1,062,312 | I have Windows 10 build 10586.164 installed on my machine, and am trying to set up a Hyper-V test lab.
I find that after I restart my PC, I can add and change hardware without issue, but after a while, I start getting this kind of error when modifying hardware:

This seems to also happen when adding disks and things of that nature.
The events I see don't tell me much:

I have seen some people seeing the same issue with older version of Hyper-V, but their solutions don't work or don't apply.
Has anyone come across this in Windows 10 before and have any idea what may be causing this? Could it be a permissions or group membership thing? | 2016/04/06 | [

] | The exact behavior of shields varies through the canon. It's generally accepted that shields block high-energy transmissions (phasers, disruptors, transporter beams), and "high-velocity" physical objects (photon torpedoes, asteroids, even smaller ships). However, there are also instances of a ship's shields holding back powerful but slow-moving physical barriers, such as the gate into the Dyson's Sphere in the *TNG* episode "Relics". So, one would think with shields at full that a collision with a piece from another ship would leave the debris worse off than the shielded ship.
In addition to deflector *shields*, most Federation ships have a deflector *array*. This array is highly configurable, and so can do [basically anything the scriptwriters need](https://tvtropes.org/pmwiki/pmwiki.php/Main/EveryDeviceIsASwissArmyKnife), but its primary purpose is to push away large physical objects while the ship is underway; it's the ship's "icebreaker", shoving aside particulate matter, asteroids, etc while the ship is moving, especially at warp. It's supposed to work in much the same way as the full shields, but is generally lower-power in "shield" form, requiring a "beam" to push higher-mass objects. It's logical, given the difficulty involved in locking transporters on to a moving target, that the deflector array would simply be overwhelmed. The very large ship remnant that *Enterprise* specifically has to dodge is also half the size of the *Enterprise* herself; at some point the act of using any sort of beam to shove away a hunk half as heavy as yourself without any change in your direction or velocity would offend our Newtonian-oriented sensibilities.
The in-universe answer would probably be that the deflectors, both the full shields and the array, is simply overwhelmed by the sheer size and number of debris objects that must be shunted aside. Why they're still effective at near-full power after that, to absorb one of the *Narada*'s missiles, is anyone's guess. The out-of-universe answer is that it's more visually engaging to see a piece of flotsam the size of an aircraft carrier gouge out a few panels of the brand-new *Enterprise*'s saucer, with or without shields.

] | I don't believe there are canonical examples of starships plowing through fields of ship-sized debris and expecting the shields to handle it for them. Maybe this is just because captains prefer to preserve their shield power, but it's certainly plausible that shields just aren't meant to handle that sort of thing. | I've always attributed this to the *size* of the debris that collided with the ship. As you mentioned, the shields (augmented by the navigational deflector) are capable of deflecting interstellar dust, even at high velocities.
But dust has a relatively low mass, meaning the energy required to move it out of the way is not very high (relatively speaking). The destroyed starship debris on the other hand, IIRC, was a large section of a secondary hull, a piece of the saucer section. The energy required to deflect this would have been orders of magnitude greater. Also, we don't know what velocity the Enterprise was traveling at, whether it was moving at full impulse or some fraction. This would have played a large part in how effective the shields would have been as well.
Finally, remember back to the movie *Nemesis*. In the final battle the *Enterprise* is struck by a large section of a Romulan ship. It is not unreasonable to assume that the *Enterprise-E* from the 24th century, built to battle all the baddies of its age, would have had vastly superior shielding technology. Yet even with that advantage, the shields were only *just* able to deflect that piece of debris. |

18,123 | I fitted a new tap and waste outlet to a small basin, because the new outlet is shorter than the old, the plastic pipework no longer reaches (see photo) I can force the parts to mate but I don't like having the pipe under a lot of strain and it doesn't seal properly (I havent tried applying copious amounts of plumbers putty).
I am considering cutting off the white-painted down-pipe (at right of photo) and using a solvent-weld straight coupling to insert a new section of pipe to raise the pipework about 1 cm.
The existing pipe has an outside diameter of 36 mm.
The pipes available in catalogues are listed as 32 mm or 40 mm.
I understand that a nominal 32 mm plastic waste pipe has an outside diameter of 34.5 mm. Is this the right pipe? | 2012/09/16 | [

Cut where marked, but adjust the location so you've got clearance to work later.
Seeing as you only need a couple of millimeters, you might be able to get away with buying only the coupling connector similar to this:
So a good straight cut where marked, insert the connect and solvent weld it back into place.
Take the cut piece in with you, and just make sure you've got a snug dry fit in the store.
No need to actually figure out the exact diameter. Just buy the piece that fits. | So far I have discovered there are at least two incompatible types of "32mm" plastic waste pipe.
* "**solvent weld**" PVC or ABS pipe with an inside diameter of **32mm** and outside diameter of **~37mm**.
* "**push fit**" plastic pipe with an inside diameter of **~29mm** and an outside diameter of **~35mm**
Because of the difference in diameters, you can't use push-fit fittings on "solvent weld" pipe and you can't use solvent-weld fittings on push-fit pipe. I guess this is deliberate to stop people trying to use solvent to weld a pipe made of a material that the solvent won't melt.
Diameters above are approximate measurements made with a cheap vernier gauge. |

Very useful. *As a murder witness*, the detective's testimony can be more useful than the average witness's because the detective's training renders him capable of paying attention to important elements that to the average witness tend to go unnoticed.
Outside the *murder witness capacity*, your description oversimplifies the detective's role in an investigation. The detective is more than a clerk who takes notes and delivers items to a facility. His scrutiny of the evidence can highlight to the fact-finder a number of inconsistencies and nuances that are far-reaching, more relevant than "*I talked to some people*" and "*I wrote some reports*". | >
> ... everything the detective learns is hearsay ...

[Hearsay](https://en.wikipedia.org/wiki/Hearsay) doesn't mean what you think it means.
Under the Federal Rule of Evidence (which is representative of all common law jurisdictions): "Hearsay is a statement, other than one made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth of the matter asserted."
So the lead detective (or anyone else) can testify about their own experiences: what they saw, what they heard, what they felt (physically and emotionally) and that is evidence of the truth of those experiences. This includes testimony about things that were said *to them* as proof that those things were said but **not** that the things that were said are themselves true.
An example may help. I'm the detective and I interview you. During that interview you say to me "I heard a gunshot." I can testify that you said you heard a gunshot - that is evidence that you said it, not evidence that a gunshot was actually heard. This might be relevant if, for some reason, your testimony in court is now that you *didn't* hear a gunshot.
Naturally, all the physical evidence that the detective sees or collects is not hearsay because it was the detective who did the seeing and collecting. Similarly, the detective's evidence on who was where, when, what they were wearing, whether they were covered in blood etc. is not hearsay.
Furthermore, there are a bunch of exceptions to the hearsay rule. The most significant is that inculpatory statements by a defendant are **not** hearsay. If a suspect says "I hit him with a brick" to a witness and that suspect is on trial in a murder where the physical evidence indicates the victim died after being hit with a brick, that statement is admissible as evidence that the defendant "hit him with a brick". |

305,245 | I have a device I designed which utilizes 32 SK6812 LEDs (RGBW neopixels).
I am experiencing noise in the 1.2khz range (SK6812 LEDs use a 1.2khz PWM signal to control color and brightness) and its associated harmonic frequencies. This noise is most apparent in the 5v line on my device (the SK6812 LEDs are powered on this line).
The device is powered by a modular rack which has +12v, Ground , -12v. The 5v power for the SK6812 is supplied by a switched power supply that drops +12v to 5v5, which goes through an LDO and then to the 5v line where the SK6812s are connected.
The noise is apparent on other modules connected to the same power rails. These are mostly analog audio modules, and when they are completely silent, when the gain is boosted 65db, the noise becomes apparent.
Here is a photo of the spectrum of the noise recorded:

Here is a photo of the spectrum of the rack with my device disconnected completely:[](https://i.stack.imgur.com/tMu5Z.png)
I am pretty certain that this noise is coming from the LEDs because (1)the noise is only apparent when the LEDs are on, and changes slightly when different LEDs change color, and (2) because most of the noise heard is at the same frequency as the PWM rate for the LEDs.
One obvious solution is to increase bypass capacitors, and possibly use higher capacitance aluminum electrolytic in addition to my 0.1uF ceramic capacitors
My questions are these:
1) What value (and type) of capacitor do you recommend to lower low frequency noise in the 1khz - 5khz range? With 30 LEDs, how many would you reccomend?
2) are there any clever (and cheap) ways to isolate my device completely where it connects to the rails? Ferrite Beads? Inductors? What type do you reccomend?
3) I plan on moving to a solid ground plane (I am currently using a hatched - which I recently found out doesn't help) as well as adding a ground plane to the top layer (2 layer board). Do you think adding additional copper on ground might help the bypass capacitors work better?
4) Anything else I am forgetting to ask?
Thank you!

] | That is the nature of these neopixel devices. They have no output inductance or capacitance on the PWM switching. They generate a lot of EMI.
With a PWM frequency of 1.2Khz, the 1.2khz noise you are experiencing is expected.
It would be best if the 5.5 switcher, 5v LDO, and LEDs had their own ground plane.
Follow the PCB layout and decoupling guidelines to reduce conducted EMI.
This [Vishay Engineering Note](https://www.vishay.com/docs/ilb_ilbb_enote.pdf) covers them well.
Insert an input filter on the 12V line in to the switcher.
This is the EMI filter TI recommends on the Vin on their TPS92511 LED driver to suppress conducted EMI. For frequency between 1.2khz and 2.4khz the values would be around 10µH and 68µF.

The problem appears to be **load regulation noise ,** which does not follow the SMPS loop bandwidth or the slope of a capacitor.
**What is your peak current and supply current rating?**.
An answer is forthcoming but some obvious reduction of conducted noise is needed of "digital" LED noise and Analog supply. This means the source impedance of the supply including wire causes voltage spikes from pulsing the LEDs with ~1.2kHz PWM and some 20Hz causes yet to be defined.
The usual fixes are;
* isolated wiring directly from DC output to each load, analog and digital, so there is no current sharing and thus no drop on the power and ground for analog along the digital power wires.
* for audio. use low ESR cap 100uF Tantalum with a small series R with 100mV drop max.
* Use better quality regulator with low ESR caps in your 5 V supply.

Ability checks and saving throws are different things.
>
> Also, choose one ability. The target has disadvantage on ability checks with the chosen ability. (PHB, p. 251)

Not casting *hex*, since it isn't helping you, removes the worry about being invisible for that strike so that your hit can be a critical hit.
Surprise is ruled by the DM in any case ([see the question here](https://rpg.stackexchange.com/q/124807/22566)), but you have set it up so that you should surprise the target; you'll have advantage if you strike first. The key element here is setting it up so that "the target has not taken its turn yet" as a precursor to the strike. (Assassinate; 3rd level rogue assassin ability; PHB p. 97).
The DM will likely call for a Dexterity (Stealth) ability check as you set this up; success *should* set up surprise. While *invisibility* should make you unseen (unless the target has *true sight*, or a similar ability) you still need to be undetected by hearing, and possibly by smell. Both of those senses are mentioned in some monster stat blocks as providing advantage on Wisdom(Perception) checks.
*Is the enemy surprised even though I used hex before my attack?*
Solved, see above.
*Is there anything wrong with this order of events?*
Hex won't help you.
*Is my calculation also correct?*
You appear to have multiplied it by two, twice. Since serpent venom can be saved against, you don't double that.
If the target misses its Constitution save, your numbers are correct (except for the doubling of poison) from the death strike ability. The target may make the save, since the dice can be fickle.
If the target does not make their constitution save versus the 17th level ability:
(2d6 hex + 18d6 sneak attack + 6d8 fire + 5 dex modifier + 2d8 rapier)\*2 + 3d6 poison (half for save).
But, see below, I think the case can be made that the poison damage goes inside the parens.
Aside: whether or not two saves have to be rolled, or one, since both are Con saves, is an interesting question. I'd recommend separate saves since two different mechanics are in operation here.
---
Do we double the poison delivered by Death Strike? I argue yes.
An argument can be made for folding the 3d6 (half for save) inside the parens since it is part of the whole attack; Death Strike isn't a critical hit, but is rather a unique rogue / assassin ability. That would resolve the damage as:
(2d6 hex + 18d6 sneak attack + 6d8 fire + 5 dex modifier + 2d8 rapier + 3d6(half for save)\*2.
I believe that this is consistent with the rules text for Death Strike as compared to rules text for Critical Hit.
Poison is usually treated as separate from weapon damage dice on attacks, and crits, in terms of what dice are dice rolled for doubled damage. Since poison involves a saving throw effect, [it doesn't look like doubling the dice fits in that order of operations](https://twitter.com/JeremyECrawford/status/536683487517224961) for a critical hit.
>
> Q: If you crit with a poison coated weapon, do you double poison dice because crit, or not because saving throw?
>
> A: The intent is no. The saving throw, not the attack, determines whether the poison takes effect after a hit.

>
I'll offer that this *ruling* need not apply to Death Strike. Injury poison (in which class serpent venom falls), does some damage on any hit, dice are rolled for damage, and it does full damage on a failed save. (DMG p. 258)
The problem with ruling the poison outside the parens Death Strike is that Death Strike isn't explicitly a critical hit; it is a class feature contingent upon a save made by the target, like a "save or suck" effect along the lines of Disintegrate or Banishment. Doubling the damage of the poison (placing that 3d6 inside the parens) on the Death Strike is consistent with the text of that rule.
Since Death Strike is a different mechanic than critical hit, it does not have to follow critical hit's rules. (Crits don't allow for a save, crits don't fold in ability modifier, and per Crawford above, crits don't fold in poison damage ... ).
>
> On a failed save, double the damage of your attack against the creature. (PHB, p. 97)
>
>

So double it all.
My reasoning is that the rogue's attack resolved by Assassinate, if surprise is achieved, ends up like this:
(2d6 hex + 18d6 sneak attack + 6d8 fire + 5 dex modifier + 2d8 rapier + 3d6(half for save).
On a failed save versus Death Strike, you double that, since it doesn't say you roll extra dice, but it says *double the damage*. It doesn't make exclusions the way that critical hit does. Critical hit says ...
>
> When you score a critical hit, you get to re-roll extra damage dice
> for the attacks damage against the target. ... and then add your relevant ability modifier(PHB p. 196)
>
>
>
(2d6 hex + 18d6 sneak attack + 6d8 fire + 5 dex modifier + 2d8 rapier + 3d6(half for save)\*2 is "double the damage" literally.
Based on the ruling cited, I can see the argument against this being that "poison" is making its own attack to be saved against. What the assassin rogue is doing is providing a way for the poison to do it's thing; for serpent venom you need to do piercing or slashing damage to let it work. (DMG p. 258) While that's the general rule, and the ruling fits for most situations, I'll offer that Death Strike is a *Specific beats General* (PHB, p. 7) case of doubling all of the attack's damage, based on how the text is presented. | ### Apply serpent venom poison to rapier
From [serpent venom poison](https://www.dndbeyond.com/equipment/serpent-venom-injury) description:
>
> This poison must be harvested from a dead or incapacitated giant poisonous snake. A creature subjected to this poison must succeed on a DC 11 Constitution **saving throw**, taking 10 (**3d6**) poison damage on a failed save, or half as much damage on a successful one.
>
>
>
Damage caused by saving throws [is not doubled on a critical hit](https://twitter.com/JeremyECrawford/status/536683487517224961). At least not RAI.
### Casts *Hex*...so the enemy gets a disadvantage on constitution saving throws
*Hex* applies disadvantage on target's **ability checks**, not **saving throws**.
### Sneaks to target...
### or *Is the enemy surprised even though I used Hex before my attack?*
Per Surprise rules:
>
> The GM determines who might be surprised. If neither side tries to be stealthy, they automatically notice each other. Otherwise, the GM compares the Dexterity (Stealth) checks of anyone hiding with the passive Wisdom (Perception) score of each creature on the opposing side. Any character or monster that doesn't notice a threat is surprised at the start of the encounter.
>
> If you're surprised, you can't move or take an action on your first turn of the combat, and you can't take a reaction until that **turn** ends. A member of a group can be surprised even if the other members aren't.
>
>
>
Once you start a combat, everybody rolls initiative, **regardless if they're surprised or not**.
On your turn you can cast both *Green-Flame Blade* and *Hex*. Nothing wrong here.
### The biggest issue of all, if your opponent is still surprised.
Once his turn ends, he is no longer surprised, so you must have higher initiative roll than he has.
---
### Is warlock even that necessary?
Think of it, you can substitute 3 levels of warlock and go full rogue.
**Cons:**
* No magic (including the most powerful cantrip *Eldritch Blast* and 1d6 from *Hex* and 4d8 from *Green-flame Blade*)
* Loss of invocations
**Pros:**
* Additional 1d6 from Sneak Attack
* *Elusive* (no advantage on attacks against you!)
* Additional ASI (how about +5 to initiative feat, so you definetely surprise your enemies?)
* *Stroke of Luck* (turn a miss into a hit or take 20 on failed ability check)
Additionaly you can take High Elf and simply choose *Green-flame Blade* as your desired cantrip. |

] | There are basically 3 "standard solutions":
*Solution 1*
You need the product (like in your case because of the invoices referencing it). This means the data is VALID and the only change is that it goes "out of stock" or "out of portfolio". In any case your business process often will need you to handle RMA situations or some IRS related matters for example... this means the product must not be deleted. This is just a different "state" of the product which needs to be reflected by your DB data model etc.
IF you are concerned with performance do some profiling... if need be you have a multitude of optimization options... these are usually RDBMS-dependent, one technique being "partitioning" - every RDBMS has its own mechanics which differ in flexibility etc.
*Solution 2*
You don't need any of the data at all... just do a cascaded delete and be done with it...
*Solution 3*
You only need historical data but no "future business process" will ever need this entity (i.e. product) again... in this case a common solution is to have archive tables which are filled before doing a cascaeded delete on the "active/productive tables". A slight variant of this scheme is copying the needed information into the "dependent rows" (invoice in your case) and just delete the active/productive row (i.e. product in your case).
*Conclusion*
Complex systems deal with a lot of different business processes/use cases and thus tend to employ all of the above techniques - each has its place depeding on the specific business processes/use cases involved... | Here is an answer I received from an un-named source. I will say this, he is pretty well respected, and to be respectful I am not going to post his name.
I am not going to accept my own answer here, or bypass the bounty, but am just showing his answer.
"With a full-featured RDBMS you can partition the table on the "deleted\_or\_not" column and that will result in all of the live production rows to be stored compactly. If you don't want deprecated data to show up in reports, simply give the full table an obscure name, such as customers\_including\_deleted\_rows and create a view "customers" (containing only the live rows) from which most of the application code queries. This assumes, of course, that there is some value to having the old data around." |

] | Ernst Mach and Julian Barbour suggest that *time is our perception of change*, and perhaps that's one of the best definitions of time I've found. The only physical fact lying under such definition is *change*, which we can perceive subjectively.
Before answering your question, a mental experiment. Imagine you are a prisoner in a jail cell where you cannot perceive change, at all. No prisoners near, no windows, no signals, noises, visits, nothing. Evidently, in such circumstance you will quickly start losing the sense of time. We need change perception to be aware of time.
In such experiment, you have anyhow some change perception. You can feel your heart beating, your respiration has a rhythm, your body functions follow a period. Using such information, you have a minimal perception of change that allows you to get a minimal notion of time. In ultimate instance, you can count lambs.
But in your experiment, there are only two events (or one). That is equivalent to say that there's no perception of body functions, of respiration, of nothing. Not even labs counting. Cerebral death. The two events can be considered to waking up twice, for small instants, in the middle of the night, not knowing which is which.
Under such light, your question have two possible answers:
* "nothing happens", and "time still pass". That is equivalent to say that even if nobody hears it, there was a noise.
* "nothing happens", and time does not pass. That is equivalent to say that if nobody hears it, there was **no** noise.
So, from this perspective, your question would be highly biased by preconceived ideas about perception. If the existence of the time entity is subjectively dependent, the idea of modifying the perceptive conditions would only have a rhetoric impact, since we cannot modify our perception to such extreme. | Time, as we know it is a method of tracking events, the "time" we know is something that is defined by man, but something defined by man is not always created by them, "time" will always flow, without time, we would not be able to see, hear, think, thus be.

No prisoners near, no windows, no signals, noises, visits, nothing. Evidently, in such circumstance you will quickly start losing the sense of time. We need change perception to be aware of time.
In such experiment, you have anyhow some change perception. You can feel your heart beating, your respiration has a rhythm, your body functions follow a period. Using such information, you have a minimal perception of change that allows you to get a minimal notion of time. In ultimate instance, you can count lambs.
But in your experiment, there are only two events (or one). That is equivalent to say that there's no perception of body functions, of respiration, of nothing. Not even labs counting. Cerebral death. The two events can be considered to waking up twice, for small instants, in the middle of the night, not knowing which is which.
Under such light, your question have two possible answers:
* "nothing happens", and "time still pass". That is equivalent to say that even if nobody hears it, there was a noise.
* "nothing happens", and time does not pass. That is equivalent to say that if nobody hears it, there was **no** noise.
So, from this perspective, your question would be highly biased by preconceived ideas about perception. If the existence of the time entity is subjectively dependent, the idea of modifying the perceptive conditions would only have a rhetoric impact, since we cannot modify our perception to such extreme. | I don't think we can acknowledge the possibility that nothing happens in any physical universe without positing complete uniformity, having maximal entropy. Furthermore, I think there are cosmological and metaphysical issues with such a universe, not the least because it requires a very substantive infinite quantity.
Possibly the question is placed regarding a physical universe containing exactly nothing. But this doesn't allow event A to take place, provided that A is defined physically.
Given that the premise of the question is implausible, I would say it's not necessary to address the specific question of whether time passes. |

11,859 | In the early stage, it's said that radiating loving kindness to opposite sex can potentially arouse lust.

] | * **Lovingkindness**, good-will (metta): **Near enemy** – **attachment/lust**; far enemy – hatred
* Compassion (karuna): Near enemy – pity; far enemy – cruelty
* Sympathetic joy, Appreciation (mudita), joy at the good fortune of
others: Near enemy – comparison,hypocrisy, insincerity, joy for
others but tinged with identification (my team, my child); far enemy
– envy
* Equanimity (upekkha): Near enemy – indifference; far enemy – anxiety, greed
Practicing loving kindness towards the opposite sex does not increase attachment or arouse lust. But if you are a lustful person, you can easily mistake the counterfeit near enemy as the loving kindness and as a result arouse lust and increase attachment in you.
So if you have an urge to make physical contact with someone or chat up and winover, you should avoid practicing loving kindness towards them until you are skilled enough to identify the counterfeit from authentic Metta. | Generally you should not do Metta to:
* Lingavisabhāga (opposite sex - generally directed at a specific person)
* Kālakatapuggala (a dead person)

**What is the proper way to do this?**
If you are generally spreading Metta as say "May all women be well and happy" then it is fine.
**In the early stage, it's said that radiating loving kindness to opposite sex can potentially arouse lust. While I'm not sure if the person who we radiate loving kindness to can have their lust aroused, is radiating loving kindness in any stage of practice by any means can increase the attachment to that person?**
This is the reason you should not do it directed at a specific person of the opposite sex. This can lead to lust and attachment.

As far as impact, it's a cost to upgrade so businesses need to evaluate whether or not to upgrade. Many companies have realized that newer machines come with win 7 licenses so there is no upgrade price. | Just some further information, many vendors only provide support for their products when they are used in a supported environment. For example JoeAccounting is the software your accounting department uses on their Windows XP computers. Say something happens and you have to re-install JoeAccounting on their computers, but you run into an issue. Right now you can call JoeAccounting support and they can help you solve the problem, in a few days from now if their policy is to only support their product on operating systems that are in support from their own vendor, then they will not be able to help you with the issue.
Many vendors utilize this policy and for good reason. If the source of the issue is something with the operating system itself, the vendor can work with the OS vendor to resolve the issue. If the OS isn't supported they can't do that.
If you are still running XP machines its not too late to upgrade, but to be honest even though the out of pocket is less to just buy Windows 7 and install it on the XP computers, it is better in the long run to buy new computers, a $1000 computer would pay itself off with increased productivity and decreased support cost in a year. Its very important even for small businesses to have life cycle's on their IT hardware and software. If you still have XP machines odds are they are 4 or more years old and that old in the business world for a computer. |

Microsoft will still allow you to update XP with any patches it has released up to the date that support officially stops.
*"This means that after the 8th April 2014, you'll still be able to use Windows Update to download all existing security patches.
This is important, as if you re-install Windows XP, you should still apply all of the existing patches in order to make the base operating system as secure as it should be."*([1](http://www.expertreviews.co.uk/software/1304965/when-windows-xp-support-ends-this-is-how-you-secure-your-pc-and-save-all-updates))
The important thing here is to at least get all your existing XP computers patched properly, which should have been happening all along. Don't get hacked with an exploit that came out 2 years ago!
if you are willing to pony up the money, Microsoft does offer "CUSTOM SUPPORT" to companies/governments/etc. willing to pay for it. The price isn't set in stone though, and is pretty exorbitant:
*"Microsoft understands that local laws, market conditions, and support requirements differ around the world and differ by industry sector. Therefore, Microsoft offers custom support relationships that go beyond the Extended Support phase.

Greatly increased isn't a hard/fast metric. To say it will increase 10%, 20%, 150%, is hard to say. The potential is definitely there for exploits to surface for XP that MS could have the ability to patch but won't after EOL.
However, there are ways to lower the threat risk and help ensure you are safe.([1](http://www.expertreviews.co.uk/software/1304965/when-windows-xp-support-ends-this-is-how-you-secure-your-pc-and-save-all-updates))
1. Make sure you have a good antivirus program, hopefully one with a decent malware scanner as well. The choices are numerous, so I'll leave that choice up to you.
2. Make sure all your software is patched and up to date. It can easily be a software exploit and not an OS exploit that allows for viruses/hacks to occur. Realize though that 3rd party software often won't be patched like an OS will, and worse they will often come back and say "you're still on XP? Our current version isn't compatible with XP now, you'll need to buy an upgrade."
3. Secure your web browsing as much as possible. This means knowing what sites you are accessing, using web content filtering if possible, using an A/V program that helps scan for issues while you are browsing, and disabling Java and other scripts from running if possible. Switch to Chrome or Firefox if possible, since IE for XP is dated at this point.
4. Be sure you aren't running with an administrative level account. This is good practice regardless of OS, but especially so after losing the ability to have security updates/patches for any new threats that arise.
5. Stop using Office 2003 and Outlook Express, which also will no longer be receiving updates/patches.
6. Upgrade to Windows 7 and use XP Mode for those stingy old apps that refuse to be updated.
Other choices independent of XP that are good security practices regardless of OS also prevail here:
1. Use both the desktop/client firewall and a "real" firewall(s) within your network, especially at the edge.
2. Use an IPS/IDS if possible
3. Keep detailed logs of network activity. Look for suspicious activity ESPECIALLY once an exploit becomes mainstream and starts making tech and news headlines.
4. Prevent installs of 3rd party software IT doesn't trust. Don't allow your users to install anything they desire (again better stated than implemented).
5. Keep your servers secure as possible. While an infected XP PC is bad, and hundreds of infected XP machines is worse...don't make it paramount by getting your servers infected/exploited by not securing them properly from virus propagation, etc.
6. Make sure your wireless and wired network is secure. This means not letting that employee bring in their "personal laptop" running XP with no service packs or a/v onto the network. If you are allowing such things, then all of the above is worthless. Same goes for VPN connectivity from home, USB sticks, etc. Make sure you know what you are letting onto the network.
**FINALLY, is there an answer to really make sure you sleep well at night?** Sure, it's called "UPGRADE FROM XP". While that may be a daunting task/project to undertake, realize that you aren't alone in this and that everyone else that has waited this long is undertaking the same project. Work through the issues specific to your company, draw up a plan of attack, and implement. There will obviously be costs involved as well as politics and user/culture paradigms, and if management simply decides to hold off even longer there's not much IT can do to force their hand other than list out why it is a bad idea to continue putting it off. There isn't a "one size fits all" approach here and if your company is still running a majority of XP workstations without a migration project already underway then it is likely there hasn't been much regards in terms of lifecycles/best practices/etc. regardless.

Microsoft will still allow you to update XP with any patches it has released up to the date that support officially stops.
*"This means that after the 8th April 2014, you'll still be able to use Windows Update to download all existing security patches.
This is important, as if you re-install Windows XP, you should still apply all of the existing patches in order to make the base operating system as secure as it should be."*([1](http://www.expertreviews.co.uk/software/1304965/when-windows-xp-support-ends-this-is-how-you-secure-your-pc-and-save-all-updates))
The important thing here is to at least get all your existing XP computers patched properly, which should have been happening all along. Don't get hacked with an exploit that came out 2 years ago!
if you are willing to pony up the money, Microsoft does offer "CUSTOM SUPPORT" to companies/governments/etc. willing to pay for it. The price isn't set in stone though, and is pretty exorbitant:
*"Microsoft understands that local laws, market conditions, and support requirements differ around the world and differ by industry sector. Therefore, Microsoft offers custom support relationships that go beyond the Extended Support phase. These custom support relationships may include assisted support and hotfix support, and may extend beyond 10 years from the date a product becomes generally available. Strategic Microsoft partners may also offer support beyond the Extended Support phase. Customers and partners can contact their account team or their local Microsoft representative for more information."*[2](http://support.microsoft.com/gp/lifepolicy)

Greatly increased isn't a hard/fast metric. To say it will increase 10%, 20%, 150%, is hard to say. The potential is definitely there for exploits to surface for XP that MS could have the ability to patch but won't after EOL.
However, there are ways to lower the threat risk and help ensure you are safe.([1](http://www.expertreviews.co.uk/software/1304965/when-windows-xp-support-ends-this-is-how-you-secure-your-pc-and-save-all-updates))
1. Make sure you have a good antivirus program, hopefully one with a decent malware scanner as well. The choices are numerous, so I'll leave that choice up to you.
2. Make sure all your software is patched and up to date. It can easily be a software exploit and not an OS exploit that allows for viruses/hacks to occur. Realize though that 3rd party software often won't be patched like an OS will, and worse they will often come back and say "you're still on XP? Our current version isn't compatible with XP now, you'll need to buy an upgrade."
3. Secure your web browsing as much as possible. This means knowing what sites you are accessing, using web content filtering if possible, using an A/V program that helps scan for issues while you are browsing, and disabling Java and other scripts from running if possible. Switch to Chrome or Firefox if possible, since IE for XP is dated at this point.
4. Be sure you aren't running with an administrative level account. This is good practice regardless of OS, but especially so after losing the ability to have security updates/patches for any new threats that arise.
5. Stop using Office 2003 and Outlook Express, which also will no longer be receiving updates/patches.
6. Upgrade to Windows 7 and use XP Mode for those stingy old apps that refuse to be updated.
Other choices independent of XP that are good security practices regardless of OS also prevail here:
1. Use both the desktop/client firewall and a "real" firewall(s) within your network, especially at the edge.
2. Use an IPS/IDS if possible
3. Keep detailed logs of network activity. Look for suspicious activity ESPECIALLY once an exploit becomes mainstream and starts making tech and news headlines.
4. Prevent installs of 3rd party software IT doesn't trust. Don't allow your users to install anything they desire (again better stated than implemented).
5. Keep your servers secure as possible. While an infected XP PC is bad, and hundreds of infected XP machines is worse...don't make it paramount by getting your servers infected/exploited by not securing them properly from virus propagation, etc.
6. Make sure your wireless and wired network is secure. This means not letting that employee bring in their "personal laptop" running XP with no service packs or a/v onto the network. If you are allowing such things, then all of the above is worthless. Same goes for VPN connectivity from home, USB sticks, etc. Make sure you know what you are letting onto the network.
**FINALLY, is there an answer to really make sure you sleep well at night?** Sure, it's called "UPGRADE FROM XP". While that may be a daunting task/project to undertake, realize that you aren't alone in this and that everyone else that has waited this long is undertaking the same project. Work through the issues specific to your company, draw up a plan of attack, and implement. There will obviously be costs involved as well as politics and user/culture paradigms, and if management simply decides to hold off even longer there's not much IT can do to force their hand other than list out why it is a bad idea to continue putting it off. There isn't a "one size fits all" approach here and if your company is still running a majority of XP workstations without a migration project already underway then it is likely there hasn't been much regards in terms of lifecycles/best practices/etc. regardless.

> | Just some further information, many vendors only provide support for their products when they are used in a supported environment. For example JoeAccounting is the software your accounting department uses on their Windows XP computers. Say something happens and you have to re-install JoeAccounting on their computers, but you run into an issue. Right now you can call JoeAccounting support and they can help you solve the problem, in a few days from now if their policy is to only support their product on operating systems that are in support from their own vendor, then they will not be able to help you with the issue.
Many vendors utilize this policy and for good reason. If the source of the issue is something with the operating system itself, the vendor can work with the OS vendor to resolve the issue. If the OS isn't supported they can't do that.
If you are still running XP machines its not too late to upgrade, but to be honest even though the out of pocket is less to just buy Windows 7 and install it on the XP computers, it is better in the long run to buy new computers, a $1000 computer would pay itself off with increased productivity and decreased support cost in a year. Its very important even for small businesses to have life cycle's on their IT hardware and software. If you still have XP machines odds are they are 4 or more years old and that old in the business world for a computer. |

115,074 | Is there an instrument that can produce a sub bass sine wave like tone, that also has a lot of volume? Something that would sound a bit like an 808 bass.
I've listened to some contrabass type flutes but it sounds very breathy and there are too many overtone sounds.
I know that an ocarina produces a tone that comes close to a sine wave. Here is an example of a giant bass ocarina which comes close, but sounds a bit soft and underwhelming. | 2021/06/07 | [

] | There really is no such thing as a sub bass sine like tone with a lot of volume. There are some organs with 32" subbass flutes (which produce a comparatively sine-like tone). They are monstrous in size and move a lot of air, but due to the limits of human hearing, the audible volume is not all that large. You feel their effect a lot more than you hear it.
It's one reason that motor bass/subbass speakers have been prohibited for concert use: they don't have a lower frequency limit like cone speakers, and people exposing themselves to excessive subbass noise have actually died of spleen rupture.
So the closer you get to your "sine wave" ideal, the more certain it is that you'll find the results "a bit soft and underwhelming". Actually "strong" bass instruments almost invariably have significant amounts of overtones. And since it is the overtone interaction that makes for the bass functioning as a harmonic foundation, really low sine tones tend to be harmonically arbitrary: if you are off by a tone or so, it doesn't really register all that much in terms of being disharmonious. | What do you mean by sub bass? Are you referring to a sub harmonic of the instrument?
I will assume you are asking whether an instrument can produce a pure sine wave.
It would be very unlikely to get a pure sine wave from a musical instrument. Even a function generator will produce transient harmonics due to being "switched on". Without getting into the details of the math and physics, the specific harmonic spectrum of the instrument depends on (1) what overtones are supported by the physics of the instrument construction and (2) how the instrument is attacked, or how sound is excited in the instrument. Additionally, the harmonic spectrum can depend on time. It may be bright at first then decay, leaving mostly the fundamental (which would be as close as possible to a pure sine wave). The guitar and other plucked instruments have this property.
If you pluck a guitar string close to the center you excite more fundamental but you still do not have a pure sine wave. I would say that it is very unlikely that any instrument and player could produce this. At the very least there would be harmonics for a short time due to starting the sound.
As a side note, the human ear is non-linear and creates aural harmonics. So, even if you use a function generator as an input the signal to the brain will be "corrupted" with harmonics.
If you are referring to an instrument producing a true sub-harmonic. I is possible but most so called examples of a sub-harmonic are false. They are the result of changing boundary conditions in the attack and people completely misunderstand the physics of what's going on. |

] | You might need to have a talk with your DM. Ask him why he keeps using these kinds of monsters. Remind him that you are here to kill things and take their stuff. :) This kind of tactic, used right, could be an interesting twist in the game. Having to track down and finally kill an annoying bad guy is very rewarding. If every critter does it, it loses its appeal very quickly IMHO.
That said, what monsters is he using? Teleporting away from the battle isn't an ability given to stock monsters (that I'm aware of).
I checked the Compendium and found some teleport 8's and a teleport 10 (Bahumut[DDI](http://www.wizards.com/dndinsider/compendium/monster.aspx?id=4218)) but I'm not aware of any critters can teleport far enough away to get out of battle. If the monsters are just using teleport to get a head start on running away, in addition to the fine suggestions already given, I'd suggest reconfiguring a character or two to become a chase character. A Barbarian or an Avenger can cover a lot of ground quickly in pursuit of a target. I'm sure other characters can do the same with the right feat/power choices.
One additional thing, teleportation can only be used to destination squares that you have Line of Sight to. The DM should not be teleporting[DDI](http://www.wizards.com/dndinsider/compendium/glossary.aspx?id=321) critters through walls or into closed off rooms.
If the DM breaks the rules once in a while in an attempt to make the game his own, I'm fine with that. But if he is redefining basic terms like teleportation, then you have a right to know the exact definition that he is using along with any limitations. | It's possible the DM is just enjoying a power trip, in which case there's nothing you can do to fix this situation at the *technical level*. As other answers suggest, you need to sit down with your DM and figure out why this is happening at the *social level*.
But that aside...
**Let the DM teleport his monsters away.**
1. You get full XP for these encounters.
2. You got to finish the encounter quicker.
3. This means you get more encounters per session.
4. This means you level faster.
5. This means less risk to your characters!
If your DM isn't awarding the XP, he's ~~being a pain in the~~ not following the rules as written.
If the same nasty monster returns to attack you again, try to Intimidate it into leaving you alone. I think you deserve a check *before it's bloodied* and at least a small bonus to your checks for having defeated the monster before.

58,407,978 | I'm reading an article on Apache Spark and I came across the following sentence:
"Hadoop as a big data processing technology has been around for 10 years and has proven to be the solution of choice for processing large data sets. MapReduce is a great solution for one-pass computations, but not very efficient for use cases that require multi-pass computations and algorithms." ([Full article](https://www.infoq.com/articles/apache-spark-introduction/))
Searching the web yields results about the difference between one-pass and multi-pass compilers (For instance, see [This SO question](https://stackoverflow.com/questions/35673818/difference-between-one-pass-and-multi-pass-compilers))
However, I'm not really sure if the answer also applies for data processing. Can somebody explain me what one-pass computation and multi-pass computation is, and why the latter is better, and thus is used in Spark? | 2019/10/16 | [

That is, first the mapper job runs, spits out the mapping files, then the reducer job starts. At every stage the job requires resource allocation. Therefore, a single map-reduce job required multiple iterations. If you have multiple map phases, after every map the data needs to spit out to disk before other map task starts. This is the **multi-step** process.

Spark
=====
On the other hand, spark does the resource negotiation only once. Once the negotiation is completed, it spawns all the executors and that stays throughout the tenure of the job.
During the execution, spark doesn't write the intermediate output of the Map phases to the disk, rather keeps in memory. Therefore, all the map operations can happen back to back without writing to disk or spawning new executors. This is the single step process.

Apache Spark processing framework allows you to read data once which is then cached into memory and then we can perform multi pass computations on the data. These computations can be done on the dataset very quickly because the data is present into memory of the machine and apache spark does not need to read the data again from the disk which helps us to save lot of input output operations time. As per the definition of apache spark it is an in memory processing framework which means the data and transformation on which the computation is done is present in memory itself. |
4,552 | I'm a complete newbie to woodwork - please bear with me!
I'm trying to build a free-standing fence or barrier that will sit on top of concrete similar to this picture:
[](https://i.stack.imgur.com/3utB1.jpg)
The fence I want to build is a bit taller - 6-8ft. How wide does the "feet" of the fence have to be to keep it from falling over in the wind? I'm thinking about putting support braces in the photo like the picture - do they have to be on both sides of the fence and what size and height does the brace have to be? | 2016/08/23 | [

There are too many unknown variables to be able to get a definitive answer on how long the "feet" need to be, but if you guestimate the dimensions of the fence in the photo and multiply up to your possible heights it would at least give you a starting point.
>
> I'm thinking about putting support braces in the photo like the picture - do they have to be on both sides of the fence and what size and height does the brace have to be?
>
>
>
Yes you need braces, yes they need to extend outwards on both sides of the fence because wind loading can come from either side.
My guess is if you make the fence the full 8' tall and scale the supports up the feet would end up much too long to be practical. Anything much longer than those shown could be awkward to move around.
As an alternative you could add weight to the bottom of the fence, with concrete blocks1. I'd suggest you not permanently attach them as that would make the fence far too difficult to move around, but instead arrange things so they can be moved separately.
You might try a combination of both these things, with feet approximately the same as those in the photo but with weights added on top to make the design more bottom-heavy.
---
(1) At the most simple you could use existing concrete building blocks but if you want to make something that fits the supports of your fence you could cast your own blocks to neatly straddle the "feet" using a form. This form can be a simple plywood box, well lubricated or covered in plastic. A full guide to doing this is beyond the scope of this SE but there are now many guides online to casting concrete at home. Just as a design suggestion, I think you'd want to cast in a piece of bent rebar on the top or on one or both sides to act as a handle.
If you go ahead with casting a better system would probably be to have the posts of the fence simply sit into hollows formed in cast concrete blocks, so the fence would stand much the same as when it's set into the ground conventionally. | Don't try to guess how much wind will force your fence and how wide feet would be needed and how much weights adds to the equation.
Instead figure out a way (construction) to adapt (change) the feet (and weights) to what you observe (learn). |

Well, for a start it can break code that relies on being able to dynamically load classes and resources. It is also possible this kind of thing could be used to break security sandboxes.

32,704 | During my job search, I found [Glassdoor](http://www.glassdoor.com) to be a very useful tool for getting to know about the companies I was searching for. I'd like to give back to that and submit my own reviews to help others.

Currently the company's listing on Glassdoor has only one review (a glowing description of the company by someone with a "manager" position, which only one person in this area has).

If I choose to give a negative or neutral review, I'm sure they wouldn't like knowing that I wrote it. If the review were 100% glowing, the company probably wouldn't care.

I personally also would be wary of giving any credence at all to anything posted on Glassdoor. I have seen plenty of places where most people were happy but there was someone who felt put upon who posted this sort of garbage but if you knew the situation from outside, you would know he wasn't treated unfairly and the the company wasn't a horrible to place to work.

It's not clear what your motivation for leaving a review might be, and clearly you don't want to leave a positive review, but there are several possibilities here.
1. Leave a review anyway. Pour your heart out, assuming all the while that your employer will read the review and know that it is you. Be prepared to have a conversation with your employer should they choose to question you about your statements.
2. Anonymize your review. Remove anything that would specifically tell the reader that it was you who wrote it. Don't include your title, or salary, your location, or any other identifiable data. If necessary, put in false information for those fields, as they likely add nothing to your narrative anyway. Then, if your employer reads it and asks the entire company who wrote it, don't confess. And if asked specifically if you wrote it, lie and say "No".
3. Wait until you leave the company sometime down the road. Then write your review.
4. Don't write a review. Skip your desire to write about this company. |

I have seen plenty of places where most people were happy but there was someone who felt put upon who posted this sort of garbage but if you knew the situation from outside, you would know he wasn't treated unfairly and the the company wasn't a horrible to place to work. Good reviews are also suspect because they could be from people who are trying to make the company look better as part of their job. | * No, they don't know. unless you share full details of you or about any
particular the incident that happened in the company.
* Be honest with your reviews,
* try to post anonymously,
* And glassdoor doesn't reveal your identity to anyone. |
32,704 | During my job search, I found [Glassdoor](http://www.glassdoor.com) to be a very useful tool for getting to know about the companies I was searching for. I'd like to give back to that and submit my own reviews to help others.
However, my most recent job is at a small company. Currently the company's listing on Glassdoor has only one review (a glowing description of the company by someone with a "manager" position, which only one person in this area has). If I were to give a review, the company would instantly know who I am based on my position and location.
If I choose to give a negative or neutral review, I'm sure they wouldn't like knowing that I wrote it. If the review were 100% glowing, the company probably wouldn't care. However, Glassdoor does have a goal of hosting anonymous reviews, so positive or negative, it does seem to go against the spirit of the site. Plus, I'd like to avoid any self-censorship from knowing that I can be identified.

] | I find Glassdoor to be invaluable in reviewing companies, though not infallible. Your issue is one I've stumbled across a few times where I've worked or contracted with a small company and want to leave a review.
Some points to consider:
* If there's only one review on the site, the odds are no one at the company is looking at it. This would make your review less risky in my opinion.
* If you are worried about retribution for a poor review, I would wait until you have left the company to place the review. And consider if you work in a small IT world (like a small city) and burning this bridge may come back to you.
* Consider anonymizing your review as much as possible. Don't specify title or location. If you are asked about it, **in my opinion** you have the right to lie and say it wasn't you. **I know that recommending lying on this site is very controversial, and I will never suggest it unless it is justified!** In my opinion, every employee has the right to give other potential employees a heads-up about an employer. Your employer has no right to go after you for a review you publish **on your own time** and on a third-party site.
* Don't mention any secret or company-specific/intellectual property issues in your review. That's cause for them to look deeper and may give them legal justification.
To sum it up, I suggest putting in a review, but carefully word it based on my suggestions above. Help fellow job seekers to get the information they need to make a job decision before they get hired on. | If you are going to stay more in that company, **never ever leave negative feedback**. Full stop. This will only go against you. Even if you are not the **single** employee in that position, reducing the chances to two or three people is too risky.
You might be recognized as the author even in the future. For example if for whatever reason you *unwillingly* show you know Glassdoor more than your coworkers.
Legally
-------
Your boss may or may not do anything to you. In my country he may fire you without a valid reason if total employees are < 15. Otherwise the company is not enough "small", but there could always be ways for premature termination.
Practically
-----------
You might be subject to mobbing/stalking. That is a crime under several regulations but is extremely hard to prove.
Examples of mobbing are under-assignements, or under-qualification of assignements. It is difficult to prove that such behaviour originates from an harassment.
If you are going to leave your company, you can honestly write whatever you deem useful. Please, for respect of the others before the law, don't exagerate or say false. Defamation is a crime for a reason. Be objective, keep proof for yourself, use facts |

If you are so sure of being identified, and your review may hurt you within the company, I would suggest avoiding that. Anyway, all job seekers don't take reviews to their heart and are not strict believers, it is just taken as a suggestion.
If the review is a positive one, or neutral even, then getting identified is not bad at all, isn't it?
**Based on new edits to the question:**
If you want to follow the spirit, there are a few things you can do.
1. Just hide one of your location or job title. This is possible on glassdoor if this will make identifying you difficult.
2. You can post totally an anonymous response as well without going through a self censorship policy of yours.
With these options available, I think you can achieve what you are seeking. |
970,443 | I need to extract code (but not data!) from classic win32 exe/dll files. It's clear I can't do this only with extraction of code segment content (because code segment contains also the data -- jump tables for example) and that I need some help from compiler.
\*.map files are nice but they only contain addresses of functions, i.e. the safest thing I can do is to start at that address and to process until the first return / jump instruction (because part of the function could be mentioned data)
\*.pdb files are better but I'm not sure what tools to use to extract information like this -- I took a look at DbgHelp and DIA SDK, the latter one seems to be the right tool but it doesn't look very simple. So my question/questions:
1. To your knowledge, it is possible to extract information about code/data position (address + length) only via DbgHelp?
2. If the DIA SDK is the only way, any idea what should I call for getting information like that? (that COM stuff is pretty heavy)
3. Is there any other way?
Of course my concern is about Visual Studio, C/C++ source compilation in the first place.

I have no problem with methods declared inline in a header in some cases - a struct's constructor, a simple method where inlining *measurably* makes it faster (we have some math functions like this), etc. But the liberal use of inlined methods for no apparent reason is:

* Makes it hard to find the implementation of a method (especially searching through a tree of classes for a virtual function, only to find one class had its version declared in the header...)

1,602,436 | I was wondering if anybody could give me ballpark figures for translating resx files. Let's say I have 10 Resx files with each about 10K words. What would be the cost to translate those from English to Spanish (or English to German)?
For the details, we are using Infragistics controls in our application. IG does not provide their software and controls in any other language than English (another reason not to use them... but that's a long story). The way they require to do localizable strings is a pain at best and we are looking at an approach that would be a bit more automated. The side effect is that we would have *all* strings resources localizable. One of the argument against that is the additional effort for 3rd parties that deliver our systems in a different language appears more significant. We are trying to weigh the pros and cons of either approach. (The *other* approach is to *manually* identify which strings do need to be localized and to manually create the code that allows that).

] | A ballpark would be .10~.20 USD per word.
You need to be careful when translating resx files, especially if translatable and do-not-translate content is mixed together. There are tools like [Alchemy Catalyst](http://www.alchemysoftware.ie/products/alchemy_catalyst.html) and [Lingobit Localizer](http://www.lingobit.com/index.html) that can help you and your translators manage these resources better.
For example, in Catalyst, a developer could go through each resx file and *lock* certain strings to protect them from the translator. | As far as pricing is concerned: <http://www.proz.com> is a excellent translators forum. It's probably the best place to start with. |

On click, it displays the concerned questions.
But, if I'm not wrong, I never saw this on SO before.
I guess it's because there is a lot more activity on SO, and "67 new questions with activity" wouldn't be that good.
Yet, is there any way to activate it on SO ?
And if not, wouldn't be useful to add such a feature for the "interesting" tab only, which is more likely to have less activity ?

218,332 | Is this sentence, "I wish I had a little less problems" grammatically correct? Especially the phrase, "... a little less problems". I know there are other ways to say the same thing like, "I wish I didn't have as much problems" or "I wish I had less problems" but it changes the feel of the sentence. The feel I'm tryna give off with this sentence is that the person has so many issues that he's wishing that AT LEAST something was right.
Btw, is the title grammatically correct?
Edit: Thanks Juhasz, this surely is an issue of countable and uncountable thing. But that didn't solve my problem cause in the sentence I'm not only using 'less' but 'a little' also.
Edit: So, this is what I'm actually writing: "It's hard to live in a world where everyone seems perfect and you spend your day wishing you had **a little less problems**". Now, I can't find something that quite goes with the flow. | 2019/07/15 | [

] | I would write *"I wish I had **fewer** problems"*.
In theory, **less** is supposed to be used to describe a smaller amount of a single entity, while **fewer** is supposed to be used to describe a smaller number of entities.
In practice, what you have written is likely to be understood, if a little awkward.
For more casual speech, I might also suggest:
* *"I wish I didn't have quite so many problems."* (the reversal feels more natural to me, and the use of *quite* indicates that there is only a small adjustment needed)
* *"I wish I had a little less on my plate"* (*on my plate* is an idiom for *things to do*, so might not be a direct translation, but certainly understandable)
* *"I wish I didn't have quite so much on my plate"* (a combination of the two is also valid)

PS: There is nothing wrong with the the title of your question (assuming it still reads **"… a little less problems" – is this phrase grammatically correct?**). Quoting the problematic phrase makes it clear that we are referring to the the phrase, and the question at the end is fine. | The following would apply to normal phrasing:
>
> ✔ fewer problems
>
> ✘ less problems
>
>
> ✘ fewer of a problem
>
> ✔ less of a problem
>
>

The use of adjectives should not be influencing the word used.
In other words, I would say one of the following:
>
> 1. a little **less** ***of a problem***
> 2. a little **fewer** ***problems***
>
>
>
However, the specific phrase *a little fewer problems*, while analytically correct, seems idiomatically strange.
In short, I would pick 1. over 2.
So:
>
> I wish I had fewer problems. OR
>
> I wish I had a little less of a problem.

224,000 | Is it generally better to have a small number of fully upgraded rooms? Or have a larger number of not-so-upgraded ones? (Provided of course, that we have Power to spare.)
Wondering if the massive costs for upgrading are worth it. For example, I had a dweller training in a level 2 Strength Center with 2.00 hours to go. Then paid 4500 to upgrade it. The remaining time just went down by about 10 minutes! This seems pretty crazy since I could have built another 3-4 rooms with this cash. | 2015/06/17 | [

] | I won't upgrade those rooms. You have later more than enough people to get others for hours in the training room. Buy 2-3 rooms and put the people in them instead one fast room. It's much cheaper and efficient.
By the way. You can further improve this. Just make a woman pregnant and put her inside the training room (not for the real world :D). This way you get more people while you train the existing ones. ;-) | Up until this point in my progress. All Ive done is upgraded my vault little by little, collecting a few caps, couple of uniforms, and some pretty decent weaponary. Currently on a new game. I've got 25 dwellers, I'm able to maintain my power, food, and my water all at full capacity. I've already got Lucas Simms legendary dweller. He came to me right at the beginning of the game at level 36 in a lunch box. He's level 50 now. My max level for my common dwellers as of now are somewhere around 18-24. I've also taking the time and put in quite a bit of effort to upgrade my Gym 3 times, and let me just say WOW! that took for ever. I sent my legendary dweller out into the wasteland roughly for about 2 days 6 hours. I simply ran out of stim packs. I didn't want to risk funding such an attrosish fee of caps for Lucas Simms an his stats, all 80 of the items he found out in the waste land. So I brought him back before he made it to the armoury out in the waste at the 60:00 hour mark. Well, at least all 25 of my dwellers are now fully locked and loaded, and fully equipped with the nessacary uniforms in association to their corresponded rooms. Plus many extras. I've been taking this slow as in any fallout game. You simply just can't take it on all at once. Don't be so quick to upgrade your power, water,and food rooms with. First build 3 rooms side by side, then fill them up with dwellers. My suggestion on the second step is then to upgrade every room. Don't buy the next room simply cause you have enough dwellers to build it. Just know that it will cost power which is a total nuisance to try and cope with. Especially if you don't have enough resources to do so. When this happens we sometimes are forced to rush and what tends to happen quite often is it just failed. And let me state thatfew rushes which halts production and puts everything into chaos, not only slows the timer down but damages your dwellers, especially if your rushing in a fully upgraded room. Not having stim packs will put them into jeopardy because say you rushed. And a fire breaks out, they get hurt, u rush again that fails too, and you do it one more time to see if you can't get it to just magically work for you and nope, that failed too. Now if a fire or infestation happens in that room even though you didn't rush it, and you don't have the stims to revive them, this especially near that start of the game is gonna kill you. I even almost gave up a few times myself but trial and error. So Before you rush, be prepared, always provide the adiquit resources for every scenario in game. Health also has an impact and also regulates to some degree of a dwellers happiness. All I know is for me and my 25 dwellers, happiness is finally raising to 100, four of my dwellers have a strength of 10 only after a few days of waiting. Trust me it will all be worth it. These are going to be some fierce breeding grounds in the next couple days. Lol. I realize I need dwellers, in order to have dwellers I need food and water. Well time to impregnat around 10 females and get my next two rooms in order. A new fully upgraded diner and water treatment plant definatley will require an new power plant. So that's going to be 18 people I've got to be ready to provide for before I even build that stuff. The training rooms lol. I've grasped the concept of this game and I find this really enjoyable. As long as I'm able to continually have in my possession stim packs I should be fine. Rad always are God to have to, I will figure out later just how important they really are. Please Forgive me if this isn't in depth all that much I realize this, I'm just posting my findings so far on this obviously fun and addicting game. I just started playing this after all. |
