In the 2 1/2 years he worked for us, we had a total of two issues. First time it was a storage array went down, and our regular DBAs were having difficulty bringing the dataguard replica back online - Our Senior DBA resolved it within 5 minutes. Second issue was an application corruption that we got stuck into the weeds with until, once again, Our Senior DBA just stepped in, restored a backup and then rolled us forward just before corruption occurred.

And no service credits, he was just an extraordinarily talented DBA - we were happy to have him set our architecture/monitoring/database deployment mechanisms. I'm guessing he worked around 100 hours for that 50K over a year, or about $500/hour, which, if you think about it, for someone at the very, very top of their Oracle (or Cisco, or Java, or Hadoop, etc..) technical game is really quite reasonable - particularly when you are only paying them when they are absolutely needed, and the rest of the time your staff DBAs can handle the day-to-day.

Hi everyone :)

I want to share with you – a new task management service that I have been working on for the last two years. It's been quite a journey.

At first, it might not look like something new, but we have a big dream that we are following – One centralized system for your team. With kanban, chat, time tracking and more thing each time needs - all in one place. We also want to sync with other systems. Of course, not everything is ready yet, but we are working on it.

Thanks for reading and I would love to hear the community's thoughts :)

Those look like browser-compatibility fixes, mainly changing the user user agent to chrome on some websites. Or did I miss something?
This certainly is. Do you have a source?

Ask HN: Pricing for a security monitoring service for Linux servers/machines
Hi,

tl:dr; How much will you pay for a systems security monitoring service for Linux servers/machines?

I was having troubles keeping track of firewall rules/status, OS patch level for many Linux servers that I manage. I have built a simple solution around this problem, which offers

a. Tagging of machines
b. Firewall rule templates
c. Templates for packages and patch levels
d. Options for active alerting using webhooks
e. Configurable alert/warn thresholds customizable per user/tenant
f. Provision to push custom metrics to external stores (like Datadog/SignalFX/logstash etc)

This at present uses Saltstack, but it can be made to work with Ansible too. Has minimal UI (django,bootstrap,jquery); usability is decent as gathered from feedback by current users. Copyright is with me and I have plans to open-source this later. This solution can cover all Linux machines (servers, IoT devices, laptops, desktops) as long as they run a commonly used distro.

Due to a few issues on the personal front, I am exploring the option of quitting my full time job and spending more time with my family. And in order to make up for the loss in income from salary, I want to turn this solution into a SaaS business. But am not too sure if there will be any takers at all, hence this AskHN.

So, with the features listed above, if this SaaS solution is offered at a rate of $10 per host per month, would there be any takers for it? Is the market for this kind of a solution broad enough? At $10 per host per month, how long can it take to reach a revenue of $10000 per month?

Simply put, would you be happy paying $10 per host per month for something like this? Or if you think $10 per host per month is high, what do you feel is a decent price?

Thanks!
Why would they need to update browser.js to do something shady, they can just drop in a brand new binary that does whatever they want it to do and the vast majority of users would be none the wiser.

For clarity: The Apple Watch does have a built-in Alarm which will wake you by Vibrating on your wrist. If you've muted the watch (swipe up from the watch face and tap the Mute icon) then you won't get a corresponding alarm noise.

I like the suggestions for #1 and #2 though. Not sure how you'd track light vs REM sleep.

a. Accelerometer: As I understand it, people don't move at all when in REM sleep, but I don't think it follows that people are guaranteed to move often (or at all) during light sleep, so I'm not sure that the accelerometer could be used to determine that.
Source: http://www.brainfacts.org/about-neuroscience/ask-an-expert/a...

b. Pulse monitoring: Apparently pulse rate is steady during light sleep but variable during REM sleep or when awake. Again, I'm not sure that's enough to reliably determine things.

Perhaps combining the two?

TL;DR it's a special kind of solar panel that works better in low light conditions. Super cheap solar panels are around 11% efficient, average cells are around 18%, and these are around 29% efficient. So about a 50%-ish improvement.

It is a fascinating breakthrough, but unfortunately even if it was 100% efficient indoor solar cells would still be pretty useless. As a rule of thumb indoor illuminance is 200-1000 lux, vs outdoor illuminance up to 120,000 lux. A lux is slightly less than 1.5e-7 watts per centimeter. So for a 500 lux room (which I'd call pretty well lit) with one of these devices the size of a smartphone you'd be harvesting 1.5e-7w/cm2/lux500 lux7cm14cm0.29 efficiency = 0.00213 watts.

As cool as this breakthrough is, it's not going to get anywhere. Current solar-powered household devices (pretty much just calculators) don't really need 50% more power, and other household devices need many orders of magnitude more power.

Even if it was 100% efficient, it'd still be gathering less than a hundredth of a watt. That's not coming anywhere close to useful.
How is that relevant in any way to the topic at hand? It's just pure whataboutism.
The post seems to be more about evaluating alternatives to preprocessor-based solutions to common problems; even when alternatives exist, reasonable people can disagree about whether they're actually better, but I think most would agree that it would be nice to have a proper module system instead of using textual includes, or that the fact that macros cannot be namespaced and can lead to ODR violations is not awesome.

Anyway, the post ends saying

> With current C++(17), most of the preprocessor use can’t be replaced easily.

and I think we can all agree on that.
I second this. Been in the industry for many years now. Typical people you run into:

- People who are constantly looking for a new gig. They have a model, they have experience, but either they can't find the appropriate fund for their style, or they have a bad streak.

- People who can make money, but only in small size. Some guys I know sit and home and trade. Enough to pay themselves, but not enough to even get a fund job.

- People who were on the team or near some star trader. Amazing how many of those there are, and how little it rubs off.

On the whole I'd say don't believe the hype. It's very hard to get a seat, and hedge fund managers are not smarter at recruitment than tech people. So you'll spend a long time in that support style role, wondering whether you'll ever get to be the main guy.

> Can we agree that making JVMs smaller does not necessarily require Jigsaw, its JSP, or in fact anything that can meaningfully be described as a module system? Do we agree that splitting up the stdlib can have size and performance benefits without having to break the stuff Jigsaw breaks?

I don't think we can unless there's an implementation proposal that takes that approach?

Certainly I think it would be impractical to make the JVM smaller without having visibility restrictions that apply even to reflective access. To be able to develop applications/library intended to run against a smaller JVM I need a way to restrict myself from using certain features even when developing on a full-sized JVM.

I don't think these examples are necessarily bad conclusions. A team could have won a dozen games before this one, so in that case you'd bet on the team with a better record regardless of a fluke.

And depending on where you live, it may not be possible to reach an interview if you're delayed. I mean, transport networks have accidents, strikes, signal failures, delays and god knows what else, and the alternative route may be signficantly slower. In that case, it doesn't matter how good your timing is. You could have left an hour in case of problems and still end up late. At some point, you have to assume these things will work out 90% of the time and be willing to accept the loss the other 10%.

And the final example is pretty vague about what the step actually was. If the wrong step led to a five feet drop off a rock, then yes, the wrong step may well have been why they broke their ACL...

Yes, don't blame the world for all your mistakes and problems. But at the same time, accept that you're not responsible for every single thing that happens to you as well. No one can always be prepared for every possible situation, and that's just fine.

cough poor them.
This is a lot like the SAFE technique for crisis management. I was taught it in the context of wilderness survival (particularly when you get lost), and apparently it comes from kayaking.

1. Stop
2. Assess the situation
3. Formulate a plan
4. Execute

Repeat steps 2-4 as you progress. (I guess you could make it SAFER, and make R for Repeat).

I've found it very useful for general crisis management, especially for physical crises. Just forcing yourself through the steps makes you think of better options, rather than running off and making the problem worse.

I don't think it's such a good pattern for long term problems though, the idea is that you're reacting to your immediate situation and dealing accordingly, so it's effective for events that need immediate attention, such as car crashes, first aid situations, or getting lost in the wilderness.

That would apply if we were talking about a general in a war and his philosophy for dealing with his enemies. It might also be applicable to a metaphorical general in a metaphorical war, like when people use this quote when discussing competition in business. However if a public servant is thinking in these terms about his interactions with his own constituents and his colleagues after taking office, something is seriously wrong with that person. Running for office is a completely different activity than executing the responsibilities of that office after winning it.

When we're talking about not just a public servant, but arguably the public servant with more responsibility on his shoulders than any other human being in America if not the planet, the same principles apply a million times over.

I guess you could do it in space as long as you could have a sphere of molten glass floating, then immediately surround it with water from all sides.

My reasoning is that the tail is formed because the molten glass is dropped into the water, hence forming the tail. So if you could have a sphere and cool it down from all sides simultaneously then it should form a sphere based version.

Of course there's also a chance of explosion.

There is a difference between the engine I use to access a large variety of websites, and a single website/service.
I'm not offended by people playing "my" games - I'm offended by people who can't appreciate the amount of work which is channeled into making games. You can be certain that for every single feature within a (good) game, at least one person spent countless hours thinking about it.

You don't like a feature - that's totally fine. Talk about your grievances all you like, so we can learn and improve said feature. But don't call the people "lazy" if you don't know what you're talking about.
That's a bit of a false equivalence. Letting me do something while you watch is not the same as you stopping (and punishing) me from doing it right away. You can argue which one is worse from a moral perspective, but they are not the same.

As for the shitty foreign policy - if I had to buy only stuff produced in "ethical" countries, I'd be living naked and eating only dried fish.

In a larger sense, it's about persuading Joe Public that this activity is in any way useful.
But thinking US companies are different because they claim they're not working with the American surveillance state is mostly deluding one's self. If you ask them, Opera can also probably issue a statement saying that they don't let the Chinese surveillance state spy on them, if one says "I believe you" to one class of orgs, and "I don't believe you" to another class, and the difference is the race...

Obviously in the US there's more checks and balances, to make a company's statement more believable. Or that's what we believe anyway...
Nevertheless, it is a fund that has beaten the markets consistently. I was just saying that it is possible to do, so the entire industry is not the sham that most people think it to be. Just the vast majority of it is.
Subject to Chinese laws though.. although what gets enforced is a different matter.

It's the reason IE isn't the market leader. There's a good reason for it to want market share.

I don't particularly trust Moz://a, I just trust Firefox a butt-ton more than Chrome or Opera.
Funny for this to happen on the same week I switched my default browser from Firefox to Vivaldi [1]. That is really "Opera reborn", since it's built and owned by the original team of Opera developers - which is probably why it's so good.

2 New Studies Reveal the Dark Side of Workplace Flexibility
IMO a lot of the information in this article is suspect. Perhaps the terminology is different in the states, but decision makers tend not to be known as "traders" in the UK: they're portfolio managers. Traders are middle-office guys who handle execution. Secondly, there are very few shops that can charge two and twenty these days. Even in the good days, two and twenty was the 'sticker price', a point at which to begin fee negotiations. Any client with a decent-size ticket would pay less.

As a junior / mid-level front office hedgie I made £120k last year. I wouldn't be surprised if my boss made double that. Not a stunning amount, but easily enough to be comfortable and save for the future. Unless you're an equity partner at a hedge fund, that's what you can expect to earn in the uk.

The appeal of asset management is mostly about the lifestyle rather than the comp: interesting, varied work, with fifty hour weeks and no weekend work. On a per hour basis, you might do better than someone on the sell side, but those guys work a lot of hours.

HTML and CSS alone would not be adequate for the kind of behaviour you are looking for - 'updating their site'. At the very least, you need to learn how to customise a CMS. A well known CMS that I would recommend is WordPress. However, there are others in other languages/platforms. But, since you are talking of a CMS, I thought I should point you towards the most widely used one. Thus, you need to invest your time in learning how that CMS works and what you need to do to customise it for your clients. You might also need to learn something about databases and MySQL would also be another good recommendation.

"I have a really boring story about that revolving around a company that paid out severance gradually instead of lump sum"

Here in Japan, where I live, this is one of the reasons that people can't take all their accrued vacation, even when quitting their jobs. When you leave a job, your accrued days are paid out as if you were still working. So if your last day in the office is June 30, but you have 30 days saved, your last day as an employee is ~August 15.

This sometimes means you can't start your new job until after that, and because employers typically want people to start ASAP, people end up forfeiting the vacation time they never got to take while working. The new employer wants them on July 7, so they take just the one week and then start at the new place.

And given how hard it is to take time off, the typical employee has lots and lots of unused PTO. My workplace has a cap of 40 and I am always at the cap.

Maybe people value the current state of Bitcoin with its 'flaws' and all.

The Bitcoin-as-gold vision is the current de facto situation (vs Bitcoin as coffee payment system). The scaling issues are really a simplistic way to explain the conflict between this two visions (worth mentioning that the block size increase, another simplification, won't solve either in mid/long term)

Also, improving utility is subjective in this case.
Bitcoin is a not a product or service in the traditional way: it does not have to serve all the users, there's no clients as such, there's no companies to sell the 'product' to. Its roots are real financial disruption, not another payment network.

The inconsistency of OSM coverage from one place to another can be a bit baffling. While cycling around South Africa four years ago, I added quite a lot of detail to areas on the Garden Route. It’s a bit disappointing to look at the map and see that almost nothing has been done with these particular locations since then, even though it’s a heavily touristed area and a developed country where you’d think at least some locals would be interested in mapping. And yet, at the same time there are some rural areas around the world that seem out of the way, but they show continual improvements by successive visitors.
Opera ASA the company used to get its money by selling the browser, then moved to an ad supported browser (circa v5 IIRC), then they managed to secured enough funding through commercial partnership (mostly google to be the default search engine, same as firefox) and removed ads from the browser, another source of income source was opera mobile.

A few years back the founders got removed and there was a shift to quarterly profit and they stopped developing and maintaining their own rendering engine and browser to basically become a skin for google chrome, saving costs.
In the recent times they improved their skin status and tried to sell the whole package and managed to do last summer to a chinese consortium of investors.

I suppose right now opera gets its money from the deep pockets of rich chinese investors, the current business model might have something to do with surveillance capitalism.
