    What's on your mind?

    ITT: what are you thinking about, right now? Me: surrounded by friends made of awesome and win. I could ask for little more! <3 atomic.
  2. I originally posted this on facebook, but thought it deserved a thread here as well... NBN Thought experiment for the night: Lets say you own an old house. This particular house needs the roof to be replaced pretty soon, as it's run down. A big storm comes along, and a tree branch falls on the roof, and damages half of it. Now you've got two options: 1) Replace the whole roof for $40,000 2) Replace the damaged part of the roof for $30,000 Issue being, that the rest of the roof will need to be replaced in another 5 years anyway, because it is so run down. So now, assuming you choose #2, you're going to pay another $20,000 in 5 years to get the other half fixed up. It'll probably be by another contractor who uses different construction techniques, and potentially not up to the same standard. There will also be a visible join between the two roof repairs that lets some water through, unfortunately. That's the difference between building the NBN all in one stage (as per current design plans) or in two stages, which would be required if we only did fibre to the node now, rather than fibre to the home (ie, Liberal vs Labor policies on the NBN). The copper WILL need to be replaced. It is a simple physical fact that copper can not provide enough bandwidth for our future demands for data services. So that means that if FTTN (liberal policy) goes ahead, we're going to need to go through and patch up the failed parts of the broadband network after the fact. Simple fact there is, that it is *always* a messy job to revisit/refurbish a project after it was completed, rather than just doing it right the first time. The current NBN design means that we will only need to build it once, it will all be built to the same standard, using the same hardware (this is a big thing, when it comes to operational expenses), and none of the fibre optics will need to be replaced in order to get a faster speed. All that would need to be done for faster speeds to be put through the network is a new device is installed in the local NBN 'exchange', and then as required the customers on that exchange can upgrade their speed if they need to - if they don't need to have faster speeds all their existing hardware will still work as it always has. My final point is - Don't take this as me saying that the NBN design is as good as it possibly can be. What you can take from this is me saying that the current NBN design is *far* superior to the Liberal police NBN design.

    Battery mowers

    I have to admit, the only reason i gambled on the Cobolt mower, was because of the price. Got the mower, including three batteries, for $450 or so. Half price from when masters was closing down. It's paid off for me though. Managed to pick up the victa line trimmer to suit it on sale elsewhere as well, think that was only $180 or something... dunno, was a while ago now.

    Battery mowers

    I've got a "Cobolt" 80v mower, reportedly it was made in the same factory as the Victa mowers at the time, not sure if still the case though. I love it, it's brilliant. I can normally do my front lawn on a single battery, as long as i don't let the grass get too long - normally i use about 1.5 batteries worth total, including some line trimming around the edges/non-mowerable bits. I've got the Victa 80v line trimmer - i use the same batteries for both - i just had to trim some of the grooves on the line trimmer battery compartment to be able to fit in the cobolt battery, operationally they're identical.

    NBN - Is it too expensive?

    I'm pretty lucky i guess, i don't get involved much in the business operations side of things, and primarily do engineering and design. Slightly more interesting

    NBN - Is it too expensive?

    It's worse than that. I work in a small ISP, that specialises in a few areas only. One of those is aged care villages/facilities (We primarily don't play in the retail sector at all, except for this). We installed our equipment before NBNCo began operating services in the area, providing residents high speed internet access for (very) reasonable costs. Typically around 60% the cost of a comparable NBN plan. Because our technologies we use are similar (or in some cases identical) to what NBN provide, either through POTS phone lines (VDSL), Coax cables(HFC), or even Fibre optic cables(GPON), we're technically a provider of NBN-equivalent fixed line services, and will have to pay the fee. That means our service prices have to go up, without any benefit to the residents. NBN, in those areas, have over-built their services in parallel to our own pre-existing services. So our choices become: Change the technology we're using so it's not NBN-equivalent (and don't pay the fee), or we increase our price. It feels like if we increased our prices, we're giving in to NBN, which only costs the residents more (we can't absorb such an amount if we want to stay in profit). If we change tech, depending on what/how we did it, it may decrease the performance or reliability of the services we provide. Noting, that we provide not just internet services, but also phone services (which includes a local-to-facility service between residents and their admin offices/services such as security gate control systems).

    The Atomic era concludes and we were magnificent

    Final request: every user on the forums becomes a superhero for the last 24 hours. It's been a crazy ride. Lots of friendships made, sometimes more, and most of them ongoing. Atomic isn't a mag, it isn't a forum, a website, and definitely not a business. It's us. Atomic has had a massive impact on my life. I owe it atleast two, if not all three of my IT jobs. Somehow unrelated, also had my name(s!) in print as well. Atomic has been suspended, shut down, broken up, blended, etc a few times. Despite this, it still lives on. Because of us - all of us, the users, the mods, the contributors, the staff. Everyone. It will still live on. In all of us. Forever.

    Yep i've got plenty of those too. They're fucking high compression.

    NBN - Is it too expensive?

    Yep, i've done stadium jobs too. Not 4G in that case, but high density Wi-Fi. And yes, DAS systems and Microcells can definitely help in that regard. That doesn't mean there isn't noise, just that we can control it enough (usually only just) for it to work at its limits. Stadiums do have the advantage of basically being a big faraday cage though, so you can design them with almost an expectation of nothing buy background noise levels in the area, compared to the big wide world outside, like suburb/city scale infrastructure has to deal with. No, not every home. eg, if i wasn't a heavy user (due to both personal and work requirements) i wouldn't need 100mbit. But 35Mbit is limiting what i'm able to do, particularly in my case due to the only 7MBit upload speed. So sure, lets say FHD video is 5-8MBit as you claim (super high compression there), and a kid needs to upload a video to either youtube or the schools online systems, then your internet is effectively unusable (in my example) until such video is uploaded. That's if you've got one kid. Sadly, there are many breeders in this world, so some families have more than one kid. Crazy, can't see why myself... but can't help some people.

    NBN - Is it too expensive?

    You said it. Nah, it actually took about 3 weeks and 7 tech visits. I managed to identify the fault in the first instance, but it took them that long to actually go through their processes to come to the same conclusion i did on my original day of cutover. And sure, it was a 1000% improvement, but when you start at shit, any improvement is a step up. I still get starved for speed. Granted, i'm not the 'normal' use case, but my current level of load will be normal soon - and i'm just one guy, no family. I know many people in my area (broadly speaking - a few suburbs around me) with families, who don't have the bandwidth they 'want' (for various reasons) a night. Mostly regarding study (video is a massive part of schooling these days) and entertainment. They could pay the ~20k to get FTTH connected, sure. As for wireless tech vs fibre. Think of it this way: You can fit *best case*, assuming future technologies are awesome, 1MHz-80,000GHz in a shared wireless medium. Realistically obviously much less, so lets talk Carrier bands + ISM. 800-1000MHz, 1700-2600MHz, a few gaps for 900MHz, 2400MHz and 5800MHz ISM bands, but obviously higher the frequency, shorter the distance (not always a bad thing, but not good for regional). In the second example above, you can do that frequency band, plus more (due to no radiating RF) on a single wavelength of fibre. We have commodity hardware now that'll do 5-2400MHz over fibre. It's common. Give it say 5 years and we'll probably see it go to 5.8GHz too, to encompass DAS over the same bands, without needing LO circuits for mixing. Using CWDM, 16 wavelengths of such a system is possible, so 16x the 'wireless' spectrum. How you do your return path changes total bandwidth of course, being either FDM or TDM, your call. Using DWDM, though unlikely to be required yet, you could do *with current tech* nearly 200 sets of 5-2400MHz. Now we both know (speaking to Leo of course) that the above requirements are more than we need now. And there's also no doubt that wireless tech will improve. I see the latest advancements in what i do as well. That's not to say though that those EXACT enhancements in wireless tech don't flow directly onto fibre tech. If you can run a 4096 QAM carrier over copper, i can do it over fibre, with less loss and degradation. Ignoring the other possibilities of a fibre deep network like additional services. I've already designed for clients an integrated network which encompasses GPON, NGPON, DOCSIS (as separate services on the same fibre), DAS (multicarrier + 2 way radio), and RFoG. On a single core of fibre (ok, lots of single cores being a passive network., but all services ACTIVE on a single core, no physical segregation). Don't get me wrong, i questioned the need for the above, sometimes segregation is good, and overkill is sometimes bad, but it was all entirely possible. And it was designed (thankfully not implemented!) Just like it's possible to swap out a line card in a GPON system, add NGPON to a service, add an extra MUX, and with only about 10 minutes of downtime per OLT you can suddenly have 10GPON services running over the NBN on the exact same fibres that are providing existing GPON services to everyone. Even on the same OLT, no need for multiples, just a new line card to activate the new NGPON services.

    Exactly! So a date would be *bloody* useful. Bit of a (massive) oversight, IMO. Ignoring the fact that an email should have been sent out to all users affected.

    So... that big banner announcement at the top of the green room regarding passwords.... When did that happen? There's no date reference on the announcement at all from what i can see... Wouldn't mind knowing when my password was compromised.

    NBN - Is it too expensive?

    I'm on the 2016 build list for MTM in WA... Which means, for me, FTTN via VDSL2, unless technologies change again. Knowing how old the copper is at my house, i'm going to be surprised if i get anywhere near 100mbit, probably closer to 30-50... That said, when it finally happens (probably 2019 for build completion), if i'm still at that house i'll just get it upgraded to fibre, if the cost isn't stupid high.
