so it must be good. When I saw the box I was thinking that brought me iPod touch so small and light, but it had 'mini' written over :) so, how does it compare?

First, iPad is awesome device - love it, but mini is so cute and light - it fits my coat inside pocket - I was afraid it will not as it looks like almost same screen size as rearguard iPad but it does . I can hold it with one hand! So it maxed out on screen and made as big as it would fit your hand or pocket :) half the weight:)

It is bigger than Nexus 7. Just a bit. My wife have really small hands. She can hold Nexus 7 comfortably but mini is a bit of stretch . Still she likes it. It feels more like a new iPad than mini tablet - just same feeling when I moved from 15'' MacBook Pro to 13'' Mac Book Air - size and bulk gone but all experience and screen size is same or better (faster - it is much faster than my iPad 1 :))

In comparison Nexus 7 feels like mini tablet or big Android phone - just a small difference but it change the feel.

Now, of course mini is 64G of memory and 2 cameras. Main camera is quite decent. This alone put Nexus 7 to shame - still very very angry on Google for saving 2$ and curing off camera.

So, mini is awesome. Fast, luxury elegant and think, you can max out specs to load your music and even videos and you can get cellular - I skipped it as it was not used much in my iPad where I had it - I was too greedy I think and used iPhone when I need connection :) anyway, to get anything cool it is extra 30$ a month and I passed to save a 140$. I may regret it but oh, well :)

While iPad mini is half power and resolution of iPad it has same pixels and just tad smaller but half lighter and less expensive :) winner, clearly, for me anyway.

Compare to Kindle Fire it is much lighter and thinner and of course, it is a full iPad expirence.

I do not feel a need for Kindle paperweight - Kindle app works very good and the screen is awesome plus it is about the same size and weight :)

Just one warning: if you will find iPad mini in store and hold it in your hand ... You may just find yourself going out with one. :) yes, it is that good (I am an Apple fan , sorry - take it with a grain of salt. :)

iPhone 5 dings and scratches

I went to pickup iPhone 5 to Apple store. As I did some research, I opened box right there and lo and behold - few dings in bezel. While it is minor, I was kinda shocked to get this from Apple - it must be hard to keep up with demand and keep quality. Device itself worked brilliant and is best iPhone I had so far (from v1). Of course Apple ordered me a new one and I swapped it in two days - no scratches :) Apple care about customers and this is just a annoyance of course but I think execution have to be better as such issues should be easy to foresee - what kind of dumbass at Apple designed such a high travel area from anodized or tinted aluminum ? Even brushed aluminum could be a better solution. While most people use protective case, I dislike back - it gonna scratch like hell and looks nasty - what are these panels? Why it is not one part? IMHO - fugly, just like iPhone back was on 1. 3 and 4 for it right - plastic or glass - one smooth and good looking back, but 5 has a mess again with it ugly glass/scratchy aluminum - why, Apple? I know it may improve strength and reception but looks and design was always important for company. Oh, well, we just slap a cool case on it ;) front still looks iconic , thank you for that :)

So far, everything else works fantastic and fast - beat iPhone ever.

LTE is noticeably faster than 4G - browsing Internet is a blast and camera even more responsive - two key features we use every day. You will see less in games - Angry Birds still looks and play the same - just great :)

Thunder, lighting, USB and old audio connectors: iPhone 5

Lighting seems cute, but redundant - Apple should be curing the wire ;)

What we know about Windows Phone 8 aka Apollo as developers before October 29 (when we supposedly can get SDK and find out) ?!

If you read this you will come up with summary bellow that answer important questions we mobile developers have (while WinPhone is nothing significant today of course - no Android or iPhone :))



1)"As of Apollo, the Windows Phone OS will include the same file system (NTFS), same networking stack, same security elements, graphics engine (DirectX), device driver framework and hardware abstraction layer (HAL) as "big" Windows. Apollo also will include the mobile variant of the same browser -- Internet Explorer 10 -- as Windows 8."

2) Microsoft execs have said repeatedly that existing Windows Phone 7 apps will run on Windows Phone 8. The two phone platforms are binary compatible, Sullivan reiterated.

3)Developers cannot take their Windows app binaries and just run them on Windows Phone 8. However, there is a high degree of code reuse possible, Sullivan said.

4)We know Windows Phone 7.x apps can run on Windows Phone 8, according to Microsoft. But what about the reverse? Can Windows Phone 8 apps run on existing devices? Short answer is no.

5) "The Silverlight-based Windows Phone developer environment is going away in Windows Phone 8, and is being replaced by WinRT-based APIs like those in Windows 8. Why? Two reasons. First, Silverlight is dead, cancelled internally by Microsoft. And second, Windows Phone 8 is Windows 8 for all intents and purposes."

6)Microsoft has decided not to include XNA support for WinRT/Metro in Windows 8. It's only supported on the Desktop. With Windows Phone 8, according to one of my tipsters, Microsoft still will support XNA in the Windows Phone 8 software development kit, but will be pushing developers to write games for the platform using DirectX and native code, not XNA -- just like the case with Windows 8.

=======

Microsoft's advice to phone developers going forward, just like it is for Windows 8, is to use native code, meaning C and C++

It is beyond me why Microsoft keep the bits out of our hands even after OS is ready and frozen. Apple start sharing years before release and this is a way to go, IMHO.

BioLite is the SHTF stove you need!

Some folks take Zombicalips literally: they stock up on guns and ammo and Twinkies, using Zombiland DVD as interactive video manual. But how you charge your iPhone when all goes down?! BioLite stove is coming for your rescue. First, it does not need any real camp stove fuel: twigs you can find nearby may be quite enough, assuming you stocked on fire starters. Second, it can charge USB powered gadgets if you are ready to keep this fire going :) biggest question is internal battery - how long it will survive in post - apocalypse world? I like my camping gas Primus and use it on every camping trip - but BioLite is very promising and I will keep on testing it. It does work, but you need keep adding twigs and there are only two power settings - hi and lo - not a problem for boiling water, but may be more problematic with pancakes. We will see. So far it is very promising.

Google (ASUS) Nexus 7 hands on review from developer



No, I did not get it at Google IO extended (I wish ;))  but I was lucky enough to pick one up at local Office Deport. It was sold to me from under the counter :) there are still just a few around, but as it common with Android devices there is no line and nobody even pick these tablets to look. It is not Apple store story. Not yet. Even so many people get Android phones (and then some go back to iOS ;) if they lucky enough to try it as even geeks realize that Android is not free or open and very buggy at that (crashes and such) - you are under DOUBLE lock - Google OS and OEM - good luck to get s/w update or install firmware you want. Rooting device is for real nuts - they waste their high prices skills on BS, IMHO.  On user side: you have to grant crazy permissions to apps you install - essentially you give them all control. On Apple device they ask for specific rights and you can deny - app may still work and live in sandbox as they should :) See where is more freedom?)

Note: Despite my "view" of Android I wanted to love this device :)

As Android developer I wanted Jelly Beans and as it common with Android hardware you gotta get a new device even for minor OS update as you may never get it otherwise or wait like a year (and Google will jump over a few API levels at the same time) Note that both Microsoft phone and Android sucks like that: when Apple push out beta I can install it right away and they do a very good job to support even old devices even when it means dropped features.

Apple is just great :) I am a huge fun :)

OK, so back to Nexus - it does looks a feels like a "bad copy" of iPad/iPod. Sorry ASUS and Google. It is OK device so far, but ASUS/Google went to a great length to make it less then stellar to own.

First: 8G - ha ha ha - I bought 16G of course but hey, how you use device without Internet without 8G? May be a bit hard. Many will get cheaper device and will not be happy soon enough. No SD card - make sure you do not put too much music and forget about video. It is OK if you have connection to cloud, but last time I checked on the bus and camping it was not there :) Note: As developer I do  not really carry about this much, but no SD means I can not test SD and for Android devices it is (or was) important as things did not worked well in OS.

Second: Camera - yo, duh! You suck, guys. Device is small enough to fit my cargo pants pocket, yet it only have really crapy 1.2 M front camera. Google even remove camera app (you can get a hack from Play store). Really ? Google and Asus? You skimped on camera? With your G+? How pathetic from Vic Gundotra to post a beach picture on his G+ wall about how he loves use Nexus 7 there. Catch : he took picture with his phone! Duh! Two devices while reclining on beach? Shame and huzpa. Nexus 7 should be EXAMPLE device. Not this. All other Android devices have like 10 cameras :) my G Slate has 3!

This is big problem: as developer I want as much hardware  in device so I can test it. Nexus 7 has an omission here.  Yes, I can probably use sucky front camera with a hack but why skimp on couple of bucks?! (to make me buy another device in 6 month?)

How Google designed device for G+ and removed a usable back camera from spec? Beat me. They must be coping early iPod Touch story, but hey, it is not same time anymore.

Bottom line : forget Augmented reality and other cool things you can develop for Nexus 7 - no camera. Bad for users, bad for developers. Really big issue of device that has a from factor of oversized phone.

My kids play with cameras a lot and they can not use Nexus 7.

This is my biggest complain - Google and ASUS you SUCK!

Third: OS and device have bugs. WiFi drops more then it suppose to. Google Play DRM fails at a time (could not always brag with free Transformer flick ) some times device not very responsive - usual things and it just not pleasant - Android as usual - it is not always just works.

Buttons are hard to find - need getting used too. Same for OS navigation - Android desktop is to o confusing for small device. Amazon Fire is MUCH better in this respect.

Some popular application does not support device yet: Amazing Alex from Rovio is example.

Bottom line - it is a solid beta product.

Now good things:

I like device form factor. It is better Android from what I saw. Kindel app works. Screen is good. Games I tried run good.

You may want to snatch one if you are developer, but if not you may be better off with even 200$ iPod Touch - smaller screen but better device and OS. Of course, new iPad is a dream compare to this. I still prefer bigger screen and iOS for my bed time reading or bus ride and when I on the go: iPhone - anything else is too big.

Google voice recognition is good. It works better than Siri for me. I have a very heavy ascent as English is not my native language :) Some times is silly: it replace curses with ****. Obviously, Google search fails as "****" is not used on Web much.

Bottom line: OK device. Aggressive price may be attractive to some. I can only recommend it to Developers and only under reservation that Google will keep up with OS updates. Minus points for no SD and no back ("main") camera - bad thing for developers.

Even if you are on the market for other Android device, try not jump on the hype and look for alternatives to Nexus 7. While OS on Nexus may be OEM clean as it can get, try to find hardware configuration you like: max up memory, camera quality  and SD if you use it (say to transfer images from "big camera" to Google + while on the trip).

If you want to get Android mini tablet to your older parents do consider Fire. I was thinking that Nexus 7 will be Fire killer but I take my words back: Fire, while balkier, has a very simple "book shelf" interface that even old people will understand. Nexus 7 is usual Android mess and it is hard to click on things - I was fat fingering much. It get's tiresome after a while. I never had that much issues with my much smaller iPhone screen for example. Android UX is not simple - it more of desktop with all it gadgets and things. IMHO: it is wrong. Simple "pages" (Apple probably copied it from Palm that got it right a very long time ago).

One more thing for developers: Jelly Beans and may be Nexus 7 breaks some apps. It broke our main app. So far problem is small (cosmetic) and probably we did some thing wrong (but it worked with all other version): background of our screen turned black (and we used grey font - it looked great on white background.) I did not looked yet why Jelly Beans does it but I assume it will be 5 minutes fix for me. Gaming companies like Rovio probably have a bigger issues: they pull some apps off for this device.

Other than that, get iPod touch or better yet iPad instead - you will be a much better camper and kids will love you ;)

Update:

1) Fixing UI in our application for Jelly Bean was indeed a 5 minute thing. Fixed and tested, we will push update today (hopefully).

2) One more awesome feature found and tested: Face Unlock. It really works at lest here around an office :) Good job Google!

Update:

Note about memory: When you get 16G device you have like 12G (that what my device shows) before Google updates. ;) When you get 8G device you have like 4G or less left. Do not get confused by "marketing". 8G model is surely not enough for anything but a few books and games. If you get 16G(12G!) model you can put a few songs there ;)

And no, I did not downloaded Google promotional Transformers flick or MP3s: I just installed a few apps and got a couple of songs to test sound - sound is great, btw.
